Description

A heat exchange system for an oil-cooled air conditioner

technical field

The invention relates to the technical field of air conditioners, in particular to a heat exchange system for oil-cooled air conditioners.

Background technique

Air conditioners are an important electrical appliance that is indispensable in current life production and work production. The air conditioner is mainly composed of the internal unit, the external unit and the pipeline. The most important component of the air conditioning equipment is the compressor, which plays an important role in the "heart" of the entire air conditioning system. Therefore, the state of the compressor should be valued and protected.

The air conditioner compressor, in all the current air conditioner systems, is in an independent space with only a simple protective effect, and the compressor will generate a lot of heat when it is working. This heat is quite large and cannot be ignored. Not only will it affect the service life of the compressor, but more importantly, it will affect the operation of the entire air-conditioning system. If the compressor fails due to high temperature, the loss outweighs the gain, although there are relatively few cases of compressor failure due to high temperature , but it also exists objectively. Moreover, with people's dependence on air conditioners, the time to turn on the air conditioner is also rising linearly. In addition, the external ambient temperature is also increasing year by year. Therefore, it is necessary to protect the air conditioner compressor from heat dissipation. Therefore, we propose a heat exchange system for oil-cooled air conditioners to solve the problem of compressor heat exchange.
