Evaporative condensers are used for condensing vapor in mechanical refrigeration. They're also used for ammonia absorption refrigeration and are designed mostly to reduce scale buildup that develops within the machine through evaporative processes. They also have significant energy savings and use minimal energy.
Evaporative condensing saves more money than water cooling and air condensing. It’s also more cost-efficient than centrifugal fans. For those who have cooling needs, evaporative condensers cut how much water they must pump and also cut the chemical treatment requirements. Evaporative condensers need less labor than air-cooled condensers. They can run at lower temperatures than air-cooled condensers and can save 15 percent on electrical consumption due to the low-pressure condensation of refrigerants.
The fan section of the evaporative coolers is generally very sturdy, with an iron frame and galvanized steel sheet casing. The axial fans are heavy-duty. The motors are weatherproof. With other solutions, you often need annual cleaning. This leads to downtime. You don't have to do this with evaporative condensers. Evaporative condensers are also easy to maintain. They can run for a long time before they break down. Evaporative condensers don't cost a lot to install. They have modular designs, making them lighter and letting the owner no longer use expensive cranes when moving the condenser.
An evaporative condenser has moisture eliminators and a water spurge section. The water spurge headers release a fine spray of water over the condenser coils. Expanded plastic sections of pattern honeycomb are sent over the spray nozzle sections to keep water from carrying over because of fan discharge. Combined-flow technology reduces how much of the evaporation moves directly off the coil, lowering the chances of scaling and fouling. Air and water spray eliminate scale on dry spots.
Unlike the evaporative condenser, conventional evaporative-cooled condensers spray water on tubes containing very hot refrigerants, causing the water to evaporate and deposit scale on the coil. This reduces the heat transfer effectiveness of the system. By contrast, improved evaporative condensers use forced air convection to lower the temperature of the refrigerant before it enters the condenser coil, reducing how much water evaporates and reducing the mineral deposits on the coil. Water is sprayed over the condenser coil and condenser fans draw air across the coil, evaporating the spray and cooling refrigerant tubes until they reach the ambient wet bulb temperature. The evaporative condenser is 15 degrees F to 20 degrees F lower than the dry bulb.
Evaporative condensers cut the amount of refrigerants released into the environment. They also help the environment by minimizing energy consumption. The smaller energy consumption of the evaporative condensers comes from the lower operating temperatures. As a result, this device uses fewer natural resources.
