3.3. cooling seasonal performance factor
CSPF
ratio of the total annual amount of heat that the equipment can remove from the indoor air when operated for cooling in active mode to the total annual amount of energy consumed by the equipment during the same period
3.4 heating seasonal total load
HSTL
total annual amount of heat, including make-up heat, which is added to the indoor air when the equipment is operated for heating in active mode
3.5 heating seasonal energy consumption
HSEC
total annual amount of energy consumed by the equipment, including make-up heat, when it is operated for heating in active mode
3.6 annual performance factor
APF
ratio of the total annual amount of heat that the equipment can remove from and add to the indoor air when operated for cooling and heating, respectively, in active mode to the total annual amount of energy consumed by the equipment during the same period
3.7 total annual performance factor
TAPF
ratio of the total annual amount of heat that the equipment can remove from and add to the indoor air to the total annual amount of energy consumed by the equipment, including the active, inactive and disconnected modes
A.2 Measurement of the electric power consumption during the inactive mode
The unit shall be electrically connected to the main power source after shut-down for 6 h. Indoor and outdoor temperature of 20 °C condition shall be reached. The power consumption shall be measured for one hour after the temperature conditions are stabilized. The same test is repeated with the temperature condition of 5 °C, 10 °C and then 15 °C with the stabilization period of 2 h between each test. As a reference case, each power consumption value shall be weighted by weighting factors in Table A.1 and then integrated to obtain a weighted average inactive power consumption, Pia. The calculation of inactive power may also be undertaken for other climate conditions and operating schedules.
NOTE If the results of the tests at 20°C and 5°C are within 5% or 1W, then the tests at 15°C and 10°C are not mandatory. The average value of these results is used for the four considered temperature conditions.
