23、d by Technical Committee CEN/TC 113 “Heat pumps and air conditioning units”, the secretariat of which is held by AENOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2011, and conflicting

24、 national standards shall be withdrawn at the latest by August 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the

25、CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

DIN EN 15879-1:2011-05 EN 15879-1:2011 (E) 5 1 Scope This European Standard specifies the terms and definitions, test conditions, test procedures and r

27、equirements for the rating and performance of direct exchange-to-water ground coupled heat pumps with electrically driven compressors, used for space heating and/or cooling. Brine can be used instead of water. This European Standard applies to factory-made units with horizontal in-ground collectors.

28、 In the case of units consisting of several parts, this standard applies only to those designed and supplied as a complete package. Water-to-direct exchange and direct-exchange-to-direct exchange ground coupled heat pumps are covered by EN 15879-2. Direct exchange-to-air ground coupled heat pumps an

29、d air-to-direct exchange heat pumps are covered by EN 15879-3. This European Standard does not apply to units using transcritical cycles, e.g. with CO2as refrigerant. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
