Testing, inspection and certification of air-conditioning and ventilation systems

Manufacturers of air-conditioning and ventilation systems have to navigate through many challenges from product development to installation. These challenges include compliance with legal requirements as well as safety and environmental compatibility. In addition, successful market entry also requires clear communication of the performance data of air-conditioning and ventilation systems such as maximum sound level during operation, efficiency of the system and its components and the system’s hygienic design. 

Our experienced air-conditioning and ventilation experts can help you overcome these obstacles and provide you with optimum support during the design, improvement or market entry of your air-conditioning and ventilation products.

PERFORMANCE RATINGS OF AIR-CONDITIONING AND VENTILATION SYSTEMS

Before air-conditioning and ventilation systems can be launched into the domestic and commercial market, the manufacturers need to know how their products perform in practice. Our Center of Competence (CoC) has several test rigs to determine the performance ratings of your systems and components. We offer the following tests and measurements:

• Performance measurements (including domestic ventilation systems, fan coil units, heat-recovery systems, heat exchangers, residential ventilation units, air handling units (AHUs))
• Air flow rate (e.g. fans, products with integrated fans)
• Tests according to EU Ecodesign Directives 327/2011, 1253/2014 and 1254/2014
• Tests according to EUROVENT (certification body for products) e.g. fan coil units, residential ventilation units, AHUs, model boxes, run around coil systems, adiabatic cooling systems)
• Flow-resistance value or zeta value (e.g. air ducts or air-duct components, overflow openings, air inlets or outlets)
• Mechanical characteristics of model boxes
• Leak tests (e.g. air ducts, louvres and dampers)
• Provision of various climate chambers or dual climate chambers at temperature ranges from -40°C to +50°C.

Inspection of air-conditioning and ventilation systems

Our experienced team provide certainty that your air-conditioning and ventilation components or systems are compliance with the applicable regulations and standards right from the manufacturing phase and that your products are in conformity with all safety, energy-efficiency, hygienic and acoustic requirements. Our inspection services include:

• Hygiene inspections of ventilation and air-conditioning components, units and systems
• Testing of AHU selection software
• Testing of selection software (e.g. heat recovery systems, fans)
• Inspection of standardised airways for fans according to DIN EN ISO 5801
• Inspections related to the FGK-QM-01 standard
• Third-party inspection of ventilation units according to DIN 18017 and heat and smoke exhaust fans (third-party surveillance of production, product surveillance)
• Witness audits

Certification of air-conditioning and ventilation systems

Proper certification allows advantages and characteristics of your products to be communicated to the market in a clear and easy-to-understand manner. The compliance with the applicable regulations and standards as well as conformity with all safety, energy-efficiency, hygienic and acoustic requirements are traceable and clearly documented. We offer the following certification services:

• Certification of performance data (DIN EN 13053, DIN EN 1886, DIN EN 308)
• Certification of the tightness of air ducts and/or dampers (DIN EN 1751, DIN 1507, DIN EN 12237)
• Certification of selection software for fans, heat recovery systems, air-handling units
• Certification of test rigs for measurements on fans, heat exchangers, heat-recovery systems
• Certification of cleaning services according to FGK-QM-01
• Certification of hygiene-relevant characteristics of AHUs and their components (DIN 1946-4, VDI 6022-1, VDI 3803-1, ÖNORM H 6021, SWKI VA 105-01)
• Certification of non-metal air duct systems according to TÜV SÜD test standard “TAK 01-2013”
