Study of Cooling Loads with Energy Comparison & Cost Analysis for Optimal HVAC System Design

Abstract

The design and selection of an optimal HVAC (Heating, Ventilation, and Air Conditioning) system play a critical role in ensuring energy efficiency, indoor comfort, and cost-effectiveness. This study focuses on a detailed analysis of cooling and heating load calculations, followed by an energy consumption comparison and cost analysis for different HVAC system configu rations. The objective is to identify the most efficient and economically viable solution for a given application. The methodology includes estimating internal and external loads based on building design parameters, occupancy, equipment usage, ventilation requirements, and climatic conditions. Using these load profiles, alternative HVAC system options were evaluated in terms of energy demand, operational efficiency, and life cycle cost. The results highlight the significance of accurate load estimation in avoiding system oversizing or undersizing, thereby reducing both initial investment and long-term operational expenses. Findings from this study demonstrate that a properly sized HVAC system not only ensures thermal comfort but also contributes to significant energy savings and reduced environmental impact. The comparative cost analysis further provides a basis for decision making, enabling the selection of the most sustainable and cost-effective HVAC solution. This research emphasizes the importance of integrating load calculations, energy assessment, and financial analysis in HVAC design to achieve optimal performance and sustainability.
