Cold Climate Heat Pumps (CCHP) Guide
Cold-climate heat pump (CCHP) is the latest development of high-efficiency air source heat pump design, which is mainly used to solve the heating problem in cold areas. Thanks to the inverter or variable speed drive compressor design, these heat pumps can achieve high efficiency even in winter.
CCHP operates at close to 400% efficiency at 47°F or higher. When the temperature drops to zero, CCHP will maintain an efficiency of about 200%. This means that every unit of energy consumed by CCHP can provide 2 to 4 units of heating energy. CCHPs are very efficient, they can provide up to 90% of space heating needs, with an overall seasonal efficiency of 250%.
Just like other heat pumps, CCHP doubles as a cooling system in summer.
The difference between CCHP and standard air source heat pump is:
1) It has a higher rating of the heating seasonal energy factor (HSPF).
2) Equipped with variable capacity compressors, making them incredibly efficient.
3) Install at a cross set point of approximately 0°F to ensure operation during the heating season.
4) Due to the inverter, the heat pump runs more quietly.
Different types of cold climate heat pumps (CCHP):
1. Mini split heat pump
* Heating and cooling specific rooms.
*No control. Installation is not expensive.
* Split type
1) Mini-splits can provide easy-to-install heating and cooling solutions for buildings without piping systems for use in rooms without air conditioning before.
2) Mini-splits are more affordable than other types of heat pump systems, so they can be used as a more accessible way for some building owners to strategically power up and reduce their carbon footprint.
3) In terms of refrigeration, the operating cost of Mini-splits may be 40% lower than that of indoor air conditioners of the same capacity.
4) Some of the latest Mini-splits models can provide space heating at very low outdoor temperatures without the need for fossil fuel backup.
5) Mini-splits can be used for 12-15 years, depending on the installation location and exposure of the outdoor unit.
2. Central pipeline heat pump
*Replace or add existing gas stove and pipes
* Can heat and cool the whole home/building
The ducted heat pump system uses the existing duct system to distribute air-conditioned air to your entire building or home for heating and cooling. They can also be retrofitted for use with your existing furnace. Customers considering the use of these systems should work with HVAC contractors with experience in control systems to program the central pipeline heat pump system to achieve efficient and energy-efficient operation.
