Capillary steam mixed supercavitation injection noise suppression device

Abstract

The invention relates to a capillary steam admixture supercavitation jet noise suppression device, which is a device for introducing the refrigerant gas in the middle of the evaporator into the outlet of the capillary tube through a bypass capillary tube, so as to carry out steam admixture for the refrigerant coming out of the capillary tube and entering the evaporator, improving the performance of the evaporator. The local pressure in the steam mixing area can effectively reduce the cavitation number, significantly reduce the pressure when the cavitation collapses, form a phenomenon of super cavitation, and greatly reduce the noise of cavitation and cavitation; the mixed refrigerant flows into the evaporator to complete Compared with the traditional muffler, the present invention has the advantages of simple structure, convenient processing and installation, and low maintenance cost in the later period; and the present invention is widely used, not only suitable for common refrigeration devices such as refrigerators, air conditioners, etc., but also for machinery, metallurgy, etc. , petroleum, chemical, food preservation, artificial environment, biopharmaceutical and other fields of refrigeration systems can use this noise suppression device.

Description

technical field [0001] The invention relates to a new type of spray noise reduction and suppression device, specifically, a refrigerant gas in the middle of the evaporator is introduced into the outlet of the capillary through a bypass capillary, so that the refrigerant coming out of the capillary into the evaporator is mixed with steam. , increase the local pressure in the steam-mixed area, effectively reduce the cavitation number, significantly reduce the pressure when the cavitation collapses, form a supercavitation phenomenon, and greatly reduce the cavitation noise. The mixed refrigerant then flows into the evaporator to complete the cycle. Background technique [0002] The noise research of the refrigeration system shows that, in addition to the mechanical noise and electromagnetic noise of the compressor itself, the flow noise of the system itself directly affects the noise level of the refrigeration system and the sound quality parameters of the refrigeration system,...
