Commercial HVAC encompasses a broad range of technologies designed to control temperature, humidity, and air quality in non-residential buildings.
Systems range from small rooftop units to complex chiller plants, each engineered for specific load profiles and building types. Understanding how different system categories relate to one another is the foundation of effective equipment selection.
This session provides a high-level map of the commercial HVAC landscape and the key factors that determine which system type belongs in which application.

Variable Refrigerant Flow technology uses a single outdoor condensing unit connected to multiple indoor fan coil units through a refrigerant piping network. The system precisely modulates refrigerant flow to each indoor unit based on individual zone demand, enabling simultaneous heating and cooling across different areas of a building.
This inverter-driven approach eliminates the energy waste of on/off cycling, allowing the compressor to run continuously at the exact capacity required.
VRF systems are particularly well-suited to buildings with diverse occupancy patterns, high glazing ratios, or limited space for ductwork and mechanical rooms.
