Description
Technical field
This utility model is related to a kind of refrigeration unit, specifically a kind of refrigeration unit of employing cross valve control.
Background technology
The composition of refrigeration unit：Compressor (class compressor subsystem), condenser, expansion valve, vaporizer and control system
Deng, becoming increasingly popular as improvement of people's living standards clothes is dry-cleaned, dry cleaner becomes the key equipment of industrial washing.Freeze back
The cooling circulation for receiving unit is used primarily on dry-cleaning equipment, makes the heated quickly residual solvent on medicated clothing, vaporization, condensation, liquid
Change and reclaim.Due to freezing, chilling temperature is lower than water-cooled temperature, and the cycle for drying recovery can shorten, and solvent recovering rate is high, molten
The consumption of agent is 1% or so, therefore at the end of drying, in washing drum, residual tetrachloroethylene steam seldom, reduces nuisance
The discharge of matter, reaches the purpose of energy saving.
Utility model content
For achieving the above object, this utility model provides following technical scheme：
A kind of refrigeration unit of employing cross valve control, including compressor, water condenser, cross valve, check valve A, unidirectional
Valve B, recuperation of heat heater, vaporizer, heating power expansion valve, liquid-sighting glass and filter, the outfan connection four-way of the compressor
One end of valve, and other three end of cross valve connects the input of recuperation of heat heater, one end of check valve A and compressor respectively
Input, wherein the outfan of recuperation of heat heater by check valve B connect water condenser input, check valve A's is another
One end also connects the input of water condenser, and the outfan of water condenser is sequentially connected filter, liquid-sighting glass, heating power by pipeline
Expansion valve and the input of vaporizer, the outfan of vaporizer connect the input of compressor.
As further program of the utility model：The inside of the water condenser arranges cooling water system.
Compared with prior art, the beneficial effects of the utility model are：
1st, unique four-way change-over valve structure, structure simpler, cost are lower；
2nd, recuperation of heat structure Energy Efficiency Ratio is higher.
3rd, this goes to heat to dry cleaner air channel using the heat produced when reclaiming using refrigeration, so greatly reduces drying
The energy more than 40% of Shi Jiare.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Embodiment in based on this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1 is referred to, in this utility model embodiment, a kind of refrigeration unit of employing cross valve control, including compressor
1st, water condenser 2, cooling water system 3, cross valve 4, check valve A5, check valve B6, recuperation of heat heater 7, vaporizer 8, heating power
Expansion valve 9, liquid-sighting glass 10 and filter 11, the outfan of the compressor 1 connect one end of cross valve 4, and cross valve 4 is another
Outer three end connects the input of the input of recuperation of heat heater 7, one end of check valve A5 and compressor 1 respectively, wherein hot time
The outfan for receiving heater 7 connects the input of water condenser 2 by check valve B6, and the other end of check valve A5 also connects water-cooled
The input of condenser 2, the outfan of water condenser 2 are sequentially connected filter 11, liquid-sighting glass 10, heating power expansion valve 9 by pipeline
And the input of vaporizer 8, the input of the outfan connection compressor 1 of vaporizer 8.
The inside of the water condenser 2 arranges cooling water system 3.
Operation principle of the present utility model is：
When machine is dried, compressor 1 is powered, and check valve B6 is powered, and the low-pressure low-temperature gas produced in vaporizer 8 is inhaled
Entering, high temperature and high pressure gas being compressed into through compressor 1 and recuperation of heat heater 7 is discharged to by cross valve 4, gas goes out recuperation of heat and adds
Hot device 7 carries out heat exchange with the relatively low water of temperature through check valve B6 in water condenser 2, and refrigerant gas are condensed into liquid,
Liquid passes through filter 11, liquid-sighting glass 10, heating power expansion valve 9 so that pressure and temperature enters vaporizer 8 after reducing simultaneously,
The heat of cooled medium constantly being absorbed in vaporizer 8 and being vaporized into steam, the refrigerant vapour of generation is again by compressor 1
Siphon away.
When deodorization lowered the temperature by machine, cross valve 4 is powered, and check valve A5 is powered and connects so that it is high that compressor 1 is compressed into high temperature
Body of calming the anger is discharged to check valve A5 through cross valve 4, and in water condenser, the water relatively low with temperature carries out heat exchange, and other principles are same
On.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type is by claims rather than described above is limited, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as restriction
Involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
Contain an independent technical scheme, this narrating mode of description is only that those skilled in the art should for clarity
Using description as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined
Understandable other embodiment.
