Taking the existing refrigerated display case as an example, the temperature of the food in the display cabinet must be kept below C. Therefore, the operating temperature of the refrigerant is about. c to 1〇. Between c, and most of the time, the evaporator connected to the refrigerant is maintained below "c, so the coil temperature of the inner evaporator is lower than the dew point temperature of U, so that the sickle in the air is smashed into frost.

It is necessary to increase the spacing between the fins in order to improve this phenomenon and reduce the 孰= of the evaporator and the surrounding air! The distance between the Guangzeng and the Korean film is the same as that required for the cabinet. Due to the various shortcomings of the above-mentioned frosting, the exhibition $_ (about 30 to 40 minutes) is carried out & the ride between the seats..., the defrost of the t-gen, the general defrost operation 1269856 stops the operation of the compressor but maintains the operation of the fan. The defrosting operation is carried out by infiltrating the indoor air outside the cabinet. The defrosting operation of the display cabinet causes the following disadvantages: 1 · The temperature of the food in the display cabinet rises or even deteriorates during the defrosting period, resulting in a greatly shortened shelf life of the food. . 2 • The compressor must be stopped once every time the defrost is performed, and the compressor's repeated stop will shorten the life of the compressor. 3 · During defrosting, the air in the display cabinet has a higher saturated vapor pressure due to the temperature increase and absorbs the moisture in the outside air. When the defrost process is finished, the temperature inside the display cabinet drops again, and the air in the cabinet The saturated vapor pressure is reduced and excess water is released, which penetrates into the food package with lower temperature and condenses or frosts inside and outside the food packaging, causing the appearance of the food to be indecent and seemingly flawed, reducing the customer The desire to buy. SUMMARY OF THE INVENTION Therefore, the inventors of the present invention have developed a frost-free refrigerating and freezing apparatus in view of the drawbacks of existing chilled refrigerating display cabinets and the adverse effects on foods during defrosting, and the improvement thereof. The main object of the present invention is to provide a frost-free treatment method for use in a refrigerating and freezing apparatus, which uses a dehumidifying apparatus to ensure that the air passing through the evaporator in the refrigerating apparatus has a desired dry state, so that when the dry air passes through When the evaporator is cooled by the evaporator, the surface of the evaporator is not frosted, thereby eliminating the defrosting procedure of the evaporator and avoiding the temperature fluctuation caused by the defrosting affecting the preservation of the food. In order to achieve the above object, the present invention is mainly to provide a frost-free treatment method for use in a refrigerating and freezing apparatus, which establishes a 1269856 cold air circulation passage and an adjacent hot air discharge passage in a refrigerating and freezing apparatus. And a dehumidification device is disposed in the cold air circulation passage and the hot air discharge passage, the dehumidification device dehumidifies the air in the cold air passage to generate a dry air, and the dry air passes through an evaporation in the cold air passage After being cooled by the evaporator and after the amount of moisture adsorbed on the dehumidifying device reaches a certain amount, the waste heat in the refrigerating and freezing device is used to heat the air in the hot air discharge passage, and the heated air is passed through the moisture of the dehumidifying device. Saturated to remove the moisture in the dehumidification device and regenerate the dehumidification function of the dehumidification device. By the above technical means, the dehumidification wheel of the present invention can absorb excess moisture of the air in the cold air circulation passage to cause a dry air which passes through the evaporator, is cooled by the evaporator and does not frost or condense on the surface of the evaporator. Therefore, when the evaporator temperature is below 〇°c, the frost-free state of the surface can be maintained, so that the temperature in the refrigerating and freezing device is maintained at a steady state without repeatedly raising and lowering the temperature, so that the food can be maintained at a stable preservation temperature. And effectively maintain the freshness of the food; in addition, the inside and outside of the food packaging will not condense or frost, thereby maintaining the aesthetic appearance of the food to enhance the customer's desire to buy food.
