SPINCHILLER ZEPHIR ELFOSPACE CHILLED / HOT

2 WHAT S THE ENHANCED HYDRONIC SYSTEM The Hydronic System is a pre-configured modular system which is composed of three basic equipments: - ZEPHIR 3 stand-alone System; - SPINchiller 3 heat pump, air cooled or water cooled; - ELFOspace fancoils. SPINCHILLER ZEPHIR ELFOSPACE CHILLED / HOT WATER Feltre, International Sales Conference 215 The Clivet Enhanced 2

3 THE CONSIDERED CASE: THE BUILDING Case considered office building with three floors and a total net area of 6,6 m 2 The target analysis determine the energy performance of Hydronic System Clivet, in terms of: Primary energy consumption [kwhp] CO 2 emissions i [kg] Energycost [ ] Compare it with the traditional solution Feltre, International Sales Conference 215 The Clivet Enhanced 3
