Commissioning an Existing Heat Recovery Chiller System Academic Article uri icon


  • 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 55°F to 85°F (13°C to 29°C) and a condenser leaving water temperature of 60°F to 95°F (16°C to 35°C) (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 155°F (68.3°C) and higher, which makes it possible for condenser water to be used as a heating hot-water source in HVAC systems.
