4.5 Components
Compressor
The depe ndable high efficiency
compre ssor, with op timized R410A
system , can achieve high wa ter
temper ature up to 60 degree s Celsius;
while en sures long life of the compressor.
4-Way Valve
The reliable 4 way valve ca n
avoid gas mixing, and ens ure
stable defrosting.
Condenser
The Tube-in-shell h eat exchanger as
condenser, with big ger heat
exchanging area and hig her
efficiency.
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
defrosting efficien cy.
ABS Plastic Fan
The exterior motor fan, w ith multiple fa n
blades, is strictly bal anced. The mult iple
fan blades run slower, and make sure
high air volume, thus lar gely brings dow n
the noise.
