Abstract
The oil separator with mounted heater includes a cylindrical main body, a tangent inlet in the upper part of the main body, a refrigerant outlet in the top center of the main body; a lubricant oil outlet in the bottom center of the main body, and a heater in the inlet. The heater is one electric heater mounted around the inlet. The present invention adds one heater to a common oil separator, and in condition of outdoor temperature lowered to below -20 deg C in winter, the heater is used in heating the mixture of refrigerant and oil flowing from the compressor to the oil separator to facilitat e the separation of lubricant oil from the refrigerant, avoid reverse separation and ensure the normal operation of the air conditioner.
Description
Technical field
The present invention relates to a kind of oil eliminator, particularly relate to a kind of oil eliminator that is arranged on compressor outlet place in the air-conditioner outdoor unit and heater is installed on it.
Background technology
Usually, air-conditioner is a kind of device that makes its inner refrigerant carry out the kind of refrigeration cycle be made up of compression process, condensation process, expansion process and evaporation process.In air-conditioner, the refrigerant that becomes high-temperature high-pressure state through overcompression can dispel the heat to the outside in condenser, and when flowing through expansion valve, significantly reducing its temperature and pressure, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter then, flow back to compressor at last again.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioner, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.Fig. 1 is compressor and an oil eliminator connection status schematic diagram in the air-conditioner outdoor unit of prior art.Fig. 2 is the oil separator structure schematic diagram among Fig. 1.As Fig. 1, shown in Figure 2, all be connected with an oil eliminator 2 at the outlet place of every compressor 1, the refrigerant that is compressed into the HTHP gaseous state by the compression mechanical portion in the compressor 1 will enter body 3 from the inlet 4 that is positioned at drum shape body 3 top tangent to periphery directions on the oil eliminator 2 with the parts of lubricating oil in the compressor 1, lubricating oil will be rotated downwards along the inner circumferential of body 3 under the effect of centrifugal force and deadweight and flow to the lubricating oil outlet 5 of body 3 bottom centre then, at last flow through capillary 6 and get back to the inside of compressor 1 along lubricating oil pipeline, gaseous coolant then with after the lubricating oil separation enters circulation line from the refrigerant exit 7 that is positioned at body 3 top center, again flow back to receiver 8 through behind the indoor set at last, and in receiver 8, isolate liquid refrigerants, inlet from compressor 1 enters its inside then, thereby finishes once circulation.But, because this oil eliminator 2 is arranged in the air-conditioner outdoor unit, when winter, outdoor temperature dropped to below-20 ℃, the refrigerant that enters oil eliminator will sink because of lubricating oil viscosity becomes big former thereby change, thereby make it be difficult for being separated from each other with lubricating oil, contrary segregation phenomenon promptly occurs, can influence the normal operation of air-conditioner so undoubtedly.
Summary of the invention
In order to address the above problem, even the object of the present invention is to provide a kind of oil eliminator that heater is installed that also can make refrigerant and lubricating oil be easy to separate in the winter of cold.
In order to achieve the above object, the oil eliminator that heater is installed provided by the invention comprises a drum shape body; Be arranged on the inlet of body top tangent to periphery direction; Be positioned at the refrigerant exit at bodies top center; Be positioned at the lubricating oil outlet of body bottom centre; With a heater that is installed in the porch.
Described heater is arranged on the exterior periphery of inlet.
Described heater is an electric heater.
The oil eliminator that heater is installed provided by the invention is in the porch of conventional oil separator a heater to be installed, when winter, outdoor temperature dropped to below-20 ℃, can utilize this heater to heat and flow to the refrigerant of oil eliminator and the mixture of lubricating oil by compressor outlet, thereby the refrigerant that flows into oil eliminator is easy to and lubricating oil separation, therefore can prevent contrary segregation phenomenon, and can guarantee that air-conditioner normally moves.
Description of drawings
Below in conjunction with the drawings and specific embodiments the oil eliminator that heater is installed provided by the invention is elaborated.The parts identical with prior art use identical symbol, and omit its explanation of carrying out.
Fig. 1 is compressor and an oil eliminator connection status schematic diagram in the air-conditioner outdoor unit of prior art.
Fig. 2 is the oil separator structure schematic diagram among Fig. 1.
Fig. 3 is the oil separator structure schematic diagram that heater is installed provided by the invention.
The specific embodiment
As shown in Figure 3, the oil eliminator 10 that heater is installed provided by the invention is arranged on the exit of compressor 1 in the air-conditioner outdoor unit, comprises a drum shape body 3; Be arranged on the inlet 4 of body 3 top tangent to periphery directions; Be positioned at the refrigerant exit 7 of body 3 top center; Be positioned at the lubricating oil outlet 5 of body 3 bottom centre; With a heater 11 that is installed in inlet 4 places.Described heater 11 is arranged on the exterior periphery of inlet 4, refrigerant and lubricating oil are heated evenly, and heater 11 is an electric heater.When winter, outdoor temperature dropped to below-20 ℃ and the user want to heat circulation time, it can press the heater button that is arranged on the remote controller when starting air-conditioner, at this moment, the heater 11 that is arranged on oil eliminator 10 inlets 4 exterior periphery will be connected power supply, thereby the generation heat, thereby can will flow to the mixture heating of the refrigerant and the lubricating oil of oil eliminator 10 from compressor 1 outlet by heat conducting mode.When the lubricating oil temperature in this mixture rises, its viscosity descends thereupon, thereby in oil eliminator 10, can under the effect of centrifugal force and gravity, successfully be separated from each other with refrigerant, thereby the normal contrary segregation phenomenon of moving of air-conditioner can not appear influencing, therefore can improve the performance and the reliability of air-conditioner.
