As shown in figure 5, a kind of Gas-supplying enthalpy-increasing heat pump type air conditioning system using described bidirectional screw flash vessel, including tonifying Qi
Enthalpy-increasing compressor 101, four-way valve 102, outdoor heat exchanger 103, indoor heat exchanger 107, gas-liquid separator 108, its feature
It is：Also include bidirectional screw flash vessel, the escaping pipe 2 of the bidirectional screw flash vessel is sequentially connected magnetic valve by pipeline
109 and the gas supplementing opening of Gas-supplying enthalpy-increasing compressor 101, the first refrigerant inlet/outlet pipe 3 of the bidirectional screw flash vessel is by pipe
Road is sequentially connected the first electric expansion valve 104 and outdoor heat exchanger 103, and the second refrigerant of the bidirectional screw flash vessel enters
Outlet 4 is sequentially connected the second electric expansion valve 106 and indoor heat exchanger 107 by pipeline.
The Gas-supplying enthalpy-increasing heat pump type air conditioning system of the present embodiment, the switching of refrigerating/heating pattern is carried out by four-way valve 102.
When refrigeration mode runs, high-temperature high-pressure refrigerant enters into outdoor heat exchanger 103 from Gas-supplying enthalpy-increasing compressor 101, passes through
First electric expansion valve 104 carries out one-level throttling, then flows into bidirectional screw flash vessel 105.Gas-liquid mixed refrigerant is in flash distillation
In device after flash distillation, gaseous refrigerant carries out tonifying Qi to Gas-supplying enthalpy-increasing compressor 101 via tonifying Qi pipeline, and liquid refrigerant passes through
The two-step throttle of second electric expansion valve 106 gets in the evaporation endothermic of side heat exchanger 107, then flows back to Gas-supplying enthalpy-increasing compressor
101.Heating mode operational process is similar, refers to Fig. 5.
As a result of the flash vessel with two-way flow function, thus Gas-supplying enthalpy-increasing system diagram is greatly simplified.In low temperature
Heat, high-temperature refrigeration etc. needs to carry out the operating mode of tonifying Qi, the gaseous refrigerant that bidirectional screw flash vessel 105 is flashed off is via electromagnetism
Valve 109 carries out tonifying Qi to Gas-supplying enthalpy-increasing compressor 101.When heat pump type air conditioning system operates in the operating mode for not needing tonifying Qi, the first electricity
The standard-sized sheet of sub- expansion valve 104, magnetic valve 109 is closed.Now bidirectional screw flash vessel 105 is filled as liquid storage and used, liquid refrigerant
By entering the evaporation endothermic of indoor heat exchanger 107 after the throttling of the second electric expansion valve 106.
When heat pump type air conditioning system operates in refrigeration mode, gas-liquid two-phase cold-producing medium is entered from the first refrigerant inlet/outlet pipe 3
Enter, part mix refrigerant can flow out in the first oil return hole for back flow 31, and due to the very fast remaining hybrid refrigeration of refrigerant flow rates
Agent is flowed up along spiral copper pipe.Gas-liquid two-phase mix refrigerant flows in spiral copper pipe can produce centrifugal force, inertia force
Less gaseous refrigerant is gathered in the inner side of spiral copper pipe, and the larger liquid refrigerant of inertia force is gathered in outside spiral copper pipe
Side.Part gaseous refrigerant after centrifugal force separate flows out from first venthole 32 at angle on interior skew back, some liquid refrigerant
Flowed out from the first fluid hole 33 of outer skew back inferior horn.Manage interior residue mix refrigerant from the end of the first refrigerant inlet/outlet pipe 3
Spray, gas-liquid separation is carried out under gravity.The gaseous refrigerant isolated and the gaseous refrigerant for flashing off are via gas
Liquid sorting hole 51 and escaping pipe 2 carry out tonifying Qi to Gas-supplying enthalpy-increasing compressor 101.And the liquid refrigerant isolated is from the second oil return
Hole for back flow 41 flows out, and flowing into indoor heat exchanger 107 again by the two-step throttle of the second electric expansion valve 106 is evaporated heat absorption.
So the effect of the last gas-liquid separation of bidirectional screw flash vessel 105 is double effectses of the centrifugal force separate plus Gravity Separation,
Can improve and ensure the separation degree of gas-liquid refrigerant in flash vessel, and then ensure the job security of compressor.
When heat pump type air conditioning system operates in heating mode, gas-liquid two-phase mix refrigerant is from second refrigerant inlet/outlet pipe
4 enter, and the mix refrigerant of high speed flows up along spiral copper pipe, and under the influence of centrifugal force, gaseous refrigerant is from second
Venthole 42 flows out, and liquid refrigerant flows out from the second fluid hole 43.Residue mix refrigerant is passed in and out from second refrigerant in pipe
Mouth pipe 4 end is sprayed, and gas-liquid separation is carried out under gravity.The gaseous refrigerant for separating and flashing off flows from escaping pipe 2
Go out carries out tonifying Qi to Gas-supplying enthalpy-increasing compressor 101, and liquid phase refrigerant flows out from the first oil return hole for back flow 31, via the first electronics
Then the second throttle of expansion valve 104 is flowed into outdoor heat exchanger 103 and is evaporated heat absorption.
As can be seen that the heat pump type air conditioning system that the present embodiment is provided can not only improve the separation effect of the connected refrigerant of gas-liquid
Really, the heat exchange efficiency of system is improved, and solves the limitation of existing flash vessel one-way flow, greatly simplify the knot of system
Structure complexity, is especially suitable for setting height(from bottom) and is limited, highly with the less application scenario of diameter ratio.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention
Implementation method restriction.For those of ordinary skill in the field, can also make on the basis of the above description
The change or variation of other multi-forms.There is no need and unable to be exhaustive to all of implementation method.It is all of the invention
Any modification, equivalent and improvement made within spirit and principle etc., should be included in the protection of the claims in the present invention
