Problems solved by technology

[0002] In the current air-conditioning system, in the low-temperature heating environment, the economizer usually uses the technology of injecting refrigerant to increase the enthalpy to increase the circulation of the refrigerant, thereby improving the heating capacity of the air-conditioning system. The control of the opening of the valve body for the amount of refrigerant is generally positively correlated with the degree of superheat of the exhaust gas, that is, the greater the degree of superheat of the exhaust gas, the greater the opening of the valve body. The problem that the amount of refrigerant in the machine is reduced and the superheat of the exhaust gas is increased instead

Embodiment 1

[0065] Such as Figure 1 to Figure 5 As shown, the present invention provides an air conditioning system 500 , including: a compressor 510 , an outdoor heat exchanger 520 , an economizer 540 , a first valve 550 , a second valve 560 , a memory 570 and a processor 580 .

[0066] Specifically, such as figure 1 and figure 2 As shown, the outdoor heat exchanger 520 communicates with the inlet port 512 of the compressor 510, the economizer 540 includes a first outlet 542 and a second outlet 544, the first outlet 542 communicates with the outdoor heat exchanger 520, and the economizer 540 The second outlet 544 communicates with the compressor 510; the first valve 550 is located between the first outlet 542 and the outdoor heat exchanger 520, and is configured to adjust the amount of refrigerant flowing into the outdoor heat exchanger 520 through the economizer 540 ; The second valve 560 is configured to be suitable for connecting or blocking the refrigerant passage between the eco...

Embodiment 2

[0074] Such as Figure 1 to Figure 5 As shown, in the air conditioning system 500 provided by the present invention, on the basis of the first embodiment above, the processor 580 is further configured to execute a computer program to realize: In this case, control the first valve 550 to increase the opening degree; based on the fact that the exhaust superheat degree is equal to the exhaust superheat degree threshold, control the first valve 550 to maintain the current opening degree.

[0075] In this embodiment, on the one hand, when the degree of superheat of the exhaust gas is less than the threshold value of the degree of superheat of the exhaust gas, the pressure at the second outlet 544 of the economizer 540 is reduced by controlling the first valve 550 to increase the opening degree, and then Reducing the amount of refrigerant flowing into the compressor 510 through the second outlet 544 of the economizer 540 is conducive to quickly increasing the superheat of the exhaus...

Embodiment 3

[0082] Such as Figure 1 to Figure 5 As shown, the air conditioning system 500 provided by the present invention, on the basis of the above-mentioned embodiment 2, further, the preset opening range includes the first preset opening range, the second preset opening range and the third preset opening range. degree interval, the processor 580 executes the computer program to realize the step of controlling the first valve 550 to increase the opening degree according to the working speed, or controlling the first valve 550 to reduce the opening degree according to the working speed, including: based on the opening degree to which the current opening degree belongs When the interval is the first preset opening interval, the first valve 550 is controlled to increase the opening according to the first speed threshold, or the first valve 550 is controlled to decrease the opening according to the first speed threshold; based on the opening to which the current opening belongs When the ...

Abstract

The invention provides an air conditioning system, a control method of the air conditioning system and a computer readable storage medium. The air conditioning system comprises a compressor, an outdoor heat exchanger, an economizer, a first valve, a second valve, a storage and a processor, a first outlet of the economizer communicates with the outdoor heat exchanger, a second outlet communicates with the compressor, the first valve is configured to adjust the quantity of a refrigerant flowing into the outdoor heat exchanger through the economizer, the second valve is configured to communicate or be disconnected with a refrigerant passage between the economizer and the compressor, and the processor is configured to be used for executing a computer program so as to achieve the effects that based on a heating mode, the second valve communicates with the refrigerant passage between the economizer and the compressor to obtain the exhaust superheat degree, and based on the situation that the exhaust superheat degree is larger than the exhaust superheat degree threshold value, the first valve is controlled to reduce the opening degree. According to the air conditioning system, when the exhaust superheat degree is larger than the exhaust superheat degree threshold value, the opening degree of the first valve is reduced, a large number of refrigerants rapidly flow into the compressor through the economizer, and the exhaust superheat degree is reduced.
