Description
Technical field
The present invention relates to the structure of refrigerator and build the adaptation technique field with external wall of house, relate in particular to refrigerator and temperature control method thereof in a kind of wall.
Background technology
1910 in the world the domestic refrigerator of First compression-type refrigeration in the U.S., come out, nineteen twenty-five, Sweden developed the family expenses absorption refrigerator, the fifties in last century, latter half, the Household hot refrigerator started to put into production ... develop into today, refrigerator is classified by refrigeration principle: (1) 91～95% refrigerator in the world belongs to compressor type refrigerator, and its refrigeration system is comprised of compressor, condenser, device for drying and filtering, capillary (throttling arrangement), evaporimeter; The motor compressor work done, cold-producing medium is flowed in system, the refrigerant vapour of HTHP (more than ten atmospheric pressure) is discharged into the condenser that is arranged on case shell outside, dispel the heat there, liquefy, cold-producing medium enters the evaporimeter in refrigerator with liquid form, in evaporimeter, evaporation is gasified and absorbs the heat in refrigerator, makes refrigeration in refrigerator; Cold-producing medium is general freon in the past, because it can damage the ozone layer, is eliminated gradually now, use other cold-producing mediums instead, but principle is the same.(2) absorption refrigerator accounts for market 5 percent, consists of the refrigeration system of sealing generator, rectifier, condenser, evaporimeter, absorber, lime set tank; Be filled with ammonia, water, three kinds of components of hydrogen in system, the wherein high steam of the ammonia liquefaction of dispelling the heat in case shell external condenser, liquid ammonia heat in evaporation gasification, respiratory box in evaporimeter in refrigerator, produce refrigeration.(3) the electric heating refrigerator is borne semiconductor refrigerator; It is to PN type semiconductor, passes to direct current, utilizes the pyroelectric effect of semi-conducting material to realize the refrigerator freezed.In addition, also have chemical refrigerator, electromagnetic oscillation refrigerator, adiabatic demagnetization refrigeration refrigerator, radiation refrigeration refrigerator, solid coolant refrigerator etc.
If press refrigeration modes (pressing air circulation mode in the case) classification of refrigerator, can be divided into direct-cooling type and air-cooled (claiming again indirect-cooling) refrigerator.Direct cooling refrigerator is by evaporimeter, and directly in respiratory box, heat is lowered the temperature; And evaporimeter and fan are housed in the air cooling type refrigerator case, fan air-supply, force the case inner air convection, promotes heat in the evaporimeter respiratory box, realizes uniform decrease in temperature in case.Divide if press refrigerator purposes (pressing Storage Requirement), can be divided into refrigerating box, household freezer and household refrigerator-freezer.Refrigerating box does not need for storing the food freezed, and sets approximately 4 ℃-5 ℃ of case temperature scopes; Household freezer is suitable for food product refrigeration, sets the case temperature below-18 ℃, (refrigerator temperature is set because storing, the frozen food difference, and refrigerator manufacturer difference has different, but substantially close.The above-mentioned setting case temperature of take in the application's discussion is example).Refrigerator also can be how many by chamber door, refrigerating capacity, Defrost mode etc. are classified, and do not repeat one by one.
There are some problems in the refrigerator prior art, wherein following 4 important, have much room for improvement:
The first, the refrigerator environment temperature concerns energy-conservation.
For refrigerator energy-saving, domestic consumers have noticed that refrigerator should be placed in indoor stow away from heat, ventilation shady spot.Brainstrust is pointed out theoretically; the environment temperature of refrigerator is that refrigerator environment temperature height has a direct impact refrigerator power consumption: the refrigerator environment temperature raises; refrigerator outwards heat radiation is slow; the temperature inside the box descends slow; and many from the cold that outwards scatters and disappears in case, keep the low temperature set in case more difficult, cause the refrigerator available machine time to lengthen; shorten downtime, causes that power consumption increases.The prompting of general refrigerator experimental data, the every raising of refrigerator environment temperature 5 degree Celsius, will increase approximately 25% power consumption.Otherwise the identical and refrigerator environment temperature of other physical conditions descends, refrigerator power consumption is by corresponding minimizing.But approximately 20 ℃-25 ℃ of Modern Family's comfort zones, domestic refrigerator is placed in indoor, and the refrigerator environment temperature is room temperature, sets the case temperature with refrigerator cold-storage case or refrigerator freezing case and compares the higher temperature difference of existence, the temperature difference that this is higher, the power consumption higher with refrigerator concerns.If the room temperature that the environment temperature of refrigerator compares decreases, will realize refrigerator energy-saving.
The second, the utilization of cold outdoor air.
If refrigerator is placed on indoor, approximately 20 ℃-25 ℃ of the room temperatures of Modern Family's comfort standard, indoor environment temperature is the environment temperature of refrigerator, should not change; Outdoor environment temperature is referring to table 1.Table 1 has been enumerated 10 major country cities (largest city or the capital that comprise 5 permanent members of the United Nations and all the other 5 developed countries) monthly mean temperature of annual 12 months in the world.
The annual monthly mean temperature statistical form in table 1. world Shi Ge major country city (degree centigrade)
It has certain representativeness for quite vast region temperature Change scope in the world.If the wherein temperature on average of some month in some cities of take is one " monthly temperature ", table 1 has been added up 120 " monthly temperature " altogether.Wherein
(1) 116 " monthly temperature ", lower than 25C, accounts for 96.6%;
(2) 104 " monthly temperature ", lower than 20C, account for 86.6%;
(3) 80 " monthly temperature ", lower than 15C, account for 66.6%;
(4) 60 " monthly temperature ", lower than 10C, account for 50%;
(5) 39 " monthly temperature ", lower than 5C, account for 33.3%;
(6) 22 " monthly temperature ", lower than 0C, account for 18.3%.
Visible, in the world, territory is in the overwhelming majority time immensely, and outdoor environment temperature is lower than indoor environment temperature.
Using cold outdoor air as the refrigeration source of refrigerating equipment, and especially, in northern area winter, some imaginations once were suggested for many years, were difficult to for various reasons obtain the coml extensive use.Need to explore a kind of more simple and easy structure and method, cheaply directly apply this large amount of naturally occurring cold outdoor air and participate in refrigeration for refrigerator.
The 3rd, refrigerator has occupied valuable careat and space.
Refrigerator is one of household electrical appliance that take careat and space maximum, and its front and back also need to retain certain distance with indoor wall or other furniture up and down in addition.In the situation that in the family room of big and medium-sized cities usable floor area and space increasingly expensive in short supply, both retained the function of refrigerator, economize out again its occupied careat and space, be that people's institute expects.
The 4th, refrigerator is also highfield.
According to expert introduction, during refrigerator work, be a highfield, the magnetic field maximum usually discharged with side after refrigerator or below.The different wave length that refrigerator discharges and the electromagnetic wave of frequency have certain influence to people's nervous system and physiological function; Electromagnetic penetration power is extremely strong, can see through body surface and go deep into deep tissues and organ, makes it to suffer damage.Reducing and avoid impact and the infringement of refrigerator magnetic field on human body, is also one of frequent problem of considering of people.
People once proposed respectively such-and-such scheme for this reason.
Such as the scheme had proposes refrigerating equipment is placed on to open air, or be arranged on window.But although the housing of refrigerating equipment can be used the quality material manufacture, expose year in year out after all the outdoor service life that affects; Temperature is suitable for use in about refrigerating equipment design temperature, and temperature is low, and the food freezed that do not need that refrigeration is stored can be frozen, the temperature height more things turn out contrary to one's wishes; Inconvenience, or affect indoor lighting and sights from refrigerator access food indoor.
Some schemes propose, with lower wall conduit, cold outdoor air is introduced to indoor connection refrigerator, the fitted shaft flow fan is squeezed into refrigerator by cold air, pass in case, again under ventilating fan coordinates through the blast pipe from drawing in case and another wall conduit by the Bas Discharged after replacing in case in outdoor atmosphere, circularly cooling like this.This air cooling system has certain-length into and out of pipeline, needs the brill wall to make under hole and manages, and operates simple and direct not.And refrigerator is placed in indoor caused variety of issue unresolved.
Some schemes propose compressor, condenser are separated from the refrigerator of routine setting, as off-premises station, are placed in open air, with the refrigerator remainder as indoor set, by the wall conduit wire, are connected, to reduce refrigerator indoor radiating, noise.But this minimizing is very limited, be not restricted to compressor and condenser because participate in the device of refrigerator heat radiation, in fact still be placed on the main body, machine chamber, air blast of indoor refrigerator so that air-flow guiding elements etc. are all relevant with the refrigerator heat radiation.And refrigerator is placed in indoor more caused problems and still exists.
Also have some schemes to propose refrigerator is embedded in the depression of wall; Perhaps embed in kitchen cabinet; Perhaps being built in two partition walls between room, is not the exterior wall in house, and in the partition wall be built between kitchen and parlor, the refrigerator opposed access door, therefore can be from kitchen and parlor access simultaneously food.These schemes can make indoor beautifying, save to a certain extent the careat space, but in fact refrigerator is also indoor, and the environment temperature of refrigerator or room temperature, also be difficult to tackle above-mentioned some problem.
In addition, for the impact of refrigerator electromagnetic radiation, the expert advice refrigerator is not placed on the place that the people such as parlor often stay, and is placed on kitchen and will avoids when refrigerator work near it as far as possible yet or avoid storing food when refrigerator work as far as possible; And through dust catcher commonly used, the position dusts such as refrigerator radiating tube are sopped up because dust more multiple electromagnetic radiation is just larger.But its effect is limited, for the solution of above-mentioned other problems also without benefiting.

(3) beneficial effect
The several aspects of harm and user, housing developer, refrigerator manufacturers and social several angle that beneficial effect of the present invention can be from the convenient utilization of refrigerator environment temperature and energy-conservation, cold outdoor air, increased indoor usable floor area and space, alleviated refrigerator magnetic field are inquired into.
1. refrigerator environment temperature and energy-conservation
From the region analysis-by-synthesis of the listed 10 city representatives of table 1., in 20 ℃-25 ℃ of generally held standard room temperatures, the monthly temperature of about 86.6%-96.6% lower than room temperature.First analyze the situation of outdoor temperature lower than room temperature at this, at this moment outdoor temperature lower than room temperature in wall the refrigerator environment temperature also lower than room temperature.Consider that brainstrust points out that the environment temperature of refrigerator (refrigerator environment temperature) height has a direct impact refrigerator power consumption, and the every raising of experimental data prompting refrigerator environment temperature 5 degree Celsius will increase approximately 25% power consumption, be placed in indoor conventional refrigerator environment temperature and be room temperature, higher than refrigerator environment space temperature in wall, conventional refrigerator power consumption is significantly higher than refrigerator power consumption in wall significantly.Visible, vast region temperature lower than room temperature over a long time in because refrigerator environment temperature in wall is lower than room temperature, so the present invention has realized refrigerator energy-saving.
From the region analysis-by-synthesis of the listed 10 city representatives of table 1., very little higher than the monthly temperature proportion of room temperature.In this short-term, even if longer temperature is higher than the period of room temperature in other regions, in wall, the refrigerator environment temperature can keep identical with room temperature.Take respectively high 1.8 meters, wide 0.6 meter of a kind of common vertical refrigerator, dark 0.6 meter and a kind of split type exist side by side refrigerating box and high 1.8 meters, wide 1.2 meters of household freezer, dark 0.6 meter is example, if the physical dimension of its refrigerator environment temperature space is than exceeding 10 centimetres, dark 10 centimetres, both sides from refrigerator body, each widely goes out approximately 5 centimetres, and in both walls, the volume of refrigerator environment temperature space is about respectively 0.28 cubic metre and 0.43 cubic metre.The ordinary residence that contrasts 100 square metres, high 2.2 meters of usable floor areas is the volume of 220 cubic metres approximately, in both walls, the volume of refrigerator environment temperature space is only occupied respectively approximately 0.1% and 0.2% of residence volume, make the so little by little volume space of ratio also keep room temperature, only need to increase energy consumption seldom, energy-conservation while particularly contrasting temperature lower than room temperature, the total energy consumption in refrigerator is long-time reduces.
2. the convenient utilization of cold outdoor air
In the present invention in body of wall hole rear wall and wall between the refrigerator rear portion distance very short, be connected in the often straight tube of tens centimeter length just of straight-through air inlet between the two, exhausting stub tube, simple in structure, assembling easily, easy to utilize.
More than ten atmospheric refrigerant vapours need be entered to condenser during the conventional refrigerator compressor operating, and continue to circulate in system, acting is many, and power consumption is higher; In refrigerator cold outdoor air refrigeration system when work in wall, air inlet, blast pipe is short and straight, and fan air blast, exhaust resistance are all very little, and power consumption is little.
When conventional refrigerator is enabled, need the empty van test running about 2 hours, until reaching in case after stable, could store food.The food of heat will cool just can put into case afterwards, otherwise can more increase power consumption.In wall, " refrigeration source " of refrigerator cold outdoor air refrigeration system is a large amount of naturally occurring cold airs, refrigerating capacity is large, cooling rate is fast first, therefore, when in wall, refrigerator is enabled, without the empty van test run then can directly store food, the food of heat also need not just can be put into case after cooling, and can directly put into wall refrigerator food precooling room, after the precooling in a moment of cold outdoor air refrigeration system, dump to refrigerator cold-storage case or household freezer in wall herein, very micro-on the power consumption impact.
3. indoor usable floor area and space have been increased
General refrigerator is placed in indoor, takies a part of indoor usable floor area and the interior space.Still take respectively high 1.8 meters, wide 0.6 meter of a kind of common vertical refrigerator, dark 0.6 meter and a kind of body split type exist side by side refrigerating box and high 1.8 meters, wide 1.2 meters of household freezer, dark 0.6 meter is example, its rear, top and both sides routine reserve the distance of some centimetres, to take respectively approximately 0.5 square metre and 1 square metre of interior architecture area, take respectively approximately 1 cubic metre and 2 cubic metres of the interior space.The room rate of every square metre of construction area of modern city house is often higher than refrigerator price several times.If refrigerator in the use wall, just this part occupied indoor usable floor area and the interior space can save out.
4. alleviated the harm in refrigerator magnetic field
The present invention is moved to hole wall by refrigerator from indoor, and it is all around around body of wall and ground, discharge the refrigerator of magnetic field maximum after side towards outdoor, thereby reduce and avoid impact and the infringement of refrigerator magnetic field on human body.
5. respectively from user, housing developer, refrigerator manufacturers and social angle analysis
For the user, refrigerator power saving in wall, refrigerating capacity is large, refrigerator magnetic field misgivings have been reduced or remitted, contrast is placed in indoor refrigerator and also can " many " goes out certain careat, space, and the room rate of the area that " many " go out is the price higher than refrigerator itself toward contact, cost-effective, the area of economizing out, space are also practical, should be welcome.
For the housing developer, in the construction of house design building, in the reserved body of wall room slightly wider than refrigerator of external wall of house so that and then in the finishing wall hole both without the bottleneck aspect engineering mechanics, also without the great number consumption of material funds very, increase the problem of cost and room rate, the body of wall room can be according to type of house, local climate and vegetable food market situation are reserved, with demand, adapt, as villa can be reserved the body of wall room of larger split type exist side by side refrigerating box and household freezer, apartment, residential building can be reserved the body of wall room of common vertical refrigerator, temperature is warmer, the gentle temperature in the abundant region of fresh vegetables supply is cold needs a large amount of refrigerating food storage region residents to use the refrigerator reserved body of wall room that varies in size to vary in size, when the wall Vacancy temporarily need not be fitted up even so, but shutoff does not take how many works and material yet, for the housing developer, basically have every advantage and not a single disadvantage, to become the bright spot of housing sale.
For refrigerator manufacturers, refrigerator power saving in wall, refrigerating capacity are large but manufacturing cost there is no obvious increase, and the workload that wherein traditional Refrigeration Technique is born reduces; the available machine times such as compressor shorten; lengthen downtime, makes the refrigerator life, and market prospects are good.And refrigerator manufacturers and the housing developer near mutually beneficial doulbe-sides' victory of cooperation aspect refrigerator in refrigerator environment temperature space and wall in wall.
For society, because refrigerator had become the requisite large household appliance of all Modern Families already, use amount is so big, and the social benefit of refrigerator energy-saving environmental protection is also of crucial importance, and in wall, the advantage of refrigerator will be taken seriously and promote.
