Summary

Heat pump system can save energy and installation cost and reduces CO2 emissions. In this study, a system identification of an air source heat pump system using R410A with a variable speed compressor was experimentally investigated under various ambient and indoor temperature and cooling or heating capacity. The experimental study was also performed under cold and hot climate conditions as well as normal ambient temperature in cooling and heating mode. A heat pump system was installed and tested in an environment chamber, where temperature and humidity are precisely controlled. Experimental points were selected under 28 conditions for each cooling and heating mode using center composition design method. Developed steady-state model predicted the experimental values within 10% error. In this study, we carried out in-situ performance test of the air source heat pump system. Further study will be carried out for fault detection and diagnosis for a heat pump system using developed system identification model.
