Air-conditioning unit and its water hammer elimination control method

Abstract

The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning unit and a water hammer elimination control method thereof. The invention aims to solve the problem that the methods for eliminating the water hammer effect of the existing air conditioning units are not very good. For this reason, the air conditioning unit of the present invention includes a compressor, a refrigerant supply pipeline connected to the compressor, an evaporator and a water hammer elimination pipeline, and a solenoid valve is arranged on the refrigerant supply pipeline or between the refrigerant supply pipeline and the compressor. One end of the water hammer elimination pipeline is connected to the upstream of the solenoid valve, and the other end of the water hammer elimination pipeline is connected to the evaporator, so that the refrigerant supply pipeline can directly communicate with the evaporator; when the solenoid valve is suddenly closed, the refrigerant supply pipe The pipeline can be directly connected to the evaporator through the water hammer elimination pipeline. Since the interior of the evaporator is a low-pressure environment, the refrigerant flowing in the refrigerant supply pipeline can quickly flow into the evaporator through the water hammer elimination pipeline, thereby effectively eliminating The water hammer effect can form an effective protection for the solenoid valve and pipeline.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning unit and a water hammer elimination control method thereof. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air-conditioning units have become an essential device in people's lives. Although the various designs of air-conditioning units have become more and more mature in recent years, there are still some problems in the existing air-conditioning units; for example, the electromagnetic valve in the existing air-conditioning It will cause a great impact on the nearby pipelines. This impact will not only cause severe vibrations in the pipelines, but may also cause damage to the pipelines and solenoid valves. [0003] In order to avoid the generation of w...
