Air To Air Heat Pumps In Cold Climates

The winters in atlantic canada are among the coldest in the world and still heat pumps can operate efficiently during the vast majority of winter days.

Air to air heat pumps in cold climates.

By storing the heat energy we can distribute it to any source we want. Radiant floor heating cooling central air handlers for forced air split fan coils for individual room heating low temperature radiators and can also integrate to. Both system types are available with single and multizone indoor units. Our water heating system units can provide superior energy storage through a buffer tank.

While all heat pumps can provide heating for your home not all are ideal for extremely cold climates. Unlike any other cold climate heat pump system on the market our arctic heat pump can control your entire home heating and cooling needs including domestic hot water the heat pump integrates with multiple heating sources such as. Cchp replaces a furnace and air conditioner to provide year round heating and cooling and provides sufficient heat for approximately 50 to 70 of a household s annual hot water needs. While the study described in this article focused on single zone systems multizone systems are expected to perform similarly.

Ashp systems can be installed in different types of housing across a range of climates. They have done this through more efficient compressor design and control strategies that use multiple stages or variable speeds. For many homeowners across the u s cold climate air source heat pumps ashps can be a cost effective option for improving home comfort while delivering energy and cost savings that make their homes more affordable to live in. Cold climate air source heat pumps are available as both central ducted systems and ductless systems.

Air source heat pumps are generally sized to produce enough heat for 80 90 of the annual heating load and should be able to satisfy 100 of your heating load when temperatures are above 0 c. Unlike most other heat pumps on the market our cold climate heat pump uses an air to water principle. Market lists a heating capacity of 47 500 btu hr and a coefficient of performance of 2 55 at 0º outdoor temperature with 120º water temperature. Newer cold climate heat pumps have largely solved the problem of extracting heat from very cold air allowing them to operate economically down to 5 f or below.

As you can see the heating capacity of this air source heat pump drops off as the temperatures decrease. Their cold climate heat pump development and demonstration. The murb cchp is a multi unit residential building murb version of the a2a cchp. One unit currently on the u s.

Cchps operate with nearly 400 efficiency at 47 f or above. Low ambient air to water heat pumps are available. Some air to water heat pumps now are available that can operate at ambient air temperatures down to 13º.
