Key design parameters of centralized heat pump systems

Presents the design parameters of eighteen centralized heat pump systems in a city in cold region of northern China and tests the practical operational energy consumption and energy performance. Compares the measurement results and design parameters. Discusses the rationality of design parameters of the projects and summarizes the typical problem of over-capacity selection in system design. Puts forward to predict the operation performance of the whole life time and make it as an important basis to evaluate the system design scheme and equipment selection.
