The conditioning of air during winter season is totally different from summer air conditioning. It is necessary to heat air for comfort condition. But the R.H of the air decreases as it is heated, therefore , it becomes necessary to increase the R.H by humidifying the air. The air conditioning for winters heating and humidifying. The heating of air is generally done in two stages to simplify the controls.
The winter conditions at Aurangabad are 15*C and 70% relative humidity. The required comfort conditions are 24*C and 60% relative humidity.
The air is first passed through air filter to remove dust and then it is passed over heating coil. The temperature of air coming out of heating coil is controlled by the energy input to the coil. Then the air is passed through humidifying chamber where it is humidified with help of water sprays. The air coming of humidifier passed through eliminator to remove the water sprays. The air coming out of the humidifier passed through eliminator to remove the water particles. Then the temperature of air is further increased up to required temperature with help of energy input given to second heating coil. Then the air coming out of heating coil at required condition is supplied to an air - conditioned space.
