Specific embodiment
With reference to Figure of description and embodiment, specific embodiment of the present utility model is made further to retouch in detail
State.Following examples are merely to illustrate the utility model, but can not be used for limiting scope of the present utility model.
As shown in figure 1, air-conditioning system of the present utility model, including connect into the compressor 1 in loop, four-way valve 2, outdoor and change
Hot device 4, first throttle component 5 and indoor heat exchanger 10, it is described state air-conditioning system also include by electric expansion valve 6, fluid reservoir 7,
The auxiliary pipeline that the orifice union 9 of check valve 8 and second is sequentially connected in series, the auxiliary pipeline is parallel to outdoor heat exchanger in the main line
Pipeline between 4 outlet and the entrance of the indoor heat exchanger 10；Pressure sensor is provided with the main line of the air-conditioning system
3, for monitoring air-conditioning system pressure, the air-conditioning system is provided with controller (not shown), the controller respectively with temperature
Degree sensor 41 and electric expansion valve 8 are connected, the aperture for controlling electric expansion valve 6 according to the signal of temperature sensor, institute
The outlet mouth of pipe for stating fluid reservoir 7 is arranged at the bottom of fluid reservoir 7.
The control method of air-conditioning system of the present utility model, comprises the following steps：
When air-conditioner runs refrigeration mode, air-conditioning system pressure P is monitoredd, and judge air-conditioning system pressure PdWhether it is more than
The first preset pressure of system Pds1,
As air-conditioning system pressure PdThe first preset pressure of≤system Pds1When, controller control electric expansion valve 6 is closed, empty
Adjusting system is run by current state and continues to monitor system pressure；
As air-conditioning system pressure Pd>The first preset pressure of system Pds1When, controller controls electric expansion valve 6 to be opened with default
Degree is opened, and refrigerant enters fluid reservoir, is then exported through the efferent duct of fluid reservoir 7, after flowing through the orifice union 0 of check valve 8 and second
Heat exchanger is got in, and continues to monitor system pressure.
As the second preset pressure of system Pds2>=air-conditioning system pressure Pd>The first preset pressure of system Pds1When, controller control
Electric expansion valve processed 6 keeps current aperture, air-conditioning system to be run by current state and continue to monitor system pressure；
As air-conditioning system pressure Pd>The second preset pressure of system Pds2When, controller controls electric expansion valve 6 with default speed
Degree increase aperture, and continue to monitor system pressure.So circulation, according to system pressure PdRespectively with the preset pressure of system first
Pds1With the second preset pressure Pds2Compare, controller controls the aperture of electric expansion valve 6 to control entering for fluid reservoir inner refrigerant
Enter and export.
Wherein, the fluid reservoir can be according to the change adjustment storage of air-conditioning system pressure or the refrigerant amount of output.
In embodiment of the present utility model, during air-conditioning system operation refrigeration mode, the cyclic process of refrigerant is：Refrigeration
Agent is compressed through compressor 1, flows through four-way valve 2 and enters in outdoor heat exchanger 4 and exchanges heat, and is changed into after middle temperature high-pressure refrigerant through first
Orifice union 5 exchanges heat in getting in heat exchanger 10, and the refrigerant after heat exchange back flows back into 1 compression in compressor.When pressure is super
Cross preset pressure value Pds1When, controller controls electric expansion valve 6 to be opened with default aperture, and cold-producing medium stream is entered through electric expansion valve 6
Enter in fluid reservoir 7 that (wherein fluid reservoir inlet tube can not go deep into liquid storage tank body, and fluid reservoir outlet need to access liquid storage tank body bottom
Portion, to enable the refrigerant to output in time), then refrigerant gets in by after the throttling of 8 and second orifice union of individual event valve 9
Exchanged heat in heat exchanger 10,1 compression in compressor is back flowed back into after heat exchange.As the second preset pressure of system Pds2>=air-conditioning system pressure
Power Pd>The first preset pressure of system Pds1When, controller controls electric expansion valve 6 to increase aperture with pre-set velocity, makes more systems
Cryogen enters in fluid reservoir 7.When system pressure is again less than equal to preset pressure value Pds1When, controller control electric expansion valve 6
Close, the refrigerant stored in fluid reservoir is freezed in coming back to system through the second orifice union, and continue to monitor air-conditioning
System pressure, such loop control.
And then, scheduled time T is set before air-conditioning system brings into operation, it is necessary in controller0.Alternatively, make a reservation for
Time can be the Default Value of air-conditioning system, it is also possible to be set by User Defined.Thus, when the air-conditioning system system of bringing into operation
During chill formula, monitoring air-conditioning system pressure P is opened after the scheduled timed, and judge it with the preset pressure of system first and second
Preset pressure is compared, and controller controls the aperture of electric expansion valve 6 to control the into and out of fluid reservoir inner refrigerant.According to
Some specific embodiments of the present utility model, the span of the scheduled time can be 0s -60s, for example, the scheduled time can be with
It is 40s, by setting the scheduled time of 40s, rate of change when room temperature can be avoided to start to change is too big, makes air-conditioner to interior
The regulation of temperature is more gentle, so as to improve the comfort level of user to a certain extent.
Air-conditioning system provided by the utility model can control air-conditioning system to be stored up in high temperature when high-temperature refrigeration is carried out
Refrigerant is deposited, and the continuous control of cooling system agent flux and pressure is carried out according to the aperture of electric expansion valve, realize air-conditioning
