SP Method updated version. Customers who bought this product also bought BS EN The test also includes verification of product marking on the heat pump.
Air leakage, thermal insulation and standby power requirement are also tested. Also gives the conditions for which performance data shall be declared for single duct and double duct units. The testing includes capacity testing, sound power level measurements and to a certain extent safety control tests.
Follow these links to find other Standards similar to the one you are viewing. NF-mark is valid for air-to-air- air-to-water- brine-to-water- water-to-water- exhaust air- and direct expansion heat pumps.
Beaulier Date of publication: 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 and some additional test points. At the minimum flow rate specified by the manufacturer. The requirements for the uncertainties of measurement of 4.
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. November Number of pages: Energy Savings Calculation SP Method is currently used for air-to-air heat pumps, air-to-water heat pumps and liquid-to-water heat pumps.
SP Method calculation of annual energy savings. SS-EN Domestic hot water production. Once determined, the static pressure shall be set, with dry coil, by adjusting to the air discharge area of the unit, a length of duct equipped with fn damper which position shall not be changed during the capacity tests.

Standards and methods used by SP for testing of heat pumps
The energy savings calculated is a comparison between a house having e electric heating and the same house having an air-to-water heat pump installed. For all units, electrical power voltage and frequency shall be 145112 by the manufacturer. This test method is used to test heating or cooling mode operation under part-load conditions. Terms and Conditions Terms of subscription Online watch. Attention is 14511-2 to the possibility that some of the elements of this document may be the subject of patent rights.
Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling – Part 2: The sound power level is a measure of the contribution of noise to the surroundings caused by the heat pump. The method is used to measure the airborne noise to the surroundings from heat pumps, air conditioners, liquid chillers and dehumidifiers when in operation.
Discover also Certification, assessment, diagnosis Get a quote for certification of systems, products or services, and get certified. The pressure difference between the two compartments of the calorimeter room shall not be greater than 1,25 Pa. 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.
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 and some additional test 15411-2.
The houses are postulated as located in areas with average annual temperatures of 8. How the noise is perceived depends not only on its level, but also on its characteristics.
The P-mark on a heat pump indicates that the heat pump fulfills the requirements set out in certification rules SPCR Take the smart route to manage medical device compliance. SP is a method used to calculate the seasonal performance factor of a system and the annual energy savings, in comparison with a house having direct electric heating.

Want access to British Standards? NOTE 2 For comparison purposes between reverse cycle and non reverse cycle units, the conditions on the water side are given by the inlet and outlet water temperatures, possibly leading to different water flow rates in heating and cooling modes.
The length of duct and the distance of the damper from the discharge section of the unit shall conform to the requirements of EN The heating coil of the heat pump is assembled in a brine bath held at constant temperature during the test. SP is accredited to perform tests in accordance with standard EN More information add to basket. The standard does not include test on electrical safety, mechanical safety, control equipment and sound power level.
Test yourself or your business online. It is also applicable for delivery testing of heat pumps at the factory or equivalent. The time and energy requirements for heating up, energy use, standby power losses and overall efficiency of the equipment are measured and evaluated.
