Abstract

The invention relates to the field of air conditioners and discloses a frequency conversion air conditioner and a condensation-preventing control method for a frequency conversion module radiator of the frequency conversion air conditioner. The frequency conversion air conditioner comprises an intermediate heat exchanger (5). The intermediate heat exchanger (5) comprises a main heat exchange flow path (51) and an auxiliary heat exchange flow path (52). The refrigerating outlet end of the main heat exchange flow path (51) is provided with a first branch flow path (511) connected to the inlet end of the auxiliary heat exchange flow path, and a second branch flow path (512) arranged to be capable of cooling the frequency conversion module radiator (6). The first branch flow way is provided with a branch throttling part (511a). The condensation-preventing control method includes the steps that S1, the temperature Tf of the frequency conversion module radiator and the environment temperature Ti of the environment where the frequency conversion module radiator is located are detected; and S2, when Tf is smaller than Ti, the refrigerant flow flowing through the auxiliary heat exchange flow way is reduced, it is avoided that the refrigerant temperature of a refrigerant flowing through the second branch flow way is reduced to the temperature below the environment air dew point temperature, and therefore condensation water is effectively prevented from being generated on the frequency conversion module radiator.

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. ...
