Air energy water heaters, with their significant energy-saving properties, are ideal for modern home hot water supply. It uses the heat in the ubiquitous air to realize the heat transfer from low-temperature heat sources to high-temperature heat sources through heat pump technology.

The heating process of air energy water heaters mainly goes through the following key steps:

1. Compression link: At this stage, the compressor compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas. During this transition, the system needs to consume a certain amount of electrical energy to drive the compressor, which increases the thermal energy of the refrigerant from low grade to high grade.

2. Heat exchange process: Subsequently, the high-temperature and high-pressure refrigerant gas enters the condenser and exchanges heat from air or water. In this process, the refrigerant gas condenses into a liquid and releases a large amount of heat, causing the water temperature to rise significantly. At the same time, the thermal energy state of the refrigerant is reduced from high grade to low grade.

3. Expansion link:The condensed refrigerant liquid is depressurized by an expansion valve and transformed into a gas with low temperature and pressure. During this process, the refrigerant undergoes the separation of the gas from the liquid, where the gas partially continues to cool and liquefy in the condenser.

4. Evaporation link: The refrigerant gas at low temperature and low pressure enters the evaporator and is exchanged with air or water again. The refrigerant absorbs heat during evaporation, changing from a gaseous state to a vapor state while reducing the water temperature. In this process, the fan of the heat pump unit drives the air to flow through the fins of the unit for heat exchange, and the air blown out is in a cold air state.

5. Cycle process:Through the cycle of the above four links, the air energy water heater can continuously transfer the heat in the air and water to the water, so as to continuously produce hot water.

Air energy water heaters are mainly composed of evaporators, compressors, condensers and storage tanks, and their working principles are based on thermodynamic principles and refrigeration cycle principles. Through the realization of the evaporator's endothermic absorption process, refrigeration principle, and compressor circulation principle, air energy water heaters can efficiently heat hot water while having the advantages of environmental protection and economy.
