Description
Technical field
The present invention relates to the accessory of air-conditioner, particularly relate to the gas-liquid separation device that is arranged on the cooler compressor air intake duct.
Background technology
Air-conditioner carries out heat exchange to realize room temperature lowering or intensification, for people provide comfortable live and work environment by the refrigerant and the indoor flow air that circulate in its refrigeration system.The refrigeration system of air-conditioner mainly is made up of heat exchanger, compressor and throttling device etc. as evaporimeter or condenser.In summer, the refrigerant in the refrigeration system carries out the refrigerating operaton that kind of refrigeration cycle realizes air-conditioner by the order of evaporation → compression → condensation → expansion; In the winter time, then by the switching of reversal valve, make refrigerant carry out the heating operation that reverse kind of refrigeration cycle realizes air-conditioner.
Compressor is the critical piece of air-conditioner refrigerating system, ensures that the refrigerant that carries out heat exchange in the refrigeration system circulates, and realizes the operation of air-conditioner circulation carrying out refrigerating/heating.Compressor is compressed into high-temperature high-pressure state from evaporimeter inspiration gaseous coolant and with it, again the HTHP gaseous coolant is sent into condenser, the HTHP gaseous coolant in condenser, carry out heat exchange with the external world and be cooled in the liquid of warm high pressure, the liquid coolant of the middle temperature high pressure that is come out by condenser becomes the low-temp low-pressure state and enters evaporimeter through throttling device decompression cooling, and the liquid refrigerants of low-temp low-pressure becomes the gas of low-temp low-pressure and carries out heat exchange with the external world under the negative pressure of evaporimeter.Then, the low-temp low-pressure gaseous coolant in the evaporimeter enters by compressor again and draws, is compressed into high-temperature high-pressure state in compressor, sends in the new kind of refrigeration cycle such as condenser.Compressor is as " heart " of air-conditioner, and its stable operation conditions helps the operate as normal running of air-conditioner.
Operating compressor is compressed into high-temperature high-pressure state by low pressure air suction pipe inspiration gaseous coolant, emits by the high pressure escape pipe again.Can not there be liquid to exist in the cold media gas of inspiration compressor, in order to avoid compressor generation liquid hammer damages its valve block.
In general, the cooler compressor air inlet connects gas-liquid separation device, comes the gaseous coolant of flash-pot to pass through gas-liquid separation device earlier, after the fluid separation applications in the refrigerant vapor is gone out, enters compressor again, in order to avoid the damage of compressor generation liquid hammer.
Fig. 1 is a cooler compressor of existing band gas-liquid separator.
As shown in Figure 1, the cooler compressor gas-liquid separator is made of the cylindrical shell that inside forms certain space, and the two ends up and down of cylindrical shell form small-bore round mouth, and housing upper end round mouth connects the refrigerant inlet pipe, the wireway in the round mouth stationary housing of housing lower end.Wireway and screen pack are set in the housing.Wireway is the L shaped pipe of top end opening, and top stands upright in the cylindrical shell, and the bottom is bent and is fixed on the round mouth of housing lower end from housing lower end round mouth.Screen pack is arranged on the top in the housing, is fixed on the cross section vertical with the housing cylinder by fixed head.The refrigerant inlet pipe of gas-liquid separator housing upper end connects evaporimeter, bends the wireway that from gas-liquid separator housing lower end round mouth and is communicated with compressor suction duct.
Come the gaseous coolant that contains drop of flash-pot, the refrigerant inlet pipe that connects from gas-liquid separator housing upper end enters in the gas-liquid separator, and passes screen pack and realize gas-liquid separation.The refrigerant drop is by the screen pack collection of condensing, and flows down along screen pack and housing post jamb, is collected at the bottom in the gas-liquid separator cylindrical shell; Cold media gas behind the precipitation of liquid droplets enters in the pipe from the opening on wireway top, enters compressor by compressor suction duct again, is compressed into the gaseous coolant of HTHP in compressor.Gas-liquid separator makes the gaseous coolant that contains drop of flash-pot to realize gas-liquid separation, prevents that the drop in the refrigerant vapor from entering compressor, to avoid the liquid hammer damage of compressor.
But, the gas-liquid separator for compressor of above-mentioned prior art adopts the screen pack that is fixed in the housing by fixed head to carry out gas-liquid separation, complex structure, particularly, on the enclosure interior cross section vertical, fixed head is set and screen pack has higher specification requirement with cylinder, cause existing gas-liquid separator manufacturing process complexity, the cost height.
Summary of the invention
The present invention is directed to the existing problem of gas-liquid separator for compressor of prior art, employing is inner not to be provided with screen pack and to have the simplified structure of air inlet in the wireway upper end, so that make the gas-liquid separator simplified manufacturing technique, reduces production costs.
Gas-liquid separator for compressor involved in the present invention is made of the cylindrical shell that inside forms certain space, wireway is set in the housing, the two ends up and down of housing form small-bore round mouth, and housing upper end round mouth connects the refrigerant inlet pipe, the wireway in the round mouth stationary housing of housing lower end.Wireway is L shaped pipe, and top stands upright in the cylindrical shell and is elongated to the top of housing, and the bottom is bent and is fixed on the round mouth of housing lower end from housing lower end round mouth.The wireway top closure, there is gas port the upper end, and gas port is the aperture that is distributed on the wireway upper side tube wall.The refrigerant inlet pipe of gas-liquid separator housing upper end connects evaporimeter, bends the wireway that from gas-liquid separator housing lower end round mouth and is communicated with compressor suction duct.
Come the gaseous coolant that contains drop of flash-pot, the refrigerant inlet pipe that connects from gas-liquid separator housing upper end enters in the gas-liquid separator, the refrigerant drop flows down along the housing post jamb, be collected at the bottom in the gas-liquid separator cylindrical shell, cold media gas enters in the pipe from the gas port of wireway upper end, enters compressor by compressor suction duct again.Gas-liquid separator makes the gaseous coolant that contains drop of flash-pot to realize gas-liquid separation, prevents that the drop in the refrigerant vapor from entering compressor, to avoid the liquid hammer damage of compressor.
Gas-liquid separator for compressor involved in the present invention is simple in structure, has simplified manufacturing process, has reduced production cost.
