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.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
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 conditioner as shown in the figure (II):
