MODELING AND TESTING OF ROOM AIR CONDITIONERS IN HEATING AND COOLING MODES
This paper presents some simulation models and testing methods applicable to reversible room air conditionners. The first part of the paper describes the reference (“mother”) model. This model is an assembly of real and/or fictitious physical processes. It needs some tuning, in order to fit with the behavior of a given component. The tuning is made with help of manufacturer information and/or of test results. The second part of the paper presents the test method, some test results and reference model validation. The testing method described here is based on a double energy balance: one on refrigerant side and one on air side. The third part of the paper presents a simplified (“daughter”) model, reduced to a set of polynomial expressions, easy to use and to integrate into a global building simulation software.
