Summary

Optimum control design has been an important aspect of improving the performance, efficiency and thermal comfort delivery of heat pump systems. Despite extensive research work on the development of advanced controls for heat pumps, most heat pump systems in the field still utilize simple controls such as PI (Proportional-Integral), cascaded PI, etc. One of the main reasons for this is the difficulty in assessing the actual improvement in energy performance and thermal comfort delivery of heat pumps with advanced controls. The current practice of performing extensive season-long field studies is timeconsuming and requires significant resources to carry out. Also, the performance results of these field studies are limited to the test building type and local climate conditions. To overcome this problem, a loadbased testing methodology has been developed to evaluate the performance of advanced heat pump control design for different building types and climate zones in a psychrometric test facility. This methodology provides a way for product developers to significantly accelerate the development of advanced control design and to obtain realistic performance assessments in a timely manner. In this paper, the load-based testing approach is demonstrated for performance assessment of two different control algorithms for a residential heat pump. In addition, the effect of equipment oversizing and undersizing on heat-pump performance is studied utilizing the test approach.
