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
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
total annual amount of energy consumed by the equipment, including make-up heat, when it is operated for heating in active mode
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
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 of2 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 there sults 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.
The default mode hours for the calculation of reference total annual performance factor are shown in Table A.2. The calculation of total annual performance factor may also be undertaken for other distributions of mode hours.AS 3823.4.3 pdf free download.
