Notes

1. Cooling and heating capacities in the tables are determined under the test conditions of JIS B 8627.

Operating condition Cooling Heating (standard) Heating (low temp.)

Indoor air intake temp. 27°CDB/19°CWB 20°CDB 20°CDB/15°CWB or less

Outdoor air intake temp. 35°CDB 7°CDB/6°CWB 2°CDB/1°CWB

• Effective heating requires that the outdoor air intake temperature be at least –20°CDB or –21°CWB.

2. Gas consumption is the total (high) calorific value standard.

3. Outdoor unit operating sound is measured 1 meter from the front and 1.5 meters above the floor (in an
anechoic environment). Actual installations may have larger values due to ambient noise and reflections.

4. Values in parentheses ( ) for refrigerant gas and liquid types are those when the maximum piping length
exceeds 90 meters (equivalent length). (Reducers are available locally.)

5. Specifications are subject to change without notice.

6. Hot water heating capacity is applicable during cooling operation as in Note 1.

7. The maximum water temperature that can be obtained is 65°C. Water heating performance and temperature
vary with the air conditioning load.

Because the hot water heating system uses waste heat from the engine, which runs the air conditioning,

its ability to heat water is not guaranteed.

1. Cooling and heating capacities in the tables are determined under the test conditions of JIS B 8627.

Operating condition Cooling Heating (standard) Heating (low temp.)

Indoor air intake temp. 27°CDB/19°CWB 20°CDB 20°CDB/15°CWB or less

• Effective heating requires that the outdoor air intake temperature be at least –20°CDB or –21°CWB.

2. Gas consumption is the total (high) calorific value standard.

3. Outdoor unit operating sound is measured 1 meter from the front and 1.5 meters above the floor (in an
anechoic environment). Actual installations may have larger values due to ambient noise and reflections.

4. Values in parentheses ( ) for refrigerant gas and liquid types are those when the maximum piping length
exceeds 90 meters (equivalent length). (Reducers are available locally.)

5. Specifications are subject to change without notice.

6. Hot water heating capacity is applicable during cooling operation as in Note 1.

7. The maximum water temperature that can be obtained is 65°C. Water heating performance and temperature
vary with the air conditioning load.

Because the hot water heating system uses waste heat from the engine, which runs the air conditioning,

its ability to heat water is not guaranteed.

System Design

1. System Configuration

(1) Procedure for selecting model type and calculating performance

Perform the following procedures to select a model type and calculate performance capabilities.

Calculate indoor A/C load

Select A/C system

Design the control system

Select the indoor unit type

Provisionally select indoor/-

outdoor unit combination

Correct performance for

indoor/outdoor performance

ratio

Check piping length and

mounting height difference

between indoor and outdoor

units

 Calculate the maximum A/C load for each room or zone.

 For each room or zone, select the most suitable air

conditioning method using GHP.

 E.g., Individual, centralized or centrally monitored control

(see the section on Control Information document)

 Select the appropriate indoor unit type for the A/C system,

e.g., ceiling cassette, all-duct built-in-ceiling, ceiling-mount,
kitchen, or floor-mounted type.

 Indoor units with up 130% of outdoor unit capacity can be

connected.
* Up to 24 indoor units can be connected to an outdoor unit.

 If the total capacity of the indoor units exceeds outdoor unit

capacity, apply a performance correction.

 Because outdoor unit limitations are model-dependent, be

sure to locate the equipment so that the specified tolerances
for refrigerant piping lengths and mounting height difference
are maintained when allocating units.

Correct performance for pipe

length, height difference and

ambient conditions

Reconfirm combined

performance of indoor and

outdoor units

Determine the piping layout

Calculate the additional

charge amount

Design wiring to handle

system capacity

 Make performance corrections for ambient air conditions,

piping lengths (effective length), and mounting height
difference.

 If a provisionally selected model type is inadequate after

performance corrections, reconsider your configuration.

 Design the pipe layout so as to minimize the required

amount of additional refrigerant charge.

 If system expansion is contemplated, include those

considerations in the design.

 Calculate the amount of additional refrigerant charge

from the diameters and lengths of refrigerant pipes on the
refrigerant pipe system drawing and the unit additional
charge amount.

 Check the minimum indoor performance capability and

floor area (density limit) for the amount of refrigerant. If the
density limit is exceeded, reconsider ventilation equipment.

 Select wiring capacity according to power supply capabilities.
There are limitations if indoor and outdoor units are powered

from a bus system. If a bus system is employed for the indoor
units, consider including the outdoor unit(s) in the system
as much as possible.

(2) Calculation of actual performance

Indoor units with up 130% of outdoor unit capacity can be connected.
* Up to 24 indoor units can be connected to an outdoor unit.
Multi-unit air conditioning system performance depends on ambient temperature, piping lengths and
mounting height differences, so each correction factor should be taken into account when selecting
the model type.

(1) Dependence of Multi-unit air conditioning system performance on installation conditions

Note 1. Outdoor unit rated total cooling capacity (see the outdoor unit specification table) is the

cooling capacity under JIS conditions (indoor side: 27°CDB, 19°CWB, outdoor side: 35°CDB,

-°CWB)

Note 2. Outdoor unit rated total heating capacity (see the outdoor unit specification table) is the

heating capacity under JIS conditions (indoor side: 20°CDB, -°CWB , outdoor side: 7°CDB,
6°CWB)

Note 3. Read the rated cooling capacity of the applicable indoor unit from the indoor unit specification

table.

Note 4. Read the rated heating capacity of the applicable indoor unit from the indoor unit specification

table.

Note 5. Read the rated cooling capacity of the applicable indoor unit from the indoor unit specification

table, and obtain the total for all units..

Note 7

Note 7

Note 6. Read the rated heating capacity of the applicable indoor unit from the indoor unit specification

table, and obtain the total for all units..

Note 7. Read the percentage data at the required temperature from the relevant capacity table in the

“Model Basic Data Table” for the outdoor unit, and divide by 100. (Contact your Panasonic
business representative for the Model Basic Data Table.)

*In the case of two outdoor units, calculate as follows:

Σ (Correction factor for outdoor unit × rated capacity of outdoor unit)

System correction factor =

Σ (Rated capacity of outdoor unit)

Example) Connecting two units (A/C)

α1 = Correction factor of outdoor unit 1, W1 = Rated cooling capacity of outdoor unit 1
α2 = Correction factor of outdoor unit 2, W2 = Rated cooling capacity of outdoor unit 2

System correction factor =

α1 × W1 + α2 × W

W1 + W

between outdoor and indoor units (positive when the outdoor unit is higher, and negative
when the indoor unit is higher). Read the correction factor from the “Performance correction
for refrigerant piping length” for the outdoor unit, and divide by 100 for percentage.

(2) Example of calculation of actual performance

[Example calculation conditions]

Indoor units: Six type 112 units, and four type 140 units
Outdoor units: Two type 560 WMulti outdoor units
Indoor/outdoor temperatures: cooling (indoors 22°CWB, outdoors 33°CDB); heating (indoors
22°CWB, outdoors 3°CDB)
Height difference between indoor/outdoor units: Outdoor unit is higher by no more than 50m
Refrigerant effective piping length: 120m

1. System Configuration

1) Indoor unit cooling capability

Outdoor unit rated cooling capacity
Indoor unit rated cooling capacity

Note 1

= 56.0 + 56.0 = 112.0 (kW)

Note 3

Type 112 = 11.2 kW, type 140 = 14.0 kW

Total rated cooling capacity of indoor units

Note 5

= 123.2 (kW)

11.2×6+14.0×4=123.2

From the performance table, the correction factor for temperatures and connected capacity

Note 7

= 1.08
The connected capacity of the indoor units as a percentage of the outdoor capacity is (123.2 ÷ 112.0) × 100 = 110%.
Next obtain the correction factor for each outdoor unit. From the 110% air conditioner capacity
table for each outdoor unit, note the value at the crossover point of the indoor wet bulb temperature
22°CWB and the outdoor air temperature 33°CDB, and then divide the value by 100.

The correction factor for type 560 outdoor units is: 107.9% 1.079

1.079 × 560 + 1.079 × 560

System correction factor = = 1.08

The correction factor for piping length

560 + 560

Note 8

= 0.86
From the “Performance correction for refrigerant piping length” table for the selected unit type, note
the crossover point for the equivalent length of 120m and the height difference of 50m, which is
86%, and divide this by 100.
a) Cooling capacity of each indoor unit
Indoor unit type 112 cooling capability = Note 1 × Note 3 ÷ Note 5 × Note 7 × Note 8
= 112.0 × 11.2 ÷ 123.2 × 1.08 × 0.86
≅ 11.0 kW
Calculating the same way, Type 140 provides 13.7 kW.
b) Total cooling capability of the indoor units is therefore 11.0 × 6 + 13.7 × 4 = 120.8 kW.

2) Indoor unit heating capability
Outdoor unit rated heating capacity
Indoor unit rated heating capacity

Note 1

= 63.0 + 63.0 = 126.0 (kW)

Note 3

Type 112 = 12.5 kW, type 140 = 16.0 kW

Total rated heating capacity of indoor units

Note 5

= 139.0 (kW)

12.5 × 6 + 16.0 × 4 = 139.0

From the performance table, the correction factor for temperatures and connected capacity

Note 7

Indoor unit selection was based upon cooling capacity, so the connected capacity of the indoor
units as a percentage of the outdoor unit capacity is (123.2 ÷ 112.0) × 100 = 130%
Next obtain the correction factor for each outdoor unit. Read the values for 22ºCWB from the 110%
heating capacity table for each outdoor unit, and the value in the table for outdoor temperature of
3ºCDB, and divide by 100.
The correction factor for type 560 outdoor units is: 102.5% 1.025

1.025 × 63.0 + 1.025 × 63.0

System correction factor = = 1.025

The correction factor for piping length

63.0 + 63.0

Note 8

= 0.954
From the “Performance correction for refrigerant piping length” table for the selected unit type, note
the crossover point for the equivalent length of 120m and the height difference of 50m, which is

95.4%, and divide this by 100.
a) Heating capacity of each indoor unit
Indoor unit type 112 heating capability = Note 1 × Note 3 ÷ Note 5 × Note 7 × Note 8
= 126.0 × 12.5 ÷ 139.0 × 1.025 × 0.954
≅ 11.6 kW
Calculating the same way, type 140 provides 14.8 kW.
b) Total heating capability of the indoor units is therefore 11.6 × 6 + 14.8 × 4 = 128.8 kW.

[Anticipating additional indoor units]

1) Ball valve installation position: Install on main piping after branching.

2) Installation guidelines

• Slope main pipes after branches so as to prevent oil buildup.

• Locate ball valves as close as possible to (within 40 cm) of their branch points.

• If the pipe diameter at the ball valve is smaller than that of the main pipe after branching, install
reducers only at the ball valve connections.

• Locate the equipment where it will be easy to operate and inspect in the future.

Caution

When installing indoor piping (including that for future indoor expansion) along a main pipe after a
branch, be sure to position service ports to face in the direction of their units (see dashed lines in the
example above).

1) Ball valve installation position: Install on main piping after branching.

2) Installation guidelines
* Slope main pipes after branches to prevent oil buildup.
* Locate ball valves as close as possible to within 40 cm of their branch points. If the pipe diameter

at the ball valve is smaller than that of the main pipe after branching, install reducers only at the
ball valve connections.

* Locate the equipment where it will be easy to operate and inspect in the future.

Caution

* When installing indoor piping (including that for future indoor expansion) along a main pipe after a

branch, be sure to position service ports to face in the direction of their units (see dashed lines in the
example above).

* Install a service port between the branch and solenoid valve kit, and with additional solenoid valve kits

when expanding indoor units.

2) Be careful to charge accurately according to refrigerant weight.

3) Charging procedure

Evacuate the system, close the gauge manifold at the gas pipe side to ensure that no refrigerant enters

the gas pipe side, then charge the system with liquid refrigerant at the liquid pipe side. While charging,
keep all valves fully closed.

The compressor can be damaged if liquid refrigerant is added at the gas pipe side.

4) If the system does not accept the predetermined quantity of refrigerant, fully open all valves and run
the system (either heating or cooling). While the system is running, gradually add refrigerant at the low
pressure side by slightly opening the valve on the cylinder just enough so that the liquid refrigerant is
gasified as it is sucked into the system. (This step is normally only needed when commissioning the
system.)

All outdoor unit valves should be fully open.

5) When charging is completed, fully open all valves.

6) Avoid liquid back-flow when charging with R410A refrigerant by adding small amounts at a time.

Notes

• When charging with additional refrigerant, use liquid only.

• R410A cylinders are colored gray with a pink top.

• Check whether a siphon pipe is present (indicated on the label at the top of the cylinder).

• Depending on refrigerant and system pressure, conventional refrigerant (R22, R407A) equipment may

or may not be compatible with R410A equipment, so care is needed. In particular, the gauge manifold
used must be specifically designed for R410A.

• Be sure to check the limiting density.

• Refer to the section “Opening the shut-off valves” when the instructions call for fully opening all valves.

D-17

System Design

3. Refrigerant piping design

(7) Checking the density limit

The refrigerant (R410A) used in a Multi-unit air conditioning installation is in itself a safe refrigerant that
is neither flammable nor poisonous, but just in case a leak in a small room should occur, steps need to
be taken to prevent gas from exceeding the permissible concentration and causing asphyxiation. The
Japan Refrigeration and Air Conditioning Association have stipulated a threshold concentration for
refrigerants in its publication “Guidelines for Ensuring Safety in the Event of a Refrigerant Leak from a
Multi-Unit Air Conditioning System” (JRA GL-13:2010).

Apart from the lowest level underground, the threshold concentration for the charge in a system has
been set to

total refrigerant/living space capacity ≤ 0.42 kg/m3 (R410A models).

If this condition is not met, the system must either be equipped with two of the countermeasures (alarm,
ventilation or safety shut-off valve) or be redesigned.

Please note, when the system is in the lowest level underground, depending on the type of refrigerant,
the threshold concentration and number of countermeasures required may vary.

For further details, either refer to the technical document JRA-GL-13 or consult with your dealer.

installed for up to 48 indoor units.)

2) Usable indoor unit capacity ranges are:

Minimum: 50% of the minimum capacity of the outdoor units
Maximum: 130% of the total capacity of the outdoor units

(2) Outdoor unit connection conditions (during initial installation, be sure to select piping sizes that will

support the total horsepower after expansion).

1) Outdoor units other than those indicated above cannot be used for expansion. (Doing so may result

in a failure.)

2) During initial system installation, be sure to consider the requirements for indoor unit piping after

expansion.
(3) Select piping sizes according to requirements after expansion. [Refer to section 2, “System Piping.”]
(4) If future system expansion is anticipated, install ball valves (sold separately) at the outdoor and indoor

unit sides of the branch pipe. (Figure 1)

1) To prevent oil from being drawn inside, slope piping opposite to flow direction.

2) Locate ball valves as close as possible to the main piping (within 40 cm).

3) If the diameter of the ball valve is smaller than the main piping, install a reducer at the valve.

4) Locate the equipment where it will be easy to operate and inspect in the future.

5. Outdoor unit positioning requirements

(1) Combined installation criteria

If several outdoor units are installed on, for example, the roof of a building, the space required for normal
operating airflow may be insufficient, causing exhaust air from one outdoor unit to be sucked into another,
creating a kind of airflow short circuit. This can cause an increase in the effective ambient air temperature,
impeding cooling capability or even forcing emergency shutdown.
Therefore, when installing multiple GHP units, follow the instruction criteria below to ensure sufficient airflow.
Compared with cooling, the effect on heating is slight, so there should be no problems if the installation
criteria for cooling are satisfied.
Note: In unusual installation circumstances, give these criteria appropriate consideration when making
installation decisions.

(1) Scope of applicability of criteria
These criteria apply to installations in either of the following situations:

• When eight or more outdoor units are installed in combination

• When seven or fewer outdoor units are installed where walls are present that may impede air circulation
(2) Conditions for combined installation
To ensure adequate airflow, the following conditions must be met in combined installations:

• Adequate spacing must be provided between each outdoor unit and between rows of units.

• Adequate clearance for airflow from the surroundings must be provided for the combined outdoor

units.

(3) Parameters for combined installations

[1] Rows of outdoor units

La = Average distance between outdoor units (m)

• When the distance between outdoor units is unequal, La is the average.

• Locate no more than three outdoor units near each other.

Lu = distance between rows (m)

• All distances Lu should be equal.

D-28

System Design

2) Calculate the area of air inflow from surroundings
Calculate the effective inflow area, considering the effect
of surrounding walls.
a) Calculate effective inflow height Hwe

The calculation method depends on the type of wall.
The two types to consider are louvers, which allow
air to pass, and sound barrier walls, which do not.
i). Walls the permit air passage (including the case

of no wall)

• Use the following formula to calculate the
height of inflow,
Ha1 to Ha4 (m) for each wall.
Ha = LW + Hu + 1.5Ht + U
where

Ha = inflow height (m)
LW = Distance from wall to nearest outdoor unit (m)

• Calculate effective inflow height Hwe (m) for each wall. Depending upon wall height and
inflow height Ha, apply one of the following formulae.
For Hw ≥ Ha, Hwe =(Ha – (HU + HH + Ht)) × Xw + (HU + HH + Ht) × Xw × 2
For Hw < Ha, Hwe =(Ha – Hw + [Hw – (HU + HH + Ht)] × Xw + (HU + HH + Ht) × Xw × 2
where Hw = Wall height (m)

• The wall height below the exhaust part (HU + HH + Ht) has twice the weighting of other

parts (inflow wind speed is doubled from 0.5 to 1 m/s).

• When there is no wall, Hwe = Ha.

ii). Walls that block air passage

• Use the following formula to calculate apparent heights Hb1 to Hb4 (m) for each wall.
Hb = Hw – HU – 1.5Ht
where Hb = Apparent height (m) of wall

• For each wall, use the diagram at the right to obtain the effective inflow heights Hwe1 to
Hwe4 (m) for each wall.

b) Calculate effective inflow length Le

From the effective inflow height Hwe calculated for each wall, calculate effective inflow lengths Le1 to Le4.

•

Calculate the effective distance from each boundary surface (wall) to the nearest unit, Lwei (m).

With no wall: Lwei = 6
If Lwi ≥ 6m, then Lwei = 6
If Lwi < 6m, then Lwei = Lwei

• Calculate effective inflow lengths Le1 to Le4 (m) for each wall.
Le1=LN+Lwe4+Lwe
Le2=LM+Lwe3+Lwe
Le3=Le
Le4=Le

c) Calculate effective inflow area

From effective inflow heights Hwe1 to Hwe4 and lengths Le1 to Le4, calculate the effective
inflow area for each wall.
i) Calculate effective inflow area Se1 to Se4 (m) for each wall.

Se1=Hwe1×Le
Se2=Hwe2×Le
Se3=Hwe3×Le
Se4=Hwe4×Le

ii) Calculate the overall effective inflow area, Set (m2).

Set=Se1+Se2+Se3+Se

iii) Calculate the areas of adjoining surfaces.

Se12=Se1+Se
Se23=Se2+Se
Se34=Se3+Se
Se41=Se4+Se

3) Judge the inflow area
From the required inflow area calculated in 1), and the effective inflow area calculated in 2)-C),
satisfy the following two conditions.

1) Overall effective inflow area (Set) must be greater than required inflow area Sr.

2) In an array with three or more rows, the smallest value of inflow area of two adjoining walls
(Se12, Se23, Se34 or Se41) must be greater than 25% of Sr: Min(Se12, Se23, Se34 or Se41) ≥

0.25 × Sr

If these conditions are not satisfied, apply the following measures, and recalculate.

• Increase mounting height

• Install exhaust ducts

• Change from pads to catwalk mounts

• Increase wall opening size

• Lower the height of walls

• Increase the distance from walls to units

(6) Correction of cooling capability

By meeting these criteria, the temperature of the intake air in this combined installation is expected
to rise by 3ºC during cooling.

5. Outdoor unit positioning requirements

(2) Verandah installation criteria

If outdoor units are installed on a verandah where they are surrounded (by walls and ceiling) on five sides,
the design layout must take into account short-circuit airflow and maintenance space requirements. Evaluate
the installation on each floor of a building in the same way.

(1) Design points

1) Do not allow the exhaust air from an outdoor unit to recirculate, as this would seriously degrade
system performance.

2) Do not install a gallery on the exhaust outlet. (Installing a gallery reduces airflow by over 10%.)

3) Create an environment in which exhaust air from the outdoor unit will not cause any problems.

4) Comply with local regulations regarding operating noise from outdoor units.

5) Distance to the nearest building should be at least 10m.

6) Design external air conditions are based on ambient temperature of 35ºCDB or less.

7) Make certain to provide adequate maintenance space.

(2) Necessary inflow area

1) For an installation like that of Figure 1, the shaded area indicates the inflow area.

2) The necessary inflow area for one 13- to 25-HP outdoor unit is 12.7m2, so the shaded area is the
necessary inflow area

(3) Maintenance space

Provide maintenance space with the dimensions in Figures 1 and 2.

6. Sound-proofing measures

(1) Installation location and sound-proofing measures

If no suitable installation location is available and it is necessary to install in a confined location where there
are houses, offices or other buildings nearby, it may be necessary to provide sound barrier walls, sound
absorption chambers or other secondary sound-proofing measures.
Secondary sound-proofing measure include:

• Attenuation over distance

• Sound-proofing with noise barriers

• Sound-proofing using sound absorbing chambers

• Sound-proofing by vibration isolation (anti-vibration pads, flexible couplings, etc.)

The following criteria are from Tokyo Pollution Prevention Regulations.

(2) Attenuation of sound over distance

The figure at the right shows sound attenuation
over distance. (Figure 1)
Operating sound is measured 1m from its source.

Example. For a type 280 outdoor unit, the sound

level in the 50-Hz range at 3m distance
is specified as 56 dB(A). In Figure 1,
follow the 3m distance line downwards
to where it crosses the slope (a), and
then horizontally to point (b) at the left
to find the attenuation of 6.8 dB(A).

Therefore, 56 – 6.8 = 49.2 dB(A)

 The barrier should be sufficiently higher than the top of the outdoor unit. (Figure 3)
(However, not more than 1m higher.)
 The width of the barrier should be at least several times the height, on both sides of the center. Where

this is not possible, the barrier should bend around the unit as shown in Figure 4.

 The barrier should be located as close as possible to the outdoor unit (sound source). (Figure 3)

(4) Additional sound from reflections

 Operating sound from outdoor units reflects from the walls of building and ground surfaces. These

reflections are received at the reception point, increasing the sound level of the system.

 The sound received at the reception point is the sum of the sound propagated directly from the source

plus reflected sound.

The reflected sound level is obtained by establishing a virtual sound source (A'), and estimating the

sound level at B from A' (subtract the distance attenuation over the path A'-B). See the next paragraph
on combining sounds for a description of how to add direct and reflected sounds.

point is determined by combining the sounds from each unit.
The combined sound from n units L1, L2, …Ln is expressed
by the following formula.
If L = the combined sound level,

L = 10 log10 (10

L = 10 log10 (10

)

This for of expression is applicable for any value of n.
Although sound level can be calculated this way, for simplicity,
we have prepared graphs to use instead.

<Calculation Example 1>
Calculate the combined sound level of L1 = 62 [dB] and L2 = 61 [dB]. L1 – L2 = 62 – 61 = 1 [dB], the correction
value from Figure 5 is 2.5 [dB], and 62 + 2.5 = 64.5 [dB], so the combined sound level is 64.5 [dB].

<Calculation Example 2>
To combine sound levels of 60, 64, 63 and 65 dB, first sort the values in order of magnitude.
65, 64, 63 and 60 dB
Then combine 65 and 64 dB to obtain the difference, 65 – 64 = 1 dB, which has a correction value of 2.5
dB, and 65 + 2.5 = 67.5 dB.
Next, combine 67.5 and 63 dB for a difference of 4.5 dB, for which the correction value is 1.3 dB, and 67.5
+ 1.3 = 68.8 dB.
In the same way, combine 68.8 and 60 dB for level difference of 8.8 dB, for which the correction value is

0.5 dB.
And finally, 68.8 + 0.5 = 69.3 dB, which is the combined level of the four sounds.

Difference = 1

Correction value = 2.5
65+2.5=67.5

Difference = 4.5
Correction value = 1.3

67.5+1.3=68.8
Difference = 8.8

Correction value = 0.5

Octave band Hz 63 125 250 500 1000 2000 4000 8000

Conversion factor dB –26 –16 –9 –3 0 +1 +1 –1

Using the above table, the A weighting is obtained by adjusting the calculated value for each band by its
conversion factor. These values are then combined in order of magnitude, as shown in the following example,
to obtain the overall A weighting.

<Calculation example>
The octave band levels (dB) are obtained from the frequency analysis table (the operating sound level at
the center frequency of each octave band). These values are corrected with the A weighting correction
factor to obtain the A weighting. The following calculation determines the operating sound level.

Octave band Hz 63 125 250 500 1000 2000 4000 8000

Octave band level dB 69 66 62 59 56 49.5 45 41.5

A weighting dB(A) 43 50 53 56 56 50.5 46 40.5

These A-weighting values are combined one-by-one in order of magnitude (in the same away as combining
different operating sounds).

Difference = 14.75

60.75+0.1=60.85

Difference = 17.85

60.85+0.1=60.95

No further calculation necessary

The overall A weighting is thus calculated to be 60.95 dB(A).

(7) Designing sound-proofing countermeasures

<Calculation example>
In the installation drawing at the right, a scheme to suppress
operating sound at the reception point is required.
First, determine the operating sound level of the outdoor unit at
each frequency. By applying this information to Table 1, the sound­proofing calculation sheet, sound attenuation and additions are
calculated for the installation.
