NATURAL REFRIGERANT-BASED COOLING SYSTEM DESIGN REDUCES CARBON EMISSIONS IN HVAC TECHNOLOGY

Abstract

This study aims to analyze and design a natural refrigerant-based cooling system as an effort to reduce carbon emissions in HVAC technology without reducing system performance. The research method used is a qualitative method with a descriptive-exploratory design, which was chosen to understand in depth the system design process, technical considerations, and environmental implications of the use of natural refrigerants. This approach is considered appropriate because it allows for integration between theoretical concepts and sustainable cooling system design practices. The research was carried out at the Center for Research and Engineering of Air Conditioning and Refrigeration Systems, Faculty of Engineering, University of Indonesia, Depok. The research informants totaled six people who were selected purposively, consisting of HVAC system designers, operational managers, mechanical engineering academics, energy efficiency practitioners, environmental specialists, and technical policy analysts, who were selected because they had relevant experience and competencies. The results show that the design of a natural refrigerant-based cooling system has the potential to reduce energy consumption and carbon emissions without sacrificing the performance of the HVAC system. This study recommends the development of integrated system design as well as policy support to encourage the adoption of environmentally friendly refrigeration technologies.
