Description
Working Principle of an Air Source Heat Pump
Air source heat pump technology operates on the principle of the reverse Carnot cycle, delivering an energy-efficient and environmentally friendly heating solution. The system extracts low-temperature heat from natural energy sources or air. It efficiently collects and integrates this heat, converting it into a high-temperature heat source. This high-temperature heat is then used for space heating or hot water supply. The system achieves a very high heat collection efficiency throughout its operation.
Heating Process of an Air Source Heat Pump
An air energy heat pump transfers energy in several steps:
- In the evaporator, the medium absorbs a large amount of free energy (Q1) from the air.
- The compressor then compresses the medium into high-temperature, high-pressure gas, doing work (Q2).
- Through the heat exchanger, the medium exchanges heat energy (Q3) to provide hot water or heating.
According to the law of conservation of energy, the heat energy (Q3) is equal to the sum of electric energy (Q2) and air energy (Q1).
Main Components of an Air Source Heat Pump
Advantages of Air Source Heat Pumps：
a. Air source heat pumps absorb free energy from the air to heat. This method boosts efficiency and saves energy. The system cuts electricity use by 75% compared to electric heating.
b. Air source heat pumps avoid combustion and exhaust emissions. They eliminate fire and explosion risks linked to boilers.
c. Air source heat pumps work in any weather with air. Unlike solar heating, they are unaffected by rain.
d. The machine operates automatically without special maintenance. This feature reduces manual upkeep costs compared to traditional heating.
