Description of the invention: 'Technical field to which the invention pertains» - The present invention relates to a demisting device for use in a refrigerating and freezing apparatus, and more particularly to a method of using two correspondingly operated dampers for freezing The waste heat of the refrigeration equipment is recycled to perform a defogging device for defogging. [Prior Art] The application of refrigerated display cabinets is quite common today. Generally speaking, these 10 display cabinets can be divided into two types: closed and open. Open display cabinets are generally used in fresh supermarkets for storing fruits and vegetables. The food is immediately available for use by people, and its main feature is that there is no cabinet door design, and the cold air is circulated in the freezer by the air curtain to reduce the temperature of the article. The closed display cabinet has a cabinet door design (usually a glass door) that separates the freezing space from the atmospheric environment. The storage temperature range is also wide, and frozen foods such as beverages can be used from 5 ° C to -25 ° C. Condition food, ice, etc. Taiwan has an island-type climate, and the humidity is quite high throughout the year. The moisture in the air is easily condensed on the surface of objects with lower temperatures. Therefore, in order to prevent such condensation, a general refrigerator or display cabinet is generally designed to be heated by a heating wire to raise the surface temperature to make it difficult for the air to condense on the surface. For example, a heating wire is placed in the insulation layer of the refrigerator, or an electric heating layer is added to the glass of the closed display cabinet door, and electric energy is converted into heat to increase the surface temperature of the glass to prevent condensation of moisture in the air. This type of electrothermal heating not only increases the consumption of electricity such as refrigerators and non-plants (estimated to account for more than 20% of the total electricity consumption), but also often increases the surface temperature due to improper design and increases the load on the freezer. 200827647 _ In the cold storage cabinet, the air-cooled condenser is a heat source. The condensation temperature is usually designed at 50~55°C, and the inlet and outlet air temperature difference is about 5~10°C. Such hot air can be used to heat the display cabinet. The glass raises its surface temperature to prevent condensation of moisture in the air; if waste heat removal is adopted, the power consumption can be greatly reduced after being evaluated; in addition, in addition to saving electricity, waste heat can also achieve a part of environmental benefits because of cold The waste heat from the condensing unit (or radiator) of the refrigerated cabinet is often a factor contributing to the greenhouse effect. Therefore, the engineering community will now find ways to reuse it to minimize this undesirable effect. ® Republic of China Patent Bulletin No. 210748 discloses a hot air defogging display cabinet, which includes a split air duct and adjusting device to guide the hot air generated by the condenser to the glass surface of the cabinet door for defogging and raising the glass. The surface temperature prevents fog condensation. In this patent, the defogging will only be closed when the glass door is opened. However, in an environment where the humidity is not high and no fog is formed, the demisting device continuously blows the hot air on the glass door, which in turn causes the display cabinet to burden.
