Research on on-line monitoring of performance parameters for solar-assisted heat pump machine.

Author(s) : YANG Q., ZENG Q., LIU T., et al.

Summary

The paper introduces the sensing and measuring approaches of thermal performance parameters of experimental system of solar-assisted heat pump machine in view of practical design. Its control center is auxiliary modules including temperature module, which is used to monitor temperature, AD module for pressure and flux signals and touch screen for real time inspection. The principles of correlative hardware, the link interface and soft function are described, including sensor-interface circuit diagram, delay-PID control, data R/W conversion way, curve display and data register and so on. The results could be rather helpful to further the studies.
