The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator in the present application. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the 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. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. 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.

Referring to fig. 1, an air conditioner system includes;

a control module 510 built in the indoor unit 500;

the control module 510 collects temperature data of the temperature sensor by using a wireless communication module 520;

wherein the control module 510 stores the set temperature T0 of the space; the control module 510 is configured to screen an actual temperature T of the space according to an operation mode of the air conditioner system; the control module 510 is further configured to control the operating state of the compressor according to the comparison of the set temperature T0 and the actual temperature T.

The utility model discloses an in some embodiments, because the air conditioner can meet different scene questions in actual installation and use, it is great to lead to return air inlet temperature and actual ambient temperature difference, and the temperature on the line accuse ware also differs great with current ambient temperature simultaneously. For example, in winter, hot air generally has a relatively light specific gravity and is relatively easy to accumulate near the return air inlet of the indoor unit of the air conditioner, and when the indoor temperature does not reach the set temperature, the temperature near the return air inlet may be relatively high and even reach the temperature set by a user; a heat source may exist near the wire controller, and even the wire controller may be influenced by direct sunlight and other reasons, and the temperature acquired by the temperature detection module is higher than the actual indoor environment temperature; at the moment, the air conditioning system can be misjudged, so that the room environment temperature reaches the set temperature of the user, and then the shutdown operation is triggered, and the experience brought to the user is not good at the moment. Therefore, in this embodiment, four temperature sensors are taken as an example, and as shown in fig. 1, the four temperature sensors are respectively a first temperature sensor 100, a second temperature sensor 200, a third temperature sensor 300 and a fourth temperature sensor 400. The height of the mounting position of the first temperature sensor 100 is the highest, the height of the mounting position of the second temperature sensor 200 is the second highest, the height of the mounting position of the fourth temperature sensor 400 is the lowest, and the height of the mounting position of the third temperature sensor 300 is between the second temperature sensor 200 and the fourth temperature sensor 400. During the operation of the air conditioner system, the control module 510 continuously collects the temperatures of the first temperature sensor 100, the second temperature sensor 200, the third temperature sensor 300, and the fourth temperature sensor 400 according to a fixed period, which are respectively denoted as an indoor temperature T1, an indoor temperature T2, an indoor temperature T3, and an indoor temperature T4.

firstly, if the indoor temperature values detected by the indoor temperature T1, the indoor temperature T2, the indoor temperature T3 and the indoor temperature T4 for N consecutive times (wherein N > 3) do not conform to the arrangement sequence of T1> T2> T3> T4, rejecting the temperature values of abnormal points; and taking the highest temperature value out of the rest temperature values, recording the highest temperature value as Tm, and recording the lowest temperature value as Tn.

Secondly, comparing Tm with the temperature Th of the air return inlet, and if Tm is larger than Th, recording the maximum value Tmax = Th of the indoor temperature; otherwise, the maximum indoor temperature Tmax = Tm;
