Note:
■ Test conditions for nominal cooling capacity: outlet water temperature 7°C; water flow: 0.172m3/(h·kw); outdoor ambient temperature 35°C.
■ Test conditions for nominal heating capacity: outlet water temperature 45°C; water flow: 0.172m3/(h·kW); outdoor dry/web bulb temperature
7°C/6°C.
■ Water resistance at the air conditioner side includes water pressure drop of the unit and the attached Y-shaped filter.
■ Main Pipes of combined units need to be customized and installed on site. The diameter of the pipes must meet design requirements. EK
does not provide the pipes.
■ Modular units can be formed using the 1 - 16 basic modules of same type or of different types as per practical needs. The above table lists
the parameters for common module combinations.
■ For on-site electric wiring, see the name plate or installation menu of the unit.

Decription

?

?? 1. The unit uses environment friendly refrigerant R410A. ? ? ? ? ? ? ? ? ? ? ????? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ???? ? The R410A refrigerant does not cause any ozone depletion.???? ? ? ?????? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?? ???????? ? The heat exchange performance is excellent, improving the COP.????

???????? ? Less refrigerant is used, reducing the green house effect.

2. The unit features an efficient scroll compressor and heat exchanger. Modules of the system are best matched to improve heat exchange efficiency. The unit uses efficient and environment friendly refrigerant R410A, providing a higher COP. Multi-loop compressors are used to provide multiple capacity adjustment gears. This reduces startup current and electric investment. Excellent COP greatly reduces energy consumption and operation cost.

?

3. Before powering on and turning on the unit, you just need to connect the water pipe of each module to the main water pipe. A special access door is provided so that any inter parts of the unit can be conveniently serviced.

4? ? ? ? A low-sound fan generates little operation sound and vibration.???????

??????? ? R410A scroll compressor generates little operation sound and vibration.

??????? ? A flexible installation base further reduces operation vibration.????

??????? ? Air outlet pipes of the compressor are optimized to reduce vibration passed to the unit.
