FEATURE

Achieves high system efficiency under cooling operation, with the use of expansion valve same as traditional air conditioners.

Under heating operation, the heat pump system draws up heat from outside air, and provides heat to the cabin. A unique valve control system controls dehumidifying heating, preventing windows to be fogged up, and maintain heating. Even when the outside temperature is very low, able to keep sufficient heating with the use of high performance water heater.

EXV(Electric Expansion Valve)

Function: By inputting a pulse signal, the high temperature and high pressure liquid refrigerant is decompressed and expanded. Feature: Achieves both high reliability and low cost to adapt the step motor without an electronic circuit
