Multisource heat pump system from design to operation: The case study of a new school building

Abstract

Heat pump features can take advantage of better sources than air, for instance the ground heat, solar heat and heat recovery. A multisource system aims to enhance the performances of the heat pump, leading to a significant amount of primary energy being saved. The present work shows data monitoring and analysis for a real working application in northern Italy, for 12 months. The energy balance indicates that the integration of different sources not only increases the thermal performance of the system as a whole but also optimizes the use of each source. © The Author 2013.
