Comparison of Energy Consumption and Economic Factors between VRF Systems and Air-to-Water Chillers in Air Conditioning A Case Study of a Wedding Hall

This study seeks to investigate, compare, and assess the performance, energy consumption, and economic viability of two contemporary air-conditioning systems—Variable Refrigerant Flow (VRF) and Air-to-Water Chiller systems—when implemented in a substantial conditioned area, such as a wedding hall. The study entails the design and modeling of both systems under equivalent cooling load circumstances to ascertain their yearly energy consumption, system efficiency (COP/EER), and operational cost. The project will also include a life-cycle cost (LCC) study, which will look at the startup cost, maintenance costs, and energy costs during the system's lifetime. We will use HVAC design and simulation tools like HAP, Revit, or EnergyPlus to check how well the system works. For the economic assessment, we will use typical engineering cost analysis methodologies. The climatic data and load profiles will be derived from the prevailing weather conditions and occupancy trends of a standard wedding venue in Palestine (or the selected region). The result of this study will be a thorough comparison that helps people choose the best HVAC system for big halls and commercial buildings by balancing cost, comfort, and energy efficiency. The results may also help encourage the use of energy-efficient technology and sustainable design practices in the local construction industry.
