Abstract
The utility model relates to an oil balancing device between compressors in an air conditioner, which comprises a plurality of compressors and pipes connected with the compressors. A copper pipe is used for mutually connecting oil passages in oil balance pipes in parallel between the compressors. The compressors are pairwise connected in parallel by the copper pipe, and then compressor units are connected in parallel for realizing the communication of gas balance pipes, wherein, the oil balance pipe between the compressor 1 and the compressor 2 is provided with a one-way valve which is connected with a capillary pipe in parallel. Compared with the prior art, the utility model has the advantages of fewer adopted components, clear and brief pipes and simple and easy connection. The oil balancing device is only added with one assembly which is composed of the one-way valve and the capillary pipe which are connected in parallel, and thus oil balance is realized between compressors with lower fuel level and other compressors.
Description
Technical field
The utility model relates to a kind of air conditioner in the refrigerating field, the oil balance tube line structure between when being meant compressor parallel in this air conditioner especially.
Background technology
At present rarely seen on market have a large power air-conditioned machine that adopts the multiple compressors parallel connection.A key point utilizing this technology is the equilibrium that how to guarantee the pressure and the oil level of compressor chamber, conventional method is with each compressor parallel with a copper pipe, be communicated with the oil level that principle reaches balance automatically to long for according to liquid level, but under the operating mode of compressor parallel, owing to be stressed and the influence of other various factors, the variation of the inner oil level of each compressor is comparatively complicated, is difficult to reach consistent.The external report that correlation technique was once arranged, but control mode more complicated, China's ZL00240625.X patent " double-compressor oil level balancer " discloses a solution, with double-compressor parallel 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, the oil-feed house steward other end is connected with the air suction main air inlet, between double-compressor and its air inlet pipe, have cross-coupled pipe arrangement and relief pipe thereof, the pipe arrangement interface is positioned on the compressor normal oil level height, also promptly realize the oil level equilibrium of double-compressor by cross-coupled pipe arrangement, it is comparatively complicated that its annexation still seems, the process and assemble program is many, the technological requirement height.
Summary of the invention
The purpose of this utility model provides simple, the practical syndeton of the compressor chamber in parallel of constructed effect at oily balance that but can reach of a kind of annexation.
Designed compressor chamber oil balancer in a kind of air conditioner according to above-mentioned purpose, comprised multiple compressors and connected pipeline, made the oil balance tube road realize mutual oil circuit parallel connection by a copper pipe between the compressor; By the connection that realizes the gas equalizing line in parallel between group again after copper pipe one group of parallel connection in twos, wherein the oil balance tube road between compressor 1 and the compressor 2 is provided with a check valve between the compressor, and this check valve also with one section capillary paralleling.
The utility model compared with prior art, the employing parts are few, the pipeline simple and clear, connect easily simply, only in the most basic pipeline, increase the compressor that an assembly of being made up of check valve and capillary paralleling can realize that oil level is lower and the oily balance of other compressor chamber.
Description of drawings
Specific embodiments
In the utility model, whole parallel-connection structure couples together the compressor air suction place by a gas balance pipe, so that compressor return air pressure is in poised state substantially, concrete connected mode is that a pair of compressor such as compressor 1,2 are one group, 3,4 is that one group of elder generation is together in parallel by a gas balance pipe 51,52 respectively, be communicated with by a gas balance pipe again between the compressor bank, promptly be unified for 5 times, see shown in the accompanying drawing 1 a house steward.Add a common copper pipe 6 then as oil balance tube, under the constant situation of each compressor load, can make pasta relatively more balanced.But when compressor load changes, the fluctuation that pressure of inspiration(Pi) is not also stopping, pasta is to be difficult to complete equipilibrium by a common copper pipe like this, so the mode that the utility model takes to add at the lower compressor oil balance pipe place of oil level an assembly that is composed in parallel by check valve 7 and capillary 8 addresses this problem.During assembling, carry out Performance Match and regulate internal diameter capillaceous and length according to different models and power with this, can control the difference between the oil mass that the oil mass that enters compressor and compressor flow out, with this oil mass of the low compressor of original oil level is constantly replenished, thereby make compressor in oil level operation reliably.
Claims (2)
1, compressor chamber oil balancer in a kind of air conditioner comprises multiple compressors and connected pipeline, makes the oil balance tube road realize mutual oil circuit parallel connection by a copper pipe between the compressor; By the connection that realizes the gas equalizing line in parallel between group again after copper pipe one group of parallel connection in twos, it is characterized in that the oil balance tube road between compressor (1) and the compressor (2) is provided with a check valve (7) between the compressor.
2, compressor chamber oil balancer according to claim 1 is characterized in that described check valve (7) is in parallel with one section capillary (8).
