Problems solved by technology

[0004] In the materials disclosed in the related art, some heat pump systems adopt an ejector structure. The compressor in the heat pump system is an air injection enthalpy increasing compressor, and the ejector injects air towards the air supply port of the compressor. This structure is not suitable for systems with ordinary compressors. middle

Abstract

The invention discloses an air conditioner. The air conditioner comprises a compressor, an ejector, a reversing assembly, an indoor heat exchanger, an outdoor heat exchanger and a gas-liquid separator, wherein a coolant outlet of the ejector is connected with an air return opening of the compressor; the reversing assembly is provided with four ports, wherein a first port is connected with an air outlet of the compressor, a second port is connected with an injection inlet of the ejector, the indoor heat exchanger is connected with a third port, and the outdoor heat exchanger is connected with a fourth port; the gas-liquid separator is provided with three interfaces, wherein a first interface is connected with the indoor heat exchanger, a second interface is connected with the outdoor heat exchanger, and a third interface is connected with an ejecting inlet of the ejector so as to enable gaseous coolants to be introduced into the ejector. According to the air conditioner disclosed by the invention, the heat exchange efficiency of the heat exchangers is improved, the ejector not only can heat returned air of the compressor and increase the degree of superheat of the returned air but also can recover partial throttling loss work and improve the energy efficiency of the air conditioner. The air conditioner is simple and reasonable in structure, high in running efficiency, wide in application range and excellent in low-temperature heating effects.

Description

technical field [0001] The invention relates to the field of refrigeration and heating equipment, in particular to an air conditioner. Background technique [0002] Relevant materials point out that in some applications of the refrigerant circulation system, such as heat pump applications in low temperature environments, due to the reduction of the evaporation temperature, the capacity of the refrigerant circulation system is reduced, and the performance of ordinary single-stage rotary compressors is deteriorated and cannot be used. [0003] The ejector can recover system throttling loss work, increase suction pressure, etc. Ejectors have been widely used in the field of heating, and also in the field of refrigeration, but are generally used in cold-only refrigerator systems. A single cooler system with an ejector, the ejector absorbs the refrigerant from the evaporator and directly sprays the refrigerant gas back to the compressor, and the system has fewer structural forms...
