Which of the following process is called refrigeration? Cooling of warm air from 30 ºC to 10 ºC Cooling of the air from 10 ºC to 5 ºC Changing the temperature from 10 ºC to 22 ºC None of the above. 3. Which of the following statement is true for evaporative cooling of air using water? It is an adiabatic process. Enthalpy of air during evaporative cooling of air increases. The air can be cooled up to dry bulb temperature of the air. Relative humidity of air does not change during the process 4. Air conditioning for human comfort refers the Control of only relative humidity. Control of dry bulb temperature of the air. Control of purity of air. Control of temperature, relative humidity and quality of air along with proper distribu...
