Key standards & Regulations for HVAC/r Products using low GWP refrigerants

 
 
UL 60335-2-40 describes the requirements for electrical heat pumps, air conditioners and dehumidifiers, and is an ANSI/SSC-accredited U.S./Canada binational consensus safety standard. It is based on IEC 60335-2-40, the international standard that currently serves as the basis for evaluating, testing and certifying HVAC equipment designs using low GWP refrigerants in Europe and elsewhere.
 
 
UL Solutions recently transitioned to the new harmonized standard UL 60335-2-89, which covers UL 412, the Standard for Refrigeration Unit Coolers; UL 427, the Standard for Refrigerating Units; UL 563, the Standard for Ice Makers; and UL 471, the Standard for Commercial Refrigerators and Freezers. UL 60335-2-89 is harmonized with the IEC and covers all current market changes, easing global market access and simplifying testing for manufacturers.
 
 
To capture all current market changes, ease global access and simplify testing, UL Solutions is also transitioning their traditional Standards - including UL 1995, the Standard for Heating and Cooling Equipment, and UL 484, the Standard for Room Air Conditioners - to align with harmonized International Electrotechnical Commission (IEC) standards.
 
In this continuously changing scenario, it's important to highlight the key standards and regulations to consider for evaluating HVAC/R products using low GWP or flammable refrigerants.

UL Standards & Engagement (UL Solutions) Unveils New Boiler Certification

In February 2024, UL Standards & Engagement (UL Solutions) published the ninth edition of UL 795, the Standard for Commercial-Industrial Gas-Fired Package Boilers. This is now a bi-national Standard, ANSI/CAN/UL 795:2024 Standard for Commercial-Industrial Gas-Fired Package Boilers. It is the first North American Standard that offers manufacturers a path to certification for boilers using hydrogen blending up to 25%, setting a new benchmark for the industry. The scope of UL 795 UL 795 prov...

Understanding UL 60335-2-40 Standard For Safer HVAC/R Systems

To address growing concerns about climate change and environmental sustainability, regulatory bodies, consumers and other stakeholders have placed an increased focus on the reduction of potent greenhouse gas emissions, such as traditional hydrofluorocarbon (HFC) refrigerants, to the atmosphere. In the U.S., several states have introduced measures curtailing the use of these products, including the California Air Resources Board’s (CARB’s) global warming potential (GWP) limit of 750,...

Embracing The Future Of HVAC: Technology Shifts, Codes And Standards

Heat pumps are not new technology. They have long been utilized in residential applications to improve the efficiency of HVAC systems, reducing overall energy costs. As a simple description, a heat pump is a mechanical refrigeration system that is engineered to operate in reverse mode, producing heating instead of cooling. technology drivers In recent years, there has been a trend of new and increased applications for this technology coming from two primary drivers: Advances in technolog...
