Condenser
The Tube in shell heat exchanger as

Thermal expansion valve
The 2 way thermostatic ex pansion
valve ensures high effi ciency when

Evaporator
The hydrophilic fin-t ube heat
exchanger has big heat ex changing
area and rational fin dis tance, thus
significantly impro ves heating and

Fan
The exterior motor fan, w ith 5 fan
blades, is strictly bal anced. The 5
fan blades run slower, and make
