Description
Technical field
The utility model relates to technical field of refrigeration equipment, particularly relates to a kind of refrigerator that independently can carry out gas regulation, relates more specifically to a kind of preservation device and the refrigerator that automatically can regulate humid gas.
Background technology
Controlled atmosphere storage more effectively delays the physiological aging process of fresh and alive food than refrigeration, and can keep the organoleptic quality of food in long-term storage preferably, as color and luster, hard brittleness and taste etc.Controlled atmosphere refers to by food storage in a relatively airtight storage environment, changes as required, the oxygen O regulated in storage environment simultaneously
2, carbon dioxide CO
2, ethene and nitrogen N
2a kind of method of stored product is carried out Deng gas component ratio.
The concrete method of controlled atmosphere is, changes the composition of normal air in storage environment, normally reduces the O in environment
2concentration also improves CO
2concentration, to weaken the respiratory intensity of fresh and alive food, delays metabolic speed, suppresses the change of chemical composition in microbial growth breeding and food, thus reaches the object extending storage period and improve storage effect.The result tested by controlled atmosphere is drawn, oxygen concentration is the controlled atmosphere storage requirement that can adapt to most of fruits and vegetables between 2% ~ 10%, such as green vegetables are optimum is the gaseous environment of the oxygen of 3%, the carbon dioxide of 4%, mushroom is optimum be 2-3% oxygen, the gaseous environment of the carbon dioxide of 10-13.Meanwhile, ethene is a kind of fruit-vegetable ripener, and fruits and vegetables can discharge ethene in the process of maturation, the impact of ethene can be subject to again and accelerate the aging of self simultaneously, therefore, in the process of storage, getting rid of ethene is a kind ofly avoid the effective means that the fresh food such as fruits and vegetables are aging.In addition, the temperature of controlled atmosphere can higher than the temperature of general refrigeration, some fresh and alive food can be avoided not adapt to low temperature and the chilling injury that occurs and freeze injury.
In addition, relative humidity is another factor affecting storage effect, maintain the steam pressure that higher humidity can reduce between product and air poor, thus reduce the moisture loss of product, fruits and vegetables need constant high humility and can not have the too many aqueous water overstock in storage, and it is shrivelled that constant high humidity environment can stop fruits and vegetables water loss to cause, but the aqueous water overstock can cause fruits and vegetables partial decomposition, and then develop into overall corrupt, cause its freshness date to shorten.
On existing market, refrigerator mostly is wind cooling refrigerator, and when the compressor is operating, fan starting, in refrigerator, moisture can be brought to the frosting of heat exchanger place by cold wind, and refrigerator cold-storage indoor humidity declines instantaneously, and humidity fluctuation in space is large, is not suitable for fruits and vegetables storage.In addition, fruits and vegetables in storage due to the high-moisture of self, stack up are deposited and refrigerator open time thermal shock cause condensation, local ponding can be caused to cause rotten, reduce fresh-keeping effect.
Provide a kind of wet-film humidifying system of wind cooling refrigerator in prior art, it solve existing refrigeration adding humidity project because of increase equipment, and take up space and raise the cost, humid control cannot be realized; Or need additional water source, use the problems such as inconvenient.This wet-film humidifying system comprises refrigerating chamber and refrigerating chamber, and connection air inlet duct and air-return duct form one-way circulation wind path between the two, blower fan and heat exchanger is installed in refrigerating chamber, humidification branch road is also communicated with between refrigerating chamber with refrigerating chamber, air-return duct upper bifurcation is communicated with the air inlet of humidification branch road, the air outlet of humidification branch road is communicated with refrigerating chamber, the crotch of air-return duct arranges selector switch, wet-membrane humidifier is installed in humidification branch road, install drip tray below heat exchanger, drip tray connects wet-membrane humidifier by aqueduct.But there is following shortcoming in it: complex structure, need refrigeration and freezing between humidification branch road is set, change structure excessive; The risk freezed is connected with refrigerating chamber.
