Cooling Load Estimation for a Multi-story office building

Sahu , Sandip Kumar (2014) Cooling Load Estimation for a Multi-story office building. MTech thesis.



Human comfortness is essential now a day because of the improvement in life style and increasing atmospheric temperature. Electrical air conditioning machines are not most suitable for large buildings because of the higher power consumption and shorter life. Central air conditioning is more reliable for easy operation with a lower maintenance cost. With large buildings such as commercial complex, auditorium, office buildings are provided with central air conditioning system. Educational and research institutions also need human comfortness, as the population of student community increase year by year. The effective design of central air conditioning can provide lower power consumption, capital cost and improve aesthetics of a building. This paper establishes the results of cooling load calculation of different climate conditions by using CLTD method for a multi-story building which is a part of an institute. Cooling load items such as, people heat gain, lighting heat gain, infiltration and ventilation heat gain can easily be putted to the MS-Excel programme. The programme can also be used to calculate cooling load due to walls and roofs. And results were compared with the standard data given by ASHRAE and CARRIER Fundamental Hand Books, and results are satisfactory. It is also seen that in this paper cooling requirement of summer is about 9 % more as compare to monsoon for climate condition of Rourkela.
