The Impact of CO2-Based Demand-Controlled Ventilation on Energy Consumptions for Air Source Heat Pumps in Schools
Abstract
There have been increasingly growing
concerns for many years over the quality of the air
inside buildings and the associated energy use. The
CO2-based demand-controlled ventilation DCV offers
a great opportunity to reduce energy consumption in
HVAC systems while maintaining the ventilation
requirements. Thus, the paper discusses the
applications of CO2-based demand-controlled
ventilation DCV strategy for air source heat pumps
in schools, investigates its impact on the annual
energy consumption, and determines the potential
savings achieved in different USA locations. The
study includes detailed energy analysis on an existing
middle school through whole building simulation
energy software. The simulation model is first
calibrated and checked for accuracy using the actual
monthly utility data. This model is then used for
saving calculations resulted from CO2-Based DCV
and with various occupancy profiles and locations.
The results show a significant saving could be
obtained as compared to the actual operating
strategy implemented in the existing system and this
saving depends mainly on the actual occupancy
profile and building locations.
