How is the performance of the cooling pumps measure
Interestingly, cooling execution of ground source heat pumps is measured by the relentless state EER rather than a regular measure. The Vitality STAR project's base prerequisites for ground-source heat pumps are 21.1 EER for open-circle frameworks, 17.1 EER for shut circle frameworks, and 16 EER for direct extension (DX) units.
Example - Heat Pump Heating Season Performance Factor
For a heat pump deliver 120,000,000 Btu during the season when consuming 15,000 kWh the HSPF can be calculated as
HSPF = (120000000 Btu) / (1000 (15000 kWh))
= 8
