Reversible heat pump (VRF) providing both heating and cooling

WhereΒ a reversible heat pump, which provides heating and cooling on reverse cycle with heat recovery, is used, the cooling capacity only should be used for the Direct Effect Life Cycle CO2e emissions (DELC) calculation.

The cooling capacity of heat humps is normally less than the heating capacity, so compliance against the criteria will be based on theΒ more challengingΒ DELC value calculated.
