Overview

SIST EN 16583:2022/oprA1:2024 is a European standard developed by CEN for hydronic room fan coil units (FCUs), specifically focusing on the determination of the sound power level. These units are factory-made single assemblies designed for cooling and/or heating indoor spaces using water-based systems without including the actual heating or cooling source. Applicable to both air free delivery and air ducted units, this standard covers units operating under a maximum external static pressure of 300 Pa due to duct resistance. The document defines standardized methods to assess the acoustic performance of fan coil units under controlled working conditions and typical installation setups. Notably, SIST EN 16583:2022/oprA1:2024 targets laboratory and controlled environment testing rather than production or field testing protocols.

Key Topics

• Scope and Application
  • Focuses on factory-made hydronic fan coil units used in heating and cooling systems
  • Applicable to both ducted and non-ducted air delivery configurations
  • Considers maximum external static pressure constraints (≤ 300 Pa)
• Sound Power Level Measurement
  • Standardized methods for determining acoustical performance
  • Defines unit operation conditions, including fan speed and external static pressure (ESP) adjustments based on atmospheric conditions
  • Establishes installation conditions for consistent and comparable testing results
• Modifications and Updates
  • Amendment clarifies ESP calculations relative to standard air conditions
  • Updates formula numbering for clarity and reference within the standard
• Terminology
  • The term "unit" refers specifically to the hydronic fan coil unit throughout the document
• Limitations
  • Does not specify test methods for production line or onsite field testing

Applications

SIST EN 16583:2022/oprA1:2024 is essential for manufacturers, testing laboratories, and certification bodies involved in the design, evaluation, and quality assurance of hydronic fan coil units. Its practical applications include:

• Acoustic Performance Testing
  Ensuring fan coil units meet sound emission requirements to optimize indoor comfort and comply with building regulations regarding noise levels.
• Product Development
  Guiding engineers in designing low-noise hydronic fan coil units by providing standardized measurement methods for sound power, enabling performance benchmarking.
• Quality Control
  Supporting consistent factory testing protocols to verify compliance with acoustic performance criteria during product certification.
• Building HVAC Design
  Helping HVAC consultants specify fan coil units that maintain acceptable noise standards in residential, commercial, and institutional buildings.

Related Standards

To complement SIST EN 16583:2022/oprA1:2024, professionals may consider the following standards for a broader understanding of fan coil unit performance and HVAC system requirements:

• EN 12102 - Measurement of noise emitted by HVAC equipment
• EN 13779 - Ventilation for non-residential buildings - Performance requirements for systems and components
• EN ISO 3744 - Determination of sound power levels of noise sources using sound pressure-engineering methods for an essentially free field over a reflecting plane
• EN 12831 - Heating systems in buildings - Method for calculation of the design heat load
• EN 1772 - Terminology for HVAC and room air conditioning

Adherence to SIST EN 16583:2022/oprA1:2024 ensures accurate, repeatable acoustical measurement of hydronic fan coil units, facilitating improved indoor environmental quality and compliance with European regulatory frameworks.
