When understanding the maintenance of heat pump air conditioning, let's discuss its principle first. Because only by understanding its principle can it be fundamentally maintained. For this kind of air conditioner, its structure is basically the same as that of single cooling air conditioner. It mainly uses the principle of air conditioning and refrigeration in summer. This is the summer air conditioning generally adopts indoor refrigeration and outdoor heat dissipation. But when heating is needed in autumn and winter, it is the opposite of summer. That is, indoor heating and outdoor cooling, so as to achieve the purpose of heating. Generally, due to long-term application, the opposite problem may appear here. It's still a question of temperature control. In this case, attention should be paid to whether the corresponding control system is in good condition during maintenance.

From the advantages, this kind of air conditioner is more efficient, but the disadvantage is that the applicable temperature range is small, and generally it will stop working below MINUS 5 degrees. Let's talk about its working principle and the points that should be paid attention to during maintenance.
Shallow geothermal energy is that under the radiation of the sun, the earth becomes a giant "reservoir" of solar energy, and a large amount of clean renewable energy is stored in shallow water and rock mass of the earth's crust, which is called shallow geothermal energy, or simply referred to as ground source.

Heat pump technology is an energy-saving technology invented by modern science. A certain amount of electric energy is input into the heat pump unit to drive the compressor to do work, so that the working fluids in the unit (such as R22, R 134a) repeatedly undergo the physical phase change process of evaporation and condensation, and heat exchange and transfer in space are realized. In the maintenance process of heat pump air conditioning, we should always pay attention to the changes between them.

In addition, the ground source heat pump central air-conditioning system is a heating and air-conditioning system which takes rock, ground water or surface water as low-temperature heat sources, and consists of a water source heat pump unit, a geothermal energy exchange system and an in-building system. Its working principle is: in winter, the heat pump unit absorbs heat from the ground source (shallow water or rock and soil) to heat the building; In summer, the heat pump unit absorbs heat from the room and transfers it to the ground source to realize the air conditioning and refrigeration of the building. According to the different forms of geothermal exchange system, ground source heat pump system can be divided into groundwater ground source heat pump system, surface water ground source heat pump system and ground source heat pump system.

As we said above, we should pay attention to the maintenance of heat pump air conditioning. In fact, as we said, its principle and maintenance are positively related. It is impossible to carry out maintenance without understanding the principle. This will only get worse.
