SOLAR WATER HEATER
HEAT PUMP
 
  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 5íŠto 35íŠ for the same consumptive power, although the heat pump working temperature ranges from minus 15íŠ to 40íŠ.
