| 19 | Main components 1. Coil: The coil is the main heat exchange surface of the evaporative condenser. It consists of a series of horizontal tubes with fins that increase the surface area exposed to the air and enhance heat transfer. 2. Fan system: The fan system creates a draft that drives air through the coil and provides the necessary heat transfer surface for evaporation, making it an essential component of the evaporative condenser. 3. Water distribution system: The water distribution system sprays water over the coil and uniformly distributes the water over its surface. Water distribution systems can vary from a simple gravity-fed system to a high-pressure pump system that delivers water to spray nozzles. 4. Sump: The sump is the collection basin that holds the cooled water and receives the recirculated water that is used to spray over the coil. 5. Pump: The pump is responsible for pumping the water from the sump to the spray nozzles, maintaining the required water flow rate. 6. Control system: The control system regulates the evaporative condenser’s fan speed, water flow rate and temperature, ensuring that the system operates efficiently. |
