For reverse cycle units, the heating capacity and the efficiency class shall be determined from the standard rating conditions indicated in Table The test measures performance over a period of one day, with a number of hot water draw-off periods.
For 14511- with brine, the test shall be carried out with the brine specified by the manufacturer, see 7.
NBN EN 14511-2
1411-2 SP is accredited for the method and performs tests in accordance with EN as required by customers. Chapter 1 and 2 Test Interpretation of the requirements in EN Also gives the conditions for which performance data shall be declared for single duct and double duct units. Testing includes performance, security, sound level and electrical characteristics, together with inspection of technical data, maintenance and installation instructions.
Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling – Part 2: The method applies for electrically driven heat pumps.
The maximum quantity of useable hot water and the reference hot enn temperature are measured during a single draw-off. The test also includes verification of product marking on the heat pump.
The method is used to measure the airborne noise to the surroundings from 145111-2 pumps, air conditioners, liquid chillers and dehumidifiers when in operation.
Again there may be more recent versions of the document. The energy savings calculated is a comparison between a house having direct electric heating and the same house having an air-to-water heat pump installed.
Terms and Conditions Terms of subscription Online watch. 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. Option to visualize changes at a glance. The method includes testing of safety functions and inspection of technical data, maintenance and installation instructions.
More information add to basket. Test conditions No longer current but cited in Building Regulations guidance. A complete test in accordance with this standard tests and measures the performance of the heat pump, derives technical data, and inspects maintenance and installation instructions. 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 EN and EN and some additional test points.

Air conditioners, liquid chilling packages and heat pumps for space heating and cooling and process chillers, with electrically driven compressors – Part 2: The standard relates primarily to electrically driven heat pumps, but where applicable it can also can be used for heat pumps with other drive motors and for refrigeration applications. Air filters for general ventilation – Part 2: The heat pump is tested and marked for the temperature condition it is intended to work at.
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. Select the first category of products searched and follow the instructions. Terms and definitions, Part 2: For dated references, only the edition cited applies. The heating demand of the house varies with the outdoor temperature; this is represented by temperature bins amount of hours at each degree Celsius.
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. 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.
Sound power level measurements are performed at specified positions around the sound source and around a reference sound source, from which the sound power level can be calculated.
