Abstract

The invention provides a frequency converter cooling device. The frequency converter cooling device comprises a refrigerant cooling system and a freeze water cooling system. A compressor, a cooling assembly and a heat exchanger assembly of the refrigerant cooling system are successively connected through a pipeline to form a refrigerant loop; a freeze water inlet pipe, a frequency converter cooling module, a freeze water outlet pipe and the heat exchanger assembly of the freeze water cooling system are successively connected to form a freeze water loop. According to the frequency converter cooling device, heat exchange for cooling is performed between water in the freeze water cooling system and a refrigerant in the refrigerant cooling system in the heat exchanger assembly, and the frequency converter is further cooled by virtue of water in the freeze water cooling system, and the frequency converter can be cooled in real time even if a circular cooling system of the air conditioning unit where the frequency converter is does not operate, so that the operating safety of the frequency converter is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a frequency converter cooling device, an air conditioner unit and a control method. Background technique [0002] In the traditional technology, one way of cooling the frequency converter in the air conditioning unit is to obtain the cold source from other independent air conditioning systems. This cooling method often requires the construction of pipelines connected to other independent air conditioning systems, resulting in unchanged engineering installation. , and takes up a lot of space. Another way to cool the frequency converter in the air conditioning unit is to obtain the cold source from the refrigeration cycle system of the unit itself. This cooling method can only be realized when the refrigeration cycle system of the unit is working. In some special cases, such as photovoltaic In the air-conditioning unit, when the air-conditioning unit only operates ...
