In the selection of the chiller for large warehouses or cold storages, the overall parameters of the chiller's technical parameters of the chiller and the main configuration of the chiller should be considered as a whole, and the overall needs of the cold storage or the warehouse should be selected. Type and installation. How to determine the air volume of the air cooler and its air supply distance must be carefully understood.
When selecting the Cixi air cooler for the cold storage, each engineering installation company will make the overall choice according to the specific needs of the project. The air volume of the air cooler is not as important as the cooling capacity of the air cooler. Party A tells you in advance about the purpose of the cold storage. You calculate the load and how much cooling it uses to offset it. Then, how big the fan is, the specifications of the fan and the library are also connection. The temperature difference is set by me, usually 5 degrees Celsius. The evaporation temperature is generally 10 ° C lower than the storage temperature. Assuming that the storage temperature is 20 ° C, the evaporation temperature can be 10 ° C. When selecting the cooling fan, one of the parameters has a great influence on the overall selection and cost. The inlet air temperature can generally be selected according to the inlet temperature equal to the storage temperature. The temperature difference between the inlet and outlet is generally about 5 °C. The previous time to do a project is because the inlet air temperature is not the temperature of the library temperature is lower than the storage temperature. Large, high cost. The temperature difference between the inlet and outlet of the cryogenic refrigeration air cooler is generally not higher than 2 °C, and the larger the air volume, the higher the wind speed and the smaller the temperature difference between the inlet and outlet. The high wind speed and high air volume heat transfer effect is good.
At present, most of the cold storages in the country are used as evaporators. In the selection of the air coolers, detailed calculations are also required in the air supply, and the gradient of the temperature is also to be considered as a whole. In the field of chiller production, Jiafeng provides customers with detailed parameters for reference according to the engineering requirements. If there is a special specification, the refrigeration cold storage Jiafeng can also customize non-standard refrigeration equipment according to engineering requirements.
