When choosing a cooling tower should first pay attention to the performance parameters given in the product sample and the gap between the actual performance of the product. Including the product sample of the untrue and engineering construction site of the meteorological conditions and product calibration performance of the test conditions are different factors. To be calibrated in accordance with the meteorological conditions of the project site. And should be based on the product's engineering application experience to take the appropriate adjustment measures. Sometimes have to use a larger margin factor.
Cooling towers are generally installed in the podium roof of high-rise buildings. Because of the distance from the main building is closer, so should also consider the cooling tower suction distance, fire, noise, drift fog and other issues. On the cooling tower suction distance national specifications for detailed provisions.
The choice of cooling water pump according to the cooling water system circulation resistance, water transfer height difference and free head decision, should not be rich too much. The flow rate of the pump should be determined by the temperature difference of the cold water after calibration. When multiple pumps work in parallel, they should be calculated and calibrated according to the parallel curve. Can not blindly by the number of units for water superposition.
On the cooling water system pool, the past in the design of cooling water equipment, the volume of the pool is mostly set by 10% of the cooling water (see air conditioning and refrigeration manual). This requirement is no longer applicable in the selection of water-collecting cooling towers. Water collection type cooling tower with its own water collection tank, its capacity is smaller, but the actual proof can also meet the needs of the cooling water pump work. The current air-conditioning cooling water system, daytime constraints by the building conditions, most can not set a large, in line with the 10% cooling water requirements of the water collection he.
Therefore, rely on the cooling tower itself and do a good job to maintain the water level and replenish the water collection tank can be. Relevant information recommended, the volume of the water collection tank is generally 2%-3% of the cooling water, building conditions permitting additional pool, its capacity should not be too large, do not need to be set by 10% of the cooling water. As long as it can accommodate the water volume of the cooling water system, to ensure that the normal start and work of the cooling water pump.
