The extra capacity of the cooling tower is not automatically 25% and can vary with the system. These dissolved solids will therefore increase in concentration in the process water, until there is a Blow-down. One ton of refrigeration is 12,000 Btu/hr of heat. A cooling tower is designed to remove the total heat load that is extracted from the plant by reducing the CWR temperature to the CWS temperature. The cooling of the hot water was in the form of forced convection 3 by which ambient air at T1 was blown over the hot water and exited the cooling tower at some temperature T2. Cooling Towers dissipate heat from recirculating water that is run through cool chillers, air-conditioning equipment, or other process equipment. A cooling tower's job is to reduce the temperature of water through refrigeration. Cooling Towers dissipate heat from recirculating water that is run through cool chillers, air-conditioning equipment, or other process equipment. The number of baseline building chillers is determined in 6.8.2. Because of the inefficiency of the compressor it adds extra heat to the system that must be removed. A ton of air-conditioning is the rejection of 12,000 Btu/hour (12,661 kJ/hour). One tower is assumed to be matched to each baseline building chiller. This is discussed further in the sections below. Natural Draft Cooling Towersare usually used for large power plants and industrie… Previous. This reuse is particularly appropriate because the condensate has a low mineral content, and typically is generated in greatest quantities when cooling tower loads are the highest. So a one ton (1 TR) cooling tower can dissipate, at design conditions, 12,000 Btu's per hour. The equivalent ton on the cooling tower side actually rejects about 15,000 Btu/hour (15,826 kJ/hour) due to the heat-equivalent of the energy needed to drive the chiller's compressor.
