Program summary: You will want to attend this seminar to hear HVAC industry experts present on changes to chillers and chiller plants, self-contained systems (rooftop units and packaged AHUs), and split systems such as VRF and other condensing unit/evaporation coil systems. The HVAC design for new and existing buildings with system upgrades needs to consider how space needs change with different equipment sizes, refrigeration sensors, and notification systems need to be provided (included with the equipment or not), special room construction needs, and so on. Retrofits for each equipment type and system need will be considered and discussed.
