Air Source Heat Pumps for Cold Weather
Heat pumps are not old technology that have been around for decades. The advantage of a heat pump is that it generates more energy than it consumes making it a more efficient device for heating and cooling than a traditional electric resistance element. Besides cost savings, a heat pump has the ability to supply both the heating and cooling needs of a building. This means you don’t need a separate air conditioner and heater to comfort your house or business.
What makes the cold weather heat pump different than a standard heat pump? It is the ability to perform even in -25 C temperatures!
How is this possible?
Air contains energy at any temperature above Zero Degrees Kelvin (-273.15 Degrees C or -459.67 F) this means that there is energy in -30 C air and there is 60 degree more energy in +30 energy. From a percentage stand point we could say there is about 22% more energy in +30 degree air versus -30 degree air compared to absolute 0. Harvesting the energy in this colder air is done the exact same way we harvest heat in any other temperature, through the refrigeration cycle. Freon is a gas that changes state at -29 C at 1 ATM. We can change the boil rate by adjusting the pressure. In the case of a cold weather heat pump the system is set up such that the energy in -25 C air is enough to cause vaporization of the Freon thus absorb the heat energy from the air and continue on to the compressor as a gas completing the refrigeration cycle.
Heat pump cycle
We offer 2 types of residential model heat pumps that are made in Canada certified for cold weather climate. These air source heat pumps are available in sizes up to 6 Ton or 72,000 BTU which is large enough to do almost any size residential or small commercial building.
We use Nordic Air Source Heat pumps manufactured in Canada. Unlike most other heat pumps these are specially designed for harsh cold -40 Canadian temperatures. Features such as: oversized outdoor evaporator unit for superior heating in extreme cold, intelligent defrost logic which reduces overall operating cost as the outdoor unit is not requiring constant defrosting. An unlike most split heat pumps, the compressor is located in the internal unit keeping it protected from the elements and keeping the Freon gas warmer for startup. Another key Feature is our cold weather air source heat pumps are Energy Star Certified to guarantee you the best ROI.
Air to Air models as well as Air to Water are available to cover any type of heating and cooling system. The Air to Water can also be used to heat pools. All units come standard with a built in hot water heat exchanger for domestic water heating.
