Efficient and energy-saving vehicle-mounted air conditioning compressor

Abstract

The invention discloses an efficient and energy-saving vehicle-mounted air conditioning compressor which comprises a compressor body, wherein a gas outlet and a gas inlet on the compressor body are respectively connected with an oil-gas separation device and a heat exchange device; the oil-gas separation device comprises a cylinder; a lubricating oil separation assembly is laid in the cylinder; the lubricating oil separation assembly is vertically provided with a separation gas inlet pipe in a running-through manner; a separation exhaust opening is arranged at the side wall of the cylinder; the separation gas inlet pipe penetrates through the top of the cylinder and communicates with the gas outlet through a pipe; and an oil drainage opening is arranged at the bottom of the cylinder. Compared with the prior art, the efficient and energy-saving vehicle-mounted air conditioning compressor separates the lubricating oil from the mixed gas flow of the lubricating oil and refrigerants, thereby improving the compressor efficiency of the vehicle-mounted air conditioning compressor and improving the heat exchange efficiency of a condenser and an evaporator. By virtue of the structure of a heat exchange pipeline system and a liquid supplement valve, the efficient and energy-saving vehicle-mounted air conditioning compressor realizes the preheating of the low-temperature and low-pressuregas refrigerants and the precooling of the high-temperature and high-pressure liquid refrigerants so as to further reduce the energy consumption of the compressor and achieve the purpose of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of vehicle air-conditioning compressors, in particular to a high-efficiency and energy-saving vehicle-mounted air-conditioning compressor. Background technique [0002] With the development of the automobile manufacturing industry, the research on automobile air conditioning technology is getting faster and faster. The automotive air-conditioning compressor is the core component. During the operation of the compressor, energy saving is necessary for energy conservation and environmental protection. The automotive air-conditioning compressor compresses the refrigerant during operation, and at the same time a large amount of lubricating oil enters the compressor and is compressed from the exhaust. The air port is directly discharged, and the refrigerant carries lubricating oil to circulate in the refrigeration component. Since the proportion of lubricating oil is about 5% to 10%, it affects the compression eff...
