separator separator
In cooling, the low-temperature and low-pressure refrigerant gas from each indoor heat exchanger will be merged and inhaled by the
compressor and then become high-temperature and high-pressure gas, which will later be discharged into outdoor heat exchangers. By
with indoor air, refrigerant wil become low-temperature and low-pressure gas again and repeat the circulation so as to realize the cooling
effect. In heating, 4-way valve will be energized to make refrigerant circulate in a reverse direction of cooling. Refrigerant will release heat in
indoor heat exchangers (electric heating elements will also work under certain circumstance and release heat) and absorb heat in outdoor
heat exchangers circularly so as to realize the heating effect.
