Abstract
The utility model discloses a multi-compressor refrigeration device, which comprises at least two compressors, and each air discharge pipe and each air suction pipe of the compressors. An air discharge main pipe and an air suction main pipe are respectively connected with the air discharge pipe and the air suction pipe of each compressor to cause the compressor to be connected in parallel. A condenser, a throttling set and an evaporator connected with an indoor air conditioning device are connected orderly between the air discharge main pipe and the air suction main pipe. An oil balancing pipe is arranged between the compressors. The interface of the oil balancing pipe and the compressors is lower than the height of the normal oil level in the compressors. The connecting mode omits a cross matching pipe and a decompression pipe which are arranged between the compressors. The multi-compressor refrigeration device can not only be directly processed in the factory, but also can be formed by simply modifying the existing compressor to obtain the effect that multiple compressors are connected in parallel. Therefore, the utility model has the characteristics of simple structure, convenient maintenance, low processing cost, reliable operation, etc.
Description
Technical field
The utility model belongs to air-conditioning equipment, relates in particular to a kind of multi-compressor refrigerator.
Background technology
At present, in air conditioner industry, adopt the situation of double-compressor more, regulate problem, Energy Efficiency Ratio is increased though this structure has solved the air conditioner refrigerating amount.But, since compressor when operation every compressor the oil return situation can not be identical, often a table oil position is high and another table oil position is low, is unfavorable for the operate as normal of compressor, the service life that so can reduce compressor for a long time.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy for installation, a kind of multi-compressor refrigerator that processing cost is low.
The utility model is achieved through the following technical solutions: a kind of multi-compressor refrigerator, comprise at least two compressors and blast pipe separately and air intake duct, exhaust main is connected with air intake duct with the blast pipe of every compressor respectively with air suction main and each compressor parallel is connected, the evaporimeter that is connected with condenser, throttling arrangement between exhaust main and the air suction main in turn and is connected with indoor air conditioner is provided with oil balance tube between compressor.
The interface of described oil balance tube and compressor is lower than the height of normal oil level in the compressor.
After adopting this structure,, when compressor separate unit or many operations, all can make the oil level in the compressor reach balance owing between every compressor, connect an oil balance tube.This connected mode has been saved intersection pipe arrangement and relief pipe between the compressor, both can directly process in factory, also existing compressor can be transformed simply, just can reach the effect of multiple compressors parallel connection.Therefore the utlity model has simple in structure, easy to maintenance, processing cost is low, characteristics such as reliable.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
The specific embodiment
Embodiment 1: as shown in Figure 1, multi-compressor refrigerator of the present utility model, include two compressors 6,7, compressor 6, be connected with oil balance tube 5 between 7, the interface of this oil balance tube 5 and compressor is lower than the height of normal oil level in the compressor, and double-compressor 6,7 are connected in parallel between exhaust main 8 and the air suction main 4, wherein exhaust main 8 respectively with compressor 6,7 blast pipe 8-1,8-2 links to each other, air suction main 4 respectively with compressor 6,7 blast pipe 4-1,4-2 links to each other, and is connected with condenser 1 in turn between exhaust main 8 and air suction main 4, throttling arrangement 2 and the evaporimeter 3 that is connected with indoor air conditioner.
Embodiment 2: as shown in Figure 2, the structure of the structure of present embodiment and embodiment 1 is basic identical, and its difference is that what present embodiment adopted is three compressors 6,7,9, between per two compressors oil balance tube 5 is housed all.
Can select the refrigerating capacity of separate unit compressor in application process according to overall refrigerating effect, the refrigerating capacity that several compressors are connected in parallel conforms to overall refrigerating effect.
Claims (2)
1, a kind of multi-compressor refrigerator, comprise at least two compressors and blast pipe separately and air intake duct, exhaust main is connected with air intake duct with the blast pipe of every compressor respectively with air suction main and each compressor parallel is connected, the evaporimeter that is connected with condenser, throttling arrangement between exhaust main and the air suction main in turn and is connected with indoor air conditioner is characterized in that: be provided with oil balance tube between compressor.
2, multi-compressor refrigerator according to claim 1 is characterized in that: the interface of described oil balance tube and compressor is lower than the height of normal oil level in the compressor.
