UL Solutions news
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...
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,...
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...
