Variable Refrigerant Flow (VRF)
ASHRAE Technical Committee 8.7

Meetings Information

Monday, January 25, 8:00 AM-9:30 AM

SEMINAR 21 (INTERMEDIATE)
Demand Response Using Variable Refrigerant Flow Systems

Track: Systems and Equipment
Sponsor: 08.07 Variable Refrigerant Flow

Chair: Harshal Upadhye, Electric Power Research Institute, Knoxville, TN

Demand response (DR) is defined as changes in electric usage from their normal patterns for the benefit of electrical grid in lieu of financial incentives by utility companies. Traditional DR mostly turns off the HVAC system completely or changes thermostats settings. Variable Refrigerant Flow (VRF) systems with their superior controls on compressors, fans and expansion valves can provide the kW reduction with minimal impact on customer comfort. This seminar provides an overview of DR capabilities of VRF systems and the benefits of providing DR with such systems.
