Description
Technical field
The present invention relates to refrigeration plant, more particularly relate to a kind of cold-storage material that utilizes and accumulate cold when freezer compressor moves, released cold quantity stops the refrigerator of temperature rise when compressor shutdown or outage.
Background technology
Electricity Demand increases very fastly since the reform and opening-up, and especially peak of power consumption and low ebb gap are constantly widening in one day, and the inhomogeneous situation of operation of power networks is on the rise.At this situation, country adopts a plurality of policies to encourage the exploitation energy-conserving products, and some areas are the compulsory implement policy of using electricity in off-peak hours also.The power consumption of household electrical appliance accounts for the very big proportion of total electricity consumption, and in the face of energy-intensive whole world situation, the exploitation energy-conserving product becomes the main flow of development.
At the beginning of the eighties in last century, from a kind of energy-efficient cold-storage technology that grows up such as the U.S., Japan, utilize the valley power refrigeration at night that cold is accumulated, by day with the cold refrigeration of accumulating, thereby avoid using the peak power on daytime.So far, comparatively popular cold-storage mode has three kinds, i.e. water cold-storage, ice cold-storage, excellent attitude salt cold-storage.The water cold-storage as cool storage medium, is one of cold-storage important way with water, but because there is not phase transformation in the water cold-storage, is sensible heat formula cold-storage, so the cold-storage ability is lower.And the ice cold-storage to be the phase transformation that utilizes water freeze to store after with water for cooling, when peak of power consumption, take out and use.Excellent attitude salt is the mixture that is formed by inorganic salts (hydrate of sodium sulphate is a Main Ingredients and Appearance) and water and additive allotment, and the similar ice cold-storage of its cold-storage principle mainly is to utilize material phase transformation to store cold, but generally all phase transformations at high temperature.
At present, above-mentioned three kinds of cold-storage modes are mainly used on the air-conditioning product, and the application in refrigerator is not extensive, and the cool storage function of current refrigerator is mainly realized at refrigerating chamber placement regenerator, the refrigerator product of refrigerating chamber band cool storage function seldom, and its transformation temperature is all subzero.A kind of implementation is only to be that refrigerating chamber has cool storage function, and after having a power failure or shutting down, regenerator is released cold, delays the temperature recovery of refrigerating chamber, and the user can have a power failure fresh-keeping by the regenerator immigration refrigerating chamber by artificial cold-storage after power failure; Another kind of implementation is that cold air duct is released in design between refrigerating chamber and refrigerating chamber, be equipped with fan, battery, having a power failure or releasing under the cold state, via the air channel cold is extracted into refrigerating chamber top from lower freezer compartment by fan, freezes and alleviate that refrigerator has a power failure or the temperature recovery of refrigerating chamber when releasing cold state.This mode need increase the fan energy consumption, there is the food air drying problem,, brings problems such as refrigerating taint of odour, the easy frosting of refrigerating chamber because refrigerating chamber is communicated with by the air channel with refrigerating chamber, for the fresh-keeping function of realizing having a power failure also needs to be equipped with battery, and fresh keeping time is subjected to the influence of accumulator electric-quantity.On June 6th, 2002 Chinese utility model patent disclosed, that notification number is CN2480786 disclose a kind of cold that can between refrigerating chamber and refrigerating chamber, carry out and regulated, thereby can prolong the compressor shutdown time, and can set the refrigerator of time-division operation refrigeration as required.This technical scheme mainly is to establish the cold-storage material in refrigerating chamber, between refrigerating chamber and refrigerating chamber the air channel is arranged, and utilizes fan to provide cold from refrigerating chamber to refrigerating chamber.Though this scheme can solve the problem of timesharing meter electricity, there are shortcomings such as control circuit complexity, refrigerator cost height, refrigerating taint of odour, the easy frosting of refrigerating chamber, can only on the computer refrigerator, use.And the operation that this scheme need increase air channel design, air channel fan has increased the energy consumption of refrigerator.The phase transition temperature of cold-storage material can only be placed on as the low-down environment of refrigerating chamber equitemperature in subzero.
The computer refrigerator of a refrigerating chamber band cool storage function has appearred on the market early stage, have timesharing meter electricity, sleep and power failure fresh-keeping function, implementation is that regenerator is arranged on the refrigerating chamber rear lower, be equipped with battery, having a power failure or releasing under the cold state, via the air channel cold is extracted into refrigerating chamber top from the cold storage chamber of refrigerating chamber bottom by fan and freezes, alleviate that refrigerator has a power failure or the temperature recovery of refrigerating chamber when releasing the cold operation state.This kind implementation has solved refrigerating chamber and has been communicated with problems such as the refrigerating taint of odour that brought, the easy frosting of refrigerating chamber with refrigerating chamber; but only on the computer refrigerator, use at present; still there are the following problems: needs increase small fan, battery and delay time accordingly or holding circuit; need carry out the air channel design; it is big to take up room; the phase transition temperature of cold-storage liquid is subzero; need increase the load of energy consumption, increase refrigerator during the small fan running; shorten temperature retention time, and fresh keeping time is subjected to the influence of accumulator electric-quantity etc.
As for the mechanical refrigerator of refrigerating chamber band cool storage function, then there are not relevant product and bibliographical information.

The specific embodiment
Embodiment one
The present invention accumulates cold, released cold quantity when temperature of refrigerating chamber raises by the refrigeration indoor design cold-storage device at refrigerator when refrigerator moves.In refrigerator cold-storage cell structure cutaway view shown in Figure 1, in cold compartment of refrigerator 1 back left side with a rectangle cover plate 2 (also can be designed to and cave in other supporting shape of portion) with built-in regenerator and the inner bag 12 portion's cap seal that caves in, four jiaos of blank cover are fixed on cover plate on the back inner bag with securing members such as bolt or screw 8 and (are stained with the mount pad that is connected and installed with associated fasteners in the inner bag corresponding position), regenerator-be arranged on inner bag 12 caves in portion and the formed indent of the cover plate cold storage chamber, cold-storage evaporimeter 3 (when adopting tube-in-sheet evaporator) is attached to the inner bag portion rear portion of caving in, be located between inner bag 12 and the heat-insulation layer 5, cover plate is concordant with refrigerating chamber inner bag rear wall (or to be allowed to have slightly outstanding, but must be lower than effluent trough outward flange place vertical plane, guarantee that condensed water and defrost water normally drop on discharge in the effluent trough.), the interior sight of refrigerating chamber is not constituted influence.In refrigerating chamber back bottom is the effluent trough that tilts from two side direction delivery ports 9, guarantees the normal discharge of refrigerating chamber defrost water.Referring to Fig. 2～3, in the portion of caving in of inner bag 12 regenerator 4 is housed, regenerator 4 is clipped between cover plate 2 and the inner bag 12, and cold-storage evaporimeter 3 is attached to the inner bag portion rear portion of caving in, and is located between inner bag 12 and the heat-insulation layer 5.When cold-storage evaporimeter 3 adopted threaded pipe types or inflation type evaporimeter, its position was slightly different, and at this moment, cold-storage evaporimeter 3 is arranged on inner bag 12 and caves in portion and the formed indent of the cover plate cold storage chamber, between regenerator 4 and inner bag 12.Cold-storage evaporimeter 3 can be made of one with refrigeration evaporator 7, also can connect by associated pipe.As can be seen, when two evaporator series connect (cold-storage evaporimeter can be connected before the refrigerator evaporator or thereafter), cold-storage evaporimeter and refrigerator evaporator are freezed synchronously by temperature controller control from the B-B cutaway view of Fig. 1.Wherein, the temperature-sensitive position of temperature temperature-sensitive head 6 in position range corresponding to refrigeration evaporator, can in ensconce the surface of refrigeration evaporator 7, also can external back inner bag surface (see figure 1) in refrigerating chamber.Perhaps, temperature temperature-sensitive head 6 is arranged on the cold-storage evaporimeter 3 also can.Two evaporimeters also can be to be connected in parallel, and two evaporimeter parallel connections also can reach the purpose of cold-storage.Also can adopt being connected of other evaporimeters such as cold-storage evaporimeter and refrigerating evaporator parallel connection or series connection (cold-storage evaporimeter can be connected before it or thereafter) connected mode.The present invention is arranged in the refrigerating chamber with regenerator with to the cold-storage evaporimeter of regenerator cooling, when outage, regenerator is directly to the refrigerating chamber released cold quantity, for the prior art scheme that regenerator is arranged on refrigerating chamber, has simple energy-conservation advantage, structurally omitted air channel and drive fan, and saved and being exclusively used in the battery that use as fan power supply the back that has a power failure.
Regenerator is moved to refrigerating chamber also needs to determine the regenerator proper working parameters, also promptly determines the phase transition temperature of cold-storage liquid.In the prior art, because regenerator is placed on refrigerating chamber or is equivalent between freezer environment indoorly, cold-storage liquid phase alternating temperature degree is at subzero lower temperature.Crossing low phase transition temperature is not suitable in refrigeration office work.National standard requires cold compartment of refrigerator each point temperature (according to three points for measuring temperature of standard-required setting) at 0 ℃～10 ℃, mean temperature requires can reach 0 ℃～5 ℃ in the cycle at the start-stop of refrigerator stable operation, but in actual use, for reasons such as power savings, the user generally can be arranged to temperature than 5 ℃ of high levels, and common temperature is set to 7 ℃～10 ℃.And fresh-keeping for short-term, refrigerator temperature is controlled at below 12 ℃ can reach fresh-keeping effect preferably.For the ordinary straight cold refrigerator; the wall of inner container surface temperature that directly is pasted with refrigeration evaporator is provided with the difference of gear and difference to some extent with controller; the refrigerator of stable operation at room temperature; at a start-stop in the cycle; its minimum temperature of the wall at refrigerator evaporator place can be to-10～-26 ℃; the highlyest then rise to 3 ℃～6 ℃; the storage temperature that just can guarantee refrigerating chamber meets GB requirement and all normally defrosts of each shutdown; improve the refrigerating efficiency of refrigeration evaporator; and its mean temperature is generally between-4 ℃～-9 ℃, with the temperature difference of about 10 ℃ of the temperature inside the box maintenances.
For guaranteeing the abundant cold-storage of cold-storage liquid, and consider the degree of supercooling of cold-storage liquid, the phase transition temperature of cold-storage liquid should be than refrigerator evaporator wall mean temperature height, and keep 4 ℃～6 ℃ the temperature difference, in order to prevent that the regenerator surface from freezing, frosting is too serious, the phase transition temperature of cold-storage liquid should be-2 ℃ and above being advisable simultaneously.For guaranteeing that temperature can remain on below 12 ℃ for a long time in the power failure rear cabinet, should guarantee that food has 8 ℃ the temperature difference in regenerator and the case, so the phase transition temperature of cold-storage liquid should be controlled at below 6 ℃.Sum up through test of many times checking, cold-storage liquid phase alternating temperature degree be 0 ℃～4 ℃ comparatively suitable, the power consumption minimum of the longest, refrigerator of the outage temperature recovery time of refrigerator this moment.
Referring to Fig. 4, cold storage chamber's cover plate 2 and regenerator 4 can be that independent parts also can be assemblies, when making assembly, with bolt 10 (or securing member of other type) regenerator and cover plate are fitted together, and then by securing members such as screw 8 the cover plate cap seal on the opening of cold storage chamber.The selection of fixed form and securing member can be according to situation appropriate design such as the phase transition temperature of used cold-storage liquid, appearance requirement, requirement of strength, as adopting plastic fastener, increasing decoration etc.For regenerator, both can be designed to an integral body, also can adopt the mode of a plurality of regenerator combinations.If the situation that cold-storage liquid leaks or regenerator damages, the user can dismantle regenerator voluntarily, more renew regenerator in use.
Because refrigerating chamber back inner bag and heat-insulation layer are provided with the cold storage chamber of caving in and cold-storage evaporimeter and regenerator are set, the insulation layer thickness at this place is thinner relatively, heat-insulating property is worse than other places, for reducing leakage heat herein, can locate to set up the VIP plate heat-insulating plates such as (vacuum heat-insulating plates) that heat-insulating property is better than common heat-insulation layer in the heat-insulation layer at this, the thermal conductivity factor of common heat-insulation layer be 0.017～0.022W/m
2.K, should be at the thermal conductivity factor of the VIP at this place plate less than the thermal conductivity factor scope of refrigerator heat-insulation layer.Thereby improve the energy-conservation level and the insulating power of refrigerator.
Further describe below in conjunction with the relevant issues of present embodiment regenerator, evaporimeter:
When 1) cold-storage material phase transition temperature is 0 ℃ of left and right sides, can select water as main cold-storage material, advantages such as glassware for drinking water has that thermal capacitance is big, latent heat of phase change big, is easy to obtain, with low cost, hygienic environment-protecting are a kind of important phase change cold-storage materials that relates among the present invention.Because its freezing point is 0 ℃, serious icing frosting phenomenon appears for preventing the regenerator surface, should take suitable insulation or defrosting measure during design: heat-insulation layer is arranged as filling out envelope in the cover plate.Its thickness choose reasonable is about 5mm～10mm, can adopt materials such as eps foam, EPE pearl cotton, also can adopt the PU foaming, carry out moistureproof processing the (the back heat-insulating property of avoiding absorbing water descends), and cold storage chamber taked certain seal approach, to avoid cover plate place knot bulk frost, influence the normal use of refrigerator.Temperature controller adopts the electric temperature regulator type, and temperature temperature-sensitive head 6 is arranged on the inner bag wall of refrigeration evaporator or its correspondence position.If cover plate does not increase heat-insulation layer; the icing phenomenon of not changing then appears easily; need take to force the defrost measure; specifically be on refrigerator usual pressure formula temperature controller, to increase to be provided with a semiautomatic defrosting button; can make the refrigerating circuit of cold-storage evaporimeter out of service; when cold storage chamber cover plate place occurs influencing the frosting phenomenon of refrigerator use, can press button and shut down defrosting, the back system recovery refrigerating operaton automatically that finishes defrosts.The freezer temperature control device can adopt the temperature controller of temperature difference type, and 6 of temperature temperature-sensitive heads are arranged on the cold-storage evaporimeter, correctly experience the regenerator temperature.Because refrigerator has cold-storage, releases cold function, defrost operation is little to the refrigerator temperature influence, and temperature of refrigerating chamber in refrigerator can be controlled in below 12 ℃.
2) phase transition temperature when cold-storage liquid is more than 0 ℃, when being lower than 6 ℃, cold-storage liquid adopts nontoxic, the safe aqueous solution or the hydrosol of polymer, the cover plate of cold storage chamber does not need to increase heat-insulation layer, adopt the temperature controller of electric temperature regulator type, its temperature temperature-sensitive head is arranged on the refrigerating chamber wall of refrigeration evaporator or its correspondence position.
3) refrigeration evaporator and the cold-storage evaporimeter setting of can independently connecting, also can make an integral body and be pasted on the inner bag wall, two evaporator area sums add about 20-60% than existing general refrigerator refrigerator evaporator, and the area of regenerator accounts for the 50-85% of evaporimeter.
4) the cold storage chamber position on the upper side, middle part that can be arranged on the refrigerating chamber rear wall can be left part or right part, also can extend to position, refrigerating chamber both sides (need set up condensed water and defrost water is discharged conduit, passage at the both sides corresponding site, it is confluxed to delivery port 9).The cover plate 2 of cold storage chamber can adopt and refrigerating chamber inner bag identical materials such as ABS, HIPS, also can adopt materials such as the high aluminium sheet of heat transfer efficiency, corrosion resistant plate, spray coating plate, in order to strengthen heat transfer area, outer surface can injection moulding or is extruded various decorative patterns or shape such as concavo-convex.
Regenerator thickness generally is designed to 28cm in 15～30cm scope, its shell can adopt plastics such as ABS, PP (for improving heat-transfer effect, also can adopt through the heat conductivility of modification heat-conducting plastic material preferably.), outward appearance is translucent or opaque, in order to strengthen heat transfer area, can blowing, injection moulding or extrudes various decorative patterns or shape such as concavo-convex in the surface.
5) when the phase transition temperature of cold-storage liquid is 1-6 ℃, can not need cold storage chamber's cover plate, but regenerator is made into the outward appearance part, directly utilize securing members such as screw to fix.
Embodiment two
Referring to Fig. 5, with placing in the heat-insulation layer, and regenerator 4 is clipped between cold-storage evaporimeter 3 and the heat-insulation layer 5 with regenerator and refrigeration evaporator, and securing member 8 inserts in the mounting groove 11 that is applied in cold-storage evaporimeter and the regenerator, with both clampings.Adopt this scheme refrigerating chamber inner bag back wall smoothly attractive in appearance, do not need existing inner bag adsorption mould, foaming mould are changed, cold-storage evaporimeter while and regenerator and refrigerating chamber heat exchange, improve heat exchange efficiency, evaporimeter decreases to the cold-storage effect owing to regenerator of the cold consumption of casing outside; Regenerator fully contacts with the aluminium sheet of evaporimeter in the released cold quantity process, and the heat transfer efficiency height is more even to the cold temperature of releasing of refrigerating chamber.But its shortcoming is that the user can not arbitrarily change, and can only be handled by the specialized maintenance personnel if regenerator breaks down.When the employing phase transition temperature is 0 ℃ cold-storage liquid, between refrigerating chamber inner bag and cold-storage evaporimeter, should increase certain thickness heat-insulation layer, perhaps adopt the semiautomatic defrosting mode.In being close to the rear portion heat-insulation layer of regenerator, increase insulation material such as the better VIP plate of heat-insulating property to improve the energy-conservation level and the insulating power of refrigerator.
Freshness preserving refrigerator while power cut-off of the present invention is mainly used on the mechanical temperature-control ordinary straight cold refrigerator. Tool Cost economy is arranged, and control is simple, cold-storage, the obvious advantage of energy-saving effect. Utilize the cold-storage material The principle of freezing by change of state realizes the refrigerating chamber cool storage function, slows down the refrigeration room temperature after refrigerator has a power failure Degree gos up, and keeps the freshness of food, in the area of often outage, the area of using electricity in off-peak hours, and can Prolonging temperature of refrigerating chamber gos up the time. Under normal temperature environment, when refrigerating chamber was unloaded, temperature was from 5 The time that ℃ is raised to 12 ℃ is more than the 15-24h, and general refrigerator only is 2-3h, and is holding When the phase transition temperature of cooler is 0～4 ℃, refrigerator energy-saving 5-10%. The technical program practical, And be not only applicable to mechanical temperature-control ordinary straight cold refrigerator, at computer temperature control refrigerator, air-cooled and direct-cooled ice Use on the case and have equally energy-conservation, as to have a power failure insulation effect.
