Abstract
The utility model discloses a double-compressor parallel structure. The double-compressor parallel structure comprises an inverter compressor and a frequency fixed compressor which are connected in parallel. One end of the inverter compressor and one end of the frequency fixed compressor are connected with an exhaust pipe through an oil separator connected with the inverter compressor and the frequency fixed compressor, the other end of inverter compressor and the other end of the frequency fixed compressor are connected with a gas-liquid separator through gas returning pipes, a pressure-sharing oil- balancing pipe is arranged on the upper portions of the gas returning pipes, the oil separator is connected with the gas returning pipes through a capillary pipe, and the pressure-sharing oil- balancing pipe is a horizontal pipe arranged between the gas returning pipes which are connected with the inverter compressor and the frequency fixed compressor respectively. Due to the fact that the pressure-sharing oil- balancing pipe is arranged on the upper portions of the gas returning pipes, in the use process of an air conditioner and a heat pump water heater, the pressure of returned gas is even, returned oil is even, the running is reliable and safe, the service life is longer, and the defects that due to the facts that the rotating speed of the frequency fixed compressor is constant, and the rotating speed of the inverter compressor is changeable, the pressure of returned gas is uneven, the returned oil is uneven, and the compressors are severely damaged due to oil losses after long-time running.
Description
Technical field
The utility model relates to double-compressor parallel structure field, relates in particular to a kind of double-compressor parallel structure for air-conditioning, heat pump.
Background technology
Common double compressor parallel scheme is that invariable frequency compressor and frequency-changeable compressor are in parallel, and the frequency-changeable compressor variable speed due to invariable frequency compressor invariablenes turning speed causes that back pressure is uneven, oil return is uneven, after long-play compressor because of oil starvation badly damaged.
Utility model content
The utility model embodiment technical problem to be solved is, provides that a kind of back pressure is even, oil return is even, the double-compressor parallel structure of reliable safety, long service life.
Described double-compressor parallel structure, comprise the frequency-changeable compressor and the invariable frequency compressor that are connected in parallel, one end of described frequency-changeable compressor and invariable frequency compressor is all connected with blast pipe by connected oil eliminator, the other end is connected with gas-liquid separator by muffler, described muffler top is provided with all presses oil equalizing pipe, and described oil eliminator is connected by capillary with described muffler.
The described oil equalizing pipe of all pressing is the horizontal tube being arranged between the muffler being connected with described frequency-changeable compressor and invariable frequency compressor respectively.
Implement the utility model embodiment, there is following beneficial effect:
The utility model embodiment double-compressor parallel structure is being provided with and is all pressing oil equalizing pipe with the frequency-changeable compressor being connected parallel with one another and invariable frequency compressor muffler top, make air-conditioning, Teat pump boiler in use back pressure be even, oil return is even, reliable safety, longer service life, avoided the frequency-changeable compressor variable speed due to invariable frequency compressor invariablenes turning speed, cause that back pressure is uneven, oil return is uneven, after long-play compressor because of oil starvation badly damaged.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model embodiment double-compressor parallel structure, comprise the frequency-changeable compressor 1 and the invariable frequency compressor 2 that are connected in parallel, one end of frequency-changeable compressor 1 and invariable frequency compressor 2 is all connected with blast pipe 4 by connected oil eliminator 3, the other end is connected with gas-liquid separator 6 by muffler 5, muffler 5 tops are provided with and all press oil equalizing pipe 7, oil eliminator 3 is connected by capillary 8 with muffler 5, all press oil equalizing pipe 7 for being arranged on the horizontal metal pipe between the muffler being connected with frequency-changeable compressor and invariable frequency compressor respectively, the utility model embodiment double-compressor parallel structure is being provided with and is all pressing oil equalizing pipe with the frequency-changeable compressor being connected parallel with one another and invariable frequency compressor muffler top, make air-conditioning, Teat pump boiler in use back pressure is even, oil return is even, reliable safety, longer service life, avoided the frequency-changeable compressor variable speed due to invariable frequency compressor invariablenes turning speed, cause back pressure uneven, oil return is uneven, after long-play compressor because of oil starvation badly damaged.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
