Résumé

A heat pump or refrigeration unit has minimum 2 independent input conditions to fix per side: source and sink. For instance, water inlet temperature and mass flow rate, or air temperature and flow rate. The compressor frequency is an additional independent input. Therefore, the domain for the characterization of a modern unit with variable flow rates and compressor speed is a space of 5 independent variables. A test campaign following a full factorial plan with 5 levels per input requires 3125 test points. This paper presents first how the authors have studied the kind of multidimensional surface that could be characteristic of the performance of this kind of equipment. Then, the paper presents a methodology based on the Design Of Experiments theory to define the experimental test matrix which, with a low number of tests (around 30), provides the basis for an accurate characterization of the unit performance all over the entire domain by means of fitted polynomials.
