Abstract
The invention relates to a distributive air conditioner oil return method. When two or more than two compressors run at the same time, refrigeration oil separated by an oil separator is respectively transferred to an oil inlet pipe through a distributor and then enters the compressors through an air intake pipe. When some compressors run and others stop, because the air intake pipe is arranged vertically, the oil entering the compressors which are in the halted state returns to the distributor under the action of gravity and then enters the compressors which are in the running state. The invention can improve the work efficiency and ensure the safe running of the compressors.
Description
Technical field
The present invention relates to a kind of distributive air conditioner oil return method.
Background technology
Compressor gas-liquid pipeline in the VRF Air Conditioning System, be used to two or two above compressors conveying gas-liquids, comprise respectively and two or two air intake ducts that above compressor links to each other, and the distributor that links to each other with air intake duct, and be arranged on oil inlet pipe between distributor and the compressor, that be used for transferring oil, reach appendix that link to each other with distributor, that be used to carry gas.Yet existing compressor gas-liquid pipeline is not provided with distributor, can not effectively be assigned to compressor; And air intake duct does not all have vertically to be provided with yet, if only move the part compressor, enters into the oil that does not move compressor and still can stay this compressor, causes the waste of oil, inefficiency; Simultaneously, can not guarantee the safe operation of compressor.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of can increasing work efficiency, and can guarantee the distributive air conditioner oil return method of compressor safe operation.The present invention is achieved through the following technical solutions:
A kind of distributive air conditioner oil return method of the present invention, this compressor gas-liquid pipeline comprises respectively and two or two air intake ducts that above compressor links to each other, and the distributor that links to each other with air intake duct, and be arranged on oil inlet pipe between distributor and the compressor, and the appendix that links to each other with distributor, and the distributor that links to each other with oil inlet pipe, and the oil eliminator that links to each other with distributor, described air intake duct vertically is provided with; This method of work is: when two or two above compressors moved simultaneously, the refrigeration oil of oil eliminator being separated by distributor was transported to respectively in the oil inlet pipe, enters into compressor by air intake duct again; When the part compressor operating, when another part compressor stops, because described air intake duct vertically is provided with, the oil that enters into the halted state compressor is under the effect of gravity, get back to distributor, and then enter into the compressor of running status, guarantee the safe operation of compressor.
As preferably, described distributor comprises outlet and inlet, and described air intake duct links to each other with the outlet of distributor, and described appendix links to each other with the inlet of distributor.
Distributive air conditioner oil return method of the present invention owing to be provided with oil eliminator and distributor, when compressor moves simultaneously, is got back to corresponding compressor from the refrigeration oil that oil eliminator comes out separately; When the part compressor operating, when another part compressor stops, because described air intake duct vertically is provided with, the oil that enters into the halted state compressor is under the effect of gravity, get back to distributor, and then entering into the compressor of running status, it can be increased work efficiency, and guarantees the safe operation of compressor.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the schematic diagram of distributive air conditioner oil return method of the present invention.
The specific embodiment
As shown in Figure 1, a kind of distributive air conditioner oil return method of the present invention, be used to two or two above compressor A and B to carry gas-liquid, comprise respectively and two or two air intake ducts 1 that above compressor A links to each other with B, and the distributor 2 that links to each other with air intake duct 1, and be arranged on oil inlet pipe 3 between distributor 2 and the compressor, that be used for transferring oil, and 2 that link to each other with distributor, as to be used to carry gas appendix 4, described air intake duct 1 vertically is provided with.Also comprise the distributor 5 that links to each other with oil inlet pipe 3, and the oil eliminator 6 that links to each other with distributor 5, when two or two above compressors moved simultaneously, the refrigeration oil of oil eliminator 6 being separated by distributor 5 was transported to respectively in the oil inlet pipe 3, enters into compressor by air intake duct 1 again; When part compressor A operation, when another part compressor B stops, the oil that enters into halted state compressor B is under the effect of gravity, can get back to distributor 2 along the wall of air intake duct 1, and then enter into the compressor A of running status, it can be increased work efficiency, and guarantees the safe operation of compressor.
Wherein, described distributor 2 comprises outlet 20 and inlet 21, and described air intake duct 1 links to each other with the outlet 20 of distributor, and described appendix 4 links to each other with the inlet 21 of distributor.
Distributive air conditioner oil return method of the present invention owing to be provided with oil eliminator and distributor, when two compressors move simultaneously, is got back to corresponding compressor from the refrigeration oil that separator comes out separately; When the part compressor operating, when another part compressor stops, because described air intake duct vertically is provided with, the oil that enters into the halted state compressor is under the effect of gravity, get back to distributor, and then entering into the compressor of running status, it can be increased work efficiency, and guarantees the safe operation of compressor.
The foregoing description, just an example of the present invention is not to be used for limiting enforcement of the present invention and interest field, the identical or technical scheme that is equal to of the described content of claim all and of the present invention all should be included in the protection domain of the present invention.
