The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.
A typical evaporative, forced draft open-loop cooling tower rejecting heat from the condenser water loop of an industrial chiller unit Natural draft wet cooling hyperboloid towers at Didcot Power Station (UK) Forced draft wet cooling towers (height: 34 meters) and natural draft wet cooling tower (height: 122 meters) in Westphalia, Germany Natural draft wet cooling tower in Dresden (Germany)
In the present era, mechanical induced draft–type cooling towers are employed in cooling of water. Performance testing of cooling towers (both IDCT and NDCT) shall be carried out as per ATC-105 [4] at a time when the atmospheric conditions are within the permissible limits of deviation from the design conditions.
Refrigeration power and efficiency are low but Peltier coolers can be small, for small cooling loads resulting in overall low power consumption for a Peltier cooler with three stages. [9] [10] [11] For a Peltier cooler with seven stages, power consumption can be 65 W with a cooling capacity of 80 mW. [12]
Chemical additives to reduce these disadvantages may introduce toxicity to wastewater. Water cooling is commonly used for cooling automobile internal combustion engines and large industrial facilities such as nuclear and steam electric power plants, hydroelectric generators, petroleum refineries and chemical plants.
The cooling load [3] is calculated to select HVAC equipment that has the appropriate cooling capacity to remove heat from the zone. A zone is typically defined as an area with similar heat gains, similar temperature and humidity control requirements, or an enclosed space within a building with the purpose to monitor and control the zone's temperature and humidity with a single sensor e.g ...

Brine treatment is commonly encountered when treating cooling tower blowdown, produced water from steam-assisted gravity drainage (SAGD), produced water from natural gas extraction such as coal seam gas, frac flowback water, acid mine or acid rock drainage, reverse osmosis reject, chlor-alkali wastewater, pulp and paper mill effluent, and waste ...
