Description
Technical field
The present invention relates to a kind of gas-liquid separator of heat pump, particularly a kind of gas-liquid separator for heat pump that adopts the siphon mode oil return.
Background technology
In the present existing heat pump, all include compressor, cross valve, condenser, expansion valve, evaporimeter.In process of refrigerastion, after entering the air side heat exchanger heat exchange by cross valve, the gaseous refrigerant of compressed machine pressurization lowers the temperature, become the liquid state of low-temp low-pressure again by the expansion valve step-down, enter again and become the low pressure gaseous state after the water-side heat evaporation and be inhaled in the compressor by cross valve.In the process of heating, after entering the water-side heat heat release by cross valve, the gaseous refrigerant of compressed machine pressurization lowers the temperature, heated medium is heated up, become the liquid state of low-temp low-pressure again by the expansion valve step-down, enter again and become the low pressure gaseous state after the air side heat exchanger evaporation heat absorption and be inhaled in the compressor by cross valve.For fear of refrigeration or heat and have a small amount of not liquid refrigerant of gasification to enter in the process in the compressor liquid hit phenomenon to take place and influence the compressor life-span and state of cyclic operation is worsened, generally between compressor and cross valve, all gas-liquid separator to be housed, make back the cold-producing medium of compressor be introduced into gas-liquid separator, at this liquid refrigerant of not vaporization is separated, only allow gaseous refrigerant and lubricating oil enter compressor.Present gas-liquid separator technology adopts centrifugal separation allow gas-liquid separation mostly, but does not allow the less amount of lubrication oil in the liquid enter in the compressor.
Summary of the invention
The objective of the invention is to overcome above-mentioned prior art deficiency, a kind of gas-liquid separator for heat pump that adopts the siphon mode oil return is provided, this gas-liquid separator can effectively be separated in the gas-liquid separator of the cold-producing medium under the various operating modes in heat pump, and can lubricating oil be got back in the compressor with gaseous refrigerant by siphon.
Gas-liquid separator of the present invention is installed between the evaporimeter and compressor in the heat pump.
Technical scheme of the present invention is achieved in that the cylindrical shell, the top that the present invention includes seamless steel pipe and the make gaseous refrigerant muffler that is connected with vertical direction that has end socket, cylindrical shell central inner to install back gas bushing, return-air sleeve pipe top, the tangential direction at cylindrical shell middle part are welded with the air inlet sleeve pipe, the air inlet sleeve pipe connects air inlet pipe, the cylindrical shell bottom is welded with base, the return-air internal surface of sleeve pipe is welded with low level oil return pipe and high-order oil return pipe, low level oil return pipe and high-order oil return pipe pipe end all stretch out the inwall end opening, and the low level oil return pipe is lower than 1/5～1/4 of the about pipe range of high-order oil return pipe.
The position of air inlet pipe is higher than the bottom of return-air sleeve pipe.
The cylindrical shell bottom is bowl-shape.
The low level oil return pipe is identical with high-order oil return pipe two length of tube, and the pipe end otch of low level oil return pipe and high-order oil return pipe is ∠ θ=15 °～45 ° with the vertical direction angle all in the return-air sleeve pipe.
The material of low level oil return pipe, high-order oil return pipe is a copper tube.
The present invention adds oil return pipe by the gas-liquid separator that uses in heat pump increase the oil return measure, not only can prevent the liquid hammer of compressor, the lubricating oil of carrying under one's arms in the cold-producing medium is entered in the compressor, reduce the delivery temperature of compressor, increase the service life of compressor, improved the reliability of system and the ability of cooling and warming.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a vertical view of the present invention;
Below in conjunction with accompanying drawing content of the present invention is described in further detail.
The specific embodiment
With reference to Fig. 1, shown in Figure 2, cylindrical shell 1, the top that the present invention is made by seamless steel pipe has end socket 2, cylindrical shell 1 central inner to install back that gas bushing 3, return-air sleeve pipe 3 tops are connected with the gaseous refrigerant muffler 4 of vertical direction, the tangential direction at cylindrical shell 1 middle part is welded with air inlet sleeve pipe 7, air inlet sleeve pipe 7 connects air inlet pipe 8, cylindrical shell 1 bottom is welded with base 9, return-air sleeve pipe 3 inwalls are welded with low level oil return pipe 5 and high-order oil return pipe 6, low level oil return pipe 5 and high-order oil return pipe 6 pipe ends all stretch out the inwall end opening, and low level oil return pipe 5 is lower than 1/5～1/4 of high-order oil return pipe 6 about pipe ranges.The position of air inlet pipe 8 is higher than the bottom of return-air sleeve pipe 3.6 liang of length of tube of low level oil return pipe 5 and high-order oil return pipe are identical, and the pipe end otch of low level oil return pipe 5 and high-order oil return pipe 6 is ∠ θ=15 °～45 ° with the vertical direction angle all in return-air sleeve pipe 3.The material of low level oil return pipe 5 and high-order oil return pipe 6 is a copper tube.
During work, the gas that comes out through evaporator outlet, the liquid mix refrigerant enters the disengagement chamber of gas-liquid separator from the tangential direction of cylindrical shell 1 by gas-liquid mixed refrigerant inlet tube 8 and air inlet sleeve pipe 7, screw takes place, make liquid refrigerant be rotated down and flow into bowl-shape bottom along cylindrical shell 1 inwall by centrifugal action, gaseous refrigerant then is inhaled in the compressor by the return-air sleeve pipe 3 cooled via return air pipes 4 at center.
When the liquid level of bottom rises, because it is lighter that liquid refrigerant contains the proportion of lubricating oil and lubricating oil, float on the liquid refrigerant liquid level, when liquid level rises to the bottom of low level oil return pipe 5, because the pressure during compressor air suction in the return-air sleeve pipe 3 is very low, the pressure of cylindrical shell 1 is very high, then just by siphonage, the lubricating oil on the liquid refrigerant liquid level is sucked low level oil return pipe 5 be inhaled in the compressor by the return-air sleeve pipe 3 cooled via return air pipes 4 at center.When liquid level continues to rise to the bottom of high-order oil return pipe 6, because the pressure in the return-air sleeve pipe 3 is very low, the pressure of cylindrical shell 1 is very high, then, the lubricating oil on the liquid refrigerant liquid level is sucked high-order oil return pipe 6 be inhaled in the compressor by the return-air sleeve pipe 3 cooled via return air pipes 4 at center more just by siphonage.Gas and lubricating oil can both be got back in the compressor after so just making the cold-producing medium of gas-liquid mixed by gas-liquid separator.
