Carbon footprint: heat pumps and refrigeration

Not a greenhouse-gas inventory, energy audit, carbon verification, or procurement basis.

Operation Electricity · fuel · steam Screen Refrigerant Leak · charge Separate Equipment Make to scrap ISO 14067
Only the operating stack is what this site’s screen compares. Refrigerant charge and the machine itself are separate.
Up Down Annual change Purchased energy × baseline factor Electricity × grid factor Pumps Defrost Standby Part load
The change can go up or down, pumps, defrost, standby and part-load stay outside the bars, and year and unit stay on the energy-factor page.
Chiller Once Heat pump Refrigeration Heat pump Twice
Count the same reject-heat packet once. A second tick, on both the refrigeration side and the heat-pump side, counts it twice.
Direction Screen Product footprint ISO 14067 Inventory ISO 14064-1
A direction stays in screening. A product footprint follows ISO 14067. An organisation inventory follows ISO 14064-1.
