Referring to fig. 1, according to an embodiment of the present application, an air conditioning system is provided.
Specifically, the air conditioning system includes a compressor 10, a condenser 20, a flash tank 30, an evaporator 40, and an air tank 50. The inlet end of the condenser 20 communicates with the outlet end of the compressor 10. The inlet end of the flash tank 30 communicates with the outlet end of the condenser 20. The inlet end of the evaporator 40 communicates with a first outlet end of the flash tank 30, and the outlet end of the evaporator 40 communicates with the inlet end of the compressor 10. An inlet end of the air tank 50 communicates with a second outlet end of the flash tank 30, and an outlet end of the air tank 50 communicates with at least one of an inlet end of the compressor 10 and an inlet end of the evaporator 40.
In this embodiment, after the air conditioning system is started, the air storage tank 50 provides a medium-pressure refrigerant to the compressor, and the liquid refrigerant with a lower enthalpy enters the evaporator for heat exchange and then enters the compressor for compression with the medium-pressure refrigerant, so that the refrigeration capacity of the air conditioning system at the starting stage can be increased, and the effect of rapid refrigeration of the air conditioning system is achieved.
When the air conditioning system is not turned on, the air storage tank 50 is in a medium pressure state, and the compressor 10, the condenser 20, the flash tank 30 and the evaporator 40 are all in a low pressure state. With the arrangement, when the air conditioning system is started, the medium-pressure refrigerant in the air storage tank 50 can smoothly enter the compressor. When the air conditioning system is switched from the off state to the on state and operates for a first preset time, the air storage tank 50 is communicated with the compressor 10, the air storage tank 50 supplies refrigerant to the compressor 10, after the first preset time, the air storage tank 50 is disconnected from the compressor 10, and the air storage tank 50 stops supplying refrigerant to the compressor 10.
Preferably, the outlet end of the air tank 50 communicates with the inlet end of the compressor 10, and the air conditioning system further includes a first check valve 61 and a second check valve 62. A first one-way valve 61 is provided in the line between the second outlet port of the flash tank 30 and the inlet port of the air reservoir 50. The second check valve 62 is provided on a pipe where an outlet end of the air tank 50 communicates with an inlet end of the compressor 10. The arrangement can facilitate the storage of the medium-pressure refrigerant in the air storage tank 50 and the transportation of the refrigerant in the air storage tank 50 to the compressor.
The air conditioning system is switched from a shutdown state to a startup state, and the first check valve 61 is in a closed state and the second check valve 62 is in an open state within a first preset time of operation. After a first preset time of operation, the first check valve 61 is in an open state and the second check valve 62 is in a closed state. After the pressure within the air reservoir 50 reaches the intermediate pressure state after the second preset has been run, the first check valve 61 is in the closed state. And every time the air conditioning system is switched from the off state to the on state, the second check valve 62 is in the open state, and the first check valve 61 is in the closed state. The arrangement of the air storage tank 50 for supplying the medium-pressure refrigerant to the compressor can effectively improve the refrigerating speed of the air conditioning system.
To further improve the energy efficiency of the air conditioning system, the air conditioning system further comprises a first throttle valve 71, a second throttle valve 72 and a third throttle valve 73. The first throttle valve 71 is disposed on a pipeline where the outlet end of the air tank 50 communicates with the inlet end of the compressor 10, and the first throttle valve 71 is located between the second check valve 62 and the compressor. A second throttle valve 72 is provided in the line communicating between the outlet of the condenser 20 and the inlet of the flash tank 30. A third throttle valve 73 is provided in the line communicating between the first outlet end of the flash tank 30 and the inlet end of the evaporator 40.
The air conditioning system in the above embodiment may also be used in the technical field of air conditioning equipment, that is, according to another aspect of the present invention, an air conditioner is provided. The air conditioning system is the air conditioning system in the embodiment.
Specifically, as shown in fig. 1, the air conditioning system includes a compressor, a condenser, a throttle valve, an evaporator, a flash tank, an air tank 50, a check valve, and the like. When the air conditioning system is not started, the air storage tank 50 is in a medium-pressure state, and other components are in a low-pressure state. The first check valve 61 and the second check valve 62 are in a closed state where the air tank 50 is not communicated with the outside. When the compressor is started, the first check valve 61 is kept closed, the second check valve 62 is opened, and medium-pressure gas in the gas storage tank 50 enters the low-pressure suction end of the compressor through the second check valve 62 and the first throttling valve 71, so that the flow of refrigerant in the starting stage is increased, and the refrigerating capacity is improved. After the valve is opened for a certain period of time, the pressure in the air storage tank 50 is reduced, the first check valve 61 is opened, and the second check valve 62 is closed. The refrigerant is compressed into high-pressure gas by the compressor 10, cooled into high-pressure liquid by the condenser 20, and then throttled into a medium-pressure gas-liquid mixture by the second throttle valve 72 to enter the flash tank 30, so that the gaseous refrigerant in the flash tank 30 is medium-pressure and higher than the pressure in the gas storage tank 50, and therefore part of the gaseous refrigerant enters the gas storage tank 50 through the first check valve 61 to be stored. The liquid refrigerant in the flash tank is throttled for the second time by the third throttle valve 73 to be a low-pressure gas-liquid mixture, and the low-pressure gas-liquid mixture enters the evaporator, is absorbed by the compressor after being absorbed in the evaporator, and then enters the next cycle. Because the gaseous refrigerant with higher enthalpy enters the gas storage tank 50, the liquid refrigerant with lower enthalpy in the flash evaporator enters the evaporator through secondary throttling, so that the heat exchange capacity of the evaporator is improved, and the effect of rapid refrigeration is realized. Because the second check valve 62 that the gas holder 50 is connected has not opened yet this moment, along with the gaseous refrigerant that flows into the gas holder 50 is more and more, pressure in the gas holder 50 can constantly rise until reaching the middling pressure after, the gaseous refrigerant in the flash tank no longer flows into the gas holder 50, and quick refrigeration is ended this moment. The first check valve 61 is then closed and the gas pressure within the reservoir 50 returns to the medium pressure condition at start-up, and resumes operation until the next start-up.
