Did you know?
Heating seasonal performance factor (HSPF) is a term used in the heating and cooling industry. HSPF is specifically used to measure the efficiency of air source heat pumps. HSPF is defined as the ratio of heat output (measured in BTUs) over the heating season to electricity used (measured in watt-hours). It therefore has units of BTU/watt-hr. The higher the HSPF rating of a unit, the more energy efficient it is. An electrical resistance heat… WebU02674, Panasonic, CWHZ90ZA R32雪種變頻式冷暖窗口機 (1 匹 (無線遙控型)), 1 HP (Heat Pump model - Remote Control Model) Cooling/Heating Capacity : 9,100 Btu/h Annual cooling energy consumption (Based on 1,200hrs/h operation):343 kWh (Grade 2 Cooling/ Grade 1 Heating) Energy Label Equipped nanoe™X air-purifying system R32 …
WebSep 2, 2024 · For example, if a split system heat pump is rated with 14 SEER2 and 10 HSPF2, it will be modeled with a SEER and HSPF of: Cooling efficiency = 14 SEER2 = 14/0.95 SEER = 14.74 SEER. Heating efficiency = 10 HSPF2 = 10/0.85 HSPF = 11.76 HSPF. 2. Reference Homes with Federal Minimum Efficiencies.
