Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 , figure 2 As shown, a compressor liquid shock prevention device includes a controller 1 , a pressure-resistant refrigerant metal container 5 , a temperature sensor 3 and a pressure sensor 2 . The present invention is used in a refrigeration cycle circuit composed of a compressor, a condenser, an expansion valve, an evaporator, and a gas-liquid separator. One side of the pressure-resistant refrigerant metal container 5 is provided with an inlet, and the other side is provided with an outlet. The refrigeration cycle In the circuit, the outlet of the compressor is connected to the inlet of the condenser, the outlet of the condenser is connected to the inlet of the expansion valve, the outlet of the expansion valve is connected to the inlet of the evaporator, the outlet of the evaporator is connected to the inlet of the gas-liquid...

Abstract

The invention discloses a compressor liquid impact prevention device. The compressor liquid impact prevention device comprises a controller, a pressure-resistant refrigerant metal container, a temperature sensor and a pressure sensor, wherein refrigerant returns to a compressor suction port through the pressure-resistant refrigerant metal container; the pressure-resistant refrigerant metal container is provided with a heating device; the temperature sensor detects the internal temperature of the pressure-resistant refrigerant metal container; the pressure sensor detects the internal pressure of the pressure-resistant refrigerant metal container; and the controller controls the heating device to work according to data collected by the temperature sensor, so that the refrigerant flowing through the pressure-resistant refrigerant metal container is kept in a gaseous state and enters the compressor suction port, and compressor damage caused by compressor liquid impact can be prevented.

Description

technical field [0001] The invention relates to the field of compressor protection devices, in particular to a compressor liquid shock prevention device. Background technique [0002] With the development of the refrigeration industry, refrigeration principles and technologies have been relatively mature. In the main components of refrigeration, the compressor, condenser section, flow device (expansion valve), and evaporator, the protection of the compressor is particularly important. In the field of protection, as we all know, the liquid state is incompressible, but the gas is compressible. Once the liquid refrigerant enters the compressor, it will be damaged due to liquid shock. The current measure is to add a gas-liquid separation device before the suction port of the compressor in the system, but it cannot completely solve the problem. Compressor liquid hammer phenomenon, such as in areas with low ambient temperature (such as military equipment -40 ℃ test, etc.), or in a...
