How does the cooling by air conditioning affect the relative humidity?

shaik samdani

• Sep 5th, 2015

Simply RH is calculated as difference between dry bulb & wet bulb temps. The difference b/w these more RH% is more, its less RH% is less. When we apply A/C to dry bulb, temp decreases so RH% also decreases.

Relative humidity is ratio of mass of vapors in a given volume of air to the mass of vapors in the same volume at saturated point. With increase or decrease of % humidity or degree of saturation the relative humidity will be effected.

Role is to know the failure where it occurs, by calculating forces, stresses, strains, etc. and to load material in safety condition.
For this we have to know the property of material, thermal conductivity, mass, etc. and to optimise the cost of manufacturing, speed of production. so on.
