With people’s increasing awareness of energy conservation, energy-saving products have become popular among consumers. Air energy water heaters, also known as air energy heat pumps are an example. With the strong promotion of “coal to electricity” in China, more and more users are using air energy water heaters( air energy heat pumps heating). Many people know about using air energy heat pumps for heating, but they are not very familiar with the air energy heat pump refrigeration (air energy heat pump cool) function. So, how air energy heat pumps cool down will be explained in detail by Bluete’s engineers below.
The principle of air energy heat pump refrigeration
Air source heat pump is a type of heat pump that compresses the recovered low-pressure refrigerant into high-temperature and high-pressure gas through a heat pump unit. The high-temperature and high-pressure refrigerant gas flows through a copper pipe wrapped around the outside of the water tank, and the heat is transmitted to the water tank through the copper pipe. At this time, it can provide high-temperature hot water required for heating or underfloor heating. Subsequently, the cooled refrigerant becomes liquid under the continuous pressure, passes through the expansion valve, and enters the evaporator. Due to the sudden decrease in pressure in the evaporator, the liquid refrigerant quickly evaporates into a gaseous state and absorbs a large amount of heat. Under the action of the fan, a large amount of air flows through the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator. The temperature of the air rapidly decreases, and it becomes cold air and is discharged into the fan coil unit to provide refrigeration services. Subsequently, the refrigerant absorbed by the evaporator flows back to the compressor and enters the next cycle of operation.
Simply put, when the air conditioner cools down in summer, it operates under refrigeration conditions. The high-pressure steam discharged by the compressor enters the condenser through a directional valve, and the refrigerant steam is condensed into a liquid. It enters the evaporator through a throttling device and absorbs heat to cool the indoor air. The evaporated refrigerant steam is sucked in by the compressor after passing through the directional valve, thus achieving a refrigeration cycle.
The advantages of air energy heat pump refrigeration:
- Air energy heat pumps are energy-saving, low consumption, and have high refrigeration efficiency.
- Air energy heat pumps are clean and pollution-free, which is beneficial for environmental protection.
- Efficient dehumidification, with a maximum dehumidification capacity of 6-8 kilograms per day for 24 hours. The effect is significant in rainy and cloudy weather;
- Long service life: The air energy heat pump is selected from world-renowned spare parts, with five layers of rust prevention technology. The shell is made of corrosion-resistant and ultra-thick coated steel plate or stainless steel plate, ensuring stable equipment performance and a service life of up to fifteen years.
The above is an introduction to air energy heat pump refrigeration. Bluete’s engineers pointed out that if users want the air energy heat pump to have a cooling effect, they need to choose a dual-use host that has both cooling and heating effects. Simply put, air energy heat pumps are similar to air conditioners, but they have better performance and higher comfort, without causing indoor dust accumulation.
