Description
Technical field
The present invention relates to a kind of multipurpose Condensing units, belong to technical field of refrigeration equipment.
Background technology
Condensing units form kind of refrigeration cycle by parts such as condenser, choke valve, evaporator and multiple compressors
System.Present Condensing units manufacturing cost is high, and utilization rate is low, can only freezing and refrigeration or low-temperature quick-freezing, function is single.
The content of the invention
Object of the present invention is to provide a kind of multipurpose Condensing units, it can realize single stage compress in parallel and double
Level compression, can freezing and refrigeration and can low-temperature quick-freezing, can carry out multiplexing energy multi-state multipurpose work, be manufactured into so as to save
This, improves utilization rate.
To reach above-mentioned purpose, the technical scheme is that：A kind of multipurpose Condensing units, including an evaporation
Device, the evaporator are connected to the first compressor, the second compressor, the 3rd compressor, first compressor, the second compression
Machine, the 3rd compressor parallel are set, and first compressor, the second compressor, the 3rd compressor are also all connected with condenser, are condensed
Device is also connected with heat exchanger, first throttle valve in turn, and first throttle valve is connected with evaporator, is pressed in the second compressor and the 3rd
Three-way diverter valve and first check-valve are set between contracting machine, the inlet end of the 3rd compressor is provided with second check-valve, cold
Magnetic valve, second throttle are provided between condenser and heat exchanger；One outlet side of the three-way diverter valve and the first non-return
Valve is connected, and another outlet side is connected with the air entry and heat exchanger 11 of the 3rd compressor respectively；3rd compressor is height
Arbitrarily downgrade compressor.
The beneficial effects of the invention are as follows：The present invention can realize single stage compress in parallel and series connection Two-stage Compression, make the present invention both
Freezing and refrigeration can be used for and can be used for low-temperature quick-freezing again, the utilization rate of equipment is improved, so as to reduce cost.Described twin-stage pressure
Contraction SAPMAC method, refer to the refrigerant for carrying out flash-pot, after low-pressure stage compressor and the second compression of high pressure stage compressor two,
Just enter condenser, its height arbitrarily downgrades compressor cylinder quantity or volumetric ratio is generally 1/3 or so, as compressor air-discharging amount is identical
It is arranged in parallel using three compressors, can also uses two different compressors of compressor air-discharging amount or multiple compressors combination to set
Put, low-pressure stage compressor air-discharging amount is slightly larger, and high pressure stage compressor capacity is slightly smaller, its high-low pressure compressor cylinder quantity or
Volumetric ratio is generally 1: 3 capacity.
Brief description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in figure 1, a kind of multipurpose Condensing units, including an evaporator 1, the evaporator 1 are connected to
First compressor 2, the second compressor 3, the 3rd compressor 4, first compressor 2, the second compressor 3, the 3rd compressor 4 are in parallel
Set, first compressor 2, the second compressor 3, the 3rd compressor 4 are also all connected with condenser 8, and condenser 8 is also sequentially connected
There are heat exchanger 11, first throttle valve 12, first throttle valve 12 is connected with evaporator 1, in the second compressor 3 and the 3rd compressor
Three-way diverter valve 5 and first check-valve 6 are set between 4, the inlet end of the 3rd compressor 4 is provided with second check-valve 7, cold
Magnetic valve 9, second throttle 10 are provided between condenser 8 and heat exchanger 11；One outlet side of the three-way diverter valve 5 and the
One check-valves 6 is connected, and another outlet side is connected with the air entry and heat exchanger 11 of the 3rd compressor 4 respectively；3rd pressure
Contracting machine 4 is high pressure stage compressor.
The present invention can show and be used with general parallel machine when for freezing and refrigeration；Such as to be used for low temperature or it is quick-frozen when, beat
Switch, two-stage compression refrigeration can be achieved by the control of three-way diverter valve 5 and circulate.Two-stage refrigeration circulation is followed in single-stage refrigeration
Grow up on ring, its compression process is carried out in two stages, and the low-pressure refrigerant vapor for carrying out flash-pot 1 is introduced into first
Compressor 2, the second compressor 3 are compressed, and are compressed to intermediate pressure, and the 3rd compressor 4 is entered back into after cooling during rolling and is carried out
Recompression, enters finally into and is condensed in condenser 8, because the present invention also opens while opening and switching control three-way diverter valve 5
Magnetic valve 9 and second throttle 10, cooling during rolling are that heat absorption is vaporized under intermediate pressure using a small amount of liquid refrigerant, are made
The superheated steam of low-pressure stage discharge is cooled down, and reduces the suction temperature of hiigh pressure stage, while filled high pressure liquid refrigerant
Divide supercooling.General evaporating temperature should be freezed when being spent below -25 using Two-stage Compression.
