Commissioning an Existing Heat Recovery Chiller System
Additional Document Info
Copyright 2018 ASHRAE. A heat recovery chiller (HRCHLR) is a special type of chiller. A chiller typically operates with a condenser water supply temperature of 55F to 85F (13C to 29C) and a condenser leaving water temperature of 60F to 95F (16C to 35C) (Heemer et al. 2011). This leaving water temperature is too low to be used effectively as a heating source for heating, ventilation, and air conditioning (HVAC) loads. However, a heat recovery chiller can be used to generate chilled water and work at condenser water temperatures of 155F (68.3C) and higher, which makes it possible for condenser water to be used as a heating hot-water source in HVAC systems.
