Description
Technical field
The present invention relates to refrigerating plant, particularly relate to a kind of spray refrigeration plant and control method.
Background technology
The cold transmittance process (heat transfer process is in contrast) of refrigeration plant at present: the cold-producing medium evaporation endothermic in vaporizer, produced cold makes the liner of refrigeration equipment temperature being close to vaporizer reduce by the way of " heat conduction ", the liner of refrigeration equipment of low temperature passes through free convection, radiation (if inside has the heat exchange mode of forced convection device to be forced convertion) makes refrigeration plant internal confining gas cooling, cryogenic gas carries out heat exchange by free convection (if inside has the heat exchange mode of forced convection device to be forced convertion) and storing, the heat of storing is taken away.The heat of storing is taken away also by the mode of radiation heat transfer by refrigeration plant inwall with storing.
There are two subject matters in above-mentioned cold transmittance process: one is to be to be main heat transferring medium with air inside refrigeration plant, density (1.164kg/m3 due to air, 20 DEG C) and heat conductivity (2.524 × 10-2W/ (m DEG C)) relatively low, cause heat transfer coefficient low；Two is that two kinds of own coefficients of heat transfer of heat exchange mode of free convection and radiation heat transfer (refrigeration plant internal face with in storing temperature range) are relatively low, in the range of 10～100W/ (m2 DEG C).On the one hand, thermal conduction study fundamental formular according to the heat exchange amount=coefficient of heat transfer × heat transfer temperature difference × heat exchange area, when refrigeration plant storing is more, need higher heat exchange heat, refrigeration plant is typically realized by reduction evaporating temperature (i.e. increasing heat transfer temperature difference), and according to thermodynamics Carnot's theorem, refrigeration plant evaporating temperature is the lowest, coefficient of performance of refrigerating (COP)
The lowest, cooling rate is the slowest；On the other hand; the temperature-sensitive bag of refrigeration plant temperature controller is placed on the pipeline of refrigeration system (being typically placed at evaporator pipeline exit) at present; judge whether cold preservation indoor air temperature is reduced to setting value by the temperature at evaporator outlet; when the air themperature within refrigeration plant is reduced to design temperature lower limit, compressor is shut down, until compressor just turns back on work when the air themperature within refrigeration plant rises to the temperature upper limit of temperature controller setting.Owing to air themperature exists the bigger temperature difference with storing temperature; so when the compressor is shut down, storing temperature is not reduced to design temperature, and therefore storing heat quickly heats refrigeration plant inner air; temperature is increased to compressor and turns back on work, directly results in the frequent start-stop of compressor.Cooling rate makes the energy saving of refrigerator-freezer in urgent need to be improved slowly, and the functional reliability that the start and stop of compressor frequently make refrigerator-freezer declines, and is greatly shortened the service life of compressor.
At present, utilize water instead of air as the water refrigeration plant of heat exchange coolant, forced-convection heat transfer by water Yu storing, heat transfer coefficient scope is at 1000～10000W/ (m2 DEG C), this adds the heat transfer coefficient of refrigeration plant to a certain extent, but the inside of water refrigeration plant must be with the presence of a large amount of water, and the liquid level of water determines the producing level of refrigeration plant volume, the existence of the most a large amount of water too increases the requirement of refrigeration plant intensity.In addition the vaporizer of refrigeration system is positioned over inside refrigeration plant, occupies the dischargeable capacity of refrigeration plant.

Wherein, casing 15 in the present embodiment is configured with hairbrush water removal body, utilize hairbrush water removal body that the ejecting liquid on storing surface is carried out spin-drying, wherein, the version of hairbrush water removal body has multiple, such as: as it is shown on figure 3, hairbrush water removal body includes brush roll 151 and for the motor 152 driving described brush roll 151 to rotate.Concrete, brush roll 151 can rotate in casing 15, and provide power by motor 152 for brush roll 151, and in brush roll 151 rotation process, elastomeric bristles in brush roll 151 will be resisted against stress bending on storing surface, and when being separated from storing, the water on storing surface is ejected by elastomeric bristles, such that it is able to be purged the ejecting liquid on storing surface.Wherein, hairbrush water removal body can drive it to move up and down by elevating mechanism 154, when needing the ejecting liquid removing storing surface, hairbrush water removal body moves close to storing, and elevating mechanism can be linear electric motors or cylinder or other there is the mechanism of elevating function.Preferably, in order to collect the ejecting liquid on storing surface, the back of the inner chamber of casing 15 be provided with described brush roll 151 with the use of a plurality of water leg 153, by controlling the direction of rotation of motor 152, the ejecting liquid on storing surface is launched by brush roll 151, and the back of the inner chamber of casing 15 is also back to the bottom of casing 15 by water leg 153 collection and is recycled.
Work process and control method to the present embodiment spray refrigeration plant illustrate, as a example by casing 15, the storing of cold preservation is as beverage below in conjunction with the accompanying drawings.
The duty of the present embodiment spray refrigeration plant is broadly divided into startup, runs, shuts down and door body opens four kinds of operating modes; beverage is deposited in the inner chamber of casing 15 in the way of vertical angles as far as possible; set the spray droplet size of nozzle 7 to median size; the particle size values of the spray droplet of median is 1-3mm; close door body; temperature controller 11 set temperature value is 10 DEG C, switches on power, and the present embodiment spray refrigeration plant enters the start operating performance stage.
Cooling cycle system is by vaporizer 5 and the ejecting liquid heat exchange in fluid circulation system, and the ejecting liquid after fluid circulation system will be freezed by nozzle 7 is ejected on storing and carries out heat exchange；Control system controls cooling cycle system and fluid circulation system simultaneously；Fluid circulation system controls cooling cycle system simultaneously, the step of cooling cycle system particularly as follows:
First judge whether door body opens (being now turned off) according to the position switch 14 of unexpected winner body；Then temperature sensor 12 passes to the temperature signal of temperature controller 11 is room temperature (because beverage is just put into), has deviation with set temperature value, and temperature controller 11 controls liquid pump 6 power on immediately, and fluid circulation system is started working, and is also turned on compressor 1 power supply；
But after compressor 1 power on, whether compressor 1 starts the control of also pressure difference sensor 13, judged by differential pressure pickup 13 whether the import and export of liquid pump 6 are successfully established pressure reduction, if being successfully established pressure reduction, then fluid circulation system normally works, compressor 1 starts, and cooling cycle system is started working.
nullThe transmittance process of cold is: the cold-producing medium evaporation endothermic in the vaporizer 5 of cooling cycle system produces cold，Fluid circulation system is (as a example by water，Ejecting liquid is pure water、Ethylene glycol、The soluble-salt of one or more or the ethanol water of phenol or alkali and alkaline earth metal ions in glycerol is (such as sodium chloride、Calcium chloride) aqueous solution，Cold preservation according to storing、Cryogenic temperature selects the ejecting liquid being suitable for) water be pumped to vaporizer 5 by liquid pump 6 and freeze，The cold of absorption refrigeration agent becomes cold water，Cold water is high speed droplet by nozzle 7 atomization，Droplet is directly injected to beverage packaging surface，With beverage heat exchange，Simultaneously because droplet has the highest flow velocity，Get to and beverage on beverage, can be made to shake，Cold is made quickly to be delivered to beverage inside from beverage packaging，Reduce the temperature difference that beverage is peripheral with internal simultaneously，Make beverage sufficiently cool；Through with beverage heat exchange after drop temperature raise, and come together in bottom casing 15, enter the fluid reservoir 8 of fluid circulation system by gravity from liquid collection opening, be adjusted valve 9 the most successively, filter 10 is pumped at vaporizer 5 by liquid pump 6, enters next round circulation.
Water can flow through temperature sensor 12 when the liquid collection opening of casing 15 enters fluid reservoir 8, and the temperature signal of water is passed to temperature controller 11.Due to the continuous transmission of cold, the temperature of beverage is gradually lowered, and the temperature of backwater is gradually lowered.When temperature reaches 10 DEG C set, temperature controller 11 simultaneously switches off liquid pump 6 and the power supply of compressor 1, fluid circulation system and cooling cycle system quit work simultaneously, enters and shuts down operating mode.The most incoming due to external heat, makes internal beverage temperature be gradually increasing, and when reaching the higher limit that temperature controller 11 starts, spray refrigeration plant restarts.
Spray refrigeration plant is when properly functioning, if door body is opened in midway, the liquid for preventing nozzle 7 from spray flies out casing 15, and position switch 14 controls power-off while of liquid pump 6 and compressor 1, fluid circulation system and cooling cycle system are cut off simultaneously, and spray refrigeration plant quits work.After door body is closed, restart liquid pump 6 and compressor 1.
Analyze and find, cold is just spraying inside refrigeration plant with storing heat exchange at weakest link, thus the spray heat transfer technology that the coefficient of heat transfer be can reach 100000W/ (m2 DEG C) by the present invention is incorporated into spray refrigerating device refrigeration field, simultaneously, philosophy according to hydrodynamics, thermal conduction study proposes that spray mode is adjustable and spray droplet size is determined by the internal storing kind of casing 15, for refrigerating function, the present invention sprays refrigeration plant except selling cold preservation soft bottle beverage, it is also possible to realize fruit or the quick-freezing of packaged food.
Such as:
For bottled drink, select, close to the spray droplet size of column, liquid sprays storing surface, select bigger spray droplet size (the median particle diameter of drop is 2-5.5mm), plastic bottle liquid beverage secondly (the median diameter value of drop is in the range of 1-3mm), fruit then to select less spray droplet size (the median diameter value of drop is in the range of 0.5-2mm) for glass, metal bottle dixie cup.This is because bigger size droplet diameter has of a relatively high kinetic energy, carafe and internal liquid vibrations can be made, also internal heat is strengthened while strengthening storing external heat-exchanging, realize the quickly cooling/speed hot merit energy of refrigeration plant further.
And for such as the storing of fruits, because its surface rapid wear and internal heat conduction are the bottlenecks of whole heat transfer, undue strengthening external heat-exchanging is little to overall contribution, the most only need to provide uniform low temperature environment, so selecting close to the spray droplet size being atomized.
The raising of casing 15 internal heat coefficient makes the coefficient of heat transfer from cold-producing medium to storing improve, the temperature difference required for transmitting identical heat will reduce, technical scheme is used to freeze, the temperature difference≤5 DEG C between evaporating temperature and the temperature-sensitive bag temperature of temperature controller 11 of cooling cycle system, and the temperature difference≤10 DEG C between the target temperature of storing, are greatly optimized the performance of cooling cycle system.
The basic reason of conventional refrigeration equipment high frequent start and stop under heavy load has two: one to be the position of temperature controller temperature-sensitive bag；Two is to have the bigger temperature difference between evaporating temperature and storing.Wherein, as before, the introducing of spraying technique decreases the temperature difference between evaporating temperature and storing, on the other hand, temperature sensor 12 is installed on the liquid collection opening bottom refrigeration plant casing 15 and between fluid reservoir 8 by the present invention.Load on the premise of 80 bottles of 500ml bottled waters inside 128L refrigeration plant, by Experimental comparison, in 24h, conventional refrigeration equipment start-stop 100 times, and the quickly cooling energy-saving cabinet only start and stop of the present invention 2 times.
As in figure 2 it is shown, in addition to realizing above-mentioned quickly cooling function, the present embodiment spray refrigeration plant is based on technique scheme, and difference is can be concrete with the storing in heating compartment 15, and kind of refrigeration cycle circulation also includes four-way change-over valve 2 and switching switch (not shown)；The structure of cooling cycle system is particularly as follows: the common inlet of four-way change-over valve 2 and public outlet are connected with exhaustor and the suction nozzle of compressor 1 respectively, other two reduction of fractions to a common denominators of four-way change-over valve 2 are not connected with condenser 3 and vaporizer 5, and capillary tube 4 is located between condenser 3 and vaporizer 5；Switching switch is connected with four-way change-over valve 2 by controlling power supply.
Specifically, needs are switched to by refrigerating state when heating state, pull switching switch, control power supply to 2 one high level pulses of four-way change-over valve, the four-way change-over valve 2 realized commutates, the flow direction of cold-producing medium changes, vaporizer 5 and the exchange function of condenser 3, then realize speed hot merit energy, in the winter time or other desired occasion is as " hot drink " heater can to make the present embodiment spray refrigeration plant, improve energy utilization efficiency, reduce vacancy rate, give full play to the use frequency of the present embodiment spray refrigeration plant, become the multifunctional electric appliance in full season.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
