LOW TEMPERATURE DRYING AND REFRIGERATION SYSTEM CAPABLE OF DRYING AND REFRIGERATING FOOD MATERIALS STORED IN A STORAGE SPACE THROUGH A REFRIGERATION CYCLE

摘要

PURPOSE: A low temperature drying and refrigeration system is provided to include a damper operating refrigeration and drying modes so that the refrigeration mode is promptly changed into the drying mode, and vice versa.;CONSTITUTION: In case of a low temperature drying and refrigeration system, when a low temperature drying mode is operated, a damper (21b) formed in a drying unit (21) of an air moving unit (20) is operated and a storage unit (21a) of a condenser is open. At the same time, a drying damper (22) is closed to block the air moving unit. Therefore, air circulating inside the air moving unit moves only to the storage unit of the drying unit. As a result, air flows caused by the operation of a circulating fan (F) pass through a cycle of an evaporator (33), a condenser (31), a storage space (10), and then the evaporator. When a refrigeration mode is operated, the damper formed in the drying unit of the air moving unit is operated and the storage unit of the condenser is closed. At the same time, a return grill (23) and a condenser fan (31a) are open to inhale outside air, perform heat-exchanging, and discharge the outside air to the outside when the condenser is operated. Therefore, the air moves inside the drying damper when the drying damper is open. As a result, the air flows caused by the operation of the circulating fan pass through a cycle of the evaporator, the storage space, and then the evaporator.;COPYRIGHT KIPO 2013
