Division 7 DETERMINING THE CO2 SAVINGS
United Kingdom
Prior to the launch of the official Type I test to be performed in accordance with Regulation (EC) No 692/2008, the type approval authority shall verify that the coolant temperature, including inside the enthalpy storage tank, is within ± 2 K of the temperature of the room. Where this temperature is not achieved, the methodology for determining the CO2 savings for the EST may not be applied.
The verification may be performed either by a measurement inside the Enthalpy Storage Tank (e.g. by means of a thermocouple), or by turning off the EST system before the conditioning procedure in order not to store heated coolant inside the tank. The temperature inside the enthalpy storage tank shall be recorded in the test report.
The relative CO2 reduction potential at different parking times shall be calculated using Formula 10.
