Design of II Stage Evaporative Cooling System for Residential

The control of indoor climate is important throughout the world, today the air conditioning engineers, architects, contractors; technicians are modifying indoor climates in homes, factories, commercial establishments, hospitals and offices throughout the world. The criticality of air conditioning became evident with the temperature and the humidity conditions became intolerable and industrial production become adversely affected and activities involving computers, electronics, aircraft products, precision manufacturing communication networks and operation in hospitals, in fact many areas of programming would come to a halt, so air conditioning is no longer a luxury but an essential part of modern living.

There are various types of Air conditioning systems depending upon the capacity of cooling required. For applications like big hotels, Super specialty Hospitals, cinema halls etc. where the cooling load is more than 50Tons, Central Air conditioning systems are used. In this system mainly the water is cooled initially then from water the air is cooled which then enters the cooling room. Hence the major part of the system is the piping which carries chilled water. In this paper calculation for the requirement for an Evaporative Cooling Machine sizing and Duct sizing has been performed. At the end of the paper the procedure of designing the 2 stage evaporative cooling system for a residential building can be done.
