Evaporative Cooler How It Works And Examples An evaporative cooler is a device that chills air by evaporating liquid water into water vapor. other names for an evaporative cooler are a swamp cooler, desert cooler, evaporative air conditioner, or swamp box. while highly effective coolers, evaporative cooling is not appropriate for every situation. for example, if you start with humid air. Direct evaporative cooling systems. in a direct evaporative cooling system outside air is pulled through a water saturated medium (typical cellulose) or air is sprayed with water and cooled by evaporation. the cooled air is circulated by a blower. moisture can be added to the air stream until saturation. dry bulb temperature is reduced.
Evaporative Cooler Parts Diagram The cooler pads, also known as evaporative media or cooling pads, are made of a porous material that absorbs water. as air passes through the pads, the water evaporates, cooling the air before it is circulated into the room. another important part of the evaporative cooler is the fan. the fan is responsible for drawing air into the cooler and. Drain and overflow tube. float valve. evaporative pads. distribution tubing. wire connection box. back to top. evaporative coolers, often known as swamp coolers, work by extremely simple physics: as water evaporates, it effectively "consumes" heat from the surrounding air. Connect the switch: if your swamp cooler has a 2 speed switch, connect the high speed wire from the motor to the terminal marked “hi” on the switch, and the low speed wire to the terminal marked “lo.”. ensure that the switch is properly wired and tightened. secure the ground wire: attach the ground wire from the motor to the grounding. Evaporative cooling can be visualized using a psychrometric chart by finding the initial air condition and moving along a line of constant enthalpy toward a state of higher humidity. [8] a simple example of natural evaporative cooling is perspiration, or sweat, secreted by the body, evaporation of which cools the body. the amount of heat.
