  "heading": "Seasonal space cooling energy efficiency of comfort chillers and air conditioners when driven by electric motors:",
  "text": "(a)For the purposes of the measurements of air conditioners the indoor ambient temperature shall be set at 27 °C;\n(b)While establishing the sound power level, the operating conditions shall be the standard rating conditions set out in Table 16 (air-to-air heat pumps and air conditioners), Table 17 (water/brine to-water comfort chillers), Table 18 (air-to-water comfort chillers), Table 19 (water/brine-to-air heat pumps and air conditioners);\n(c)The active mode seasonal energy efficiency ratio SEERon shall be calculated on the basis of the part load for cooling Pc(Tj ) and the bin-specific energy efficiency ratio EERbin (Tj ), and weighted by the bin-hours the bin conditions occurs, taking into account the following conditions:\n(1)the reference design conditions set out in Table 24;\n(2)the European average cooling season set out in Table 27;\n(3)if applicable, the effects of the degradation of the energy efficiency caused by cycling depending on the type of control of the cooling capacity;\n(4)the reference annual cooling demand QC, shall be the design cooling load Pdesign,c multiplied by the equivalent active mode hours for cooling HCE as set out in Table 29;\n(5)the annual energy consumption for cooling QCE shall be calculated as the sum of:\n(i)the ratio of the reference annual cooling demand QC and the active mode energy efficiency ratio SEERon ; and\n(ii)the energy consumption during thermostat-off, standby, off and crankcase heater mode during the season;\n(6)the seasonal energy efficiency ratio SEER shall be calculated as the ratio of the reference annual cooling demand QC and the reference annual energy consumption for cooling QCE ;\n(7)the seasonal space cooling energy efficiency ηs,c shall be calculated as the seasonal energy efficiency ratio SEER divided by the conversion coefficient CC, corrected by contributions accounting for temperature control and, for water/brine-to water comfort chillers, or water/brine-to-air air conditioners only, the electricity consumption of ground water pump(s);\n(d)For multi-split air-to-air air conditioners the measurement and calculations shall be based on the performance of the outdoor unit, with a combination of indoor unit(s) recommended by the manufacturer or importer.",
