Load-based testing is intended to better represent the energy consumption of HVAC equipment in real-world conditions and is used to develop a more detailed performance map for the equipment that takes into account the variation of efficiency with capacity. This type of testing is also intended to capture the performance impact of accessories and controls, like variable-speed fan control, staging and various thermostat control schemes. This seminar covers some experimental results with different types of residential HVAC equipment using a load-based testing approach and some of the implications for interested parties.
