Division 2 For establishing the values of cooling capacity, power input, coefficient of performance and seasonal energy performance ratio, measurements shall be made under the following conditions:
United Kingdom
- (a)
the reference ambient temperature at the outdoor heat exchanger (condenser) shall be 32 °C;
- (b)
the saturated evaporating temperature at the indoor heat exchanger (evaporator) shall be – 35 °C for low temperature and – 10 °C for medium temperature;
- (c)
where applicable, the variations of ambient temperature throughout the year, representative of average climate conditions in the Union, and the corresponding number of hours when these temperatures occur, shall be as set out in Table 6;
- (d)
where applicable, the effect of the degradation of energy efficiency caused by cycling, depending on the type of capacity control of the condensing unit, shall be taken into account.
