Currently the P-marking rules are being revised to bring them into line with new European requirements and standard EN The loudness of the noise depends on the size of the room in which the heat pump is installed, its shape and its attenuation echo.
The performance rating shall be established in accordance with the test procedure of EN SP is accredited to perform tests in accordance with standard ENwhich contains calculation methods for determination of seasonal energy efficiency and seasonal coefficient of performance.
NOTE 1 For air-to-water, brine-to-water and water-to-water units, the manufacturer may declare the water temperatures levels lower, medium, high and very high applicable to the heating mode.

SP Method is a method under progress used to calculate the seasonal performance factor of a system and the annual energy savings of air-to-water heat pumps. Test conditions This document has been re-assessed by the committee, and judged to still be up to date. The method is based on the calculation method in standard EN The standard also describes testing with reduced capacity in heating operation mode or cooling operation mode.
Standard rating conditions indicated in Table 20 shall be used to determine the cooling capacity, the EER, the annual energy consumption and the efficiency class of air-cooled multisplit air conditioners.
