Embodiment 1
[0086] The constant temperature dehumidification control method of this application can refer to figure 1 , mainly including steps:
[0087] A1. After the air conditioner is in the constant temperature dehumidification mode and runs for the first time, the current relative humidity is detected to obtain the first relative humidity.
[0088] Obtain the running time t of the air conditioner in the constant temperature dehumidification mode, and determine whether the running time is greater than or equal to the first running time t 1 , if so, get the first relative humidity RH 当前1 . Exemplarily, the value of the first running time can be t 1 ∈[60min,+∞).
[0089] If you want to adjust the relative humidity as soon as possible, you can set t 1 Set it to a relatively small value within the range, for example: 60min.
[0090] A2. Obtain a first relative humidity difference, where the first relative humidity difference is a difference between the first relative humidity and a s...
Embodiment 2
[0124] The above embodiment can improve the water blowing situation of the indoor unit by adjusting the operating frequency of the compressor; however, when the outdoor temperature is high, the operating frequency of the compressor needs to be kept at a relatively high level, and the operating frequency of the compressor can be increased to Insufficient room for downward adjustment. When the indoor humidity is high, condensation is likely to occur, which makes the possibility of water blowing from the indoor unit more likely. Therefore, the embodiment of the present application proposes to increase the temperature of the evaporator by adjusting the rotation speed of the outdoor unit and / or the opening of the electronic expansion valve, thereby reducing the occurrence of water blowing of the indoor unit. see figure 2 , figure 2 It is a schematic flow chart of another constant temperature dehumidification control method shown in the embodiment of this application. Another em...
Embodiment 3
[0177] In the constant temperature dehumidification mode, the air conditioner needs to reduce the relative humidity while controlling the room temperature.
[0178] Figure 4 It is a structural schematic diagram of the air conditioner indoor unit shown in the embodiment of the present application.
[0179] An air conditioner for implementing the constant temperature and dehumidification control methods of Embodiment 1 and Embodiment 2, comprising: an air conditioner indoor unit and an outdoor unit connected to each other.
[0180] see Figure 4 , the air conditioner internal unit includes: an evaporator forming a refrigerant circuit, a multi-way valve, a compressor, a condenser and an electronic expansion valve;
[0181] Wherein, the evaporator is provided with an electromagnetic two-way valve.
[0182] The electromagnetic two-way valve divides the evaporator into two sections, one of which is a reheating section and the other is a dehumidification section, the temperature ...
