Foreword
This document (prEN 14037-4:2011) has been prepared by Technical Committee CEN/TC 130 “Space heating

Introduction
This European Standard results from the recognition that the ceiling mounted heating and cooling surfaces falling
into the field of application hereinafter stated are traded of the basis of their thermal and cooling output. For evalu-
ating and comparing different ceiling mounted radiant panels it is therefore necessary to refer to a single stipulated
value.
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: Technical specifications and requirements
- Part 2: Test method for thermal output of ceiling mounted radiant panels
- Part 3: Rating method and evaluation of radiant thermal output of ceiling mounted radiant panels
- Part 4: Test method for cooling capacity of ceiling mounted radiant panels
- Part 5: Test method for thermal output of open or closed heated ceiling surfaces

1 Scope
This European Standard defines the technical specifications and requirements for the definition of the cooling ca-
pacity of ceiling mounted radiant panels according to the specifications of prEN 14037-1, clause 3.3.1. The test
according to this standard requires the measurement of the thermal output according to prEN 14037-2 of the
model.

4 Testing of cooling capacity
4.1 Short description
The cooling capacity of the test sample has to be determined in its steady condition with measurements of the wa-
ter flow and the temperature increase in the water. The cooling capacity shall be quoted as function of the tempera-
ture difference between the reference temperature and the average water temperature.
The test is carried out in a testing system according to prEN 14037-2, which consists of a closed booth with con-
trolled temperatures of the inside surfaces plus master panel 1 (according to prEN 14037-2, Clause 6). All laborato-
ries performing tests according to this standard shall participate in inter-laboratory comparison exercises (according
to prEN 14037-2, Clause 6).
For covering the cooling capacity, the test booth will be heated with a number of electrical heated cooling load
simulators which are positioned on the floor of the test booth. To get reproducible results, the simulators have to be
arranged according to 4.2.
4.2 Test booth
The test is carried out in a test booth according to prEN 14037-2, Clause 5.
Differing from these definitions the surfaces, floor and ceiling of the test booth shall be insulated in the way that the
average heat flow in those surfaces is lower than 0,40 W/m² during the test. This heat flow shall be determined by
preliminary calibration tests of the booth or by calculations.
Differing to prEN 14037-2, 5.4 the reference temperature during the measurement shall be 32 °C ± 0,5K in the
steady condition for minimum 30 minutes.

The temperature(s) of inner surfaces of walls, floor and ceiling of the test booth (under the insulation) shall be con-
trolled and be kept on a value, which is necessary to guarantee a max. temperature difference between these sur-
faces and the reference temperature of less than 1,0 K.
The radiant emissivity of the surface of the insulation has to be at least 0,9.
The test booth will be heated with 6 electrical heated cooling load simulators (see figures 1 and 2 ), which are posi-
tioned on the floor of the test booth.
The output of each simulator must not exceed 180 W and shall be continuously adjustable, e.g. with an adjustable
transformer or a thyristor. Each simulator shall have an identical heat output and the same number of bulbs.
The housing of the simulators consists of painted steel sheet. The emissivity of the inside and outside surface shall
be at least 0,9. The active power of the simulators shall be measured with a measuring instrumen
