How Does Heat Pump Work

how does heat pump work
The heat pump is an energy moving device.

  • The refrigerant absorbs the free air source energy Q3 from the air by the evaporator.

  • The compressor compresses the refrigerant into high temperature and pressure refrigerant via electric energy Q1.

  • The heat energy Q4 transmits to water in the heat exchanger.

  • According to the law of conservation of energy, heat energy Q4 = air energy Q3 + electric energy Q1.

Heat Pump Advantages

heat pump advantages
Safely heat pump advantages
Energy Saving Up to 80%
Adopt air source heat pump technology, not use hidden troubles created by electric heating and combustible gas for heating, separate water and electrics, safety is the greatest wealth for our life. Air source heat pump heats by absorbing the free energy surrounding air, without any waste emission, high efficiency and energy saving up to 80% compared with the traditional electric heating mode.
heat pump advantages
Comfort heat pump advantages
Environmental Protection
24 hour unlimited central hot water system and floor radiant heating more comfortable for human body to supply a high quality life.

Heat comes from air for free of charge, no exhaust gas produced, use air source heat pump water heater and reduce CO2 emission and save the liquid gas and electricity source.

Protecting ecological sustainable development heat pump technology.
