12/11/2023 0 Comments Swamp cooler dew point chart![]() ![]() The passenger compartment has a volume of 2 m3 and requires 5 air changes per minute to keep the interior of the automobile at the necessary degree of comfort. The air returns to the car at a temperature of 10Â☌ and a relative humidity of 90% (Figure Q1). In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants."Īt 1 atm, 27Â☌, and 50% relative humidity, atmospheric air from the inside of a car enters the evaporator part of the air conditioner. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation), which can cool air using much less energy than refrigeration. ![]() Evaporative cooling works by employing water's large enthalpy of vaporization. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Problem 5 (20 points) "An evaporative cooler (also swamp cooler, desert cooler, and wet air cooler) is a device that cools air through the evaporation of water. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants."Ī) Sketch a psychometric chart indicating the cooling process line, inlet, and outlet.ī) Using the given psychometric chart, complete the table below with the respective minimum theoretical temperatures that could be achieved using evaporative cooling to provide environmental control and comfort".Īverage Daily Design Dry Bulb 7:30 am 1:30 pm 7:30 pm 7:30 am 1:30 pm 7:30 pm SOLVED: Problem 5 (20 points) "An evaporative cooler (also swamp cooler, desert cooler, and wet air cooler) is a device that cools air through the evaporation of water. ![]()
