Abstract
The utility model relates to a connecting structure of double compressors, which comprises a first compressor and a second compressor. A four-way reversing valve is arranged between the first compressor and the second compressor. The first exhaust pipe of the first compressor is communicated with the first interface of the four-way reversing valve; the fourth interface of the four-way reversing valve is communicated with the second retune pipe of the second compressor; the second exhaust pipe of the second compressor is communicated with a primary exhaust pipe; a primary return pipe is respectively communicated with the first return pipe of the first compressor and one end of a first connecting pipe; the other end of the first connecting pipe is communicated with the third interface of the four-way reversing valve; and the second interface of the four-way reversing is communicated with the primary exhaust pipe through a second connecting pipe. The first compressor and the second compressor are connected in parallel or in series to meet concrete requirements of a system in different working conditions through arranging the four-way reversing valve between the first compressor and the second compressor, arranging a switch valve on the primary exhaust pipe, and the direction shift of the four-way reversing valve and the switch of the switch valve.
Description
Technical field
The utility model relates to a kind of syndeton of double-compressor.
Background technology
The syndeton of double-compressor generally has in parallel and connects two kinds, the pressure reduction of compressor in parallel is little, the efficient height, as disclosing a kind of twin compressor room air conditioner among the Chinese patent literature CN 1414324A, by first, the second two compressor parallels are connected and comprise oil eliminator, outdoor heat exchanger, the throttling unit, in the refrigeration cycle of indoor heat exchanger and vapour liquid separator, it is characterized in that, the throttling unit that is located at the outdoor heat exchanger outlet is regulatable throttling unit, second exhaust outlet of compressor, first exhaust outlet of compressor is connected to the first and second decompression starting magnetic valves respectively and connects on the vapour liquid separator; First compressor, second exhaust outlet of compressor also are connected to oil eliminator by first, second check valve respectively, and oil eliminator also is connected with gas-liquid separator by decompression member; The return-air mouth of first compressor is communicated with the return-air mouth of second compressor, and the 3rd check valve is housed therebetween, and is connected with the outlet of vapour liquid separator.Compressors in series then can realize big pressure reduction, big temperature difference effect.But there is different requirements in system to the output of the system that is made up of double-compressor under different operating modes.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, be suitable for the orientation wide, easy to adjust, can be according to the concrete needs of system and the syndeton of the double-compressor of the annexation of timely adjustment double-compressor, to overcome weak point of the prior art.
Press the syndeton of a kind of double-compressor of this purpose design, comprise first compressor and second compressor, its architectural feature is to be provided with four-way change-over valve between first compressor and second compressor.
The downtake pipe of described first compressor communicates with first interface of four-way change-over valve, the 4th interface of four-way change-over valve communicates with second muffler of second compressor, the second exhaust pipe of second compressor communicates with main exhaust, main muffler communicates with first muffler of first compressor and the end of first communicating pipe respectively, the other end of first tube connector communicates with the 3rd interface of four-way change-over valve, and second interface of four-way change-over valve communicates with main exhaust by second tube connector.
Be provided with switch valve in described first tube connector.
Be provided with switch valve in described second tube connector.
The utility model is by being provided with four-way change-over valve between first compressor and second compressor, switch valve is set on main exhaust, by the direction switching of four-way change-over valve and the switching of switch valve, realize the in parallel and series connection of first compressor and second compressor, to satisfy the real needs of system under different operating modes.It has easy to adjust, advantage of wide range of application.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, the syndeton of this double-compressor comprises between first compressor 1 and second compressor, 2, the first compressors 1 and second compressor 2 being provided with four-way change-over valve 3.The downtake pipe 5 of first compressor 1 communicates with the first interface a of four-way change-over valve 3, the 4th interface d of four-way change-over valve 3 communicates with second muffler 6 of second compressor 2, the second exhaust pipe 11 of second compressor 2 communicates with main exhaust 8, main muffler 7 communicates with first muffler 9 and the end of first communicating pipe 10 of first compressor 1 respectively, the other end of first tube connector 10 communicates with the 3rd interface c of four-way change-over valve 3, and the second interface b of four-way change-over valve 3 communicates with main exhaust 8 by second tube connector 12.For better control, can in first tube connector 10 and second tube connector 12, be provided with switch valve 4.Provided the structure that is provided with switch valve 4 in second tube connector 12 among the figure.
When passing through four-way change-over valve 3, second muffler 6 of the downtake pipe 5 of first compressor 1 and second compressor 2 is communicated with, when first tube connector 10 is communicated with second tube connector 12, switch valve 4 cuts out, no flow of refrigerant in first tube connector 10 and second tube connector 12, first compressor 1 and second compressor 2 are for being connected in series.
When downtake pipe 5 that passes through four-way change-over valve 3, the first compressors 1 and 12 connections of second tube connector, second muffler 6 of second compressor 2 is communicated with first tube connector 10, and switch valve 4 is opened, and first compressor 1 and second compressor 2 are for being connected in parallel.
Above-mentioned is a kind of embodiment of the present utility model, only is used to illustrate the utility model, but not is used to limit the utility model.
