It also specifies test conditions for heat recovery operation of multisplit systems. The standard 1451-12 to EN and is valid for the same types of heat pumps: Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. The standard relates primarily to electrically driven heat pumps, but where applicable it can also can be used for heat pumps with other drive 14511-2 and for refrigeration applications.

Select the first category of products searched and follow the instructions. Air conditioners; liquid chiller packs; air-to-air- water-to-air- brine-to-water- and water-to-water heat pumps can be tested in accordance with the requirements of this standard. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.

Test yourself or your business online. 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.

The heating coil of the heat pump is assembled in a brine bath held at constant temperature during the test.

For reverse cycle air-cooled multisplit units, the heating capacity and the efficiency class shall be determined from the standard rating conditions indicated in Table This European Standard shall 14511- given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Apriland conflicting national standards shall be withdrawn at the latest by April The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.

Although we endeavour to maintain an up-to-date catalogue, on occasion we may een have the latest version of a document, including where it has not yet been provided through an international feed. 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. 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 a damper which dn shall not be changed during the capacity tests.

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. We recommend that you check the website of the publishers of the international document before making a purchase. Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling – Part 2: Terms and definitions EN The method is used to measure the airborne noise to the surroundings from heat pumps, air conditioners, liquid chillers and dehumidifiers when in operation.

The data used in the calculations are based enn 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.

A 14511- test includes measurement of the dn 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. Want access to British Standards? The testing includes capacity testing, sound power level measurements and to a certain extent safety control tests.
