Heating device of scroll compressor

Abstract

The invention discloses a heating device of a scroll compressor and relates to the technical field of air conditioning. The heating device comprises a casing, wherein an air inlet is formed in the right end of the casing; the left end of the casing is in threaded connection with an end cover through a screw; an exhaust port is formed in the outer surface of the end cover; and a PTC heating deviceis arranged in the casing. According to the heating device, a PTC heating body is arranged to convert electric energy into thermal energy under the action of a wiring terminal, so that the suction temperature of the compressor can be effectively increased to directly increase the discharge temperature of the compressor, the heating performance of an air conditioning system is improved, the problemthat the heating capacity of the existing air conditioning compressor is low at the low temperature heating state is solved, the purpose that the absorbed air of the air conditioning compressor is rapidly heated to increase the discharge temperature of the compressor accordingly is realized, the air conditioner is forced to improve the heating efficiency at the low temperature state, the waitingtime of a user is effectively shortened, and the degree of satisfaction of the user is increased.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heating device for a scroll compressor. Background technique [0002] When the air conditioner is heating, the gas refrigerant is pressurized by the compressor to become a high-temperature and high-pressure gas, enters the heat exchanger of the indoor unit (in this case, the condenser), condenses and liquefies, releases heat, and becomes a liquid, and at the same time heats the indoor air, thereby achieving The purpose of increasing the indoor temperature is that the refrigerant evaporates into gas in the outdoor unit and absorbs the heat in the air. Therefore, the evaporation temperature of the refrigerant must be lower than the outdoor temperature. When the compressor is working, it compresses the gas. During the compression process, the gas As the pressure increases, the temperature also rises. The temperature of the compressor suction gas is low, and the temperatur...
