EXERGY ANALYSIS OF HVAC SYSTEMS FOR A HOUSE IN MONTREAL

Xin Wu, Radu Zmeureanu

Abstract: This paper presents the integrated energy, entropy and exergy (EEE) analysis of several design alternatives of the HVAC system of a house located in Montreal, for both peak design conditions and annual operating conditions. The results show that the HVAC system using electric baseboard heater and separate electric air ventilation heater has the lowest exergy efficiencies of 7.4% and 4.1% respectively under the above two conditions, while its energy efficiencies are 64.2% and 61.6% respectively under the same conditions. The HVAC system with the highest exergy efficiency of 23.2% (at peak design conditions) and 10.9% (at annual operating conditions) is composed of: radiant floor heating system; ground source heat pump; air-toair heat exchanger; earth tube heat exchanger; gasfired DHW heater.
