How does cooling technologies work?5 answersCooling technologies work by utilizing various methods to dissipate heat efficiently. These methods include mist generation to cool surfaces without causing damage, circulating cooling fluids through tubing and cold plates that engage heat-producing devices, employing Peltier devices with conductive shells and thermal bridges to cool goods, utilizing liquid hygroscopic materials for evaporative cooling, and employing refrigeration circuits to independently cool items like wine bottles. The technologies focus on maximizing heat transfer while ensuring efficient cooling and protection of surfaces or goods being cooled. By incorporating mist generation, fluid circulation, conductive shells, hygroscopic materials, and refrigeration circuits, these cooling technologies offer diverse and effective ways to manage heat dissipation in various applications.
What kind of refrigerators are used in restaurants?5 answersCommercial refrigerators used in restaurants include commercial walk-in refrigerators, counter type refrigerating show cases, and refrigerators specifically designed for dishes. These refrigerators serve different purposes and have different features. The commercial walk-in refrigerator acts as a space of mediation, secrecy, and pacification among restaurant industry workers. The counter type refrigerating show case is suitable for stores and small restaurants, with a transparent glass structure for displaying refrigerated food items. The refrigerator for dishes is designed to be placed on dining tables or cooking tables, allowing for easy access and rotation of dish boxes. Additionally, there are also direct cooling type refrigerators used in restaurants, which have separate freezing and refrigerating chambers for storing frozen and refrigerated food items.
How can the design of a multifunctional refrigerator be improved?3 answersThe design of a multifunctional refrigerator can be improved in several ways. One approach is to incorporate adjustable shelves and trays that can rotate freely, allowing for better space utilization and convenience in organizing items inside the refrigerator. Another improvement is the addition of a separating plate that divides the refrigerator body into separate refrigerating and freezing chambers, providing better temperature control and storage options. Furthermore, integrating advanced features such as an embedded system board, Wi-Fi module, touch screen, and control panel on the refrigerator door expands its functionality, allowing users to search for recipes, record memos, and monitor temperature and status easily. Additionally, the concept of a combined refrigerator, consisting of independent refrigerator body units that can be spliced together in various configurations, offers flexibility, energy efficiency, and personalized options for users. Finally, the use of a wave rotor type multi-stage refrigerator enhances refrigeration efficiency by utilizing unsteady pressure wave expansion and recovering expansion work.
