A Theoretical Study to Determine Cooling Load of Proposed Bi-Level Building Based on CLTD Method

Continuous increase in atmospheric temperature because of global warming has caused reduction in human comfortness and to cope up with increasing global temperature or to achieve previous level of comfortness huge spending has to be done in form of air conditioning devices. To solve the above aforementioned problem, we have two alternatives electrical air conditioning and central air conditioning but electrical air conditioning will further increase the monetary spending because central air conditioning has high-power consumption and shorter duration of life. On the other hand, the effective design of centralized air conditioning system or a chiller unit will provide low consumption of electricity, minimal capital cost and will improve comeliness of a building. Central air conditioning can even solve the problem of oversizing and under sizing of cooling system. So, with the help of a proposed building layout and taking into account all possible heat source such as heat gain by individual, heat gain by fluorescent lamp, infiltration and heat gain by ventilation and all other possible heat source will be used to calculate cooling load due to different walls and roofs. At the end of this experiment, we will perform the same work of cooling load for two prominent Indian seasons for a bi-level building which is a part of an institute by using Cooling Load Temperature Difference (CLTD) method. And results obtained by aforementioned method are made to compare with the standard data obtained from various Fundamental Hand Books, such as by ASHRAE and CARRIER program and result concluded are satisfactory. In the end it is observed through this paper that the cooling requirement of monsoon is about 13% less in comparison to summer climatic condition
