BS EN 98 Vicker The energy savings calculated 15411-2 a comparison between a house having direct electric heating and the same house having a water-to-water heat pump or a brine-to-water heat pump installed. The marking also includes heat pumps intended for pool heating. SP Method is a method under progress used to calculate the seasonal performance factor of a system and 41511-2 annual energy savings of air-to-water heat pumps.

The faster, easier way to work with standards. If you need help with the purchase or have any queries please email enquiries standards. It also specifies test conditions for heat recovery operation of multisplit systems.

The data used in the calculations are based on results from a number of test points derived from capacity and efficiency testing in accordance with ENEN and EN 41511-2 some additional test point. Search all products by. The method is used for sound power level determination. Energy performance of buildings.

SP Method is a method under progress used to calculate the seasonal performance factor 14511- a system eb the annual energy savings of air-to-air heat pumps. It can be used for heat pumps in both heating and cooling operating modes. 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.

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.

The sound power level is a measure of the contribution of noise to the surroundings caused by the heat pump. NOTE 1 For air-to-water, brine-to-water and water-to-water units, the manufacturer may declare the water temperatures levels lower, 144511-2, high and very high applicable to the heating mode.

The energy savings calculated is a comparison between a house having direct electric heating and the same house having an exhaust air heat pump installed. Performance-based maintenance of air-handling systems ducts and eh You may be interested in this related standard.
