Ductless cold-climate heat pumps must have a Heating Seasonal Performance Factor (HSPF2) of at least 8.5 and a Seasonal Energy Efficiency Ratio (SEER2) of at least 15.2.
While conventional and cold-climate heat pumps can provide home energy-efficient heating solutions, cold-climate heat pumps are specifically designed to excel in low temperatures.
The vapor compression cycle plays a vital role in the functioning of heat pumps. In this cycle, a refrigerant fluid circulates through a closed circuit.
The compressor serves as the powerhouse of the vapor compression cycle, providing the mechanical work needed to move the refrigerant between the indoor and outdoor units.
