The effect of freezer on fresh products

The effect of freezer on fresh products

The dual refrigeration technology of the freezer solves the technical problems that are difficult to overcome by a single refrigeration method, so that there is no cooling blind zone in the cabinet. The 500mm super wide shelf provides customers with a larger effective display area and more inventory. Osram's special lamp tube placed at the front of each shelf enhances the display effect of the items in the cabinet. The integrated foaming of the freezer and the firm and reliable steel frame foundation make the cabinet better in heat preservation and the structure is more robust and durable. The inner bladder of the color steel cabinet with strong corrosion resistance increases the service life of the cabinet. The freezer's fully transparent glass side panels make the items in the cabinet clear at a glance and enhance the display effect of the items in the cabinet. The digital thermostat controlled by the microcomputer makes the temperature control of the items in the cabinet more accurate and the system more energy-saving.

The refrigeration load of the refrigeration room of the freezer is the heat that must be taken out from the refrigeration room per unit time; or the amount of cold that the refrigeration room obtains from the refrigerator in the unit time. The purpose of calculating the refrigeration load of the refrigeration room is to correctly and reasonably determine the cooling equipment load and mechanical load of each cold room. The cooling load of the cold room is not constant throughout the year, and its load size is affected by many aspects. For example, the changes in the external environment temperature, the amount of food storage in the cold room, the difference in the amount of cold processing of food during the off-season and peak seasons, and many factors in the operation and management methods. Usually, the calculation of the cooling load is one of the first tasks in the design of the cold storage refrigeration device. one. Therefore, it is very important for the refrigeration design to reasonably determine the refrigeration load of the cold room.

The most unfavorable working conditions should be considered when calculating the refrigeration load of the refrigerator. This is the principle of outdoor calculations. For rooms that transfer heat from indoor to outdoor, the outdoor temperature in the hot season should be considered; while for rooms that transfer heat from outdoor to indoor, the outdoor temperature in cold seasons should be considered. The cold rooms of cold storage are mostly of the type that transfers heat from indoor to outdoor
