Abstract
The utility model relates to a large-scale air-cooled heat pump, in particular to a large-scale air-cooled heat pump with multiple parallel compressors, which comprises a plurality of groups of parallel compressor units formed by a plurality of compressors, the compressed gas outlet of each compressor (1) in each compressor unit is connected with the air inlet of an oil separator (2), the air outlet of oil separator (2) is connected with the air return orifice of each compressor (1). As the oil separators of a plurality of compressor units are parallel together, the utility model can make the compressor's refrigeration oil discharged along with the compressed gas renewedly return to the compressor in order to ensure the uniform oil return of each compressor in the refrigeration system and the reliable operation of each compressor in the refrigeration system, which thereby solves the problem of the oil return of the refrigeration oil and the key problem of the multiple parallel compressors. The utility model is a large-scale air-cooled heat pump which has the ingenious design, the low cost, the simple and convenient manufacture and the obvious refrigeration effect, and can make the heat pump unit more reliably and stably operate.
Description
Technical field
The utility model is a kind of large-sized wind cooling heat pump, and particularly a kind of large-sized wind cooling heat pump of multi-compressor parallel connection belongs to the renovation technique of large-sized wind cooling heat pump.
Background technology
At present, traditional large-sized wind cooling source pump adopts piston or helical-lobe compressor mostly, piston compressor is because bulky, complex structure is eliminated, helical-lobe compressor then generally uses, but helical-lobe compressor is when moving under the heat pump operating mode, the operating position very severe, need add complicated hydrojet cooling device, and reliability is not high; But screw compressor is applied in high-efficiency reliable operation under the heat pump operating mode, but cold is less usually.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of design ingenious, and is with low cost, makes simple and conveniently, and refrigeration is obvious, makes the large-sized wind cooling heat pump of the more reliable and stable operation of source pump.
Structural representation of the present utility model as shown in Figure 1, include some groups and the compressor bank that is formed in parallel by some compressors that connects, the outlet of the Compressed Gas of every compressor is connected with the air inlet of oil eliminator in each compressor bank, and the gas outlet of oil eliminator is connected with the return-air mouth of every compressor by cross valve.
Include 2～4 compressors in above-mentioned each compressor bank.
The above-mentioned compressor group includes 2～4 groups.
Connecting line between the return-air mouth of the outlet of above-mentioned cross valve and compressor is provided with the low pressure jar.
Be provided with total oil return capillary between the return-air mouth of above-mentioned each group compressor and the oil return opening of oil eliminator.
Be provided with branch oil return capillary between the return-air mouth of above-mentioned each compressor and the oil return opening of oil eliminator.
Above-mentioned compressor is a screw compressor.
The utility model adopts the structure include some groups and the compressor bank that is formed in parallel by some compressors that connects, the outlet of the Compressed Gas of every compressor is connected with the import of oil eliminator in each compressor bank, and the gas outlet of oil eliminator is connected with the return-air mouth of every compressor by cross valve.Because the oil eliminator of some compressor bank is connected in parallel, therefore, the refrigeration oil that compressor is discharged with Compressed Gas comes back in the compressor, guarantee the even oil return of every compressor in the refrigeration system, thereby all operations reliably of each compressor in the assurance refrigeration system, thereby solved the oil return problem of refrigeration oil, solved the key issue of multi-compressor parallel connection.The utility model is that a kind of design is ingenious, with low cost, makes simple and conveniently, and refrigeration is obvious, makes the large-sized wind cooling heat pump of the more reliable and stable operation of source pump.
