Abstract
The utility model relates to a double-compressor oil-level balancing device. The double-compressor is arranged between an air breathing main pipe and an air outlet main pipe in parallel. The air outlet main pipe is connected with the inlet of an oil extractor. One end of the oil inlet main pipe is connected with the oil drain outlet of the oil extractor. The oil inlet main pipe is provided with a decompressing main pipe. The other end of the oil inlet main pipe is connected with the air inlet of the air breathing main pipe. A piping and the relief pipe of the piping which are crossed are arranged between the double-compressor and an air inlet pipe of the double-compressor. The interface of the piping is arranged at the height of the normal oil level of the compressor. The oil-level balance of the double-compressor is realized by the crossing and connected pipes. The double-compressor oil-level balancing device has the advantages of simple structure, low cost and reliable operation to decrease the frequency of the compressor which is protected and to ensure the use effect of the air conditioner.
Description
The utility model relates to the double-compressor lubricant level equalising control device of air-conditioning equipment.
We know, fluorine Lyons gas dissolves the functional of lubricating oil, even design good compressor, also has some lubricating oil and is dissolved in the cold-producing medium, and along with exhaust enters the circulation line of air-conditioner, so when operation, must guarantee that the oil in the pipeline can return compressor.For air-conditioner, adopt oil eliminator to solve the oil return problem at present with double-compressor.But the oil return situation of two compressors is in operation can not be identical, and often a table oil position is high and another table oil position is low, is unfavorable for the operate as normal of double-compressor.As shown in Figure 1, in order to reach the oil level equilibrium of double-compressor, usually adopt two fuel level sensors to control, double- compressor 3,10 are connected in parallel between air suction main 5 and the exhaust main 2, exhaust main 2 connects oil eliminator 1, magnetic valve 6,7 are connected on the double-compressor oil inlet pipe in parallel, double-compressor 3, fuel level sensor 4 is installed respectively on 10,9,17 are the oil-feed house steward among Fig. 1,8 are the decompression house steward, rely on fuel level sensor 4,9 detect the oil level in each compressor, and control magnetic valve 6,7 open or close, to the compressor oil-feed of low oil level, make the oil level of double-compressor reach balanced.The major defect of its existence is: 1, circuit devcie is many, complex structure, and the cost height needs configuration two cover fuel level sensor and magnetic valves; 2, when compressor start or heating and defrosting, lubricating oil is not got back in the compressor temporarily in the pipeline, causes compressor frequently to be protected, and influences the result of use of air-conditioner; 3, increased the complexity of compressor control.
The purpose of this utility model is, overcomes the shortcoming of above-mentioned pair of fuel level sensor device, and a kind of simple in structure, double-compressor oil level balancer that cost is low, reliable is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of double-compressor oil level balancer, has oil eliminator, double-compressor, oil, the gas tube connector, double-compressor parallel is between air suction main and exhaust main, exhaust main is connected with the inlet of oil eliminator, oil-feed house steward one end is connected with the oil eliminator oil drain out, the oil-feed house steward goes up the decompression house steward is installed, it is characterized in that the oil-feed house steward other end is connected with the air suction main air inlet, have cross-coupled pipe arrangement and relief pipe thereof between double-compressor and its air inlet pipe, the pipe arrangement interface is positioned on the compressor normal oil level height.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 2 is the utility model general structure schematic diagram.
As shown in Figure 2, the utility model double-compressor oil level balancer has oil eliminator 1, double- compressor 3,10, oil, gas tube connector 17,2,5, double-compressor parallel is between air suction main 5 and exhaust main 2, exhaust main 2 is connected with the inlet of oil eliminator 1, oil-feed house steward 17 1 ends are connected with the oil drain out of oil eliminator 1, decompression house steward 8 is installed on the oil-feed house steward 17, the oil-feed house steward other end is connected with air suction main 5 air inlets, at double- compressor 3,10 with its air inlet pipe 51, has cross-coupled pipe arrangement 12 between 52,15 and relief pipe 14,13, the pipe arrangement 12 that is compressor 3 is connected with the air inlet pipe 52 of compressor 10 by relief pipe 14, the pipe arrangement 15 of compressor 10 is connected pipe arrangement interface 11 by relief pipe 13 with the air inlet pipe 51 of compressor 3,16 lay respectively at compressor 3, on 10 the normal oil level height.Dotted line is illustrated normal pasta position among the figure.
The utility model is realized the oil level equilibrium of double-compressor by cross-coupled pipe arrangement: when system moves, compressor 3,10 higher pressure refrigerant gas of discharging are isolated lubricating oil in oil eliminator 1, these lubricating oil flow into compressor air suction house steward 5 after 8 decompressions of the relief pipe on the oil-feed house steward 17, pass through compressor inleting pipe 51 again, 52 enter double-compressor, if the oil level in the compressor 3 is lower than normal oil level, only have a spot of higher pressure refrigerant gas by pipe arrangement 12 and on relief pipe 14 air inlet pipe 52 that enters another compressor 10, thereby enter in another compressor 10, little to the operate as normal influence of compressor; If when the oil level in the compressor 10 is higher than normal oil level, then in this compressor unnecessary lubricating oil will by pipe arrangement 15 and on relief pipe 13 flow into the air inlet pipe 51 of another compressors 3, thereby enter in another compressor 3, it is balanced that the oil level in double-compressor reaches.
Among the embodiment, the size of relief pipe comes by experiment to determine that its principle is to guarantee that certain flow of lubrication requires to make the negotiability of refrigerant gas as far as possible little down.
The utility model adopts common tube connector and relief pipe; reach the purpose of the balanced control of double-compressor oil level; simple in structure; cost is low, and is reliable, do not need to carry out signal controlling; reduced the complexity of electrical control; the reliability of what and compressor of compressor recirculating oil quantity can specifically be controlled by the choose reasonable relief pipe, and the protected frequency of compressor also will significantly reduce, thereby can guarantee the result of use of air-conditioner.
