The function of air conditioning system is a)-cooling and de humidification b)-cooling and humidification c)-all of these d)-heating and humidification

a). Cooling and dehumidification

Explanation:

Air conditioning means conditioning the air around. Air conditioners are meant for cooling and dehumidification of air. By dehumidification, we mean to remove water particles or moister from the surrounding air.

      This is a basic process by which a typical air conditioner undergoes.

When the moist air is brought near cold surface, it gets cooled below its dew point temperature. Thus some water vapour condenses into liquid and leaves as liquid from the air through the air conditioning process, thereby decreasing both the moisture content and temperature of the surrounding air.

Thus, the function of air conditioning system is to cool and dehumidify the air.
