Air conditioning is a complex field that encompasses the simultaneous management of all mechanical parameters essential for the comfort of individuals, animals, and industrial or scientific processes. The system consists of parts and equipment organized to meet different conditions required for comfort in residential and industrial settings. Increasing demand has led to rapid growth in air conditioning systems and manufacturers, with a focus on selecting the right system for energy efficiency. Improving energy efficiency in HVAC systems is crucial due to rising energy consumption over recent decades, which raises concerns about future energy crises and environmental impacts. Measures aimed at improving energy efficiency in buildings are intended not only to reduce energy costs but also to offer additional benefits such as lower maintenance requirements, improved comfort, reduced electricity use for lighting and appliances, and enhanced property value. HVAC systems can be categorized by their method of heating control within conditioned spaces. This analysis guides on selecting suitable systems based on specific application needs while considering short-term and long-term goals. Achieving efficient HVAC systems requires enhancements in integrated mechanical components design as well as optimal plant operation — contributing to significant reductions in power consumption considering that buildings account for over 40% of total power consumption in developed countries. This Special Issue focuses on advancing understanding related to efficient HVAC systems including cooling technologies, component design optimization strategies like regenerative processes, and effective handling of thermal storage aspects.
