There are two thermal calculations for the closed cooling tower. The first is the known water load and heat load. Under certain meteorological conditions, the area required for the closed cooling tower is determined according to the cooling requirements. The second is the known closed Cooling tower of the conditions, in a specific water load and heat load and weather conditions to calculate the cooling water temperature. In the design of the design of the use of closed cooling tower, it is closed by the cooling tower packing height, volume, air volume and known conditions after the cooling water temperature can meet the requirements.
There are many ways to calculate the closed cooling tower. In practice, some methods are more accurate
High, but the calculation of more complex, generally not used. Mechanical ventilation closed cooling tower calculation using Peng Jun enthalpy difference method or graphic method is more common. In the refrigeration unit, the direct use of mechanical ventilation closed cooling tower, according to the product samples calculated in the calculation chart.
The role of cold warehouses is to create a corrosive material can be stored in the low temperature environment, in order to maximize the maintenance of the original quality of food. So the inside and outside the Treasury to the Treasury temperature of the heat all removed to ensure the stability of the library temperature. In order to ensure this condition, it is necessary to have the corresponding refrigeration equipment, which produces the amount of refrigeration and should cause the library temperature fluctuations in the library inside and outside the size, as the basis for re-election refrigeration compressors and auxiliary equipment.
The cold load of the cold storage is not constant throughout the year, and its size is affected by the outdoor temperature, the food cooling process requirements, the number of cold processed products, and the operation and management methods. Therefore, in general, the maximum value of the cold cooling load is calculated first, and then the cold load of some cold spaces is multiplied by different coefficients according to the different conditions when determining the load of the cooling room.
