Two major drivers influence the HVACR industry today: climate change and minimum efficiency regulations. As these sometimes complementing items shape the future of HVACR products, it is important to consider the reality of performance uncertainty in these products, specifically that of compressors (components) and liquid chillers (systems) when installed in the field. This seminar focuses on the test measurement uncertainty of compressor performance and field performance of liquid chilling systems and suggest possible solutions to the challenges these uncertainties cause for both HVACR manufacturers and users.
