Air energy heat pump has now become a relatively popular new energy energy saving and environmental protection equipment. It uses the heat in the air of the phone to heat the water temperature through the work of the unit. The temperature of the hot water produced by an ordinary air source heat pump is about 55 degrees Celsius. It can meet our daily needs. The need for hot water can also provide us with heating needs.

As we all know, there is heat in the air, and this heat is generated by solar radiation. Due to the influence of seasons, the temperature varies greatly, which will also affect the working efficiency of the air energy water heater. Generally speaking, when used in an area with an average temperature of 20 degrees Celsius, consuming one kilowatt of electricity will generate 3 to 4KW of heat, which is more energy-efficient than traditional electric water heaters and gas water heaters. So, how does an air-to-air heat pump use the heat in the air to heat cold water Let's take a look at an air-to-energy heat pump.

The air-energy heat pump consists of an outdoor unit and an insulated water tank. The outdoor unit is called an air energy heat pump unit. Air-energy heat pump units are generally composed of expansion valves, compressors, evaporators, condensers, etc., and some main components. In a nutshell, how it works is that the low-temperature refrigerant in the compressor system continuously absorbs the low-grade heat from the outdoor air and brings it back to the compressor to be upgraded to useable high-grade heat to heat the cold water. . The heating principle of the air energy heat pump is basically similar to the working principle of the air conditioner, but the basic configuration and function of the product are different.

The compressor in the unit converts the low temperature and low pressure gaseous refrigerant into high pressure and high temperature gas. The heat that the operating power of the compressor can convert into is Q1. The high temperature and high pressure gaseous refrigerant exchanges heat with water. High-pressure refrigerant cools at room temperature and condenses into a liquid state. During this process, the refrigerant releases heat to heat the water, which becomes hot. The heat absorbed by the water is Q3, the high pressure liquid refrigerant is reduced through the expansion valve, the pressure drops and returns to a lower temperature than the outside world, which has the ability to absorb heat and evaporate. The liquid refrigerant in the low pressure and low temperature state passes through the evaporator, that is, the air heat exchanger, absorbs the heat in the air and evaporates by itself, changing from liquid to gas. The heat absorbed by the refrigerant from the air is Q2. The refrigerant that absorbs heat becomes a low-temperature, low-pressure gas that is sucked in by the compressor for compression. In this way, the reciprocating cycle continuously absorbs heat from the air, while the water-side heat exchanger releases heat to produce hot water. The cycle process is completed by the air energy heat pump (host) unit. As a system equipment that effectively collects heat and transfers heat, the air energy heat pump can convert the power consumed by the compressor into 3-5 times the heat energy (i.e. Q1 + Q2 = Q3).
