Abstract

The invention discloses refrigerating equipment. The refrigerating equipment comprises a compressor, an evaporator and a condenser, wherein the compressor, the evaporator and the condenser form a refrigeration cycle, and an air inlet and an air outlet are formed in the compressor; the air inlet communicates with the evaporator through an air inlet pipeline; and the air outlet communicates with thecondenser through an exhaust pipeline. The refrigerating equipment is characterized in that the air inlet pipeline is provided with a first bypass interface; the exhaust pipeline is provided with a second bypass interface; the first bypass interface communicates with the second bypass interface through a connecting pipeline; and a control valve for opening and closing the connecting pipeline is arranged on the connecting pipeline. According to the refrigerating equipment disclosed by the invention, the connecting pipeline is additionally arranged between the conventional air inlet pipeline and the conventional exhaust pipeline, and the control valve for controlling the opening and closing of the connecting pipeline is arranged on the connecting pipeline, so that when the frequency of thecompressor is reduced, the control valve is started to balance the pressure between the air inlet pipeline and the exhaust pipeline, the pressure of a surging source is reduced, the hidden danger of surging is not generated, the service life of the compressor is prolonged, and the whole refrigerating equipment is more stable and reliable to operate.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration device. Background technique [0002] During the operation and use of the air conditioning system, it is often subjected to relatively extreme operating conditions, such as rapid changes in the inlet and outlet water temperatures of the cooling side or the freezing side, and the mismatch between the opening and the speed of the electronic expansion valve, etc. Surge occurs. Surge will cause friction between the moving parts and stationary parts of the compressor, and the abrasion of the moving parts of the compressor will greatly reduce the service life of the compressor, and the air conditioner is prone to various protection abnormalities, and the reliability of the air conditioning system will be affected at the same time. Vital components become fragile. Contents of the invention [0003] The first object of the present invention is to provide a refri...
