Cooling tower cooling technology design requirements - Database & Sql Blog Articles

1. Antifreeze measures should be used in cold and severe cold areas.

2. The following factors should be considered to determine the parameters and equipment specifications of the cooling tower cooling system:

1) The cooling capacity of the end coil should meet the winter cold load demand under the condition of the highest calculated water supply temperature and supply and return water temperature difference; the water supply temperature should be increased as much as possible, and the cooling tower should be extended. Cold time.

2) The maximum calculation of the cooling tower for the cold water temperature, temperature difference and the number of units used for cooling and cooling towers in winter, should be based on the cooling load demand, the calculated temperature of the air conditioning cold water, and the cooling capacity of the cooling tower under outdoor weather parameters in winter (provided by the manufacturer) Or refer to the relevant information), heat exchanger temperature difference and other factors, determined by calculation.

3) The open cooling tower should be equipped with a plate heat exchanger, which can consider the heat exchange temperature difference of 1-2 °C; the closed cooling tower can be directly supplied with water.

4) The specifications and number of circulating pumps for cold air conditioning in winter and cold water circulating pumps for plate heat exchangers should be matched with winter cooling conditions.

The above contents are compiled according to the problems encountered by the students in the actual work, for reference, if there is any problem, please communicate and correct in time.
