Interpretation of the requirements in EN When using the calorimeter room method, pressure equilibrium between indoor and outdoor compartments shall be obtained by introducing into indoor compartment, air at the same rating temperature conditions. The faster, easier way to work with standards. 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 standard does not include test on electrical safety, mechanical safety, control equipment and sound power level.
SP is accredited to perform field measurement tests in accordance with SP Method which is a method for measurement of the capacity and electricity consumption of air-to-air heat pumps in the field. 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 also includes verification of product marking on the heat pump.
The testing includes capacity testing, sound power level measurements and to a certain extent safety control tests. For more information regarding P-marking of heat pumps, click here.
The standard refers to field testing of heat pumps in field. The method is used for sound power level determination.

Energy performance of buildings – Method for calculation of system energy requirements and system efficiencies – Part 3: Testing and requirements for marking Withdrawn. This standard specifies a ej for determination of sound power level for heat pumps.
Energy performance of buildings. This standard is used when testing the performance of large heat pumps. Table 11 for water-to-water, brine-to-water, water-to-brine and brine-to-brine units in cooling mode; Tables 12 to 15 for air-to-water in heating mode, depending on the temperature applications; Table 16 for air-to-water and air-to-brine units in cooling mode; Table 17 for liquid chilling packages with remote condenser; Table 18 for liquid chilling packages for heat recovery condenser; Table 19 for air-cooled multisplit systems and modular air-cooled multisplit systems in the heating mode; Table 20 for air-cooled multisplit systems and modular air-cooled multisplit systems in the cooling mode; Table 21 for modular heat recovery air-cooled multisplit systems; Table 22 for water-cooled multisplit systems and modular water-cooled multisplit systems in the heating mode; Table 23 for water-cooled multisplit systems and modular water-cooled multisplit systems in the cooling mode.
The method specifies the testing procedure, depending on whether the heat pump has constant capacity, variable capacity or incremental capacity control.
The data used in the calculations are based on results from a number of test points derived from EN The heating demand as calculated in the program varies in accordance with a duration diagram for the particular house.
SP is accredited to perform tests in accordance with SP Method that the method of performance-testing of electrically driven exhaust air heat pumps, determining their thermal power capacity, hot water production capacity and ventilation performance.

SS-EN Domestic hot water production. Testing includes performance, security, sound level and electrical characteristics, together with inspection of technical data, maintenance and installation instructions. Guidelines for inspection of ventilation and air-conditioning systems Modules M, M, M, M SP Method is a method used to calculate the seasonal performance factor of a system and the annual energy savings of water-to-water heat pumps and brine-to-water heat pumps.
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. How the noise is perceived depends not only on its level, but also on its characteristics. The requirements for the uncertainties of measurement of 4.
Take the smart route to manage medical device compliance. 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. This test method is used to test heating or cooling mode operation under part-load conditions. This pressure equilibrium can be achieved by using an equalising device or by creating an open space area in the separation partition wall, which dimensions shall be calculated for the maximum airflow of the unit to be tested.
SP Method is a method under ej used to calculate the seasonal performance factor of a system and the annual energy savings of air-to-air heat pumps. 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.
