In air-conditioning systems, air may be cooled and dehumidified by1. Spraying chilled water to air in the form of fine mist.2. Circulating chilled water or brine in a tube placed across the air flow3. Placing the evaporator coil across the air flow.Which of the above statements are correct?
During the evaporation cooling process, wet bulb temperature:
Air (at atmospheric pressure) at a dry bulb temperature of 40°C and wet bulb temperature of 20°C is humidified in an air washer operating with continuous water recirculation. The wet bulb depression (i.e. the difference between the dry and wet bulb temperatures) at the exit is 25% of that at the inlet. The dry bulb temperature at the exit of the air washer is closest to
During the chemical dehumidification process of air
If a mass of moist air in an airtight vessel heated to a higher temperature, then
