ASHRAE Standard 145.2-2016, developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), specifies a method of test for assessing the performance of gas-phase air-cleaning systems in removing gaseous contaminants from the airstream in commercial, industrial, and residential HVAC systems. This standard is complementary to ASHRAE Standard 145.1, which focuses on laboratory testing methods.
Key Aspects of ASHRAE Standard 145.2-2016
Objective
- To provide a standardized method for evaluating the in-situ performance of gas-phase air-cleaning devices installed in HVAC systems.
Scope
- The standard applies to the testing of air-cleaning systems designed to remove gaseous contaminants, such as volatile organic compounds (VOCs), from indoor air.
- It focuses on performance in real-world conditions as opposed to the controlled laboratory settings described in ASHRAE Standard 145.1.
Testing Procedures
- Details procedures for setting up and conducting field tests to measure the removal efficiency and capacity of gas-phase air-cleaning devices.
- Includes guidelines for selecting test sites, introducing contaminants, sampling air before and after the air-cleaning system, and analyzing the data to determine performance metrics.
Performance Metrics
- Defines key metrics such as removal efficiency, which is the percentage reduction of contaminants, and breakthrough time, which is the time until the air cleaner's performance significantly declines.
- Emphasizes real-world effectiveness and longevity of air-cleaning systems in operational environments.
Applications
- Relevant for HVAC professionals, building owners, and facility managers to ensure their air-cleaning systems are effective in actual working conditions.
- Useful for manufacturers to validate and demonstrate the effectiveness of their products in removing harmful gaseous contaminants from indoor air.
Benefits of ASHRAE Standard 145.2-2016
- Real-World Relevance
- Provides a method to assess how well gas-phase air cleaners perform in actual operating conditions, offering a realistic measure of their effectiveness.
- Improved Indoor Air Quality
- Ensures that air-cleaning systems contribute effectively to maintaining healthy indoor air by removing gaseous pollutants.
- Consistency and Comparability
- Establishes a common framework for testing, enabling consistent and comparable results across different products and installations.
