Abstract
This study has been undertaken to look at some of
the air conditioning systems and select one for designing
the air conditioning for the second and the third floors
of the Mechanical Engineering Department building, Ahmadu
Bello University, Zaria. Many types of air conditioning
systems are available; an all-air single zone system is
selected and designed for the building.
The solar heat gains to the building are calculated
using Total Effective Temperature Differential method and
the cooling load estimatedrassuming a 12-hour operation of
the air conditioning system.
The supply air ducts are sized by the static region
whereas the return ducts are sized by velocity reduction
method.
A roof mounted air cooled condensing unit (Westings
house ST 020) together with a matching air handling unit
(Westinghouse AB 060) are proposed to air condition the
building.
