Arctic Climate Horizontal Ground-Coupled Heat Pump.
Heating buildings in isolated communities of northern Quebec is done by the combustion of fuel oil. Ground-source heat pump is one of the potential technologies to replace oil furnaces but the performance of heat pumps is unknown in arctic to subarctic climate. The ground thermal properties and temp...

Heating buildings in isolated communities of northern Quebec is done by the combustion of fuel oil. Ground-source heat pump is one of the potential technologies to replace oil furnaces but the performance of heat pumps is unknown in arctic to subarctic climate.
