Abstract

The invention provides an air conditioner system which comprises a compressor, a four-way valve, an indoor heat exchanger, an outdoor heat exchanger, a gas-liquid separator and an ejector. A liquid outlet of the gas-liquid separator is connected with the outdoor heat exchanger through a fifth pipeline, the indoor heat exchanger is connected with a first inlet of the ejector through a sixth pipeline, the outdoor heat exchanger is connected with a second inlet of the ejector through a seventh pipeline, and an outlet of the ejector is connected with an input port of the gas-liquid separator through an eighth pipeline. By the adoption of the technical scheme, during heating, expansion work of a refrigerant is utilized through the ejector, the pressure of the air suction end of a compressor isimproved through the ejector, and the heating capacity and energy efficiency ratio of the air conditioner system in the low-temperature working conditions are improved, so that the requirements of theair conditioner system for the high load and the high pressure ratio are met, and the heating capacity and energy efficiency ratio of the air conditioner system in the low-temperature environment areimproved.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular to an air conditioning system. Background technique [0002] At present, the multi-connected system often uses two compressors or one air-supplementing enthalpy-enhancing compressor to meet the demand for heating capacity in low-temperature environments, such as outdoor environments with minus 15°C heating capacity without attenuation. [0003] However, when the outdoor ambient temperature is lower, the heating capacity and energy efficiency ratio of the air conditioning system will be greatly attenuated. In order to increase the low-temperature heating capacity and energy efficiency ratio of the unit, a compressor with a larger displacement and a larger high-to-low pressure ratio is required. However, the exhaust volume and high-low pressure ratio of the existing compressors are still limited, which makes it difficult to further improve the heating performa...
