One Monitoring Device Design for Cold Storage Based on Energy Saving

Fresh agricultural products and rare Chinese medicinal materials have certain requirements on the temperature of cold storage in the store. In view of this problem, this paper designs a cold storage monitoring device to ensure the quality of fresh products, and solve the energy consumption in cold storage. The device includes temperature sensor, controller, alarm device, liquid crystal display, refrigeration unit and so on. Three aspects including control structure, air change device, refrigerant module are designed. This design can increase the refrigeration time of refrigerated items and the edible taste of food refrigerated items, reduce cooling energy consumption, it can be widely used in fresh products, Chinese medicinal materials, vegetables and fruits frozen preservation.
