Beaulier Date of publication: SP Method calculation of annual energy savings. The test is performed at the flow rate obtained during the test at the corresponding standard rating conditions. 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-air heat pumps.

Standards and methods used by SP for testing of heat pumps

For undated references, the latest edition of the referenced document including any amendments applies. Guidelines for inspection of ventilation and air-conditioning systems Modules M, M, M, M Air leakage, thermal insulation and standby power requirement are also tested.

The performance test is carried out in accordance with EN at a number of defined test points specified in EN For reverse cycle units, the heating capacity and the efficiency class shall be determined from one of the standard rating conditions indicated in Table 3 depending of the heat source and heat sink. The test involves two draw offs of half the volume of the storage tank, together with a single tapping to determine the maximum quantity of useable hot water and the reference hot water temperature.

ISO Sound power level measuremnts. A function test includes measurement of the operating temperature range, correct operation after a power failure, and correct operation of safety devices in the event of pressure loss in the refrigerant or during failure of heat transfer medium flow.

Measurement of fractional efficiency and air flow resistance ISO Air filters for general ventilation – Part 2: When using the calorimeter room method, pressure equilibrium between indoor and outdoor 145111-2 shall be obtained by introducing into indoor compartment, air at the same rating temperature conditions.
