Foreword
This document (prEN 14037-5:2011) 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 document is currently submitted to the CEN Enquiry.

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 describes the test method and the test installation for determining the thermal output of
ceiling mounted heating surfaces according to the specifications of prEN 14037-1, clause 3.3.2, 3.3.3 and 3.3.4.

This part applies to determine thermal output when chilled ceilings according to EN 14240 are also used for heat-
ing.
NOTE Test results according to this part can not be compared with results according prEN 14037-2 because great dis-
crepancies are given at open ceilings, convective components and heating surfaces without upper insulation.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in prEN 14037-1 apply.
4 Testing of thermal output
The test is carried out in a testing system, which consists of a closed booth with controlled temperatures of the in-
side surfaces plus a set of two master panels built according to prEN 14037-2, Clause 6.
Differing from the definitions of the test booth according to prEN 14037-2, the ceiling and the upper part of the ver-
tical walls of the test booth shall be insulated until 0,5 m (± 0,02 m) below the ceiling with a thermal resistance of ≥
-2
K)/W.
2,5 (m
The method for measuring the thermal output consists of the measurement of mass flow and enthalpy difference
between inlet and outlet (by weighing method). Other measurement methods shall guarantee in minimum the pre-
cision obtained by weighing method. The natural convection within the test booth must not be affected by additional
means.
All laboratories that make tests according to this standard have to make comparable measurements with the other
laboratories (according to prEN 14037-2, Clause 6).

5 Test methods
The test method shall be carried out according to prEN 14037-2, Clause 7.
6 Carrying out the measurement
6.1 General
The natural convection inside the test booth shall not be influenced by additional means.
6.2 Test design
The test sample shall be installed in the test cabin according to the instructions of the manufacturer. The arrange-
ment of the sample shall be symmetrical if possible otherwise as much regular as possible. In case of closed ceil-
ings (see prEN 14037-1, 3.3.2 and 3.3.4) filling panels have to be installed when the projected surface is smaller
than the test booth. The filling parts shall be thermally insulated according to clause 4.
The total standard heat output of the installed sample shall be minimum 400 W and the active surface shall cover at
least 15 % of the total ceiling of the test booth (approx. 2.2 m²).
The active area ratio shall be calculated with:
A

R =    (1)

R the active area ratio;

and connected to the heating system, overlapping surfaces will be single evaluated.
A the installation surface.
i
At closed ceiling surfaces the active area ratio shall be declared together with the standard output value.
The distance from the lower surface of the test item to the insulated ceiling of the test booth h (void behind the
v
item including the height of the test item) shall not exceed 300 mm.
6.3 Connection of the test sample to the measuring circuit
After installation and connection to the measuring circuit, the test sample and the water circuit shall be carefully
vented. During the test, the measuring circuit shall be free of air inclusions.
The procedure of venting is to be described in the working instructions of the test laboratory.
If the water-attracting pipes are not an element of the standard installation, but are intended for the test, they shall
be provided with a maximum thermal conductivity of 4 W/m² ⋅ K.
6.4 Mass flow
The water flow rate shall be regulated so that the result of the difference between inlet and outlet temperature shall
be 4 K ± 0,2K at a temperature difference of 20K ± 2K. During the test for measuring the three points of th
