Air Conditioning system

The following must be done for designing Air conditioning system for one floor of a building. * Calculating the cooling load of each room + CFM by using a certain excel program I'll provide you with, after calculating the load and CFM insert the values as text in Autocad file which I'll provide you with. * Select Air Handling Unit or Fan coil unit of this floor + get its specifications (dimensions) and place it on the roof of the building for example by drawing it with its specifications. * Select chiller for the entire building which consists of 3 floors but since we are only interested in one floor then we can assume that the other 2 floors are having the same total load which we will multiply it by 3 to get the proper chiller then get the specification of the chiller and draw it in Autocad with the dimensions. * Select diffusers including return and supply of each room and show your selections by drawing it in Autocad with the specifications. * Do Piping and Ducting and show it in Autocad by drawing it * Do pumping and show it as well in Autocad. * Please be noted that I'll provide you with the architectural plan.
