Abstract
The utility model relates to a helical-lobe compressor, in particular to a refrigerating cycle system with the helical-lobe compressor. The refrigerating cycle system comprises the motor helical-lobe compressor, a condenser, a throttle valve and an evaporator, wherein the motor helical-lobe compressor, the condenser, the throttle valve and the evaporator are successively connected to constitute the refrigerating cycle system. The refrigerating cycle system mainly resolves the technical problems that an existing refrigerating cycle system with the helical-lobe compressor needs providing with an independent oil line system, system parts are added, and fault points are added. An extra lubricating oil system is not needed by the refrigerating cycle system, a lubricating oil separator, a circulation oil pump, a cooler, an oil box and the like are not needed, a the unit structure is greatly simplified, the unit size is reduced, and initial investment and operating cost are reduced.
Description
Technical field
The utility model relates to helical-lobe compressor, particularly a kind of cooling cycle system with helical-lobe compressor.
Background technology
Along with the attention of country to environmental protection and energy saving, more and more obvious to the trend of the future development of low energy consumption, compact conformation in the various kinds of equipment in industrial trade field.What freeze helical-lobe compressor is common equipment in the industrial trade.The helical-lobe compressor that adopts in the general kind of refrigeration cycle is fuel injection helical lobe compressor, for carrying out oil spout to the compressor compresses process, and guarantees the unit bearing is carried out fuel feeding, and unit generally all need be equipped with one and overlap independently oil piping system.This has also increased the trouble point simultaneously just for system has increased parts, has affected the reliability of entire system.
The utility model content
The purpose of this utility model is to provide a kind of cooling cycle system with helical-lobe compressor, mainly solving existing cooling cycle system with helical-lobe compressor all needs to be equipped with independently oil piping system, has not only increased system unit, but also has increased the trouble point technical problem, it need not to arrange extra lubricating oil system, saved oil separator, oil circulating pump, oil cooler, the equipment such as fuel tank, greatly simplify set structure, dwindled unit volume, reduced initial cost and operation cost.
For achieving the above object, the utility model is to realize like this.
A kind of cooling cycle system with helical-lobe compressor is characterized in that: it comprises motor screw compressor, condenser, choke valve and evaporimeter, and they are in turn connected into cooling cycle system by pipeline.
Described cooling cycle system with helical-lobe compressor is characterized in that: described choke valve export pipeline place establishes a bearing portion that is communicated to helical-lobe compressor in addition.
Described cooling cycle system with helical-lobe compressor is characterized in that: condenser is water cooled condenser or air cooled condenser.
Use the utility model system advantage compared with prior art to be.
1. the utility model system adopts SCREW COMPRESSOR, utilize the working medium that contains lubricating oil in the circulatory system that compressor drum and bearing are lubricated cooling, need not to arrange extra lubricating oil system, saved oil separator, oil circulating pump, oil cooler, the equipment such as fuel tank, greatly simplify set structure, dwindled unit volume, reduced initial cost and operation cost.
2. need not between the utility model system screw compression machine bearing and cavity complicated sealing device is set, simplified set structure, improved the stability of unit.
Description of drawings
Fig. 1 is the structural representation of the utility model one preferred embodiment.
Among the figure: 1-helical-lobe compressor, 2-motor, 3-bearing, 4-evaporimeter, 5-choke valve, 6-condenser.
The specific embodiment
See also Fig. 1, the utility model discloses a kind of cooling cycle system with helical-lobe compressor.As shown in the figure: it comprises motor 2 helical-lobe compressors 1, condenser 6, choke valve 5 and evaporimeter 4, and they are in turn connected into cooling cycle system by pipeline.Described condenser 6 is water cooled condenser or air cooled condenser.
The utility model system can select lower boilingly machine refrigerant working medium is arranged as working media in the system according to working condition, adds in working medium simultaneously that a small amount of lubricating oil is mobile in system with working medium preferably with the cold-producing medium intermiscibility.
During use, organic working medium is heated in evaporimeter 4, becomes the steam of low-temp low-pressure from the heating liquid of low-temp low-pressure, then enters the gas that helical-lobe compressor 1 is compressed into HTHP.Helical-lobe compressor 1 is driven by motor 2.In this process, the lubricating oil that mixes in the organic working medium is lubricated screw rotor when low temperature has the compression of machine refrigerant working medium.The HTHP working substance steam of discharging from helical-lobe compressor 1 enters condenser 4 condensations subsequently, and among this embodiment, condenser 6 selects to adopt water-cooled.After being condensed, enter choke valve 5 decrease temperature and pressure after the HTHP working substance steam liquefy, enter subsequently evaporimeter 6 and again heat, the circulation of finishing the work.
In addition, described choke valve 5 export pipeline places establish bearing 3 positions that are communicated to helical-lobe compressor 1 in addition, during use, the organic working medium that contain lubricating oil of part after choke valve 5 decrease temperature and pressure, before it enters evaporimeter 4, be introduced into the bearing 3 of helical-lobe compressor, bearing 3 is cooled off, lubricated.This part working medium enters helical-lobe compressor 1 cavity at bearing 3 positions after organic low boiling point refrigerant absorbing heat evaporation, and remaining lubricating oil can be used to bearing 3 is lubricated.Need not to arrange shaft seal between unit bearing 3 and compressor 1 cavity.
Being preferred embodiment of the present utility model only in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
