Control method and device for condensation prevention of air conditioner and air conditioner

Abstract

The invention discloses a control method and device for condensation prevention of an air conditioner and the air conditioner. The method comprises following steps: determining whether the wind level set by the air conditioner is higher than medium-speed wind level or not when the air conditioner operates in a cooling state and a compressor of the air conditioner is started; obtaining first temperature difference between indoor ambient temperature of the set wind level and inner evaporator tube temperature when the set wind level is less than or equal to the medium-speed wind level and determining whether the first temperature difference satisfies first pre-set temperature of corresponding wind level in different wind levels below the medium-speed wind level; increasing the angle of a wind guide plate, and / or rotating speed of an inner fan of the air conditioner when the first temperature difference is smaller than or equal to the first pre-set temperature and when the angle of the wind guide plate is the pre-set minimum value, and therefore the air conditioner is in the pre-set condensation prevention mode. The technical scheme provided by the control method and device for condensation prevention of the air conditioner and the air conditioner has following beneficial effects: defects in the prior art such as the proneness of generating condensation, bad environmental health and poor users' experience are solved; condensation is not easily generated; the environmental health is good; and users' experience is good.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, in particular to an anti-condensation control method and device for an air conditioner, and an air conditioner, and in particular to an anti-condensation control method for a fixed-frequency air conditioner, a device corresponding to the method, and an air conditioner with the device . Background technique [0002] Air conditioners (i.e. air conditioners) can adjust and control parameters such as temperature, humidity, cleanliness, and speed of the ambient air in buildings / structures. In the cooling or dehumidification mode of the air conditioner, during long-term low-speed operation in a high-humidity environment, when the angle of the air deflector reaches the minimum, the resistance of the air outlet increases, resulting in a decrease in air volume and a decrease in the temperature of the outlet air. In addition, since there is a temperature difference between the outer surface tempe...
