Compressor
The dependable flexible
compressor, with optimized
R410a system, can achieve high
water temperature up to 60DegC,
while ensures long life of the
compressor.
4-Way valve
The reliable 4 way valve can
avoid gas mixing, and ensure
stable defrosting.
Condenser
The Tube in shell heat exchanger as
condenser, with bigger heat
exchanging area and higher
efficiency.
Thermal expansion valve
The 2 way thermostatic expansion
valve ensures high efficiency when
heating, moreover, ensures high
efficiency when defrosting.
Evaporator
The hydrophilic fin-tube heat
exchanger has big heat exchanging
area and rational fin distance, thus
significantly improves heating and
defrosting efficiency.
Fan
The exterior motor fan, with 5 fan
blades, is strictly balanced. The 5
fan blades run slower, and make
sure high air volume, thus largely
brings down the noise.
