The difference between three types of condensers in refrigerated cabinets
2025-09-19
The condensers of cold storage, air curtain cabinets, cooked food cabinets, ordering cabinets, fresh meat cabinets, fresh food cabinets, island cabinets, refrigeration cabinets, freshness cabinets, and display cabinets produced by Henan Tianyang Electric Appliance Company can be basically divided into three types.
The condensers commonly used in supermarket freezers can be divided into three types based on their cooling medium and method: water-cooled, air-cooled, and water air combined cooling. In fact, these three types have significant differences, with different stored foods, temperature ranges, and working principles. Water cooling type: It uses water from the refrigeration unit in the refrigerator as the cooling medium. Supermarket freezers are devices that condense high-temperature and high-pressure gaseous refrigerants. Air cooled: A system that uses air as a cooling medium to cool the stator and rotor windings, as well as the stator core, of a generator. This system usually has two cooling methods: open ventilation and closed circulation. Water and air combined cooling type: Condensers that use water and air combined cooling method include two categories: water spray condenser and evaporative condenser. In these two types of condensers, the refrigerant condenses inside the tubes and the cooling water sprays outside the heat transfer tubes. In the sprinkler system, most of the heat released by the refrigerant is carried away by natural convection of air, while a small amount of heat is absorbed by the vaporization of water. Most refrigerators in supermarkets are air-cooled. Air cooled freezers are designed with microporous air supply, and there are also copper pipes with a large evaporation area inside the freezer. The refrigeration speed is fast, and it is not easy to dry, which can fully ensure the moisture and nutrients in the food, and the freshness display effect of the food is good. This type of freezer is usually used to store cooked food or fresh meat. The condenser commonly used in beverage storage freezers is a heat exchanger that releases heat from the refrigerant. The refrigerant vapor from the compressor through the oil separator enters the freezer condenser and transfers heat to the surrounding medium water or air. It condenses into liquid due to cooling, thereby reducing the temperature inside the freezer and achieving the effect of preserving beverages.
