AHRI 870 Testing for Thermal Characteristics of Service Coils: Eurolabs Laboratory Testing Services

Standard-Related Information

The thermal characteristics of service coils are critical in ensuring the efficient operation of heating, ventilation, and air conditioning (HVAC) systems. The Air-Conditioning, Heating, Refrigeration Institute (AHRI) has developed Standard 870, which provides guidelines for testing the thermal characteristics of service coils. This standard is widely accepted globally and is essential for manufacturers, designers, and installers of HVAC systems.

The AHRI 870 standard is based on international standards such as ISO 5167-1:2006 (Measurement of fluid flow in pipelines - Using orifice plates, nozzles, and venturi tubes), ISO 5168:2017 (Measurement of fluid flow in closed conduits - Principles and reference method for the determination of the pressure drop-pressure loss relationship), and ASHRAE Standard 51-1997 (Methods of Testing Fixed Air Cleaners to Determine Static Pressure-Flow Relationship).

Standard Requirements and Needs

The thermal characteristics of service coils are crucial in determining their performance, efficiency, and reliability. The AHRI 870 standard requires testing the following parameters:

  • Thermal capacity

  • Coil-to-coil pressure drop

  • Fan power consumption

  • Airflow rate

    • Conducting AHRI 870 testing is essential to ensure that service coils meet the required standards for thermal characteristics. Failure to comply with these standards can lead to reduced system performance, increased energy consumption, and decreased lifespan.

    Industries and Sectors

    The following industries and sectors require AHRI 870 testing:

  • HVAC manufacturers

  • System designers and installers

  • Building owners and operators

  • Regulatory agencies

    • These stakeholders rely on accurate and reliable testing results to ensure that service coils meet the required standards for thermal characteristics. Failure to comply with these standards can lead to reduced system performance, increased energy consumption, and decreased lifespan.

    Test Conditions and Methodology

    The AHRI 870 standard specifies the following test conditions:

  • Test temperature: 20C 5C

  • Relative humidity: 40 10

  • Pressure drop: 100 Pa 50 Pa

    • The testing methodology involves the following steps:

    1. Pre-testing preparation

    2. Coil installation and testing setup

    3. Thermal capacity testing

    4. Coil-to-coil pressure drop testing

    5. Fan power consumption testing

    6. Airflow rate testing

    Test Reporting and Documentation

    The test results are documented in a comprehensive report that includes the following information:

  • Test conditions and methodology

  • Test results for thermal capacity, coil-to-coil pressure drop, fan power consumption, and airflow rate

  • Interpretation of test results

  • Recommendations for improvement

    • The report is structured according to international standards such as ISO 9001:2015 (Quality management systems - Requirements) and ISO/IEC 17025:2005 (General requirements for the competence of testing and calibration laboratories).
