Description
Technical field
The present invention relates to a kind of Novel frost-free refrigerator-freezer refrigerating plant with solution dehumidification, belongs to refrigeration technology field.
Background technique
Cold in-cabinet temperature is low, and water vapour exists in liquid form mostly, these liquid are attached on refrigerator inner wall, and temperature reaches
When to subzero, ice crystal will be formed on inner wall, as soon as the date is long, thick bloom is formd in refrigerator.Especially
When we store aquatic products, frosting velocity can be accelerated.The phenomenon that multi-user is to refrigerator frosting is very worried, cannot only close again cold
Cabinet the more have to be tied the more thick because food can go bad by it.The harm of refrigerator frosting is not recognized, thus accidentally
Very big harm is brought for refrigerator and our life.1. according to measurement, when frosting thickness is greater than 10 millimeters in refrigerator, heat transfer
Efficiency can decline 30%, and so as to cause the decline of refrigerator duty, the compressor operating time extends, and power consumption increases.2. quick-frozen
Food food between five degree, can should preferably play fresh-keeping effect, make in rapid drop in temperature in 30 minutes to zero to minus
Its taste keeps original delicious, such as fish and shrimp.Frosting will lead to refrigerating speed decline in refrigerator, to be extremely difficult at 30 points
Zero Dao minus five degree is dropped temperature in clock, to influence the delicious degree of food.3. the temperature in refrigerator is very low, but only presses down
The reproduction speed of bacterium has been made, and bacterium cannot be killed, and the frosting in refrigerator will lead to cold cabinet humidity and increase, and be bacterium
Existence provides only condition.Imagine the food that us are saved in a space for being abound with bacterium.
Refrigerator defrosting is very urgent, by the experience accumulation of many years, has done defrosting for Journal of Sex Research, has summed up several points.
1. natural defrosting, eats up food in refrigerator, power supply is then pulled out, opens refrigerator door, the refreshing nature of ice is allowed to melt.It does so
Benefit is will not to injure refrigerator, and refrigerator inner wall will not be damaged because of expanding with heat and contract with cold suddenly, and harm is exactly that time-consuming.2. heating
Defrosting, pulls out refrigerator power supply, other heat sources are put into refrigerator, makes ice is refreshing to melt, and benefit is that time-consuming is short, and harm is to need it
His energy.3. tool eradicant eating pulls out refrigerator, most handy plastic spatula is clean by the refreshing shovel of ice in refrigerator, benefit be it is time saving, harm is
Arduously, and dynamics control is difficult, careless slightly to be possible to damage refrigerator inner wall.It causes any property loss.
As Publication No. CN102226608A disclose the present invention provide a kind of air conditioner except defrosting system, comprising: defrosting
Judgment module is exported and is instructed to the first defrosting that the bottom of air-conditioner outdoor unit is defrosted, or to outdoor unit of the air conditioner
The second defrosting instruction that entirety defrosts；First defrosting control module, instructs in response to the first defrosting, and control air conditioner enters
The the first Defrost operation mode to defrost to the bottom of outdoor unit；And second defrosting control module, in response to second defrosting
Instruction, control air conditioner enter the second Defrost operation mode to defrost to the entirety of outdoor unit.On the other hand, the present invention is gone back
It provides a kind of with the above-mentioned air conditioner except defrosting system.In addition, the present invention also provides a kind of Defrost methods of air conditioner.Compared to
The prior art, the present invention is under the air conditioner heat-production method of operation, and by adjusting the aperture of the electric expansion valve of air conditioner, utilization is cold
The temperature of matchmaker itself defrosts to outdoor motor spindle, is effectively improved defrosting effect, and then improve the heating performance of air conditioner.
And existing frostless refrigerator-freezer is to send cold wind method to refrigerator-freezer reefer space using air-cooled evaporator, enabling is seen not
See frosting evaporation tube, but be actually housed within wind-cooled evaporator surface or the frosting of sightless internal layer, only can't see,
Timing electric heating defrosting is set, and the present invention is overcoming the shortage of prior art, and proposes the refrigerator-freezer of real frost-free.
Summary of the invention
In view of the above deficiencies, the technical problem to be solved by the present invention is to provide one kind for above-mentioned state of the art
Using the dry adsorbent of solid to water vapor adsorption effect, air-cooler cooling is then entered back into, to refrigerator-freezer blows cold wind indoors.Specifically
Way is that condenser is arranged in refrigerator-freezer built-in space, and condenser pipe is with fin, and circulating fan sucking cold wind passes through side first
Heat exchange surface removes moisture, then enters back into air-cooler, guarantees air-cooler surface frost-free.The device has energy conservation, improves ice
The advantages of cabinet space air quality.
