Differentiating from an air-cooled version that rejects heat to an AHRI 95°F ambient temperature, Evaporative condensers use a network of sprinkle cooling nozzles to spray water over the condenser coil that evaporates and cools the condenser air down toward a typical AHRI ambient wet bulb temperature of … consumption can be saved due to low . Evaporative condenser In evaporative condensers, both air and water are used to extract heat from the condensing refrigerant. Evaporative Condensers. If additional sub-cooling is desired, to increase the available evaporating energy, this is best carried out in a dedicated sub-cooler situated after the condenser. For most industrial manufacturing, electric power generation and even air-conditioning needs, cooling towers are a critical element of the design. Part #WJ43X10003 $ 16.74. When warm, dry (unsaturated) air is pulled through a water-soaked pad, water is evaporated and is absorbed as water vapor into the air. Owners save money while conserving natural resources and reducing environmental impact. 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. There is a thin water film around the condenser tubes from which evaporative Figure 66F05 Evaporative condenser should be at higher level than its receiver.

Applications of Steam Condenser: The applications of Steam Condenser are listed below: Condenser like surface condenser is used in the thermal power plant to condensate the exhaust steam from the turbine. Course Contents Evaporative coolers, often called "swamp coolers", are cooling systems that use only water and a blower to circulate air. In these condensers, the water is sprayed from top part on a bank of tubes carrying the refrigerant and air is induced upwards. A typical one usually contains a hot primary coolant, a cold primary coolant, water sprinkles, cold water, and centrifugal fan in order for the system to provide the desired outcome. The objective of a mechanical refrigeration system is to remove heat from a space or product, and to reject that heat to the environment in some acceptable manner. Before testing any evaporative condenser air pre-coolers, a set of baseline tests were obtained for a 4-ton RTU. Water management of evaporative cooling units is essential and particular care must be taken to reduce the effects of hard water on the system. single condenser illustrated in Figure 3.
