Broadly speaking, the cooling tower is tasked with cooling the water circulating the condenser in air conditioning systems, industrial processes, power plants, refineries, and other industries.
The tower cools down the circulating water based on heat transfer via mass transfer, providing sufficient surface area for heat exchange between the water entering the tower and the air passing through, as well as slowing down the descending water by packings or other media (such as boards).
When selecting the cooling tower capacity, note that the maximum temperature difference between the input and output must be less than the difference between the input water temper...
Broadly speaking, the cooling tower is tasked with cooling the water circulating the condenser in air conditioning systems, industrial processes, power plants, refineries, and other industries.
The tower cools down the circulating water based on heat transfer via mass transfer, providing sufficient surface area for heat exchange between the water entering the tower and the air passing through, as well as slowing down the descending water by packings or other media (such as boards).
When selecting the cooling tower capacity, note that the maximum temperature difference between the input and output must be less than the difference between the input water temperature and the ambient Wet-Bulb Temperature (WBT). In other words, the minimum temperature of the cooling tower output must be more than the WBT in the space where the equipment is installed. On the other hand, the lower the humidity of the air where the cooling tower is installed, the lower the ambient WBT, helping provide colder output water.
Cooling towers can be categorized from different aspects as follows:
Notice: Cooling towers used in industrial or telecommunication facilities during the cold season are required to integrate electric heating elements in the basin at the bottom of the tower to prevent the water from freezing and damaging the equipment.
The normal loss of water in cooling towers can range between 0.2 and 0.3 lit/min per nominal ton of refrigeration (it must be noted that the loss of water depends on several factors including the relative humidity of ambient air, ambient temperature, and the temperature difference between the entering water and the ambient air).
For a cooling tower in the refrigeration cycle, the make-up water is estimated as follows based on the type of chiller compressor:
Chillers with screw compressors: 4gpm/100ton
Chillers with centrifugal compressors: 4gpm/100ton
Chillers with reciprocating compressors: 4gpm/100ton
Absorption chillers: 8gpm/100ton
In air conditioning systems, the water enters the tower (from the vapor compression chiller) at 33–35 °C and leaves it for the condenser at 28–30 °C. In other words, the range (the difference between the entering water temperature and the leaving water temperature) is approximately 4–6 °C.
The multi-stage thermostat: by installing a multi-stage thermostat at the cooling tower outlet to the chiller condenser, the temperature of the water leaving the tower (for the condenser) can be controlled by adjusting the slow-opening thermostat and changing the speed of the electric motor according to the command transmitted to the inverter.
In cases without a smart control system, it is necessary that at least one thermostat capable of commanding the fan motor to stop/start is installed on the cooling tower output line to the collector for times when the weather is moderate to offer further control over the temperature of the water leaving the tower.
In case of requiring consultation on the selection, calculation, and purchase of cooling towers contact our sales specialists at DamaTajhiz.
Under Cooling Towers category at DamaTajhiz.com—the first (from 2005) and largest online retailer for heating and cooling equipment in the Middle East (according to Alexa.com)—you can easily find a product that fits your requirements at the best price (best price guarantee) by browsing through the comprehensive descriptions provided, assured to receive original services and warranties.
Given the significance of the dynamic balance of the air circulation fan as regards the performance of the cooling tower and its direct impact on the durability of the fan and electric motor, make sure to have the tower installed perfectly horizontally and balanced to maintain the dynamic balance of the fan.
Efficiency is our motto, your benefits our priority
