SAFETY SUMMARY

% DANGER:

– Use refrigerant R407C in the refrigerant cycle. Do not

charge oxygen, acetylene or other flammable and poisonous gases into the refrigerant cycle when performing a leakage test or an air-tight test. These types of gases are extremely dangerous and can cause an explosion. It is recommended that compressed air, nitrogen or refrigerant be used for these types of tests.

– Do not pour water into the indoor unit, outdoor unit or

CH unit. These products are equipped with electrical parts. If poured, it will cause a serious electrical shock.

– Do not touch or adjust safety devices inside the indoor

or outdoor units. If these devices are touched or readjusted, it may cause a serious accident.

– Do not open the service cover or access panel for the

indoor or outdoor units without turning OFF the main power supply.

– Refrigerant leakage can cause difficulty with breathing

due to insufficient air. Turn OFF the main switch, put out fire at once and contact your service contractor, if refrigerant leakage occurs.

– The installer and system specialist shall secure safety

against leakage according to local regulations or standards.

$ WARNING:

– Do not use any sprays such as insecticide, lacquer,

hair spray or other flammable gases within approximately one (1) meter from the system.

– If circuit breaker or fuse is often activated, stop the

system and contact your service contractor.

– Do not perform installation work, refrigerant piping

work, drain piping and electrical wiring connection without referring to our installation manual.

– Check that the ground wire is securely connected.

Connect a fuse of specified capacity. Do not put any foreign material on the unit or inside the unit. Make sure that the outdoor unit is not covered with snow or ice, before operation.

& CAUTION:

– Do not install the indoor unit, outdoor unit, CH unit,

remote control switch and cable within approximately 3 meters from strong electromagnetic wave radiators such as medical equipment.

– Supply electrical power to the system to energize the

oil heater for 12 hours before start-up after a long shutdown.

? NOTE:

– It is recommended that the room be ventilated every 3

to 4 hours.

– The heating capacity of the heat pump unit declines

according to the outdoor air temperature. Therefore, it is recommended that auxiliary heating equipment be used in the field when the unit is installed in a low temperature region.

SYSTEM DESCRIPTION

High economical efficiency operation

HITACHI use the high technology to achieve the high operation efficiency. The applications of the following technologies provide HITACHI to achieve results like the great power saving due to heat recovery system. During Simultaneous cooling and heating operation, only for FXG(1), energy is saved by the heat exchange between indoor units.

These technologies are:

Supercooling Circuit

Performance improved by high-efficiency plate type of heat exchanger.

DC Fan Motor with Outstanding Efficiency

The DC fan motor greatly improves efficiency compared with conventional products having an AC motor. Also, air blasts are reduced by controlling the rotation speed of the fan.

n DC Compressor Using Neodymium Magnet

A DC compressor is used for all models, thus greatly increasing efficiency in all operating areas. In particular, performance at a low speed, which affects the annual running cost, has greatly improved. Moreover, the peculiar electromagnetic noise to DC compressors has been cut by optimizing the rotor shape of the compressor.

n New Heat Exchanger

The new smaller flow resistance heat exchanger using new aluminum fins and pressure loss in pipe decreases with optimized path alignment provides power saving. Also, it has achieved a lower sound operation due to lower fan revolution.

SYSTEM DESCRIPTION

n Top Class Silence Operation

HITACHI use the high technology to achieve the Lowest sound possible

These Technologies are:

§ PWM ( Pulse With Modulation) Control Fan motor control by PWM has realized low electromagnetic sounds remarkably.

§ Low Operation Sound Resulting from New Fan Shape and Propeller Fan Material The combination of most appropriate fan shape for smooth air flow and a new material of Mica polypropylene has resulted in a low operation sound which was almost impractical in previous units.

§ Low Sound Operation by Low Noise Fan Motor Aluminum die-casting was used for assembled fan motor and low sound operation has been achieved. And due to a non resonance suspension structure, the vibration sound has been minimized.

Lower Sound Operation during Night Time

By improved at around of cabinet structure and fan shape, and by the adoption of new material and inverter, operation sound has been reduced.

Precise Control with the wide Range Inverter

The compressor speed for Set-Free series outdoor unit is controlled within a wide range of from 30Hz to 115Hz. Therefore, smooth operation is available without frequently using the ON/OFF control. This new wide range capacity control can meet not only the needs of a wide space but also a small space such as guest rooms and management rooms. Defrosting operation can be quickly performed because of a high compressor speed of 70~75Hz.

Electronic Control

The capacity of the Outdoor unit is continuously controlled by the inverter from 3.3% to 130%. This wide working range has been obtained by the improvement of shaft strength and high pressure oil circulation in the scroll compressor.

Therefore, an air conditioning system where heat load is greatly changed through the day is easily catered for. Also, the capacity of indoor unit is controlled by detecting the inlet and set room temperatures using an inverter driven compressor. Therefore even a small room can be air conditioned without unwanted ON/OFF operation, resulting in comfortable air conditioning.

CAPACITIES AND SELECTION DATA

4.1. SYSTEM SELECTION PROCEDURE

The following system procedure is giving a sample regarding unit selection system, indicating how to use all parameters showed in this chapter.

4.1.1. SELECTION UNIT FEATURES

Considering the building distribution, the possible indoor unit position and the available air flow distribution, select the unit features that is giving the best efficiency and comfort to each room. Decide the Outdoor Unit position getting easy service maintenance and easy refrigerant pipe installation.

Use the information showed in the following subchapters:

§ For Operation Space possibilities: Subchapter 4.2 Operation Space.

§ For Air Flow distribution: Subchapter 4.10 Temperature Distribution Diagrams.

§ For Noise Characteristics: Subchapter 4.11 Sound Data

§ For Outdoor Unit position: Subchapter 4.2.8 Outdoor Unit

§ For CH-Box position: Chapter 12.9.2

§ Piping length and lift range: Chapter 13

If duct type unit is selected, the fan performance for duct calculation should be considered, as Subchapter 4.9 shows. The units are designed with three possible static pressure ranges in order to adapt it to all installation necessities.

As indicated in chapter 1, the Set-Free system enable the outdoor unit to be up to 30% smaller capacity when compared with the current split Air Conditioning systems. The diagram shows a typical building with a morning peak heat load on the east zone equivalent to a 6HP unit. In the afternoon a peak occurs on the west zone equivalent to a 7HP unit.

Therefore, a conventional system would require total installed plant of 6HP + 7HP = 13HP. The maximum simultaneous load on the whole building occurs at noon and is equal to 10HP of unit capacity. A Set-Free System of 10HP can therefore be selected, and this capacity can be directed either to the east or west zone as dictated by the system controls. Saving in installed plant = (6.5-5) / 6.5 x 100 = 23%!!!

Example of Air Conditioning for Building

Therefore, the maximum indoor unit capacity combined with outdoor unit should be carefully considered for correct indoor unit distribution at each building

For three pipes systems, FXG, the units distribution is more flexible, because of each indoor unit can operate at different mode, cooling or heating. At the same time, is possible to combine several indoor units with the same CH-Box when all the space need the same operation mode, or all indoor units will be used in the same room, in order to get better Air flow distribution. Do not forget to consider that option during installation design.

4.1.2. SELECTION GUIDE

The following example is giving the method for indoor and outdoor units selection of Set-Free system. The same system can be used for FSG, FSG1, FXG and FXG1.

* Step 1: Determine the system requirements

Calculate the cooling capacity and heating capacity of each indoor unit according to the following conditions:

Total Load for each room

Nominal Heating Capacity

4.2 6.5 9.0 19.7 17.8

* Step 3: Read Selected Unit Performance

Unit performance should be calculated considering the following correction factors:

Correction Factor According to Piping Length (Subchapter 4.6):

§ Cooling = 0.85

§ Heating = 0.94

Correction Factor for Defrosting Operation (Subchapter 4.8) = 0.89

Correction Factor According to Temperature Condition:

§ Cooling (Subchapter 4.4) = 1.03

§ Heating (Subchapter 4.5) = 0.94

Step 3a: Outdoor Unit Performance Capacity

Cooling Capacity = 14.8 x 0.85 x 1.03 = 12.96 kW

Heating Capacity = 17.8 x 0.94 x 0.94 x 0.89 = 14.00 kW

Page 76

CAPACITIES AND SELECTION DATA

Step 3b: Indoor Unit Performance Capacity

<RPI-1.5> (adjusted at 1.3)

Cooling Capacity = 12.96 x (3.8 / 17.6) = 2.80 kW

Heating Capacity = 14.00 x (4.2 / 19.7) = 2.98 kW
