Indoor unit heat exchanger (For R410A and R134a)
The indoor unit has three heat exchangers:
-
R410A-R134a plate heat exchanger
-
R410A-H2O plate heat exchanger
-
R134a-H2O plate heat exchanger
Highly efficiency plate heat exchanger
The use of a plate heat exchanger type allows getting high performance due to the following advantages:
• High heat transfer surface coefficient, leading to very high values of the heat transfer overall coefficient.
• High flow turbulence in the fluids, achieving turbulent regimes for low Reynolds numbers. This high turbulence allows
lower circulating speeds on the fluids.
• Lower heat losses, since only the edges of the plates are exposed to the outside environment and additionally to
having small thicknesses, it can be readily isolated.
Water pump
Low power consumption
The air to water heat pump incorporates a water pump to circulate the water flow into the system.
This pump is classified as low power consumption, resulting in a higher unit performance.
