OPTIMAL COMFORT CONTROL FOR VARIABLE-SPEED HEAT PUMPS.

Author(s) : MACARTHUR J. W., GRALD E. W.

Summary

AN OPTIMAL COMFORT CONTROL CONCEPT FOR VARIABLE-SPEED HEAT PUMPS AND AIR CONDITIONERS IS PRESENTED. THE CONTROL OBJECTIVE IS TO MAXIMIZE SYSTEM PERFORMANCE (COP) WHILE SIMULTANEOUSLY SATISFYING COMFORT CONDITIONS. PRELIMINARY TESTING OF THE ALGORITHM HAS BEEN ACCOMPLISHED BY SIMULATING THE CLOSED-LOOP CONTROL OF A VARIABLE-SPEED HEAT PUMP IN A HOUSE SUBJECT TO AMBIENT CONDITIONS. RESULTS PRESENTED FOR A SELECTED AMBIENT CONDITION SHOW THAT THERE IS AN INFINITY OF COMBINATIONS OF COMPRESSOR SPEEDS AND INDOOR AIRFLOW RATES THAT SATISFY THE COMFORT CONDITION, BUT ONLY ONE RESULTS IN THE MAXIMUM COP. THE OPTIMAL COMFORT CONTROL STRATEGY HAS BEEN TESTED OVER A RANGE OF LATENT AND SENSIBLE LOAD CONDITIONS.
