Variable-frequency air conditioner and condensation prevention control method for variable-frequency module radiator of variable-frequency air conditioner

Abstract

The invention relates to the field of air conditioners and discloses a variable-frequency air conditioner and a condensation prevention control method for a variable-frequency module radiator of the variable-frequency air conditioner. The variable-frequency air conditioner comprises a main refrigerant flow way (512a) capable of cooling the variable-frequency module radiator (6) and a parallel connection refrigerant flow way (512b), wherein the parallel connection refrigerant flow way and the main refrigerant flow way are arranged in parallel. The condensation prevention control method comprises the steps of S1, the temperature detection, wherein the temperature Tf of the variable-frequency module radiator (6) and the temperature Ti of the environment where the variable-frequency module radiator is located are detected; S2, the temperature control, wherein when Tf is smaller than Ti, the flow of a refrigerant flowing the parallel connection refrigerant flow way (512b) is increased to reduce the flow of the refrigerant flowing the main refrigerant flow way (512a), so that the situation that the flow of the refrigerant taking participating in the cooling variable-frequency module radiator is excessive, and consequently the surface temperature of the cooling variable-frequency module radiator is lowered to below the air dew point temperature of the environment is avoided, and condensed water is effectively prevented from being generated on the variable-frequency module radiator on the premise of guaranteeing the good heat dissipation effect.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an anti-condensation control method for a frequency conversion module radiator of a frequency conversion air conditioner. In addition, the invention also relates to an inverter air conditioner. Background technique [0002] In the multi-connected system that uses refrigerant to cool the radiator of the frequency conversion module, it is easy to cause the surface temperature of the frequency conversion module to be lower than the dew point temperature of the surrounding air under certain operating conditions, and then generate condensation on the radiator of the frequency conversion module, affecting the air conditioning system reliable operation. [0003] For the sake of safety, people still tend to adopt the air source multi-connected system, and use the ambient air flow to cool the radiator of the inverter module, but it is difficult to obtain a good heat dissipation effect. ...
