Indoor temperature control and energy saving potential of an air conditioning system using pd controller

This manuscript presents a PD controller implementation to control the compressor speed of an air conditioning system according to cooling load to fulfill thermal comfort requirements with higher energy efficiency. An interface has been designed to monitor the experiment including the controller algorithm. The temperature settings of the conditioned space are 20, 22 and 24oC with internal heat loads of 0 and 1000 W. The experiments conducted indicate that the proposed technique has better temperature control and energy efficiency compared to the on/off controller
