Free hanging heating and cooling surfaces for water with a temperature below 120°C - Part 5: Open or closed heated ceiling surfaces - Test method for thermal output

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 14037-1:2011, 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 heating.
NOTE   Test results according to this part cannot be compared with results according to EN 14037-2 because great discrepancies are given at open ceilings, convective components and heating surfaces without upper insulation.

Prosto viseče grelne in hladilne površine za vodo s temperaturo do 120 °C - 5. del: Odprte ali zaprte stropne grelne površine - Metoda preskušanja toplotne moči

Ta evropski standard opisuje preskusno metodo in preskusno napravo za določevanje toplotne moči stropnih grelnih površin v skladu s specifikacijami prEN 14037-1:2011, 3.3.2, 3.3.3 in 3.3.4.
Ta del se uporablja za določitev toplotne moči, kadar se ohlajeni stropi v skladu s standardom EN 14240 uporabljajo tudi za ogrevanje.
OPOMBA   Rezultatov preskusov, pridobljenih v skladu s tem delom, ni mogoče primerjati z rezultati, pridobljenimi v skladu s standardom EN 14037-2, ker so pri odprtih stropih, konvekcijskih sestavnih delih in grelnih površinah brez zgornje izolacije podane velike neskladnosti.

Overview

EN 14037-5:2016 is a European Standard developed by the European Committee for Standardization (CEN) focusing on free hanging heating and cooling surfaces for water with a temperature below 120°C. Specifically, Part 5 covers the test method for determining the thermal output of open or closed heated ceiling surfaces. The standard provides a unified test procedure and installation guidelines, making it essential for manufacturers, testing laboratories, and building professionals aiming for effective and comparable measurement of ceiling-mounted radiant panels used for both heating and cooling.

This standard is applicable to ceiling systems where water-based chilled ceilings, as defined in EN 14240, are also utilized for heating purposes. It defines specific conditions and terminology, ensuring consistency across the industry in thermal performance reporting.

Key Topics

• Test Methods
  Describes procedures for installing the test sample, maintaining reference room temperatures, measuring water flow, and calculating thermal output. The method is built around controlled test booths and steady-state conditions to ensure reliable data.

• Types of Ceiling Heating Surfaces
  Defines distinctions between open and closed ceiling surfaces, free hanging sail surfaces, and suspended ceilings with integrated heating elements. It covers active vs. non-active surfaces and how to calculate active area ratios.

• Measurement and Reporting
  Outlines the data to be provided in the formal test report, such as installation and active surfaces, upper insulation details, water and air temperature measurements, and the final calculation of standard thermal output.

• Limitations of Comparisons
  Clarifies that test results derived from this method cannot be directly compared with results from EN 14037-2 due to differences in setup-particularly for open ceilings, convective components, and surfaces without upper insulation.

Applications

• Product Development and Testing:
  Manufacturers use EN 14037-5 to validate the thermal performance of modular ceiling-mounted systems for space heating and cooling. The standard is critical during product certification, quality assurance, and R&D phases.

• Building Design and Energy Efficiency:
  Architects and HVAC engineers rely on the test methods defined in EN 14037-5 to specify and compare radiant ceiling systems in commercial, educational, and residential buildings. It ensures designers select products with verified and consistent heating/cooling outputs, supporting building energy efficiency goals.

• Laboratory Accreditation:
  Testing laboratories utilize the procedures detailed in EN 14037-5 and referenced standards (such as EN ISO/IEC 17025) to provide reliable, repeatable thermal output measurements required by regulators, clients, and product manufacturers.

• Regulatory Compliance:
  The standard helps to demonstrate conformity with building code requirements for central heating systems, particularly where modular ceiling radiant panels are installed.

Related Standards

• EN 14037-1: Pre-fabricated ceiling mounted radiant panels for space heating - Technical specifications and requirements
• EN 14037-2: Test method for thermal output (not directly comparable due to methodological differences)
• EN 14037-3: Rating method and evaluation of radiant thermal output
• EN 14037-4: Test method for cooling capacity
• EN 14240: Ventilation for buildings - Chilled ceilings - Testing and rating
• EN ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories

By adhering to EN 14037-5:2016, professionals involved in the design, testing, and certification of ceiling-mounted radiant heating and cooling systems can ensure high quality, safety, and energy efficiency across a wide range of building environments. The unified procedures promote trust, transparency, and product comparability within the European and international markets.
