3 European foreword This document (EN 14037-4:2016) has been prepared by Technical Committee CEN/TC 130 “Space heating appliances without integral heat sources”, the secretariat of which is held by UNI. 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of an identical text or by endorsement, at the latest by March 2017, and conflicting national standards shall be withdrawn at the latest by March 2017. The European Standard EN 14037, Free hanging heating and cooling surfaces for water with a temperature below 120°C, consists of the following parts: — Part 1: Prefabricated ceiling mounted radiant panels for space heating - Technical specifications and re-quirements; — Part 2: Prefabricated ceiling mounted radiant panels for space heating - Test method for thermal output; — Part 3: Prefabricated ceiling mounted radiant panels for space heating - Rating method and evaluation of radiant thermal output; — Part 4: Prefabricated ceiling mounted radiant panels for space heating - Test method for cooling capacity; — Part 5: Open or closed heated ceiling surfaces - Test method for thermal output. 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 CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portu-gal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 14037-4:2017

4 Introduction This European Standard results from the recognition, that heated and chilled ceiling radiant panels falling into the field of application hereinafter stated are traded on the basis of their thermal output. For evaluating and comparing different heated and chilled ceiling surfaces it is therefore necessary to refer to a heating stipulated value. As installations with ceiling mounted radiant panels can also be used in practice for space cooling, it is nec-essary to have a test method for evaluating the cooling capacity. Installations with different free hanging heating and cooling surfaces need, for the use of space heating a test method for evaluating the heating out-put. The test method differs from the method for ceiling mounted radiant panels. SIST EN 14037-4:2017

5 1 Scope This European Standard defines the technical specifications and requirements for the definition of the cool-ing capacity of pre-fabricated ceiling mounted radiant panels according to the specifications of EN 14037-1:2016, 3.3.1. The test according to this standard requires the measurement of the thermal output according to EN 14037-2:2016 of the model. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indis-pensable for its application.

7 5 Testing of cooling capacity 5.1 Short description The cooling capacity of the test sample shall be determined in its steady condition with measurements of the water flow and the temperature increase in the water. The cooling capacity shall be quoted as function of the temperature difference between the reference temperature and the average water temperature. The test is carried out
