Abstract
The utility model discloses a kind of open-type helical-lobe compressor Parallel sets, including many open-type being connected in parallel helical-lobe compressors, every open-type helical-lobe compressor is connected by valve member with oil cooler, every open-type helical-lobe compressor is connected by valve member with oil eliminator, is connected between the oil eliminator and oil cooler by valve member；Many opened compressor parallel connections of the utility model, can be using ammonia as refrigerant.And separate unit head can realize energy adjustment, the energy adjustment of wider range can be achieved in many parallel connections, and especially in underrun, there is higher refrigerating efficiency relative to using the big opened compressor of separate unit, even if single compressor breaks down, other several may continue to work, and multiple compressors share oil eliminator, an oil cooler, reduce the charging amount of refrigeration oil simultaneously, cost is reduced, compact conformation reduces unit framework, floor space is reduced, investment is reduced.
Description
Technical field
The utility model belongs to technical field of refrigeration equipment, and in particular to a kind of open-type helical-lobe compressor Parallel sets.
Background technology
Opened compressor refrigeration plant is freezed using single compressor mostly at this stage, and this Refrigeration Technique is present
Defect be：1. energy adjustment can not be carried out on a large scale, in underrun, refrigerating efficiency is low；If 2. compressor goes out
Existing failure, a whole set of refrigeration plant can not work on.
Therefore we have developed a kind of open-type helical-lobe compressor Parallel sets, this equipment by many opened compressors simultaneously
Connection.
Open-type helical-lobe compressor can use environmental protection refrigerant ammonia.Ammonia is as extremely environmentally friendly refrigerant, its ODP (ozone
Destructing index) it is that 0, GWP (greenhouse effects index) is 0, produce easily, it is cheap.
Separate unit head can realize energy adjustment, and the energy adjustment of wider range can be achieved in many parallel connections.And especially low negative
When lotus runs, there is higher refrigerating efficiency relative to using the big opened compressor of separate unit.Even if there is event in single compressor
Barrier, other several may continue to work.
Multiple compressors share oil eliminator, an oil cooler, while reducing the charging amount of refrigeration oil, reduce and make
Valency, compact conformation reduces unit framework, reduces floor space.
Utility model content
The utility model provides a kind of open-type helical-lobe compressor Parallel sets to solve Problems Existing.
The technical solution of the utility model is：
A kind of open-type helical-lobe compressor Parallel sets, including many open-type helical-lobe compressors being connected in parallel, it is described
Every open-type helical-lobe compressor is connected by valve member with oil cooler, and every open-type helical-lobe compressor passes through valve
Door component is connected with oil eliminator, is connected between the oil eliminator and oil cooler by valve member.Open-type screw rod can make
With and be not limited to ammonia as refrigerant.Ammonia is as extremely environmentally friendly refrigerant, and its ODP (ozone layer destroying index) is 0, GWP (greenhouses
Effect index) it is 0, produce easily, it is cheap.
It is further preferred that setting Stress control table on every open-type helical-lobe compressor.
It is further preferred that setting suction filter before every open-type helical-lobe compressor.
It is further preferred that setting gradually oily stream on the pipeline that every open-type helical-lobe compressor is connected with oil cooler
Amount switch, liquid-sighting glass and liquid filter.
The beneficial effects of the utility model are：
1. the utility model multiple compressors are in parallel, and separate unit head can realize energy adjustment, and many parallel connections can be achieved more
The energy adjustment of wide scope, and especially in underrun, it is higher relative to being had using the big opened compressor of separate unit
Refrigerating efficiency.
2. many open-type helical-lobe compressors of the utility model are connected in parallel, even if single compressor breaks down, other
Several may continue to work.
3. the utility model multiple compressors share oil eliminator, an oil cooler, while reducing filling for refrigeration oil
Fluence, reduces cost.
4. the utility model compact conformation, reduces unit framework, floor space is reduced, investment is reduced.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model open-type helical-lobe compressor Parallel sets；
Wherein：1. for open-type helical-lobe compressor；2 be oil eliminator；3 be oil cooler；4 be suction filter；5 be liquid
Body filter；6 be liquid-sighting glass；7 be oily flow switch.

Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this practicality
It is new, it is not used to limit the utility model.
Below in conjunction with the accompanying drawings and specific embodiment is further described to application principle of the present utility model.
Embodiment 1, such as Fig. 1, a kind of open-type helical-lobe compressor Parallel sets, including many open-type spiral shells being connected in parallel
Bar compressor 1, every open-type helical-lobe compressor 1 is connected by valve member with oil cooler 3, every open-type
Helical-lobe compressor 1 is connected by valve member with oil eliminator 2, and valve member is passed through between the oil eliminator 2 and oil cooler 3
Connection.
It is further preferred that setting suction filter 4 before every open-type helical-lobe compressor 1.
It is further preferred that setting gradually oil on the pipeline that every open-type helical-lobe compressor 1 is connected with oil cooler 3
Flow switch 7, liquid-sighting glass 6 and liquid filter 5.
Many opened compressor parallel connections of the utility model, and separate unit head can realize energy adjustment, many parallel connections can be real
The energy adjustment of existing wider range, has higher refrigerating efficiency relative to using the big helical-lobe compressor of separate unit.
Many open-type helical-lobe compressors of the utility model are connected in parallel, even if single compressor breaks down, other are several
Platform may continue to work.
The utility model multiple compressors share oil eliminator, an oil cooler, while reducing the filling of refrigeration oil
Amount, reduces cost.
The utility model compact conformation, reduces unit framework, reduces floor space.
Embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for
For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former
