Abstract

The invention provides a frequency converter cooling system. The frequency converter cooling system comprises a compressor, a cooling assembly and a frequency converter cooling module. An exhaust port of the compressor, the cooling assembly, the frequency converter cooling module and an air suction port of the compressor are sequentially connected through a pipeline to form a refrigerant loop. The frequency converter cooling module is used for cooling a frequency converter. According to the above frequency converter cooling system, a refrigerant is directly used for flowing through the frequency converter cooling module to cool the frequency converter. The problems that the structure is complex and the size is large when a freezing water circulation cooling system and a refrigerant circulation cooling system need to be installed at the same time are solved. In addition, the heat exchange process of freezing water and the refrigerant is omitted, the refrigerant is directly used for cooling the frequency converter, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a frequency converter cooling system, an air conditioner unit and a control method. Background technique [0002] In the traditional technology, chilled water circulation is used to cool the frequency converter. One of the ways to obtain the cold source is to obtain the cold source from other independent air-conditioning systems. This method often requires the construction of pipelines connected to other independent air-conditioning systems , causing the engineering installation to remain unchanged and occupy a large area. Another way to obtain the cold source is to obtain the cold source from the refrigeration cycle system of the unit itself. This cooling method must be realized when the refrigeration cycle system of the unit is working. In some special cases, such as photovoltaic air conditioning units, When the air-conditioning unit only operates in photovolta...
