According to the wall-mounted air conditioner indoor unit 1 of the embodiment of the utility model, the shell 100 is provided with the air inlet 110 and the air outlet 120, the heat exchanger 200 is arranged in the shell 100 and used for exchanging heat with indoor air, the fan is arranged in the shell 100, the indoor air is guided into the shell 100 from the air inlet 110 through the operation of the fan, heat exchange airflow is formed through the heat exchanger 200 and is guided back into the room from the air outlet 120, the electric control box 300 is respectively connected with the heat exchanger 200 and the fan and used for controlling the operation of the heat exchanger 200 and the fan, that is, when the wall-mounted air conditioner indoor unit 1 is used for indoor refrigeration or heating, the electric control box 300 can control the heat exchanger 200 and the fan to start to operate, and the fan operates to guide indoor air to enter the shell 100 from the air inlet 110 and is discharged into the room from the air outlet 120 after exchanging heat with the heat exchanger 200 in the shell 100, so that indoor refrigeration or heating is realized.
In addition, the electric control box 300 is arranged in the shell 100 and is arranged at intervals with the heat exchanger 200 along the length direction of the shell 100, the mounting plate 310 is arranged on the outer surface of the electric control box 300, the temperature sensing probe 400 is arranged on the mounting plate 310 and is electrically connected with the electric control box 300, and the temperature sensing probe 400 is used for detecting the return air temperature and feeding back the return air temperature to the electric control box 300 and is arranged at intervals with the heat exchanger 200. The return air temperature refers to the temperature of the air entering the housing 100 from the air inlet 110.
Thus, the temperature sensing probe 400 can detect the temperature of the indoor air and feed back the temperature to the electronic control box 300, and then the operation of the indoor unit 1 of the wall-mounted air conditioner can be adjusted according to the indoor temperature, for example, when the indoor temperature is close to or the same as the set temperature of the indoor unit 1 of the wall-mounted air conditioner, the power of the indoor unit 1 of the wall-mounted air conditioner can be reduced, so as to reduce the power consumption of the indoor unit 1 of the wall-mounted air conditioner and keep the indoor temperature at the set temperature value, or when the difference between the indoor temperature and the set temperature of the indoor unit 1 of the wall-mounted air conditioner is larger, the power of the indoor unit 1 of the wall-mounted air conditioner can be kept higher, so that the indoor temperature can be quickly adjusted, and the user experience can be improved.
It can be understood that if the heat radiation of the heat exchanger 200 has a large influence on the temperature sensing probe 400, the return air temperature detected by the temperature sensing probe 400 is the sum of the actual return air temperature and the temperature affected by the heat radiation of the heat exchanger 200, which may cause the return air temperature detected by the temperature sensing probe 400 to be higher than the actual indoor temperature. Thus, when the indoor unit 1 of the wall-mounted air conditioner cools, the indoor temperature reaches the preset temperature value, but the return air temperature detected by the temperature sensing probe 400 is higher than the preset temperature value, the indoor unit 1 of the wall-mounted air conditioner still operates at high power to cool the room, so that the final indoor temperature is lower than the preset temperature value, and the cooling is excessive; when the wall-mounted air conditioner indoor unit 1 heats, the indoor temperature does not reach the preset temperature value, but the return air temperature detected by the temperature sensing probe 400 is already equal to the preset temperature value, the wall-mounted air conditioner indoor unit 1 operates at low power, so that the final indoor temperature is lower than the preset temperature value, and the refrigeration is insufficient.

In addition, at least a part of the mounting plate 310 is located between the temperature sensing probe 400 and the heat exchanger 200 to separate the temperature sensing probe 400 and the heat exchanger 200, that is, in the length direction of the shell 100, the mounting plate 310 can separate the temperature sensing probe 400 and the heat exchanger 200, so that the temperature sensing probe 400 can be fixed on the electric control box 300, the temperature sensing probe 400 is far away from the heat exchanger 200, the heat exchanger 200 and the temperature sensing probe 400 can be further separated through the mounting plate 310, the influence of heat radiation of the heat exchanger 200 on the temperature measurement of the temperature sensing probe 400 is effectively avoided, the influence of heat exchange wind flowing through the heat exchanger 200 on the temperature sensing probe 400 can be reduced, the temperature sensing probe 400 can detect return air temperature more accurately, the refrigeration and heating of the indoor unit 1 of the wall-mounted air conditioner are more accurate, and the use experience of a user is further improved.

The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a 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 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. In the whole cycle, the wall-mounted air conditioner indoor unit 1 can adjust the temperature and humidity of the indoor space.
