This system consists of heating and cooling equipments with automatic controls to produce comfortable conditions throughout the year. The atmospheric conditions are subjected to variations due to changes in weather. Therefore, it is necessary to have an air conditioning system, which is suitable for these variations without changing arrangement of existing components. Year round air conditioning fulfils the requirement of comfort i.e. “heating and humidifying in winter” and “cooling and dehumidifying in summer”.

Construction of Year Round Air Conditioning System
Year round air conditioning system consists of filter, heating coil, cooling coil and air washer.
Working of Year Round Air Conditioning System
In winter, the cooling coil is made inoperative. Heating coil operates to heat the air. Humidification is obtained with the help of spray type air washer (humidifier). In summer, the heating coil and humidifier are made inoperative. The cooling coil operates to cool the air. Dehumidification is obtained by cooling the air below its dew point temperature.
