Primary Energy Factor of a District Cooling System
Strojniški vestnik - Journal of Mechanical Engineering, 2016 The primary energy efficiency for various energy-related processes can be calculated using the primary energy factor (PEF). In this paper, the PEFs of district cooling systems (PEFDC) for different types of cold production are derived. These concern cold production with an absorption chiller driven by different available sources and cold production ...
