What is a Cold Climate Ducted Heat Pump?
In cold climates, heating accounts for 61% of the energy use of ordinary
households. In commercial and institutional environments, space heating
accounts for 56% of energy use.
Cold climate heat pumps can heat and cool in extreme climates. –30 ⁰C is used for heating and 46 ⁰C is used for cooling. Compared
with traditional electric heating systems, heat pumps will save you up to 70%
of energy consumption.
In addition, by using heat pumps for energy-efficient heating, you can
also effectively help slow down global warming.
Ducted Heat Pump
The ducted heat pump looks like a central air conditioner. It has an
outdoor unit and a coil located in the domestic plumbing system.
In summer, the heat pump operates like a central air conditioner. The
circulating fan passes air through the indoor coil. The refrigerant in the coil
absorbs heat from the indoor air and then pumps the refrigerant to the outdoor
coil (condenser unit). The outdoor unit discharges any heat in the home into
the outdoor air and at the same time cools the home.
In winter, the heat pump reverses the direction of refrigerant flow, and
the outdoor unit absorbs heat from the outdoor air and transfers it to the
indoor coil in the piping system. The air passing through the coil absorbs heat
and distributes it to the home.
Mini split (no pipe) Heat Pump
The working principle of the Mini split heat pump is similar to that of
a central pipe heat pump, but it does not use a piping system. Most mini split
or ductless systems have an outdoor unit and one or more indoor units (machine
head). The indoor unit has a built-in fan that can move air to the coil to
absorb or release heat from the coil.
A system with multiple indoor units is usually required to heat and cool the entire home. The mini split heat pump system is most suitable for homes without piping systems, such as homes with hot water boilers, steam boilers or electric skirting heaters. The mini split system is also very suitable for homes with open concept floor plans, as these homes require fewer indoor units.
