The invention provides an air conditioning system and an anti-condensation control method and device thereof and a storage medium. The air conditioning system comprises an outdoor unit, at least one indoor unit, a hydraulic power module and a liquid pipe, wherein the outdoor unit is connected with at least one indoor unit and the hydraulic power module, the outdoor heat exchanger outdoors is connected with the first end of a radiator through a throttling device, the at least one indoor unit and the hydraulic power module are connected with the second end of the radiator through the liquid pipe, the radiator is used for cooling an electronic control component in the outdoor unit, and the hydraulic power module comprises a second compressor. The method comprises the following step that 1, the outdoor unit is identified for refrigeration operation, and the outside ambient temperature and the first pressure of an exhaust port of the first compressor is obtained; and 2, the operating frequency of the second compressor is controlled according to the outside ambient temperature and the first pressure, so that the radiator in the outdoor unit is prevented from being condensed, and the electric control component arranged on the outdoor unit and cooled by a refrigerant is effectively prevented from being condensed when the heat recovery multi-split system refrigeration operation is performed.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system, its anti-condensation control method and device, and a storage medium. Background technique [0002] In related technologies, the functions of multi-connected external units are gradually increasing, and the number of power devices carried is also increasing, and the heat generated by the electric control box is increasing. When the refrigerant is used to cool the electronic control box, due to the complex working conditions of the heat recovery multi-connected system, improper control can easily cause the temperature of the electronic control components to be lower than the dew point temperature, resulting in condensation of the electronic control components and affecting the reliability of the electronic control components. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the r...
