This design is the design of small cold storage refrigeation to the cold cold volume requirements, bined with the local climate, as well as the knowledge of the textbook theory to finish to meet the local needs of the cold the design, mainly for pressor selection, and cooler, evaporator design choices, and refrigerant quantity estimation and auxiliary equipment selection. Small cold storage for fresh agricultural nonstaple food and beverage refrigeration provided a space, to meet the fresh foods in refrigerated transport of fresh and frozen the people39。s living standard.
