ENERGY-SAVING COOLING CHAMBER FOR STORAGE OF AGRICULTURAL PRODUCTS USING NATURAL COLD

摘要

FIELD: cooling; agriculture.;SUBSTANCE: invention relates to cooling and storage of agricultural products and can be used in agricultural production and food industry. Energy-saving refrigerating chamber for storage of agricultural products with usage of natural cold contains heat-insulated room, cold accumulator, control unit, pipelines. In heat-insulated room there installed are tubular heat exchangers filled with ecologically clean coolant with low freezing point. Heat exchangers are connected by inlet and outlet pipelines through coolant pump and valves with cold accumulator, filled with coolant installed in open air and equipped with fan and air distribution pipe, forming closed circulation circuit of coolant in cold season. Heat exchangers are also connected by inlet and outlet pipelines through coolant pump and valves with plastic tubes filled with coolant and laid in buried in ground ice accumulator, frosting of ice in which is carried out in cold season due to freezing of water supplied periodically in it automatically from water line in volume, which depends on temperature of outdoor air with open hatches in cover of ice accumulator, forming closed circulation circuit of coolant in warm season. Control unit depending on temperature inside heat-insulated room, temperature of coolant in cold accumulator and temperature of outside air, controlled by temperature sensors by automatic switching of coolant and valve pumps, provides double-circuit cooling of air in a heat-insulated room for storage of agricultural products during the year.;EFFECT: higher storage capacity and cooling capacity, reduced operational and energy consumption for storage of agricultural products.;1 cl, 1 dwg
