There are many different types of cooling towers but the cooling tower working principles stay pretty much the same.Most cooling towers work based on the principle of “evaporative cooling“. Evaporative cooling is the process where warm water from an industrial process is pumped up to the top of the cooling tower where the water distribution system is. Before testing any evaporative condenser air pre-coolers, a set of baseline tests were obtained for a 4-ton RTU. An evaporative condenser is a device that converts refrigerant contained within a closed circuit from a heated vapor to a cooled liquid form by the evaporation of water sprayed on the exterior surface of the refrigerant tubing. evaporative coolers2, even though evaporative systems have a large potential to reduce both the peak electricity demand and the energy use associated with cooling. After the water has been chilled, it is distributed via pumps, pipes, and valves (the distribution system) to the loads, where a heat exchanger—for example, a cooling coil in an air-handler—transfers heat from the air to the chilled Petra Evaporative Condenser Rooftop Package Unit with Hermetic Scroll Compressors. c) Condenser Fan is used in air-cooled condenser to help move the air molecules over the surface of the condensing coil, hence rejecting the heat form the indoor to the space outside the building.
