Air conditioning unit and water hammer elimination control method thereof

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioning unit and a water hammer elimination control method thereof. The invention aims to solve the problem that the water hammer effect elimination mode of an existing air conditioning unit is not very good. For this purpose, the air conditioning unit comprises a compressor, refrigerant supply pipelines connected with the compressor, an evaporator and water hammer eliminating pipelines, wherein a solenoid valve is arranged on each refrigerant supply pipeline or between each refrigerant supply pipeline and the compressor, one end of each water hammer eliminating pipeline is connected to the upstream position of the corresponding solenoid valve, the other end of each water hammer eliminating pipeline is connected to the evaporator, and therefore the refrigerant supply pipelines can directly communicate with the evaporator. When the solenoid valves are suddenly closed, the refrigerant supply pipelines can directly communicate with the evaporator through the water hammer eliminating pipelines; and since the interior of the evaporator is in a low-pressure environment, refrigerantsflowing in the refrigerant supply pipelines can quickly flow into the evaporator through the water hammer eliminating pipelines, consequently the water hammer effect in each pipeline is effectively eliminated, and then the solenoid valves and the pipelines are effectively protected.

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...
