Problems solved by technology

[0004] However, in the above-mentioned air conditioning system, the temperature of the refrigerant flowing into the cooling pipe from the inlet end may be lower than the dew point temperature of the air, so dew condensation may occur on the inlet end side of the electrical component cooling pipe. , dew condensation water may drip to the electrical components that make up the air conditioning system, etc., causing problems such as short circuits, which is not ideal

Abstract

The invention provides an air conditioner system which can protect part of electrical element cooling pipe forming a refrigerant pipe against condensation. The air conditioner system comprises a compressor, an outdoor heat exchanger and an indoor heat exchanger which are connected through the refrigerant pipe in sequence. The refrigerant pipe between the outdoor heat exchanger as the indoor heat exchanger comprises a cooling pipe provided with an inlet end and an outlet end. The cooling pipe comprises a first branch pipe and a second branch pipe arranged between the inlet end and the outlet end in parallel. The casting pipe type electrical element cooling pipe is arranged on the first branch pipe. A flow control element is arranged on the second branch pipe.

Description

technical field [0001] The present invention relates to an air-conditioning system, in particular to an air-conditioning system which uses a cooling pipeline to cool electrical components. Background technique [0002] In the past, there was an air-conditioning system, which included a compressor, an outdoor heat exchanger, and an indoor heat exchanger sequentially connected by a refrigerant pipeline, and the refrigerant pipeline between the outdoor heat exchanger and the indoor heat exchanger included a And a cooling pipeline at the outlet end, the cooling pipeline has an electrical component cooling tube that contacts the heat-generating electrical component through a metal plate. [0003] In the above air conditioning system, the electrical components can be cooled by the refrigerant that flows through the cooling pipe of the electrical components due to the heat exchange with the air in the outdoor heat exchanger and the temperature of the electrical components is cooled...
