[0043] Please check figure 1 , the control method of the air conditioner anti-condensation provided by the present embodiment, comprises the following steps:

[0044] S11: Detect the temperature T1 of the inner disk and the dew point temperature T2 of the inner ring.

[0045] Among them, the inner disk temperature T1 represents the coil temperature of the indoor evaporator, and the inner ring dew point temperature T2 represents the indoor dew point temperature. Both the inner panel temperature T1 and the inner ring dew point temperature T2 are measured by temperature sensors or temperature and humidity sensors. The timing of measurement can be after the air conditioner is turned on in cooling mode, and the air conditioner continues to run for a preset period of time. The preset period of time can range from 3 minutes to 8 minutes, preferably 5 minutes, so that the temperature can be detected after the air conditioner is running stably, which can improve the accuracy of the da...

[0053] Please check figure 2 , the control method of the air conditioner anti-condensation provided by the present embodiment, comprises the following steps:

[0054] S21: After the air conditioner starts the cooling mode, continue to run the air conditioner for a preset period of time.

[0055] When the air conditioner is in cooling mode, there is a risk of condensation on the surface of the evaporator on the indoor side, and anti-condensation control is required.

[0056]Wherein, the range of the preset duration may be 3 minutes to 8 minutes, preferably 5 minutes. In this way, the temperature can be detected after the air conditioner is running stably, which can improve the accuracy of the data.

[0057] S22: Detect the relative humidity X in the room, and judge whether the relative humidity X is greater than the preset humidity A.

[0058] Wherein, the range of the preset humidity A is: RH60%-RH100%, specifically RH70% can be selected. When the relative humidity X is gr...

Abstract

The invention provides an air conditioner condensation preventing control method and an air conditioner, and relates to the technical field of air conditioners. The control method comprises the stepsthat the inner disc temperature T1 and the inner ring dew point temperature T2 are detected; and whether the condensation risk exists or not is judged according to the inner disc temperature T1 and the inner ring dew point temperature T2; when the condensation risk exists, the step number of an electronic expansion valve is controlled to be increased or the frequency of a compressor is controlledto be reduced. Accordingly, when the condensation risk is detected, the step number of the electronic expansion valve is controlled to be increased, the flow of a refrigerant can be increased, or thefrequency of the compressor is reduced, the temperature of the refrigerant is increased, accordingly, the surface water evaporation efficiency of an indoor evaporator is improved, the water accumulating amount in the system is reduced, and condensation is avoided. In the whole process, air outlet temperature fluctuation is not caused, constant-temperature dehumidification is achieved, the dehumidification amount is large, and dehumidification is stable.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner anti-condensation control method and the air conditioner. Background technique [0002] There is a lot of rain in spring, and the humid climate often occurs in March and April, causing furniture, clothes, etc. to regain moisture and become moldy. Consumers often use the dehumidification function of air conditioners to reduce room humidity. The dehumidification function of air conditioners generally adopts the method of reducing enthalpy and dehumidification, that is, reducing the air temperature in the environment, making the air temperature lower than the dew point temperature of high-humidity air, and realizing moisture from the air. The dehumidification effect of this method is better. Due to the small air volume in the dehumidification process of this method, there is more water in the system, which is prone to condensation and drips to the ground...
