Cooling can be defined as lower than its ambient temperature for the temperature of the substance or medium. Refrigeration is the process of lowering the temperature and keeping it in a given space for cooling food, preserving certain substances, or providing an atmosphere that leads to a comfortable body. Storage of perishable food, drugs or other items is usually referred to as refrigeration under refrigeration. This refrigeration checks the bacterial growth and adverse chemical reactions that occur in the normal atmosphere.
The most important factor in refrigeration is the ambient temperature. In general, the temperature in the cold storage is higher than 1-2 ° C, which is the freezing point temperature of the stored fruits and vegetables. Stored products may not be frozen in cold storage. Thermal transfer is present in many cooling systems where heat transfer is widespread. The heat and mass transfer processes during the freezing process of fruits and vegetables were studied and the mathematical models of these processes were identified. The equation is solved for different refrigerated conditions.
The purpose of calculating the cooling load is to select the correct economic components such as compressors and condensers. Choosing an ideal cooling system requires a good calculation of the cooling load and must take into account all the cooling load sources. It is impossible to determine all the cold load inputs, so the cooling load may have some deviations, and the focus must be minimized.
The development of cold storage investment plans and feasibility analysis must first design cold storage. The location of the cold storage, the distance to the storage product, the time of shipment, the time to market, the storage product and the cold storage target must be determined. The goal of building cold storage is not only for specific products but also for different types of products. Some small cold storage design, rather than a large cold storage, is inevitably frozen by multiple products, minimizing energy costs and unpredictable.
Heat transfer: The calculation of heat transfer from walls, floors and ceilings requires the thickness and type of insulation material for the China cold room building, the structure of the building, the physical specifications of the cold storage, the ambient temperature, and the influence of the sun.
