Two-stage enthalpy increasing compressor and air conditioner

Abstract

The invention provides a double-stage enthalpy-increasing compressor and an air conditioner. The double-stage enthalpy-increasing compressor comprises a liquid distributor part, an air suction pipe, a pump body and an enthalpy increasing assembly, wherein the pump body comprises a low pressure cylinder and a lower flange, the low pressure cylinder is fixedly connected with the lower flange, the liquid distributor part is communicated with the low pressure cylinder by virtue of the air suction pipe, a middle cavity and a lower flange enthalpy-increasing hole are formed in the lower flange, the low pressure cylinder is communicated with the middle cavity, a low pressure cylinder enthalpy increasing hole is formed in the low pressure cylinder, the low pressure cylinder enthalpy increasing hole corresponds to the lower flange enthalpy increasing hole, and the enthalpy increasing assembly is in interference fit to the low pressure cylinder enthalpy increasing hole and is communicated with the middle cavity by virtue of the lower flange enthalpy increasing hole; a non-return device is arranged on the lower flange enthalpy increasing hole, and the non-return device is arranged at one end, adjacent to the lower pressure cylinder, of the lower flange enthalpy increasing hole. The double-stage enthalpy-increasing compressor is simple in structure, low in cost and convenient to install, and middle-pressure gas can be prevented from reversely flowing to or flowing back to a system air replenishing pipe, so that the power consumption of the compressor is reduced, and the operating efficiency of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a two-stage enthalpy-increasing compressor and an air conditioner. Background technique [0002] Under the sustainable development theme of high efficiency, energy saving and environmental protection, two-stage enthalpy-increasing compressors are more and more widely used in heat pump products. The application in enthalpy compressors has been relatively mature, but this technology has the problem that the medium-pressure gas in the intermediate channel flows back or flows back to the system air supply pipe, which increases the loss of the medium-pressure flow group and reduces the high-pressure suction pressure. Increased power consumption reduces the efficiency and performance of the two-stage enthalpy-enhancing compressor.
