Description of drawings
Accompanying drawing 1 is the structural scheme of mechanism of the gas-liquid separator of a kind of carbon dioxide heat pump system use of the present invention.
In the above accompanying drawing: 1, gas-liquid two-phase import; 2, gas vent; 3, liquid outlet; 4, regenerator import; 5, electric expansion valve; 6, sealed shell of tank; 7, dividing plate with holes; 8, defroster; 9, safety valve; 10, charging valve.
The specific embodiment
The invention will be further described below in conjunction with embodiment shown in the drawings.
Embodiment one: shown in accompanying drawing 1.
The gas-liquid separator that a kind of carbon dioxide heat pump system uses is applied in the carbon dioxide heat pump system.This gas-liquid separator comprises sealed shell of tank 6, is provided with the dividing plate with holes 7 for dredging flow, balanced seal tank body 6 internal pressures in the sealed shell of tank 6.Dividing plate 7 with holes comprises plate body, offers several manholes on the plate body.Dividing plate 7 with holes is separated into the upper and lower with the inner space of sealed shell of tank 6.Top is provided with gas-liquid two-phase import 1 and is connected with the gas-liquid two-phase inlet pipe, and the other end of gas-liquid two-phase inlet pipe is connected with evaporimeter in the carbon dioxide heat pump system.The top of bottom is provided with gas vent 2 and is connected with escape pipe, and this escape pipe passes dividing plate 7 with holes and top by the bottom and by the Base top contact of sealed shell of tank 6.The bottom of bottom is provided with liquid outlet 3 and is connected with drain pipe, is provided with control valve on the drain pipe, and this control valve is electric expansion valve 5.Drain pipe forms regenerator import 4 with the tandem of escape pipe phase and is connected with regenerator in the carbon dioxide heat pump system behind control valve.Gas vent 2 and liquid outlet 3 are provided with filter screen, and this screen pack can effectively filter and purification of carbon dioxide (gas, liquid) and lubricating oil.The tank wall of sealed shell of tank 6 is provided with defroster 8.Defroster 8 is the electric heated defrosting device, and it is coated on the tank wall of sealed shell of tank corresponding to bottom 6.Be provided with on sealed shell of tank 6 corresponding to the top of sealed shell of tank 6 and fill mouthful and be connected with charging valve 10, also be provided with safety valve 9 on sealed shell of tank 6 corresponding to the top of sealed shell of tank 6.
When carbon dioxide heat pump system is worked, carbon dioxide coolant is entered in the sealed shell of tank 6 by gas-liquid two-phase import 1, after the shunting and buffering through dividing plate 7 with holes, atmospheric carbon dioxide enters regenerator import 4 through the gas vent 2 that is provided with filter screen and enters in the regenerator; The liquid CO 2 that settles down and lubricating oil are deposited on the bottom of sealed shell of tank 6, discharge by the liquid outlet 3 that is provided with filter screen.Electric expansion valve 5 is installed on the drain pipe, aperture by certain control and feedback signal adjusting electric expansion valve 5, and liquid CO 2 and lubricating oil are inputted in the regenerators by regenerator import 4, by regulating the effectively control system degree of superheat of electric expansion valve 5, the suction temperature of regulating compressor.
When this gas-liquid separator moves in low temperature environment, easily frosting on its sealed shell of tank 6.When frost layer acquires a certain degree, also have more liquid carbon dioxide deposition in the gas-liquid separator, the gaseous carbon dioxide that this moment, compressor sucked reduces, and heating capacity reduces, and COP descends.Start defroster 8 this moment, can effectively prevent sealed shell of tank 6 surperficial frostings, improve simultaneously the gas concentration lwevel of sealed shell of tank 6 inside, when compressor air suction end carbon dioxide is not enough, give and replenish, namely increase the gas concentration lwevel of compressor air suction mouth, the elevator system performance.
Filled mouthful on the sealed shell of tank 6 is used for filling all required carbon dioxide coolants of carbon dioxide heat pump system operation, fill mouth by arranging on this gas-liquid separator surface, can effectively avoid at miscellaneous part or pipeline the uneven and security of system hidden danger of pressure that filled mouth brings being set.
Above-mentioned gas-liquid separator has solved the gas, liquid of carbon dioxide heat pump system, separation and the purification filtering problem of oil, the defrost performance of assisted carbon dioxide heat pump system, and along with the variation real-time control system oil return of system condition with return liquid, the control system degree of superheat, improve the systematic function of carbon dioxide heat-pump, promoted the heating efficiency of carbon dioxide heat-pump at the low temperature extremely frigid zones.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
