The device has the advantages of energy conservation and environmental protection, etc.

Description

technical field [0001] The invention relates to a composite energy system for refrigerating and drying agricultural products by using solar energy, and belongs to the technical field of energy refrigeration and heating. Background technique [0002] The traditional small and medium-sized commercial cold storage has a large initial investment, high operating costs, and requires a high level of operator skills. In addition, due to the diversity of land and climate resources, the production scale of farmers varies, and it is difficult for traditional small and medium-sized commercial cold storage to meet the requirements of different types of farmers. On the other hand, the use of conventional energy sources for drying agricultural products consumes a lot of energy. All of these limit the promotion and popularization of traditional cold storage and drying equipment in rural areas to a certain extent. Using solar energy to refrigerate and dry agricultural products can save con...

Problems solved by technology

Most of the reported intermittent refrigeration solar adsorption refrigeration devices use flat plates or metal tubes as heat collecting components, and the solar heat collection efficiency of the system is low.

Moreover, the solar adsorption refrigeration device using the basic adsorption refrigeration cycle cannot effectively utilize the solar radiation energy, the sensible heat of the adsorber and the adsorption heat of the adsorbent after the temperature of the adsorber drops in the afternoon.
