The difference between the working principle of air source heat pump and ordinary

Release Time：2021-07-21

Air source heat pump is an energy-saving device that uses high-level heat to flow heat from low-level heat source air to high-level heat source. It is a form of heat pump. As the name implies, heat pump is like a pump, which can convert low-level heat energy (such as air, heat contained in soil and water) that cannot be directly used into high-level heat energy that can be used, thus saving part of high-level energy (such as coal, gas and oil, electrical energy, etc.).

Working principle:
The heat pump uses the reverse Carnot principle to absorb a large amount of low-temperature air source heat energy in the air with very little electric energy, which is converted into high-temperature heat energy through the compression of the compressor, which is transmitted to the water tank to heat hot water, so it has low energy consumption and high efficiency. Fast speed, good safety, strong environmental protection, and continuous supply of hot water.
The working principle diagram of air source heat pump is a hot water system, which has incomparable advantages. The heat pump hot water unit follows the law of conservation of energy and the second law of thermodynamics. Using the principle of heat pump, it only needs to consume a small part of mechanical work (electric energy). The air source heat pump transfers the heat in low temperature environment (atmosphere or groundwater, etc.) to the water heater in high temperature environment to heat and produce high temperature hot water.
As we all know, the working principle of the air source heat pump is the reverse Carnot cycle principle, that is, the low heat energy in the air is absorbed into the high heat energy that can be used through the work of the compressor, and then exchanged with the water system to provide hot water, heating and other purposes.
The temperature environment of ordinary air source heat pump operation is best above minus 10 degrees, if it is running at minus 10-25 degrees, it may appear:.
The unit cannot defrost: under low temperature environment, it is easy to weaken the defrosting capacity of the air source heat pump unit. Due to the small suction of the unit, the density of the air that can be inhaled is reduced. With the accumulation of time, the thickness of the frost layer is getting higher and higher, resulting in the decrease of the air conversion capacity of the unit, the decrease of the circulation of the refrigerant and the decrease of the overall heating capacity.
Compressor failure: the exhaust temperature rises rapidly, and the working fluid is overheated. When the working fluid is overheated, the thermal conductivity of the working fluid in the condenser decreases sharply. At the same time, the temperature of the lubricating oil rises and the viscosity drops, which affects the compressor. Normal lubrication causes compressor failure.
