Air conditioner model study using Athens load control experiment data

The behavior of a single air-conditioner unit has been evaluated using a simple model based on heat transfer and heat balance equations. Specifically, the dynamic model of D. Bargiotas and J.D. Birdwell (1988) is applied to predict duty-cycle variations and the effect of load control intensities on the interior temperature. Variations of indoor temperature and humidity are evaluated from the model for actually recorded outdoor conditions on a hot and humid summer day. Simulations for three cases have shown that the intensity of direct load control should be carefully selected to avoid undesirable increases in indoor temperatures. Actual data obtained from the Athens Automation and Control Experiment (TN, USA) are used to compare the simulation results
