Problems solved by technology

However, in the low temperature state, due to factors such as relatively low evaporation temperature and easy frosting of the evaporator, the heat absorbed by the refrigerant from the air is greatly reduced, and the heating effect becomes poor, which affects the user's use effect and often causes customer complaints.
[0003] Therefore, how to design an air-conditioning system to improve the insufficient heat exchange capacity of the air-conditioning system due to low temperature has become a technical problem to be solved urgently.

Embodiment 1

[0054] Such as figure 1 As shown, when it is cold in winter, the user turns on the air conditioner and adjusts the air conditioner to the heating mode. At this time, the first valve port m is connected to the second valve port n, and the fourth valve port p is connected to the third valve port o. , the exhaust from the compressor 102 enters the four-way valve from the first valve port m, then flows out from the second valve port n, reaches the indoor heat exchanger 116 to condense and release heat, and then enters the flash evaporator through the second interface b pipe of the flash evaporator 104 104 , the refrigerant is separated into gas and liquid, and the separated gaseous refrigerant flows out from the third interface c of the flasher 104 and is injected into the compressor 102 to enhance the injection effect of the compressor and improve the overall capacity of the compressor 102 . At the same time, the separated liquid refrigerant is divided into two paths, one path is...

Embodiment 2

[0058] Such as figure 2 As shown, in the heating mode, based on the first embodiment, the liquid refrigerant coming out of the fourth port of the flash evaporator is throttled by the second throttling device 110, and then reaches the auxiliary heat exchanger 112, where it evaporates and absorbs heat to become a gaseous refrigerant, and then It directly reaches the outlet of the gas-liquid separator 118, flows into the compressor together with the refrigerant separated by the gas-liquid separator, and is finally absorbed and compressed by the compressor 102 to complete the heating cycle.

[0059] Similarly, in combination with Embodiment 1, in the refrigeration mode, the liquid refrigerant coming out of the fourth port of the flash evaporator is throttled by the second throttling device 110, and then enters the auxiliary heat exchanger after being throttled by the second throttling device 110 112, further cooling the refrigerant in the main flow, evaporating and absorbing heat...

Abstract

The invention provides an air conditioning system and an air conditioner. The air conditioning system comprises a compressor, a four-way valve, an indoor heat exchanger, an outdoor heat exchanger and a throttling device, wherein a first valve port of the four-way valve is connected to the compressor, a second valve port of the four-way valve is connected to the indoor heat exchanger, and a third valve port of the four-way valve is connected to the outdoor heat exchanger. The air conditioning system further comprises an auxiliary heat exchanger and a flash evaporator, wherein the auxiliary heat exchanger is connected to the outdoor heat exchanger, and the flash evaporator is connected to the auxiliary heat exchanger and the compressor. According to the technical scheme, the enhanced vapor injection effect is improved, the supercooling degree of the system is improved, the heat exchange ability of a unit is improved, the problem that the heat exchange ability of the air conditioning system is poor because of low temperature is solved, and therefore the heat exchange effect of the whole air conditioning system is improved.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to an air conditioning system and an air conditioner. Background technique [0002] With the improvement of people's living standards and the enhancement of energy-saving awareness, air-conditioners have entered the vast number of ordinary families and have been more and more widely used due to their energy-saving, flexible control, and easy installation and maintenance. However, in the low temperature state, due to factors such as low evaporation temperature and easy frosting of the evaporator, the heat absorbed by the refrigerant from the air is greatly reduced, and the heating effect is deteriorated, which affects the user's use effect and often causes customer complaints. [0003] Therefore, how to design an air-conditioning system to improve the insufficient heat exchange capacity of the air-conditioning system due to low temperature has become a technical ...
