Embodiment Construction

[0013] The present invention is further described in conjunction with the accompanying drawings and examples. The present invention is composed of heat pipe heat collection type solar adsorption refrigeration subsystem I, greenhouse type solar drying subsystem II, thermal insulation circulating water pipe 12, circulating water pump 14, blower fan 15 and air-water heat exchanger 16. The cold energy produced by the heat pipe heat collection type solar adsorption refrigeration subsystem 1 is stored in the ice storage tank 11 for supplying cooling to the miniature agricultural product cold storage 13, and the recovered heat is stored in the hot water storage tank 6. At night, this part of the heat is used to supply heat to the greenhouse type drying subsystem II through the circulating water pump 14, the air blower 15 and the air-water heat exchanger 16.

Abstract

The invention relates to a solar energy agricultural product refrigeration and dry compound energy device, which belongs to the technical field of energy refrigeration and heat supply. An adsorber (4) of a solar energy adsorption refrigeration subsystem first is internally provided with a heat transfer fluid tube (3), wherein, the upper end of the heat transfer fluid tube (3) is connected with a heat storage water tank (6), and the lower end of the heat transfer fluid tube (3) is connected with a heat pipe collector (1); the lower part of the adsorber (4) is connected to a condenser (9) and an evaporator (10) by a refrigerant pipeline (7), the evaporator (10) is arranged in an ice bank tank (11) of a miniature agricultural product refrigeratory (13); a hot water circulation path is formed by connecting the heat storage water tank (6) with a circulating water pump (14) and an air-water heat exchanger (16) through a heat preservation circulating pipe (12); and an air inlet (17) of a greenhouse solar energy dry subsystem second is connected with the air-water heat exchanger (16) by a ventilator (15). 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...
