Influence of Thermal Parameters on the Heat Load Calculation of the Building Using HAP Software

Abstract

The current world we are living in is energy driven and life seems to be almost impossible without it. Hence energy consumption is again another aspect which is closely related to power production process. The two important factors while designing comfortable air conditioning (AC) system is thermal comfort and energy consumption reductionIn this study, HAP software is used to analyse the inside air parameters in order to estimate the best possible condition which indicates minimum power requirement. The parameters on which the best suitable way to reduce heat inside the rooms chosen are as given follows - Walls orientations, windows orientations, climatic season, room level and thermal inertia inside the room. The paper presented is as per the standards provided by Indian standard of refrigeration and air conditioning (ISHRAE) which are in accordance with the climate of India. In particular, buildings require special air condition system and are mostly served by all-air HVAC systems in which control logics are fundamental to guarantee reliability and performance. Apart from this special care has to be taken while designing heating ventilation units in residential buildings. By comparing the output energy requirement of each room in different climatic seasons we can understand the behaviour of properties outside the room in order to minimise the total heat load. Also, it will help in understanding the foremost parameters that are responsible for the performance and functioning of air condition systems. This paper presents some results from operation data analysis of heat load for large residential complex based in Delhi. The main parameters of the energy consumption are shown to be dependent on room orientation and thermal inertia of room which is found to have a significant importance in the energy balance of the system.
