Refrigeration and freezing walk-in cooler is generally divided into refrigeration and freezing, and the other is that refrigeration and freezing can be carried out at the same time. According to customer needs, it can be divided into different refrigeration rooms, mainly using water in solid-liquid phase change Release or absorb a large amount of latent heat at a time. At the same time, the large amount of latent heat released during freezing is used to maintain the fruits and vegetables in the warehouse from freezing damage; in summer, the ice is used as a cold source to maintain the necessary low temperature and high humidity conditions for fruit and vegetable storage.

　　refrigeration and freezing

walk-in cooler work defrosting is a refrigeration cycle, and heating is before defrosting. The principle of the freezer is: Freon absorbs heat from the outside and releases it into the room during the summer cooling. . At the same time, the hot air blown from the indoor unit during heating in winter, and the cold air blown from the outdoor unit, each manufacturer does everything possible to reduce the attenuation to the maximum level. Especially for fluorine system machines, this is not to say that fluorine system machines are not good and therefore must be defrosted. Have owners who have done fluorine system central air-conditioning find that when heating in winter, the indoor unit suddenly stops turning and sometimes it can still hear The machine has a   clicking   sound. The walk-in cooler water unit has a small temperature difference between the inlet and outlet water, and the indoor unit has a large air volume. And in winter, there will be no dry feeling like the fluorine system machine because of the high evaporation temperature of On Leon. It can play a great role in heating and defrosting. When the water unit is defrosting, let's talk about the heating of the water unit. Larger water units generally use two compressors.

　　 refrigerated and frozen walk-in cooler thermostat is a product designed for freezing walk-in cooler, etc. It has a beautiful appearance. The panel is separated from the control box and can directly drive a 2HP compressor. The user and manager menus are separated, which is convenient for ordinary users to simplify operations, while allowing managers to flexibly deal with different equipment conditions. The main products include microcomputer temperature and humidity controllers, temperature (data) recorders, embedded temperature display meters, refrigeration unit electrical control boxes, digital thermometers and hygrometers, intelligent halogen leak detectors, and more than 300 models in six series, which are widely used in food Cold chain, medical cryogenic equipment, HVAC, aquarium equipment and other industries.

　　The walk-in cooler has a wide range of uses, from supermarket food to industry to medical care. According to different cooling effects and use environments, walk-in coolers have their own structure and principles.

The internal principle of freezing and refrigeration is relatively simple: the moment it enters the freezer-refrigerator, the potential for low-temperature freezing and refrigeration is endless: more and more frozen and refrigerated products are sold in small pieces. Convenience store display cases all use distributed freezing and refrigeration. Liquid nitrogen boils and carbon dioxide sublimates. The energy (heat) required for this process is obtained from the food, which causes the food to be cooled and eventually frozen.
