A Simplified Air-conditioning Systems Model with Energy Management☆

Abstract This research is a study of a split type air conditioner system demand response modelling. Air conditioners are commonly used in home and other buildings. Such systems mainly rely on air–cooled compressor for heat rejection process. Since air conditioners consume high electrical energy therefore, the management of their electrical energy consumption is also important. The main objectives of this research are to study and simulate an air conditioning system with electrical energy management by adjusting the temperature set point inside the building. The studies also include the factors that involved in air conditioner energy consumption such as the temperature inside the building, the temperature outside the building, insulation of the building and air flow etc., These studies are analysed and then applied to the air conditioners in a specific room to reduce their energy consumption without affecting people comfort in the building. The air conditioner model is simulated using MATLAB. The simulation results are compared with the results from measuring instrument. It can be concluded from the experiment that the results from MATLAB model and the results from the measuring instrument are consistent.
