Description
Technical field
The present invention relates to technical field of refrigeration equipment, in particular to the refrigeration system and wind cooling refrigerator of a kind of wind cooling refrigerator.
Background technique
Currently, wind cooling refrigerator has become the main product of domestic refrigerator, traditional direct cooling refrigerator is compared, wind cooling refrigerator has
The advantages that refrigeration is rapid, temperature is uniform, automatic defrosting.But the automatic defrosting and the air duct circulatory system due to wind cooling refrigerator
Inherent characteristic, refrigerator inside water vapor in air constantly condense on an evaporator, and by defrosting process discharge refrigerator it
Outside, food in refrigerator, especially vegetable and fruit etc. are also resulted in be constantly in the environment of dry dehydration, causes wind cooling refrigerator
The easily air-dried problem of middle storage food.
Specifically, as shown in Figure 1, in the refrigeration system of traditional wind cooling refrigerator, each compartment (including refrigerating chamber, temperature-changing chamber and
Freezing chamber) hot wind (cold wind relatively described hereinafter) by air duct be transported to evaporator, carry out contact with evaporator
Thus heat exchange, hot wind become cold wind, meanwhile, the vapor in hot wind also congeals into ice on an evaporator to be retained down.Heat
The cold wind generated is exchanged, then is transmitted back to each compartment via air duct and freezes to food etc., the gas temperature liter after completing refrigeration
Height becomes hot wind, and hot wind passes through related air duct again and is delivered to evaporator, completes a heat exchange cycle.Long-term heat exchange cycle makes
A large amount of ice are condensed on evaporator, when ice gathers to a certain degree, refrigerator starts automatic defrosting mode, passes through high-power heating
Or the modes such as quickening air circulation make the ice-out Cheng Shui gathered, and by special drainage system, exclude outside refrigerator case.This mistake
Journey causes the moisture in each compartment inner air constantly to reduce, although there is the forms air exchange such as refrigerator open, supplement
Water deficient causes the food stored in existing wind cooling refrigerator is easily air-dried to ask to make up the moisture that system circulation is taken away
Topic.Meanwhile regularly heating defrosting also brings energy consumption burden to refrigerator, the power consumption for improving entire refrigerator is horizontal.
To solve the problems, such as that the food stored in wind cooling refrigerator is easily air-dried, in the prior art by using following two technology
Scheme solves: scheme one: being separately provided a sealing space, such as sealed drawer in refrigerator compartment (especially refrigerator room),
Sealed drawer and extraneous air exchange are reduced, to just reduce the loss of vapor in the sealed drawer, keeps local space
Interior humidity, achievees the effect that moisturizing.Scheme two: increase special humidification dress in refrigerator compartment or in independent moisture space
Set, for balance because system operation caused by moisture loss, achieve the effect that moisturizing.
But above scheme one has the following disadvantages: that space utilization rate is not high, in order to construct new partition space, causes
The waste in global storage space in refrigerator, while storage needs moisturizing food only in specified space；Moistening effect is bad,
When being switched to sealing space and accessing food, air exchange can also cause vapor to be lost.It is imitated simultaneously to improve sealing
Fruit increases mechanism and related function module also results in the rising of cost.Above scheme two has the following disadvantages: to be humidified because increasing
Device, refrigerator structure becomes complicated, the physical memory space becomes smaller, the raising of the rising of product cost and after-sales service difficulty；By
In carrying out forced humidification to refrigerator inside, refrigerator system is increased, such as the operating load of evaporator and compressor etc., improve
The energy consumption of entire refrigerator, while decreasing the service life of refrigerator.
