Évaluation des performances des systèmes de pompe à chaleur en annexe 52

Heat pump system performance measurement in Annex 52.

Numéro : 0303

Auteurs : GEHLIN S., SPITLER J. D.

Résumé

This paper presents an overview of the IEA HPT Annex 52, “Long term performance measurement of ground-source heat pump (GSHP) systems serving commercial, institutional and multi-family buildings.” Energy use intensities are a common system metric, but comingle the performance of the building envelope, occupancy effects and the system performance. The annex utilizes performance factors and a new boundary schema which facilitates characterizing the performance of different parts of the system. The annex delivered a library of quality long-term system performance measurements in the form of case studies, improved methodologies to better characterize system performance in larger buildings, and guidelines for instrumentation, uncertainty analysis, key performance indicators, data management and quality assurance.
This paper focuses on performance measurements of the heat pumps, covering both internal and external approaches, instrumentation and uncertainty guidelines. Though aimed at water-source heat pumps, the annex schema and guidelines are applicable to air-source heat pumps (ASHP) and air-conditioning systems also.
