Working theory for heat pump:
Air source Heat pump water heater is a new power-saving technology
product, which makes use of the cycle principle, absorbs heat
energy from the air, and convert it to the water. The equipment
is composed of compressor, evaporator, expansion valve and motor.
Through compressor working, change the refrigerant status physically,
gas-liquid-gas, thus repeat the same cycle, absorb and give
out the heat, makes the water become hot gradually. |

The COP coefficient increases greatly
with the environments temperature rising from 5℃to 35℃ for the
same consumptive power, although the heat pump working temperature
ranges from minus 15℃ to 40℃.
