PRODUCT AND TECHNOLOGY TRENDS

Improving the energy efficiency of heating, ventilation, and air conditioning (HVAC) systems and restrictions on the use of hydrofluorocarbons (HFCs) with high global warming potentials (GWPs) are the current major issues for the HVAC industry. Air conditioning systems for commercial use are generally classified as direct-expansion (DX) systems such as variable refrigerant flow (VRF) systems, or hydraulic chilled water systems.
