Compressor capacity control is achieved through the optimum balance of three individually rated compressors. This approach is extremely efficient as it provides a wide range of refrigerant flow High rate options. Furthermore, 1 by controlling the amount of gas pumped by each 1 2 2 compressor, the system can accurately adjust refrigerant flow rates.

Power balance control technology achieves high operational efficiencies by detecting low pressure (evaporating temperature) during cooling and high pressure (condensing temperature) during heating and precisely controls the optimum refrigerant condition via refrigerant flow rate (capacity). Waste through excessive refrigerant flow is eliminated as is insufficient capacity due to insufficient refrigerant flow rate.

As our VRF system is not based on inverter technology to control refrigerant flow rate harmonic emissions are almost zero. As a result, it will not interfere with electronic equipment found in the office, factory or power distribution facilities, making it the ideal air conditioning solution for hospitals where harmonic emissions are strictly controlled.

Comfortable Operation Heat Recovery operation Heat Recovery operation is a cooling/heating free operation system, cooling and heating can be performed simultaneously in the same refrigerant system according to user needs. At the moment, The Heat Recovery operation is an extremely superior type that provides a still greater energy saving effect by moving heat between indoor units that are performing the cooling and heating operations. This is by having the compressors act like a pump.

Oil Recovery operation After a fixed period of time the oil recovery operation automatically returns accumulated oil found in the refrigerant circuit and indoor units.

Surroundings Conscious No Harmonic Disturbances As our VRF system is not based on inverter technology to control refrigerant flow rate harmonic emissions are almost zero. As a result, it will not interfere with electronic equipment found in the office, factory or power distribution facilities, making it the ideal air conditioning solution for hospitals where harmonic emissions are strictly controlled.

VRF differs from traditional ventilation and chiller systems being an economical multi air conditioning system that has the ability to exactly match air conditioning to the needs of the space. Whether operating continuously as required within commercial buildings and public facilities or with large load variations for hotels, etc the VRF maintains optimum operation for that building. That means optimum comfort for the occupants at minimum energy expenditure.

INDOOR UNIT

The VRF system offers an infinitely variable choice of indoor and outdoor units: 12 types and 45 models of indoor units together with a choice of 9 outdoor units. Plus 2-pipe (heat pump, cooling only) and 3-pipe (heat recovery) systems are available providing inbuilt reliability. VRF offers flexible and quick air conditioning design solutions supported by low running and maintenance costs, particularly when compared to conventional systems.

Design Flexibility Shorten the design time Compared to conventional building air conditioning systems, VRF system design is fast thanks to the simplicity of the outdoor unit, refrigerant piping and data transmission - and the VRF can control up to 100 outdoor units and 400 indoor units. Refrigerant piping between outdoor and indoor units can extend up to 100m in length with a height difference of 50m, making 15-storey buildings easy to accommodate. So, system design is uncomplicated and fast.

Long piping for high-rise buildings Vertical lift between outdoor unit and indoor units : 50m maximum. When outdoor unit is located above indoor unit. When outdoor unit is located below the indoor unit the height difference is 40m maximum. Vertical lift between indoor unit and indoor units : 15m maximum. Actual pipe length : 100m maximum. Equivalent pipe length : 120m maximum. Total pipe length : 200m maximum.

Flexible Control System Features of control system 1. Reduced wiring as all system equipment accommodated on a single transmission line (non-polar 2-conductor). 2. Total wiring length (total length of transmission line) can be extended up to 2000m (by using signal amplifier units). 3. Maximum of 400 indoor units can be connected. 4. Indoor units can be controlled by wired, simple, wireless, group, central remote controller or PC controller. 5. Central control of single split type models (with exceptions) or big multi type air conditioners is possible from a central remote controller or PC controller. 6. Model combinations are dictated by the building s needs and not the system. 7. The 'simple' remote controller is ideal for installations such as hotel guest rooms.

Slim cassette, designed for limited ceiling space

1. Individual operation of the indoor units ensures that the failure of one does not affect the whole system. 2. Maintenance efficiencies are raised through the connection of a PC anywhere on the data transmission line. 3. Error codes can be clearly displayed on the wired remote controller, simple remote controller, group remote controller, central remote controller or PC controller.

Functions Central building monitoring and control

. Detailed settings can be programmed for each whole building/group/remote controller group or individual indoor unit. . The PC and central remote controller can be used together, allowing system control from two or more locations if required. Central control The 6 functions of the standard controller can be locked from the PC: all functions, timer mode, operating mode, temperature setting, filter reset, on/off. All functions can be controlled via the PC Controller only.

Auto mode (Priority-mode changer) Auto mode function automatically switches between cooling and heating modes based on the temperatures set and the room temperature detected by the master indoor unit. Other operating indoor units can be operated in the same operating mode as the master indoor unit.

Operation Control

User-friendly Operation . Runs under Windows 2000 and Windows XP Professional / Home so is as easy to use as a standard PC. . Operational status can be colour-coded for instant recognition: On/green, Off/red, test/orange, error/flashing. . Operational status can be displayed to user's preference. Linking with external control equipment is possible.

Prevents wireless remote controller interference

Simple external appearance by auto shut flap

Diverse air conditioning control systems linked with various equipment inside the building can be built by using the external I/O port.

The signal cord of the wireless remote controller can be switched and prevents erroneous operation by interference between adjacent indoor units.
