1. Product Introduction
1.1 Product Description
In our daily life, we often encounter hot weather that makes us feel uncomfortable, or food will be damaged after being stored for a short time, which reflects the importance of refrigeration devices in people's lives. When we feel the air is humid and hot, using air conditioning can lower the temperature and remove moisture for us. When we need to store food for a long time, the experimental refrigerator can keep the food for a longer time. These refrigeration devices have become an indispensable part of people's modern life. With the development of refrigeration, the refrigeration principle and these refrigeration devices have formed an independent subject knowledge system. It is necessary to understand how refrigeration devices refrigerate and understand the various refrigeration process failures of refrigeration devices.
ZMR001 is a workbench for studying refrigeration device components and failures. It is a device for training students of various vocational colleges or workers in related technical fields. It can study the refrigeration principle of refrigeration devices and the components required for refrigeration, as well as up to 15 refrigeration failures that may occur during the refrigeration process, providing learners with rich practical training content.
