Embodiment Construction

[0017] See figure 1 , 2 , A device for preventing compressor liquid strike, including compressor 1, controller 2, solenoid valve 3 and pressure sensor 4. Solenoid valve 3 is connected to the return line of compressor 1, which can control refrigerant flow and pressure The sensor 4 is connected in the air return pipeline between the solenoid valve 3 and the compressor 1. The controller 2 is electrically connected to the pressure sensor 4 on the one hand, and is electrically connected to the compressor 1 and the solenoid valve 3 on the other hand. The pressure sensor 4 detects The pressure in the return gas pipeline is transmitted to the controller 2, and the controller 2 controls the start and stop of the solenoid valve 3 and the compressor 1 respectively.

[0018] A method for preventing compressor liquid hammer, specifically includes the following steps:

[0019] (1) When the refrigeration is stopped, the controller 2 controls the solenoid valve 3 to open and cut off the refrigeran...

Abstract

The invention discloses a device and a method for preventing liquid impact of a compressor. The device comprises the compressor, a controller, an electromagnetic valve and a pressure sensor, wherein the electromagnetic valve is connected with an air return pipe of the compressor to control flow of a refrigerant; the pressure sensor is connected with an air return pipe between the electromagnetic valve and the compressor; the controller is electrically connected with the pressure sensor on one hand, and on the other hand, the controller is electrically connected with the compressor and the electromagnetic valve; the pressure sensor detects pressure of the air return pipe and transmits the pressure to the controller; and the controller controls start-stop of the electromagnetic valve and the compressor. The device solves the problem about liquid impact of the compressor, and is simple in structure, easy to manufacture, safe, reliable and wide in application range and can be widely used in an air conditioning system.

Description

Technical field [0001] The invention relates to the field of air conditioning systems, in particular to a device and method for preventing compressor liquid hammer. Background technique [0002] The position of the air return pipe in the air-conditioning system tends to collect liquid refrigerant. When the compressor is working, the phenomenon of compressor liquid hammer will occur, which will cause damage to the compressor and affect the use and life of the air conditioner. Summary of the invention [0003] The purpose of the present invention is to provide a device and method for preventing compressor liquid hammer, which can effectively prevent the compressor from generating liquid hammer. [0004] The technical scheme of the present invention is as follows: [0005] A device for preventing compressor liquid hammer, comprising a compressor, a controller, a solenoid valve and a pressure sensor, characterized in that: the solenoid valve is connected to the air return pipeline of the...
