Embodiment
The refrigeration host computer refrigerating circulatory system of the utility model suitable for supercooling ability of swimming characteristics of dynamic ice slurry preparation system.Reference
Accompanying drawing 1, the circulatory system includes the dynamic ice pulp grinder 1 of connection ice slurry water circulation, the refrigeration host computer 8 of connection cooling tower water circulation, system
Cold main frame 8 is provided with evaporator 8a and condenser 8b, and evaporator 8a refrigerating mediums outlet conduit is connected with the entrance of dynamic ice pulp grinder 1,
The outlet of dynamic ice pulp grinder 1 is connected through water pump 10 with evaporator 8a refrigerating medium inlet ducts.The utility model is dynamic including being arranged on
Temperature sensor 2 before the entrance of state ice slurry machine 1, be arranged on refrigeration host computer 8 evaporator 8a refrigerating medium Inlet and outlet pipe
Between by-pass line, and in by-pass line set a control valve for adjustable bypass flow 4 so that refrigeration master
The refrigerating agent flux of machine evaporator 8a can the stable operation under conditions of less than the refrigerating medium circular flow of dynamic ice pulp grinder 1, separately
The refrigerating agent flux that an outer part has more then by by-pass line bypass refrigeration host computer 8 and with refrigeration host computer evaporator 8a export
Low temperature refrigerating medium is recycled into dynamic ice pulp grinder 1 again after mixing.
Temperature sensor 2 is used to sense the refrigerant temperature in pipeline where it.The aperture of control valve can be adjusted freely
Section.The aperture of control valve is adjusted according to the refrigerant temperature that temperature sensor is sensed, when dynamic ice pulp grinder entrance refrigerating
When agent temperature exceedes design temperature (usually -3 DEG C), the aperture of control valve reduces, otherwise then increases.
In Fig. 1, by-pass line is divided into two parts, i.e. by-pass line 3 and by-pass line 5 by control valve 4, evaporator 8a's
Refrigerating medium outlet conduit includes the refrigerating medium first outlet pipeline 6, the refrigerating medium second outlet pipeline 7 that are connected；By-pass line 3 connects
It is connected between control valve 4 and the refrigerating medium inlet duct 9 of evaporator 8a, by-pass line 5 is connected to control valve 4 and refrigerating medium
Between the end of first outlet pipeline 6, refrigerating medium second outlet pipeline 7 be connected to the end of refrigerating medium first outlet pipeline 6 with
Between the entrance of dynamic ice pulp grinder 1.
Workflow of the present utility model is as follows：The condenser 8b of refrigeration host computer 8 is connected with cooling tower water circulation, by it
In the heat that produces when refrigeration host computer 8 is run of cooling water circulation continually take cooling tower to side by side in surrounding air.
The ice water circulation side of dynamic ice pulp grinder 1 then constantly absorb by the cold from refrigeration host computer 8 that the refrigerating circulatory system is transmitted and
Water is constantly changed into ice slurry.According to supercooling ability of swimming dynamic ice-making technological requirement, the refrigerating medium side entrance temperature of dynamic ice pulp grinder 1
- 3 DEG C are necessary for, outlet is necessary for -1 DEG C, and the temperature fluctuation range for being allowed is very narrow and small.- 1 DEG C of refrigerating medium is from characteristics of dynamic ice slurry
Machine 1 out after, the refrigerating medium side entrance of the evaporator 8a of refrigeration host computer 8 is sent to through water pump 10, before it enters evaporator 8a
It is divided into two fluids, flows to by-pass line 5 and the flow direction steaming of refrigerating medium inlet duct 9 through evaporator through by-pass line 3 respectively
Hair device 8a.It is the part by the refrigerating agent flux of dynamic ice pulp grinder 1, its temperature by the refrigerating agent flux of evaporator 8a
It is cool below -3 DEG C of lower temperature value (such as -4 DEG C are lower) by refrigeration host computer 8, and from the refrigerating medium first of evaporator
Outlet conduit 6 flows out.By the refrigerating medium of by-pass line 3 and by-pass line 5 then keep -1 DEG C it is temperature-resistant directly around evaporation
Lower temperature refrigerating medium in device 8a, with the refrigerating medium first outlet pipeline 6 of evaporator converges the load for flowing to evaporator after mixing
Cryogen second outlet pipeline 7, by after above-mentioned mixing, the refrigerant temperature quilt in the refrigerating medium second outlet pipeline 7 of evaporator
- 3 DEG C of target temperature is blent, the refrigerating medium wing passage of dynamic ice pulp grinder 1 is then fed to.
Under above-mentioned workflow, the refrigerating agent flux and the temperature difference (big flow and the small temperature difference) of dynamic ice pulp grinder 1 reach
The technical requirements of ability of swimming characteristics of dynamic ice slurry reparation technology are subcooled, meanwhile, the refrigerating agent flux in the evaporator 8a of refrigeration host computer 8 but shows
Writing reduces, and tends to refrigeration host computer and imports and exports the relatively small amount constant flow under the temperature difference (5 DEG C) in standard, thus its flow resistance is significantly
It is reduced to rational rank.Due under steady-state operation situation heat exchange amount of the refrigerating medium in evaporator 8a with its in characteristics of dynamic ice slurry
Heat exchange amount in machine 1 must be equal, thus evaporator 8a import and export refrigerating mediums the temperature difference be naturally larger than dynamic ice pulp grinder 1 into and out of
The temperature difference of mouthful refrigerating medium, so when evaporator refrigerating medium first outlet pipeline 6 in refrigerant temperature be inevitably less than it is above-mentioned dynamic
- 3 DEG C of the design object temperature of the entrance refrigerating medium of state ice slurry machine 1.But it is less than in the refrigerating medium first outlet pipeline 6 of forgoing evaporators
The refrigerating medium of -3 DEG C of design object temperature just further through with from the part with higher temperature (- 1 DEG C) in by-pass line 5
Refrigerating medium is mutually mixed and blent, and then reaches -3 DEG C required of design object temperature.Understand in sum, it is new by this practicality
Type device, both ensure that the big flow of the import and export refrigerating medium of dynamic ice pulp grinder 1, small temperature difference technical requirements, further through by-pass line
The part of refrigerating medium in evaporator 8a is shunted so that refrigeration host computer 8 is realized or tends to realizing the low discharge of its standard, the big temperature difference
Design operating conditions, and the flow resistance of refrigeration host computer side in the refrigerating medium circulatory system is finally greatly reduced so that water circulating pump
10 realize significantly energy-conservation.
The purpose that the utility model sets temperature sensor 2 is to more accurately judge the aperture size of control valve 4
Adjusted with direction.When the refrigerant temperature of the sensing of temperature sensor 2 is higher than design object value (- 3 DEG C), now needs to reduce and adjust
Save the aperture of valve 4.Because after reducing the aperture of control valve 4, bypass flow reduction, the refrigerating agent flux in evaporator 8a increases
Greatly, heat exchange is strengthened, the refrigerating capacity increase of refrigeration host computer 8, thus final mixed in the refrigerating medium second outlet pipeline 7 of evaporator
Refrigerant temperature with after can be reduced so that the entrance refrigerant temperature of dynamic ice pulp grinder 1 falls back to design object value (- 3 DEG C).
Conversely, when the refrigerant temperature of the sensing of temperature sensor 2 is less than design object value (- 3 DEG C), now needing to increase control valve
4 aperture.Because after increasing the aperture of control valve 4, bypass flow is raised, the refrigerating agent flux in evaporator 8a reduces, and changes
Heat weakens, the refrigerating capacity reduction of refrigeration host computer 8, thus finally after mixing in the refrigerating medium second outlet pipeline 7 of evaporator
Refrigerant temperature can raise so that the entrance refrigerant temperature of dynamic ice pulp grinder 1 goes back up to design object value (- 3 DEG C).
As described above, just can preferably realize the utility model.
