Description
Technical field
The present invention relates to refrigerating plant, particularly relate to a kind of fountain storing equipment and control method.
Background technology
The cold transmittance process (heat transfer process is in contrast) of current refrigeration plant: the cold-producing medium evaporation endothermic in evaporimeter, produced cold makes the liner of refrigeration equipment temperature being close to evaporimeter reduce by way of " heat conduction ", the liner of refrigeration equipment of low temperature passes through free convection, radiation (if it is forced convertion that there is the heat exchange mode of forced convection device inside) makes refrigeration plant internal confining gas cooling, cryogenic gas carries out heat exchange by free convection (if it is forced convertion that there is the heat exchange mode of forced convection device inside) 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 thermal conductivity factor (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 reducing evaporating temperature (i.e. increasing heat transfer temperature difference), and according to thermodynamics Carnot's theorem, refrigeration plant evaporating temperature is lower, coefficient of performance of refrigerating (COP)
Lower, cooling rate is slower；On the other hand; the temperature-sensitive bag of current refrigeration plant temperature controller is placed on the pipeline of refrigeration system (being typically placed at evaporator pipeline exit); judge whether refrigeration 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 is quickly the heating of 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 start and stop of compressor frequently make the functional reliability of refrigerator-freezer decline, and is greatly shortened the service life of compressor.
At present, utilize water instead of air as the water refrigeration plant of heat exchange refrigerant, forced-convection heat transfer by water and 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 simultaneously a large amount of water too increases the requirement of refrigeration plant intensity.In addition the evaporimeter of refrigeration system is positioned over inside refrigeration plant, occupies the dischargeable capacity of refrigeration plant.

As shown in Figure 1, the present embodiment fountain storing equipment, mainly includes that the 8th, compressor the 1st, condenser the 3rd, capillary the 4th, evaporimeter the 5th, liquid pump the 6th, nozzle the 7th, fluid reservoir regulates valve the 9th, filter the 10th, temperature controller the 11st, temperature sensor the 12nd, differential pressure pickup the 13rd, position switch 14 and casing 15.Wherein, compressor the 1st, condenser the 3rd, capillary 4 and evaporimeter 5 form cooling cycle system；Liquid pump the 6th, filter the 10th, nozzle the 7th, fluid reservoir 8 and regulation valve 9 form fluid circulation system；Temperature controller the 11st, temperature sensor the 12nd, differential pressure pickup 13 and position switch 14 forming control system.
The structure of cooling cycle system is particularly as follows: compressor the 1st, condenser the 3rd, capillary 4 and evaporimeter 5 circulate the refrigerating circuit being joined together to form for refrigerant flowing successively.
The structure of fluid circulation system is particularly as follows: the ejecting liquid of liquid pump 6 output is transported to nozzle 7 after freezing through evaporimeter 5, nozzle 7 stretches into the inner chamber of casing 15, liquid pump 6 sequentially passes through filter and the 10th, regulates valve 9 and be connected with fluid reservoir 8, and fluid reservoir 8 is connected to the inner chamber of casing 15.Wherein, the intracavity bottom of casing 15 could be formed with liquid collection opening (not shown), the ejecting liquid that fluid reservoir 8 is connected in collection tank 15 with this osculum；Additionally, evaporimeter 15 can use the structure such as plate type heat exchanger or double pipe heat exchanger, evaporimeter 15 has two streams, wherein a stream flows for refrigerant, another stream flows for spray liquid, and liquid pump 6 is connected with nozzle 7 by evaporimeter 5, or, directly being connected by pipeline between liquid pump 6 with nozzle 7, this pipeline is attached to the spray liquid on evaporimeter 5 to flow through in this pipeline by evaporimeter 5 refrigeration.
The structure of control system is particularly as follows: temperature sensor 12 is located between the liquid collection opening bottom fluid reservoir 8 and casing 15, temperature controller 11 is connected respectively with temperature sensor the 12nd, liquid pump the 6th, compressor 1, differential pressure pickup 13 is located between the import and export of liquid pump 6, differential pressure pickup 13 is additionally coupled to compressor 1, position switch 14 is located at the door body of casing 15, for judging whether the door body (not shown) on casing 15 is opened.
Below in conjunction with the accompanying drawings the course of work and control method of the present embodiment fountain storing equipment is illustrated, as a example by casing 15, the storing of refrigeration is as beverage.
The duty of the present embodiment fountain storing equipment is broadly divided into startup, operation, shutdown and door body and 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 fountain storing equipment enters the start operating performance stage.
Cooling cycle system is by evaporimeter 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 the position switch 14 according to unexpected winner body judges whether door body opens (being now turned off)；Then the temperature signal that temperature sensor 12 passes to temperature controller 11 is normal 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 evaporimeter 5 of cooling cycle system produces cold，Fluid circulation system is (as a example by water，Ejecting liquid is pure water、Ethylene glycol、One or more or the ethanol water of phenol in glycerine or the soluble-salt of alkali and alkaline earth metal ions are (such as sodium chloride、Calcium chloride) the aqueous solution，Refrigeration according to storing、Cryogenic temperature selects the ejecting liquid being suitable for) water liquid pump 6 be pumped to evaporimeter 5 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 very high 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 beverage periphery and the internal temperature difference 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 then adjusted valve the 9th, filter 10 successively and be pumped at evaporimeter 5 by liquid pump 6, enter next round circulation.
Water can flow through temperature sensor 12 when entering fluid reservoir 8 from the liquid collection opening of casing 15, 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, and fluid circulation system and cooling cycle system quit work simultaneously, enters and shuts down operating mode.Constantly incoming due to external heat, makes internal beverage temperature be gradually increasing, and when reaching the higher limit that temperature controller 11 starts, fountain storing equipment restarts.
Fountain storing equipment is when properly functioning, if door body is opened in midway, fly out casing 15 for the liquid that prevents nozzle 7 from spray, power-off while position switch 14 controls liquid pump 6 and compressor 1, fluid circulation system and cooling cycle system are cut off simultaneously, and fountain storing equipment quits work.After door body is closed, restart liquid pump 6 and compressor 1.
Analyze discovery, cold and storing heat exchange at weakest link just at fountain storing device interior, 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 fountain storing equipment refrigerating field, simultaneously, propose according to the philosophy of hydrodynamics, thermal conduction study that spray mode is adjustable and spray droplet size is determined by the internal storing species of casing 15, for refrigerating function, fountain storing equipment of the present invention, except selling the soft bottle beverage of refrigeration, can also realize the quick-frozen to fruit or packaged food.
For example:
For bottled drink, select, close to the spray droplet size of column, liquid sprayed 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, beverage bottle 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, therefore 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, transmit the temperature difference required for identical heat will reduce, technical scheme is used to freeze, the temperature difference≤5 DEG C between the temperature-sensitive bag temperature of the evaporating temperature of cooling cycle system and temperature controller 11, 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 the position that two: is temperature controller temperature-sensitive bag；Two is to have the bigger temperature difference between evaporating temperature and storing.Wherein, as it was previously stated, 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.On the premise of loading 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.
Embodiment two
Additionally, as in figure 2 it is shown, in addition to realizing above-mentioned quickly cooling function, the present embodiment fountain storing equipment is based on above-described embodiment one, difference is can be concrete with the storing in heating compartment 15, and the circulation of described kind of refrigeration cycle also includes four-way change-over valve 2 and switching switch (not shown)；The structure of cooling cycle system is particularly as follows: common inlet and the public outlet of four-way change-over valve 2 are connected with blast pipe and the air intake duct 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 evaporimeter 5, and capillary 4 is located between condenser 3 and evaporimeter 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 is to 2 one high level pulses of four-way change-over valve, the four-way change-over valve 2 realizing commutates, the flow direction of cold-producing medium changes, evaporimeter 5 and the exchange function of condenser 3, then realize speed hot merit energy, can make the present embodiment fountain storing equipment in the winter time or other desired occasion is as " hot drink " heater, improve energy utilization efficiency, reduce vacancy rate, give full play to the use frequency of the present embodiment fountain storing equipment, become the multifunctional electric appliance in full season.
