Description
Technical field
This utility model relates to a kind of multipurpose Condensing units, belongs to refrigeration plant technology
Field.
Background technology
Condensing units is by condenser, choke valve, vaporizer and multiple compressors etc.
Parts composition cooling cycle system.Present Condensing units manufacturing cost is high, utilization rate
Low, can only freezing and refrigeration or low-temperature quick-freezing, function singleness.
Utility model content
The purpose of this utility model there are provided a kind of multipurpose Condensing units, its energy
Realize single stage compress in parallel and Two-stage Compression, can freezing and refrigeration again can low-temperature quick-freezing, can enter
Row multiplexing can multi-state multipurpose work, thus has saved manufacturing cost, improves utilization rate.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of multipurpose compression
Condensation unit, including a vaporizer, described vaporizer be connected to the first compressor, the
Two compressors, the 3rd compressor, this first compressor, the second compressor, the 3rd compressor
Be arranged in parallel, this first compressor, the second compressor, the 3rd compressor the most all with condenser
Connecting, condenser is also connected with heat exchanger, first throttle valve in turn, first throttle valve with
Vaporizer connects, and arranges three-way diverter valve and the between the second compressor and the 3rd compressor
One check-valves, the inlet end at the 3rd compressor is provided with the second check-valves, condenser with
Electromagnetic valve, second throttle it is provided with between heat exchanger；The one of described three-way diverter valve goes out
Gas end and the first check-valves connect, another outlet side respectively with the air entry of the 3rd compressor and
Heat exchanger 11 connects；Described 3rd compressor is high pressure stage compressor.
The beneficial effects of the utility model are: this utility model can realize single stage compress in parallel and
Series connection Two-stage Compression, makes this utility model can be used for freezing and refrigeration and can be used for again low-temperature quick-freezing,
Improve the utilization rate of equipment, thus reduce cost.Described two-stage compression refrigeration circulation,
Refer to the cold-producing medium of flash-pot, be through low-pressure stage compressor and high pressure stage compressor two
After second compression, just enter condenser, its height arbitrarily downgrade compressor cylinder quantity or volumetric ratio general
Being about 1/3, employing three compressor as identical in compressor air-discharging amount is arranged in parallel, it is possible to
Use two compressors or multiple compressors combination setting, low pressure that compressor air-discharging amount is different
Level compressor air-discharging amount is slightly larger, and high pressure stage compressor capacity is slightly smaller, its high-low pressure pressure
Contracting machine number of cylinders or volumetric ratio are generally 1: 3 capacity.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of multipurpose Condensing units, including a vaporizer 1,
Described vaporizer 1 is connected to first compressor the 2, second compressor the 3, the 3rd compressor
4, this first compressor the 2, second compressor the 3, the 3rd compressor 4 is arranged in parallel, and this is years old
One compressor the 2, second compressor the 3, the 3rd compressor 4 is the most all connected with condenser 8, cold
Condenser 8 is also connected with heat exchanger 11, first throttle valve 12, first throttle valve 12 in turn
It is connected with vaporizer 1, threeway is set between the second compressor 3 and the 3rd compressor 4 and changes
To valve 5 and the first check-valves 6, the inlet end at the 3rd compressor 4 is provided with the second check-valves
7, between condenser 8 and heat exchanger 11, it is provided with electromagnetic valve 9, second throttle 10；
One outlet side of described three-way diverter valve 5 is connected with the first check-valves 6, and another outlet side is divided
It is not connected with air entry and the heat exchanger 11 of the 3rd compressor 4；Described 3rd compressor 4
For high pressure stage compressor.
This utility model, when for freezing and refrigeration, can show and use with general parallel machine；As
When low temperature to be used for or quick-freezing, open switch, can realize double by three-way diverter valve 5 control
Level compression kind of refrigeration cycle.Two-stage refrigeration circulation grows up on single-stage refrigeration cycle,
Its compression process is carried out in two stages, and the low-pressure refrigerant vapor carrying out flash-pot 1 is advanced
Enter first compressor the 2, second compressor 3 to be compressed, be compressed to intermediate pressure, through centre
Enter back into the 3rd compressor 4 after cooling to recompress, enter finally in condenser 8 cold
Solidifying, because this utility model also opens electricity while opening on-off control three-way diverter valve 5
Magnet valve 9 and second throttle 10, intercooling is to utilize a small amount of liquid refrigerant in centre
Vaporization heat absorption under pressure, the superheated steam making low-pressure stage discharge is cooled down, and reduces hiigh pressure stage
Suction temperature, make high pressure liquid refrigerant obtain the most supercool simultaneously.General evaporating temperature
Two-stage Compression should be used to freeze when spending below-25.
