ANSI/ASHRAE 15-2019 7.2.2(c) Standard 15 details that an alarm must have visible and audible cues to alert operators of a leak. %PDF-1.5 <> It prohibited venting, required technician certification, provided for safe disposal, mandated accurate record keeping, and required corrective actions for leak rates greater than 35 percent. It governs the safe handling of refrigerants for commercial and industrial applications. There are several refrigerant leak-detection technologies available, but they fall into two primary categories: direct and indirect. The air conditioning and refrigeration industry has been actively working to address this issue since 2006 by developing a new classification of refrigerants, known as A2L, to meet the lower GWP challenge. Refrigerant users and system operators will want to check local and state regulations to follow the appropriate guidelines. It may be beneficial to perform a side-by-side comparison of installation, maintenance, and other lifecycle costs to determine which leak detection system would be the most cost-effective for a given installation. A binational (U.S. and Canada) consensus group was formed to update the product safety and application standards to allow for the safe use of these more environmental friendly refrigerants within HVAC systems. There are several codes that could apply, depending on where the facility is located: In cases where an industrial process shutdown is required, a repair period of 120 days is substituted for the normal 30-day repair period.
