solar water heater with heat pump

SAVE the energy. COP:4-4.5 heat pump solar water heater with free solar energy

solar water heater with heat pump

I. Feature:

1. Energy saving;

2.Cost little electrity for hot water uage when the cold couldy winter days;

II. Working Principles;

In the sunny days, the solar water heater can heat the cold water into  40-50 degree, but in the couldy rainy days, the water can not reach to your ideal temp.require, then the air source heat pump  start to work , which aotumatically start to heat the water into max.65 degree.

Air source heat  pump Compressor gets the low tempratrue 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 flowmeter 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 refrigeran, then is absorbed by compressor, recycling to produce the hot water.
