Embodiment Construction
[0039] In the prior art, users mostly use air conditioners to adjust the indoor temperature. When the air conditioner is in cooling operation, sometimes the indoor humidity is high, and the air outlet of the air conditioner is low in temperature and high in humidity, so that condensed water is easy to condense at the air outlet, and drips from the air outlet to the ground, causing user's injury. troubled.
[0040] Generally, the air conditioner simply reduces the frequency of the compressor when preventing condensation and water dripping. When it is detected that the air conditioner is prone to condensation or condensation has already occurred, the frequency of the compressor is reduced. The problem caused by this is that there is no combination of air humidity and the probability of condensation, and the control of the frequency of the compressor is relatively simple, and the indoor temperature cannot be well controlled, which affects the user's requirements for indoor temper...

The invention provides an air conditioner anti-condensation control method and device and an air conditioner, and relates to the technical field of air conditioning. The air conditioner anti-condensation control method comprises the steps that when the air conditioner runs, the relative humidity of the current environment is detected; the judgment is conducted according to the relative humidity, and the air conditioner is controlled to conduct the anti-condensation mode according to the relative humidity; when the anti-condensation mode is operated, the target condensation pipe temperature corresponding to the relative humidity is acquired according to the humidity subinterval which the relative humidity belongs to, and different humidity subintervals correspond to different target condensation pipe temperatures; and the evaporator coil pipe temperature of the current air conditioner is detected, and the running frequency of a compressor of the air conditioner is controlled according to the coil pipe temperature and the target condensation pipe temperature. By the adoption of the air conditioner anti-condensation control method and device and the air conditioner, the accuracy of compressor control conducted by the anti-condensation mode is improved, and the situation that the requirement of a user for the temperature comfort is met in the anti-condensation process is ensured.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner anti-condensation control method and device, and an air conditioner. Background technique [0002] At present, air conditioners usually reduce the operating frequency of the compressor to achieve anti-condensation. For example, condensation is most likely to form when the air conditioner is running at low wind speed (at this time, the wind speed is low and the outlet air temperature is low, and the air moisture is easy to condense). The anti-condensation control method is to reduce the operating frequency of the low wind speed to High wind speed is half the operating frequency. Specifically, when the air conditioner is running at 35°C, the maximum allowable operating frequency of the air conditioner at high wind speed is 80Hz. If the user sets it to low speed, the maximum allowable operating frequency of low wind speed is only 40Hz. The above...
