Comprehensive Guide to EN 50598-2 Energy Efficiency of HVAC Speed-Controlled Drives Laboratory Testing Service

EN 50598-2 is a European Standard that specifies the requirements for energy efficiency testing of speed-controlled drives used in heating, ventilation, and air conditioning (HVAC) systems. The standard is part of the CENELEC series of standards on energy efficiency and is widely adopted across Europe.

The standard is developed by CEN/CLC/JTC 11, a technical committee responsible for developing European Standards related to electrical installations and equipment. EN 50598-2 is based on ISO/IEC 60825 (Electrical safety in the workplace) and IEC 61000-3-2 (Electromagnetic compatibility - Part 3-2: Limits for harmonic current emissions).

The standard specifies two test methods:

1. The first method involves measuring the energy efficiency of the speed-controlled drive under steady-state conditions.

2. The second method involves simulating real-world operating conditions, including variations in load and ambient temperature.

Legal and Regulatory Framework

EN 50598-2 is widely recognized as a benchmark for energy efficiency testing of HVAC speed-controlled drives across Europe. Compliance with this standard is mandatory for manufacturers selling products in the European market. National governments have implemented regulations to ensure that products comply with EN 50598-2, such as:

  • EU Directive 2009/125/EC: Establishes minimum requirements for product labeling and energy efficiency.

  • EU Regulation 811/2010: Specifies labeling requirements for HVAC equipment.

    • International Standards

    EN 50598-2 is harmonized with international standards developed by the International Electrotechnical Commission (IEC). IEC 60825 and IEC 61000-3-2 are widely adopted globally. Manufacturers selling products in other regions, such as North America or Asia-Pacific, must comply with local regulations and standards.

    Standard Development Organizations

    Standards development organizations (SDOs) play a crucial role in developing and maintaining EN 50598-2. CEN/CLC/JTC 11 is responsible for updating the standard to reflect changes in technology, regulatory requirements, and industry needs.

    Evolution of Standards

    Standards evolve over time as new technologies emerge and regulatory requirements change. Eurolab stays up-to-date with the latest developments and updates its testing protocols accordingly.

    Standard Numbers and Scope

    EN 50598-2 is part of a larger series of standards on energy efficiency, including:

  • EN 50596: Energy efficiency of variable speed drives

  • EN 50755: Energy efficiency of power supplies

    • These standards ensure that products meet minimum requirements for energy efficiency and safety.

    Standard Compliance Requirements
