Design Features

The Daikin air-cooled, scroll compressor units are a product of Daikin’s commitment to offer quiet, reliable, energy efficient equipment. These units incorporate high quality compressors, state-of-the-art coil design, and innovative packaging.

Construction

Factory assembled and mounted on a heavy-gauge steel channel base. The base rails, supports and cabinetry are powder-coat painted. The base distributes the unit weight for roof loading. Varied and convenient installation is possible by virtue of the unit's small footprint.

Compressors

Copeland’s Compliant Scroll tandem compressors are used. These rugged hermetic compressors are constructed with an integral cast iron frame, cast iron scrolls, three Teflon impregnated bearings, and three oil filtration devices for each compressor.

Using Copeland's Compliant Scroll tandem compressors provides two steps of capacity modulation. One compressor can run alone, depending on the load of the system, utilizing the entire unit’s condenser surface, which results in excellent part-load efficiency. The refrigerant circuit has specially designed oil and gas equalization lines to control oil migration.

The design also offers radial and axial compliance (no tip seals), a large internal volume for liquid handling, a removable suction screen, and a rotary dirt trap and oil screen. In addition, the compressor is self-compensating for wear, handles liquid and debris, and inherently yields the highest efficiency for its class.

This well protected compressor includes a solid-state motor protection module, 4 individual motor-winding sensors, a patented internal discharge temperature probe, and a patented shutdown feature that prevents reverse rotation. An internal discharge check valve helps prevent shutdown noise and comes standard with high and low pressure taps with Schrader valves, a sight glass, an oil level adjustment valve, and an off cycle crankcase heater.

Units are available in 60 Hertz electrical voltage configurations from 208 to 575 volt operating at 3500 rpm.

Condenser Coils

Condenser coils have internally enhanced seamless copper tubes arranged in a staggered row pattern. The coils are mechanically expanded into Daikin lanced and rippled aluminum fins with full fin collars. A variety of optional coil material and coatings are available for corrosive atmospheres. The external condenser coils are fitted with a protective wire mesh guard as standard equipment.

Condenser Fans and Motors

Multiple direct-drive, dynamically balanced, propeller fans operate in formed venturi openings at low tip speeds for maximum efficiency and minimum noise and vibration. A heavy-gauge vinyl-coated fan guard protects each fan.

Each condenser fan motor is heavy-duty, 3-phase, Totally Enclosed Air Over (TEAO) with permanently lubricated ball bearings and inherent overload protection. SpeedTrol option includes a single-phase motor with fan speed control on the lead fan.

Evaporator

Stainless steel, brazed plate evaporators are used on the AGZ units. They have counter-flow operation and very high efficiencies.

Catalog 616

Electrical Control Center

Operating and equipment protection controls and motor starting components are separately housed in a centrally located, weather-resistant control panel with hinged and tool-locked doors.

Control System

The MicroTech II systems available today on this class of equipment. This powerful, user-friendly control system provides the flexibility and performance needed for either stand-alone unit operation or the controller can be easily tied into your building automation system of choice using Daikin’s exclusive Open Choices feature that allows you to choose from open standard protocols such as BACnet, Modbus, and LonTalk to communicate easily with the building automation system that best meets your facility requirements. These optional communications modules are available factory-installed or can be easily field installed.

MicroTech II’s state-of-the-art design will not only permit the unit to run more efficiently, but will also simplify troubleshooting if a system failure occurs. Every MicroTech II controller is programmed and tested prior to shipment.

Operator-friendly

The MicroTech II control menu structure is separated into four distinct categories that provide the operator or service technician with a full description of current unit status, control parameters, and alarms. Security protection helps prevent unauthorized changing of the setpoints and control parameters.

MicroTech II continuously performs self-diagnostic checks, pressures and protection devices, monitoring system temperatures, and it will automatically shutdown a compressor, or the entire unit, if a fault occurs. The

cause of the shutdown will be retained in memory and can be easily displayed in English or metric units for operator review.

The MicroTech II unit controller can also retain and display the time that the fault occurred and the operating conditions that were present at the time of the fault, an extremely useful feature for troubleshooting. In addition to displaying alarm diagnostics, the MicroTech II controller also provides the operator with a warning of pre-alarm conditions. Alarm notification data can also be passed on to your BAS through an optional communications module.

Staging

On ACZ condensing units, temperature control for the system is provided by the installer through a field supplied temperature controller. The field-supplied staging signals are provided to the MicroTech II controller which correspondingly activates and deactivates the scroll compressors. The temperature controller is required to close normally-open 24 volt contacts on a demand for cooling. These closure signals are field wired to the terminal strip (TB2) in the condensing unit. Refer to the typical field wiring diagram on page 34

wo control stages are required:

for details.

Lead/lag is automatic and switched based on operating hours and compressor starts.

Equipment Protection

The unit is protected in two ways: (1) by alarms that shut the unit down and require manual reset to restore unit operation and (2) by limit alarms that reduce unit operation in response to some out-of-limit condition. Shut down alarms can activate a remote alarm signal. Limit alarms activate a signal on the controller.

ACZ Condensing Unit Performance

Selection Procedure

ACZ condensing units are selected in conjunction with some kind of evaporator equipment. The ACZ ratings are based on saturated suction temperature at the compressor inlet and on ambient air dry-bulb temperature. For a system selection, the ACZ condensing unit is usually selected first, and then the line loss added to the condensing unit saturated suction temperature to determine the saturated evaporating temperature. This temperature is then used for the selection of the evaporator, whether it is a DX cooling coil or water heat exchanger. The pipe size can be determined from procedures and data in the Refrigerant Piping Section. For selection purposes, the tubing size is based on a pressure equivalent of a two-degree F line loss (equal to about 3-psi pressure drop).

uired job capacity by

The correction for altitude found in Table 1 is applied, if applicable, by dividing the re the correction factor to ascertain the necessary unit capacity in the Capacity Tables.

R-407C NOTE: R-407C is an azeotrope and as such has a glide characteristic. An evaporator mid-point temperature will be about four-degrees higher than the dew point temperature. For example, an R-22 evaporator selected at a 40F evaporating temperature would be comparable to 44F with R-407C.

Selection example, Inch-Pound units

Given:

200 Mbh job requirement 95°F ambient temperature 40F saturated suction temperature 2,000 foot altitude R-22

2. From Table 2 on the following page, an ACZ 020 at th unit power input of 20.0 kW

Correct for altitude:

Capacity: 202.5 Mbh x 0.986 = 200 Mbh

Power: 20.0 kW x 1.009 = 20.2 kW

EER: 10.1 EER x 0.986/1.009 = 9.9 EER

AGZ Chiller Selection Procedure

Packaged Chiller, Model BS

Selection with Inch-Pound (I-P) units

Table 13 and Table 14 cover the range of leaving evaporator water temperatures and outside ambient temperatures included under ARI Standard 550/590-2003. The tables are based on a 10 degree F (5.5 degree C) temperature drop through the evaporator. Adjustment factors for applications having other than a 10 degree

5 degree C) drop can be found in Table 7. The minimum leaving chilled water temperature

F (5. setpoint without glycol is 40°F (4C). For brine selections, see Table 5 through Table 6 for glycol adjustment factors. Ratings are based on a 0.0001 ft2 x hr x F/Btu fouling factor in the evaporator at sea level operation. For other fouling factors, different Delta-Ts, or altitude correction factors see Table 7. For applications outside the catalog ratings contact your local Daikin sales representative.

Selection example

 20 tons minimum requirement  95°F ambient temperature  48 gpm, 54F to 44°F chilled water  0.0001 evaporator fouling factor

1. From Table 13, an AGZ 020B at the given conditions will produce 21.5 tons with a unit kW and a unit EER of 8.9.

2. Use the following formula to calculate any unknown elements.

3. Determine the evaporator pressure drop. Using Figure 7 on page, enter at 48 gpm and follow up to the AGZ 020B line intersect. Read horizontally to obtain an evaporator pressure drop of 5.9 feet of water.

ote the allowable minimum and maximum flows.

Selection example using ethylene glycol

 20 tons minimum requirement  95°F ambient air temperature  54°F - 44°F chilled water temperature  0.0001 evaporator fouling factor  Protect from freezing down to 0°F

1. From Table 5, select an ethylene glycol concentration of 40% to protect against freezing at 0°F.

2. At 40%

GPM = 1.132, pressure drop = 1.557

3. Select the AGZ 020B from Table 13 and correct with 40% ethylene glycol factors.

Remote Evaporator, Model BM

Inch-Pound (I-P) Units

Since the AGZ-BM units always include a specific remote evaporator, packaged chiller ratings are used. The ratings are based on leaving chilled water temperature and ambient air temperature with correction for the effect of the interconnecting refrigerant piping.

Table 13 and Table 14 cover the range of leaving evaporator water temperatures and outside ambient temperatures included under ARI 550/590-2003. The tables are based on a 10-degree F (5.5degree C) temperature drop through the evaporator. Adjustment factors for applications having other than a 10-degree F (5.5-degree C) drop can be found in Table 7. The minimum leaving chilled water temperature setpoint without glycol is 40°F (4C). For brine selections, see Table 5 or Table 6 for glycol adjustment factors. Ratings are based on a 0.0001 ft2 x hr x F/Btu fouling factor in the evaporator at sea level operation. For other fouling factors, different Delta-Ts, or altitude correction factors see Table

7. For applications outside the catalog ratings, contact your local Daikin sales representative.

The length and configuration of the field installed interconnecting refrigerant piping will affect the system capacity. Derates based on equivalent length of line are given in Table 12.

The steps for selecting an AGZ-BM are as follows:

1. Add 3% to the required cooling capacity (to approximate the effect of the correction factors to be determined) and make a preliminary unit selection from Table 13 and Table 14.

2. Divide the required capacity Table 6, altitude, chilled water Delta T, or fouling factor from Table 7, and refrigerant piping derate from Table 12 as explained in step 3 below.

3. Determ summing the equivalent feet (from table 10) of all the fittings (use a sketch of the piping layout) and adding the sum of these fitting losses to the actual linear feet of tubing. This will equal the total equivalent feet. (To use the equivalent feet table 10, start with the unit suction connection size from table 13 and correct if required.)

4. If the unit rated capacity in the tables is less than the corrected required capacity, redo the selection with the next larger unit. In most cases the line size will be the unit connection size. If the selection is satisfactory, correct the power (if applicable) and determine water pressure drop. Selection example

Application Adjustment Factors

Ethylene and Propylene Glycol Factors

AGZ units can operate with a leaving chilled fluid temperature range of 20°F (-6°C) to 60°F (10°C). A glycol solution is required when leaving chilled fluid temperature is below 40°F (4.6°C). The use of glycol will reduce the performance of the unit depending on concentration.

Altitude Correction Factors

Performance tables are based at sea level. Elevations other than sea level affect the performance of the unit. The decreased air density will reduce condenser capacity consequently reducing the unit's performance. For performance at elevations other than sea level refer to Table 7.

Evaporator Temperature Drop Factors

Performance tables are based on a 10°F (5°C) temperature drop through the evaporator. Adjustment factors for applications with temperature ranges from 6°F to 16°F (3.3°C to 8.9°C) are in Table 3. Temperature drops outside this 6°F to 16°F (3.3°C to 8.9°C) range can affect the control system's capability to maintain acceptable control and are not recommended.

The maximum water temperature that can be circulated through the evaporator in a non-operating mode is 100°F (37.8°C).

As fouling is increased, performance decreases. For performance at other than 0.0001 (0.0176) fouling factor refer to Table 7. Foreign matter in the chilled water system will adversely af the evaporator and could increase the pressure drop and reduce the water flow. Maintain proper water treatment to provide optimum unit operation.

Quiet Operation

Sound levels can be as important as unit cost and efficiency, and must be addressed before the start of any development program. Efforts by Daikin’s Design Engineers to design units that are sensitive to the sound requirements of the market, combined with inherently quiet scroll compressors, have paid off.

Background Information

Sound is a vibration in an elastic medium and is essentially a pressure and particle displacement phenomena. A vibrating body produces compression waves, and as the waves are emitted from the vibrating body, molecules are ultimately compressed. These values are transmitted through gas, liquid, solidanything which is elastic or viscous.

The sound data provided in this section is presented with both sound pressure and sound power levels. Sound power is the total sound energy radiated by a source per unit of time integrated over the surface through which the sound is radiated. Sound power is a calculated quantity and cannot be measured directly like sound pressure. Sound power is not dependent on the surrounding environment or distance from the source, as is sound pressure.

Sound pressure varies with the distance from the source and is dependent on its surroundings. For example, a brick wall located 10 feet from a unit will affect the sound pressure measurements differently than a brick wall at 20 feet. Sound pressure is measured in decibels (dB), which is a dimensionless ratio (on a logarithmic scale) between measured sound pressure and a reference sound pressure level.

Sound Pressure Levels - Full Load

All sound pressure tables give the overall "A" weighted sound pressure levels which are considered typical of what can be measured in a free field with a hand held sound meter, in the absence of any nearby reflective surfaces. The sound pressure levels are measured at 30 feet (10 meters) from the side of the unit at 100% unit load and ARI conditions. 95°F (35°C) ambient air temperature and 50F suction temperature.

Sound Power Levels

Acoustical consultants can require sound power octave band data to perform a detailed acoustical analysis. The tables present sound power levels per ARI Standard 370, “Sound Rating of Large Outdoor Refrigerating and Air Conditioning Equipment”. These standards were developed to establish uniform methods of determining the sound power radiated by large outdoor and indoor equipment. The aforementioned methods are based on providing sound power levels by octave band and the overall ‘A’ weighted value. Measurements are taken over a prescribed area around the unit and the data is mathematically calculated to give the sound power, dB. Sound power can be thought of as basic sound level emanating from the unit without consideration of distance or obstructions.

Sound Reduction due to Distance from the Unit

The distance between a source of sound and the location of the sound measurement plays an important role in minimizing sound problems. The equation below can be used to calculate the sound pressure level at any distance if the sound power is known. Results for typical distances are tabulated in Table 19. Another way of determ dimensionless number that compensates for the type of sound reflection from the source. For example, a unit sitting on a flat roof or ground with no other reflective surfaces or attenuation due to grass, snow, etc., between source and receiver: Q=2.

ining the effect of distance is to work from sound pressure only. “Q”, the directionality factor, is a

distance from the unit if the sound power is known.

Uniform Radiation over ¼ of sphere

Lp=Lw-(20 log r) + (10 log Q) - .5

Lp = sound pressure r = distance from unit in feet

Lw = sound power Q = directionality factor

With Q=1

, Unit suspended in space (theoretical condition), the equation simplifies to:

Lp = Lw – (20)(log r) –0.5

With Q=2

, for a unit sitting on a flat roof or ground with no adjacent vertical wall as a reflective surface, the equation simplifies to: Lp = Lw – (20)(log r) + 2.5

With Q=4

for a unit sitting on a flat roof or ground with one adjacent vertical wall as a reflective surface, the equation simplifies to: Lp = Lw – (20)(log r) + 5.5

The equations are reduced to table form in Table 19 for various distances and the two most usual cases of “Q” type of location.

Unit operation at a lower ambient temperature than 95°F (35C) will also result in lower sound pressure levels. The sound pressure level will decrease 1 dBA for ambient temperatures between 85F and 94°F (29.4C and 34.4C), 2 dBA for ambient temperatures between 75F and 84°F (23.9C and 28.9C), and 3 dBA for ambient temperatures between 65F and 74°F (18.3C and 23.3C).

Optional Acoustic Packages

For sound-critical applications, optional acoustical blankets can be factory-installed on each compressor. They are also available for retrofit field installation.

Electrical Data

Field Wiring

Wiring must comply with all applicable codes and ordinances. Warranty is void if wiring is not in accordance with specifications. Copper wire is required for all power lead terminations at the unit.

ACZ-B and AGZ-B units have single-point power connection. A single field supplied fused disconnect is required or it can be supplied as a factory-mounted option. The control transformer is factory mounted.

ACZ/AGZ-B units are rated to 115F (46C) maximum operating ambient air temperature as standard. There is no high ambient option of vents or fans.

Notes for Electrical Data:

1. Unit wire size ampacity (MCA) is equal to 125% of the largest compressor-motor RLA plus 100% of

RLA of all other loads in the circuit.

2. The control transformer is furnished and no separate 115V power supply is required.

3. For a separate 115V control circuit power supply, use 10 amps for all unit sizes.

4. Recommended power lead wire sizes for 3 conductors per conduit are based on 100% conductor

ampacity in accordance with NEC. Voltage drop has not been included. Therefore, it is recommended that power leads be kept short. All terminal block connections must be made with copper wire.

5. “Recommended Fuse Sizes” are selected at approximately 175% of the largest compressor RLA, plus

100% of the RLA of all other loads in the circuit.

6. “Maximum Fuse or breaker size” is selected at approximately 225% of the largest compressor RLA, plus

100% of all other loads in the circuit.

7. The recommended power lead wire sizes are based on an ambient temperature of 86°F (30°C). Ampacity

correction factors must be applied for other ambient temperatures. Refer to the National Electrical Code Handbook.

8. The unit must be electrically grounded according to national and local electrical codes.

Voltage Limitations:

Within  10 percent of nameplate rating

Important: Voltage unbalance not to exceed 2% with a resultant current unbalance of 6 to 10 times the voltage unbalance per NEMA MG-1, 1998 Standard. This is an important restriction that must be adhered to.

Notes for “Compressor and Condenser Fan Amp Draw”:

1. Compressor RLA values are for wiring sizing purposes only but may not reflect normal operating current

draw at rated capacity.

2. Fan motor FLA values are approximate fan motor amp values at rated voltage.

Notes for “Field Wiring Data”

1. Requires a single disconnect to supply electrical power to the unit. This power supply must either be

fused or use a circuit breaker.

2. All field wiring to unit power block or optional non-fused disconnect switch must be copper.

3. All field wire size values given in table apply to 75°C rated wire per NEC.

Circuit Breakers

The circuit breaker used in the High Short Circuit panel option may have a higher trip rating than the unit Maximum Overload Protection (MOP) value shown on the unit nameplate. The circuit breaker is installed as a service disconnect switch and does not function as branch circuit protection, mainly that the protection device must be installed at the point of origin of the power wiring. The breaker (disconnect switch) is oversized to avoid nuisance trips at high ambient temperature conditions.
