Abstract
Since household appliances in recent years have been able to use inverters, an inverter driven air conditioner aiming at economical and comfortable air conditioning has appeared. Along with this, the development of a new controller unlike conventional ones, has become necessary. We have consequently studied a computer aided simulation technology for dynamic characteristics of air conditioners. The model of dynamic characteristics of air conditioners was divided into a refrigerating system and an air conditioning system. The statistical mathematic model was utilized for the former, while the physical model based on thermodynamics was realized for the latter. A Simulation using these models was performed. After the adequacy of the models was confirmed by experimental comparison, it was applied to evaluate the various parameters of the controller and to consider a new control algorithm. Simulation technology is thus an effective step for determining the control specifications.
