The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
As shown in fig. 1, a conventional air conditioner system includes an air conditioning refrigerant main system;
the air-conditioning refrigerant main system comprises an indoor unit 3 and an outdoor unit 4;
the indoor unit 3 and the outdoor unit 4 are communicated with each other through a refrigerant pipeline 11;
a refrigerant for performing heat exchange circulation between the indoor unit 3 and the outdoor unit 4 flows through the refrigerant pipeline 11;
the indoor unit 3 and the outdoor unit 4 are respectively provided with a heat exchange assembly, and the heat exchange assembly is an indoor heat exchanger.
The heat exchange component is a heat exchanger and can be used as a condenser and an evaporator.
In practical applications, the heat exchange assembly can be divided into an indoor heat exchanger and an outdoor heat exchanger for completing the heat exchange of the air flow.
When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
Fan components are respectively arranged in the indoor unit 3 and the outdoor unit 4;
the fan assembly is used as a driving unit of the air flow and used for driving indoor air to flow and circulate, and the heat exchange assembly is combined to complete the functions of heat exchange and air exchange of the indoor space of the indoor unit 3.
The air conditioner system further includes a compressor 1, a main expansion valve 5, a gas-liquid separator 2, and a four-way valve 6.
The compressor 1 is used for driving the refrigerant in the refrigerant pipeline 11 to flow, and the gas-liquid separator 2 is used for separating the gas refrigerant and the liquid refrigerant in the refrigerant pipeline 11.
The compressor 1 compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas, the discharged refrigerant gas flows into a condenser, the condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through a condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant, the evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 1, the evaporator can achieve a refrigerating effect by heat exchange with a material to be cooled using latent heat of evaporation of the refrigerant, and the air conditioner can adjust the temperature of an indoor space throughout the cycle.
The operation of the air conditioner system will be explained by taking as an example a process of cooling the indoor unit 3 in which the indoor heat exchanger of the indoor unit 3 serves as an evaporator and the outdoor heat exchanger of the outdoor unit 4 serves as a condenser, which involves compressing, condensing, expanding and evaporating, and supplying a refrigerant (i.e., refrigerant) to the air that has been conditioned and heat-exchanged.
After the whole air conditioner system is electrified, low-pressure steam of a refrigerant in the refrigeration system is sucked by the compressor 1 and compressed into high-pressure steam and then discharged to the condenser, and meanwhile outdoor air sucked by the fan assembly flows through the condenser to take away heat emitted by the refrigerant, so that the high-pressure refrigerant steam is condensed into high-pressure liquid. High-pressure liquid is sprayed into the evaporator after passing through the filter and the throttling mechanism, and is evaporated under corresponding low pressure to absorb surrounding heat, meanwhile, the fan assembly enables air to continuously enter fins of the evaporator for heat exchange, and the air which is cooled after heat release is sent to the indoor. Thus, the indoor air continuously circulates and flows to achieve the purposes of refrigerating and reducing the temperature. The refrigerant flowing out of the evaporator is changed into low-temperature and low-pressure gas again by taking away heat (absorbing heat) in the air, and is sucked into the compressor 1 again, and the cycle is repeated.
The heating process of the air conditioner system is simply that the refrigeration process is reversed through the four-way valve 6, the basic principle is the same as the refrigeration principle, and the details are not repeated here.

when the indoor unit 3 performs a dehumidification function, air is firstly dehumidified by the indoor unit 3, and the temperature is reduced, and the dehumidified cold air is heated by the first auxiliary heating loop 12 and then blown out of the indoor unit 3, so that dehumidification is realized without cooling.
It should be noted that, when the user selects the dehumidification non-cooling mode, the temperature of the user is proper, but the humidity is too high, and only dehumidification is needed, so that intervention of the solar water heating system is needed to achieve the dehumidification, the air-conditioning refrigerant main system and the solar water heating system work simultaneously, at this time, the first electronic expansion valve 9 is opened, the second electronic expansion valve 10 is closed, and the first auxiliary heat circuit 12, the solar heat collector 7 and the storage tank 8 form a circulation circuit, as shown in fig. 4, air firstly passes through the indoor unit 3 of the air-conditioning refrigerant main system to exchange heat with the heat exchange component for dehumidification, and the temperature is reduced, and the dehumidified cold air is heated by the first auxiliary heat circuit 12 and then blown out to the indoor space by the indoor unit 3, so as to achieve dehumidification and non-cooling.
