Boreal ® Heat Pumps
for Home
Boreal ® Air DC Series
While the Boreal ® proves to be an outstanding performer at heating your
home, it becomes even more efficient in the cooling mode. Most conventional
heat pumps provide air-conditioning by reversing the refrigeration cycle,
which requires the operation of the main compressor, pump and blower. Power
consumption in the cooling mode is the same or higher as in the heating
mode. With the Boreal unit however underground water is pumped directly
to the air heat exchanger coil.
There is no need to operate the compressor which consumes
approx. 80% of the power required in the heating mode since underground
water below 50°F. is already sufficiently cold enough to provide direct
air conditioning.
Central air conditioning and dehumidification is provided for less than
1/5 the cost of a compressor driven system. The capacity of the air-conditioning
section in a Boreal unit can be adjusted by varying the flow of water to
the cooling coil while that of a reversible unit is fixed to the capacity
of the heating section.
This unique feature is important since a reversible heat
pump large enough to supply all the heat in a Canadian home will generally
be greatly oversized in the cooling mode resulting in short cycling and
insufficient dehumidification of the air.
Since proper ehumidification of the air is essential
in the air conditioning mode, an oversized unit will fail to remove the
moisture required leaving the occupants cold and clammy, while the Boreal
unit can be tailored to remove the exact amount of humidity for comfortable
living.
The Direct Cooling Series (liquid-to-air) heat pumps
are designed to pump water from an open well and discharge to a return well,
pond, leaching field or other suitable return. The refrigeration circuit
is only operated in the heating mode while cooling is provided directly
by pumping cold well water to the special section of the air coil. Domestic
hot water is available during the heating mode with the purchase of an option
