MULTI-FUNCTIONAL REFRIGERATING SYSTEM FOR LOW-TEMPERATURE STORAGE, CURING AND DRYING AGRICULTURAL OR MARINE PRODUCTS USING COOL OR WARM AIR

摘要

PURPOSE: A multi-functional refrigerating system having drying, curing, and low temperature storing function for agricultural and marine products by using cool/warm air is provided to be capable of implementing drying, curing, and low temperature storing function with storing the agricultural and marine products in one storage, thereby being unnecessary for transporting the agricultural and marine products to various single-functional storages. CONSTITUTION: A multi-functional refrigerating system(100) for agricultural and marine products includes a casing(101) of which the side wall is insulated with a thermal insulating material. The casing(101) includes an exhaust duct(104), an exhaust inlet damper(105), an exhaust outlet damper(108), an air supply duct(113), an air supply outlet damper(115), a first ventilation opening(110), a first ventilation opening damper(111), a second ventilation opening(116), a second ventilation opening damper(117), more than one first air path(119a), a second air path(119b), and a sensible heat exchanger(119). The second ventilation opening(116) discharges exhaust air, which has passed through the exhaust duct(104), outside, or flows outside air in the exhaust duct(104). A compressor(120) compresses a low temperature-low pressure gaseous refrigerant into a high temperature-high pressure gaseous refrigerant. An expansion valve(122) adiabatically expands the refrigerant, which has passed through a condenser(121), into a low temperature-low pressure refrigerant. A cooler(123) cools the refrigerant, which has passed through the expansion valve(122), and the exhaust air, which has passed through the exhaust duct(104) and circulates in a storage(10).
