Explain why the outside air damper is typically nevercompletely closed, even when the outside air conditionsare not adequate to provide free-cooling.
HUMIDIFIER: MASS BALANCE On a hot summer day, the air is at 30.6 ° C and 80% relative humidity. The air conditioning in a building supplies 30 m3 / min of air at 13 ° C to keep the air inside the building at an average temperature of 24 ° C and 40% relative humidity. If the ventilation switch of the air conditioner is “open”, the air from outside enters the unit as shown in the drawing (I): The air conditioner cools the air to a temperature low enough to condense the required amount of water and reheat it to 13 ° C (unsaturated current), at which point it has the same absolute humidity as the air in the building. Calculate: a. the speed at which condenses water (kg / min) b. the temperature at which the air must be cooled to condense water at this rate. Do the calculations without using the psychrometric chart (although 1 atm of current pressure can be assumed). If the ventilation switch is closed, as normal, the air from inside the building would be recirculated in the air…
