[0025] At present, traditional heating equipment can only heat but not cool, which wastes electricity and energy, and brings a lot of inconvenience to users.

[0039] The air energy split unit of the present application is easy to install and low in cost; the outdoor heating unit 1 in winter will never freeze during a power outage, and compared with the operating costs, it saves 50% energy than a gas wall-mounted boiler and 70% energy than an electric heating furnace.

[0040] The split air source heat pump adopts full DC frequency conversion technology, low noise, ultra-low temperature operation, high efficiency and energy saving, less after-sales service and long service life

[0041] To further optimize the solution, in the present application, the fan 4 , the surface cooler 5 , the compressor 6 and the four-way valve 7 can be provided in two groups respectively, all of which are installed in the external chassis 3 .

[0042] The principles of heating, hot water making and cooling of the air energy split unit in this application are as follows:

[0043] 1. The principle of air energy split unit heating:

[0044] When heating in winter, the first thing to do is to adjust the working position of the four-way valve 7. By changing the working position, the high-pressure refrigerant vapor discharged from the compressor 6 will flow into the indoor heat exchange high-efficiency tank 11 after passing through the four-way valve 7. The latent heat released when the refrigerant vapor condenses will heat the indoor heating equipment to achieve the purpose of indoor heating. Then, the liquid refrigerant condensed from the heat exchange high-efficiency tank 11 will flow back through the throttling device and enter the surface cooler 5, absorbing external heat and evaporating. The evaporated vapor will be sucked into the compressor 6 after passing through the four-way valve 7, completing the heating cycle.

[0045] 2. The principle of air energy split refrigeration:

[0046] When cooling down in summer, it operates according to the refrigeration condition. The high-pressure steam discharged from the compressor 6 enters the surface cooler 5 through the four-way valve 7. The refrigerant vapor is condensed into liquid and enters the high-efficiency tank 11 through the throttling device. It absorbs heat in the high-efficiency tank 11 to cool the indoor air. The evaporated refrigerant vapor is sucked into the compressor 6 after passing through the four-way valve 7. This cycle is repeated to realize the refrigeration cycle.

In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0048] In the description of this article, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
