Description
Technical field
The present invention relates to refrigerating plant, particularly relate to a kind of fountain refrigeration plant and control method.
Background technology
The cold transmittance process (heat transfer process in contrast) of current refrigeration plant: the cold-producing medium evaporation endothermic in evaporimeter, produce cold by the mode of " heat conduction " make to be close to evaporimeter liner of refrigeration equipment temperature reduce, 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 enclose inside gas lower the temperature, 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 also taken away by the mode of radiation heat transfer by refrigeration plant inwall and storing.
There are two subject matters in above-mentioned cold transmittance process: one is refrigeration plant inside is be main heat transferring medium with air, due to the density (1.164kg/m3 of air, 20 DEG C) and thermal conductivity factor (2.524 × 10-2W/ (m DEG C)) lower, cause heat transfer coefficient low; Two is that free convection and radiation heat transfer (refrigeration plant internal face and storing temperature range in) two kinds of coefficients of heat transfer of heat exchange mode own are lower, in 10 ~ 100W/ (m2 DEG C) scope.On the one hand, according to the thermal conduction study fundamental formular of 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 generally realizes by reducing evaporating temperature (namely increasing heat transfer temperature difference), and according to thermodynamics Carnot's theorem, refrigeration plant evaporating temperature is lower, coefficient of performance of refrigerating (COP) is lower, and 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 and (is generally positioned over evaporator pipeline exit); judge whether refrigeration indoor air temperature is reduced to setting value by the temperature at evaporator outlet place; under the air themperature of refrigeration plant inside is reduced to design temperature, namely compressor shuts down in limited time, until compressor is just started shooting work again when the air themperature of refrigeration plant inside rises to the temperature upper limit of temperature controller setting.Because air themperature and storing temperature exist the larger temperature difference; so when the compressor is shut down, storing temperature is not reduced to design temperature, and therefore storing heat heats refrigeration plant inner air very soon; temperature is elevated to compressor and again starts shooting work, directly causes 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 greatly shortens the service life of compressor.
At present, water is utilized to replace air as the water refrigeration plant of heat exchange refrigerant, by the forced-convection heat transfer of 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 have large water gaging to exist, the liquid level of water determines the producing level of refrigeration plant volume, and the existence of large water gaging simultaneously too increases the requirement of refrigeration plant intensity.In addition the evaporimeter of refrigeration system is positioned over refrigeration plant inside, occupies the dischargeable capacity of refrigeration plant.

Below in conjunction with accompanying drawing, the course of work of the present embodiment fountain refrigeration plant and control method are described, for the storing of refrigeration in casing 15 for beverage.
The duty of the present embodiment fountain refrigeration plant is mainly divided into startup, operation, shutdown and door body to open four kinds of operating modes; beverage is deposited in the inner chamber of casing 15 in the mode of vertical angles as far as possible; the spray droplet size of setting nozzle 7 is 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 refrigeration plant 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 refrigeration to be ejected on storing by nozzle 7 and to carry out heat exchange by fluid circulation system; Control system controls cooling cycle system and fluid circulation system simultaneously; Fluid circulation system controls cooling cycle system simultaneously, and the step of cooling cycle system is specially:
First judge whether door body is opened (now closing) according to the position switch 14 of unexpected winner body; Then temperature sensor 12 passes to the temperature signal of temperature controller 11 is normal temperature (because beverage is just put into), deviation is had with set temperature value, temperature controller 11 controls liquor pump 6 power supply immediately and connects, and fluid circulation system is started working, and connects compressor 1 power supply simultaneously;
After but compressor 1 power supply is connected, whether compressor 1 starts the control of also pressure difference sensor 13, judge whether the import and export of liquor pump 6 successfully set up pressure reduction by differential pressure pickup 13, if successfully set up pressure reduction, then fluid circulation system normally works, compressor 1 starts, and cooling cycle system is started working.
The 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 (for 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 (as sodium chloride, calcium chloride) the aqueous solution, according to the refrigeration of storing, cryogenic temperature selects the ejecting liquid be suitable for) water be pumped to evaporimeter 5 by liquor pump 6 and freeze, the cold of absorption refrigeration agent becomes cold water, cold water is atomized as high speed droplet by nozzle 7, droplet is directly injected to beverage packaging surface, with beverage heat exchange, simultaneously because droplet has very high flow velocity, getting on beverage to make beverage shake, cold is made to be delivered to beverage inside from beverage packaging fast, reduce the peripheral and inner temperature difference of beverage simultaneously, beverage is fully cooled, 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 pumped into evaporimeter 5 place through control valve 9, filter 10 by liquor pump 6 successively, enter 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 reduces gradually, and the temperature of backwater also reduces gradually.When temperature reaches 10 DEG C of setting, temperature controller 11 disconnects the power supply of liquor pump 6 and compressor 1 simultaneously, and fluid circulation system and cooling cycle system quit work simultaneously, enter shutdown operating mode.Due to constantly importing into of external heat, make internal beverage temperature increase gradually, when reaching the higher limit of temperature controller 11 startup, fountain refrigeration plant restarts.
Fountain refrigeration plant is when normally running, if opening door body is beaten in midway, for the liquid preventing nozzle 7 from spraying flies out casing 15, the power-off while that position switch 14 controlling liquor pump 6 and compressor 1, fluid circulation system and cooling cycle system are cut off simultaneously, and fountain refrigeration plant quits work.After a body closes, restart liquor pump 6 and compressor 1.
Analyze and find, cold and storing heat exchange just inner at fountain refrigeration plant at weakest link, thus the spray heat transfer technology that the coefficient of heat transfer can be reached 100000W/ (m2 DEG C) by the present invention is incorporated into fountain refrigerating device refrigeration field, simultaneously, propose the adjustable and spray droplet size of spray mode according to the philosophy of hydrodynamics, thermal conduction study to be determined by casing 15 interior reservoir species, with regard to refrigerating function, fountain refrigeration plant of the present invention, except selling the soft bottle beverage of refrigeration, can also realize the quick-frozen to fruit or packaged food.
Such as:
For bottled drink, select, close to the spray droplet size of column, liquid is sprayed storing surface, secondly less spray droplet size (scope of the median diameter value of drop is 0.5-2mm) then selected by (scope of the median diameter value of drop is 1-3mm), fruit to select larger spray droplet size (the median particle diameter of drop is 2-5.5mm), plastic bottle liquid beverage for glass, metal bottle dixie cup.This is because larger size droplet diameter has relatively high kinetic energy, beverage bottle and internal liquid vibrations can be made, also internal heat be strengthened while strengthening storing external heat-exchanging, realize cold/fast hot merit energy of speed of refrigeration plant further.
And for the storing of such as fruits, because of its surperficial rapid wear and inner heat conduction is the bottleneck of whole heat transfer, undue strengthening external heat-exchanging is little to overall contribution, therefore only need provide uniform low temperature environment, so select the spray droplet size close to 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 transmitted required for identical heat will reduce, technical scheme of the present invention is adopted to freeze, the temperature difference≤5 DEG C between the evaporating temperature of cooling cycle system and the temperature-sensitive bag temperature of temperature controller 11, and the temperature difference≤10 DEG C between the target temperature of storing, optimize the performance of cooling cycle system greatly.
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 have the larger temperature difference between evaporating temperature and storing.Wherein, as front, the introducing of spraying technique decreases the temperature difference between evaporating temperature and storing, and on the other hand, temperature sensor 12 is installed between liquid collection opening bottom refrigeration plant casing 15 and fluid reservoir 8 by the present invention.Under 128L refrigeration plant inside loads the prerequisite of 80 bottles of 500ml bottled waters, contrast by experiment, in 24h, conventional refrigeration equipment start-stop 100 times, and the only start and stop 2 times of the cold energy-saving cabinet of speed of the present invention.
As shown in Figure 2, except realizing the cold function of above-mentioned speed, the present embodiment fountain refrigeration plant is based on technique scheme, and difference is the storing in all right heating compartment 15, concrete, kind of refrigeration cycle circulation also comprises four-way change-over valve 2 and change-over switch (not shown); The structure of cooling cycle system is specially: the public entrance of four-way change-over valve 2 and public outlet are connected with the blast pipe of compressor 1 and air intake duct respectively, other two reduction of fractions to a common denominators of four-way change-over valve 2 are not connected with evaporimeter 5 with condenser 3, and capillary 4 is located between condenser 3 and evaporimeter 5; Change-over switch is connected with four-way change-over valve 2 by controlling power supply.
Specifically, need by refrigerating state switch to heat state time, pull change-over switch, control power supply to four-way change-over valve 2 one high level pulses, the four-way change-over valve 2 realized commutates, the flow direction of cold-producing medium changes, the exchange function of evaporimeter 5 and condenser 3, then realize fast hot merit energy, can make the present embodiment fountain refrigeration plant in the winter time or other desired occasion as " hot drink " heater, improve energy utilization efficiency, reduce vacancy rate, give full play to the frequency of utilization of the present embodiment fountain refrigeration plant, become the multifunctional electric appliance in full season.
