Cooling Tower Air Conditioning System
The main functions of cooling towers are as follows
Cooling: The cooling tower achieves heat dissipation by spraying high-temperature water or other liquids onto the packing layer, utilizing the heat exchange between water and air, thereby reducing the liquid's temperature to the set range.
Realize recycling: The cooling tower conveys the dissipated water back to the equipment for recycling, thereby reducing water consumption and improving the utilization efficiency of water resources.
Protecting equipment: In industrial production, some equipment needs to operate in high-temperature environments. However, high temperatures can have adverse effects on the equipment. Therefore, cooling towers are required to reduce the temperature of the equipment to the normal range to ensure its normal operation.
Energy conservation: Cooling towers can reduce the temperature of liquids to the set range by utilizing natural wind or forced convection through fans, thereby reducing energy consumption and improving energy utilization efficiency.
Technical parameters of BHD series of square cross-flow GRP cooling towers
1. The measuring points (R) and (T) are all in the direction of air inlet of the cooling tower. The equivalent diameter D=1.13 W L, among which, L and W are respectively the side length of the cooling tower.
2. It must be quiet around the cooling tower before determination of noise, the environmental noise should be 10dB (A) or more lower than the noise at the measuring point R under normal work of the tower, otherwise, it should be corrected. Please consult the technical personnel of the company for corrected value.
3. DF shown in the figure is the distance of equivalent diameter of the air outlet: 1.5≤DF≤5m.
Application
The Cross Flow cooling towers produced by GRAD have all passed the performance tests of the American Refrigeration Institute and obtained the CTI certification certificate. It can be widely applied in shopping malls, hotels, schools, libraries, office buildings, exhibition halls, airports, stadiums, subways, high-speed railways and other places with high requirements for noise control, providing supporting services for refrigeration chillers.
