Which AC is used in cold storage?

Question

Accepted Answer

Cold storage facilities primarily use specialized refrigeration systems. These systems maintain low temperatures needed to preserve perishable goods - regular air conditioners do not. Direct expansion and indirect expansion units are common types of refrigeration systems. In direct expansion systems, refrigerant moves through evaporator coils inside the cold room and cools the air. Indirect expansion systems use a secondary coolant, such as glycol. Refrigerant cools the coolant first. Then the coolant circulates to maintain the desired temperature. This offers better temperature control for larger spaces. Of these systems components include reciprocating or screw-type compressors. Condensers with air-cooling, water-cooling, or evaporative cooling are also important. Expansion valves as well as fans for air distribution also form part of them. The most common refrigerants in cold storage are R-22, ammonia next to R-404A. For industrial cold storage, high-capacity air conditioning units, designed for that purpose, see use. Automated scheduling and load management promote energy conservation also dependability.
