Air conditioning system

Abstract

The invention belongs to the technical field of air conditioners and particularly relates to an air conditioning system. In order to effectively improve cooling / heating effect of an air conditioner and reduce energy consumption, the air conditioning system comprises a compressor, an outdoor heat exchanger, an indoor heat exchanger, an auxiliary heat exchanger and an ejector; the compressor, the outdoor heat exchanger, the auxiliary heat exchanger, the indoor heat exchanger and the ejector form a coolant cycle main loop; the compressor, the outdoor heat exchanger / indoor heat exchanger, the auxiliary heat exchanger and the ejector form a coolant cycle branch loop; in cooling / heating cycle, part of a coolant from the compressor flows into the ejector along the main loop, the other part of thecoolant flows into the ejector along the branch loop, and the two parts of the coolant are mixed in the ejector before the mixture reflows into the compressor. The auxiliary heat exchanger is used toimprove the supercooling effect of the coolant; the ejector is used to increase the suction pressure of the compressor, arriving at pressure increasing and efficiency improving; the cooling effect ofthe air conditioner in a high temperature environment and the heating effect thereof in a low temperature environment are improved, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner system. Background technique [0002] Existing air conditioner systems usually form a refrigeration / heating cycle loop by a condenser, throttling device, evaporator, and compressor. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor is condensed into a low-temperature and high-pressure liquid in the condenser, and is throttled The device is throttling into a low-temperature and low-pressure liquid, and then enters the evaporator to absorb heat and evaporate to complete a refrigeration / heating cycle. [0003] The traditional air conditioner system has poor heating effect in low-temperature environment and cooling effect in high-temperature environment, and has high energy consumption, which cannot achieve the purpose of energy saving and high efficiency. Some air conditioner systems use enthalpy-increa...

Problems solved by technology

[0003] The traditional air conditioner system has poor heating effect in low-temperature environment and cooling effect in high-temperature environment, and has high energy consumption, which cannot achieve energy-saving and high-efficiency goals.

Some air conditioner systems use enthalpy-increasing compressors to achieve the purpose of boosting and increasing efficiency, but due to the complicated manufacturing and high cost of compressors, it is not conducive to replacement and maintenance
