ANALYSIS OF HEAT PUMP SYSTEMS IN THE CANADIAN HIGH ARCTIC


This paper presents a sea water heat pump and cogeneration energy efficiency analysis conducted for the Canadian Forces Station Alert, located in the high Arctic. Three energy
efficiency strategies were evaluated for the station’s airfield located close to the Arctic Ocean. The station as well as the airfield annual fuel savings were compared for a sea water
heat pump system powered by the station’s main power plant, a small scale district heating system located at the airfield and a combination of four micro-cogeneration units and a sea
water heat pump system. The sea water heat pump system powered by the main power plant was determined to be the most energy efficient, reducing the annual fuel consumption
(electricity generation and space heating fuel) at the airfield by 27%. The small-scale district
heating system was the least energy efficient achieving only 14% fuel savings primarily because of the added electricity generating capacity not required at the station.
