When evaluating the performance of agasheatpump (GHP), in addition to tests at set points in an environmental chamber, field tests are often useful to verify also the GHP behaviour at real running conditions.

Abstract

When evaluating the performance of agasheatpump (GHP), in addition to tests at set points in an environmental chamber, field tests are often useful to verify also the GHP behaviour at real running conditions. Indeed, GHP comfort, maintainability, serviceability and installation procedure information is also obtained by means of an in-situevaluation of its performance. In this work attention is paid firstly to the definition of the GHP performance parameters and to the consequent quantities to be measured and monitored. Therefore, this paper contains a short survey of measurement sensors suitable and convenient for an in-situevaluation of GHP performance as well as the related metrologicalanalysis (overall uncertainty evaluation). The present paper is only the first part of a wider study carried out by the authors. The experimental results of the in-situperformanceevaluation of a small-size GHP will be presented in further publications.
