Air source Multifunctional Juteng Heat Pump trinity for heating, cooling and free hot water with High COP, EER
Working Principle:
Compressor gets the low temperature and low pressure air refrigerant from evaporator,
then turn it into high temperature and high pressure air,
this air gets into the condenser to exchange the heat with water,
then the condensed air become low temperature fluid and release lots of heat energy.
Water gets this heat energy and become hotter and hotter.
This high pressure and low temperature fluid become low pressure by the primary flow meter device.
This low pressure and low temperature fluid, gets into the evaporator, Under the function of rotation fan, heat energy from air is absorbed by the fluid and becomes low pressure refrigerant,
then is absorbed by compressor, recycling to produce the hot water.
