Researchers at the Distance University of Madrid in Spain investigated the possibility of efficiently using the airflows generated by HVAC systems as a man-made wind resource. The team decided on a vertical wind turbine generator after examining the wind flow pattern because of its small size, light weight and nominal power of 9 kW, making it perfect for installation on HVAC systems. Results showed that the concept, tested at a data center in Colombia, can produce about 468 MWh per year from a single location. Read more

Located in the Puna of Jujuy in Argentina, the Cauchari plant has been equipped with more than 900 thousand solar panels that will occupy 600 hectares in the town of Susques, which is about 4200 m (13,780 ft) above sea level. Located in an area with one of the highest solar radiations on the planet, the Cauchari solar plant will not only power more than 100,000 homes, but also has the potential to generate no less than $25 million a year in income for the province of Jujuy.

Several advocacy groups have joined former Texas prison inmates in filing a complaint in the U.S. District Court in Austin against the Texas Department of Criminal Justice's (TDCJ), asking that the TDCJ to provide adequate air conditioning in its state prisons where temperatures often reach scorching levels during the summer. Last year, uncontrolled heat led to several deaths and hundreds of cases of serious heat-related illnesses in these facilities, and advocacy groups are claiming that the TDCJ’s current heat-mitigation policy is unconstitutional. A preliminary injunction requested the courts to lower temperatures inside state prisons while a larger lawsuit is settled, but the TDCJ has not taken any action. Read more

Surgical patients release waste anesthetic gases that can cause potential health effects for people who care for patients in the post-anesthesia care unit. Kishor Khankari, Ph.D., Fellow ASHRAE, discusses optimizing its ventilation design to effectively remove these gases and reduce exposure. This technical feature appears in the October 2024 issue of ASHRAE Journal.

ASME Considering Scope Change to Boiler and Pressure Vessel Code
The American Society of Mechanical Engineers (ASME) is considering a scope change to its Boiler and Pressure Vessel Code (BPVC) Section VIII, Rules for Construction of Pressure Vessels, Division I that would eliminate long-standing exemptions for certain equipment manufactured by the Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI) member companies. According to AHRI, the change, if implemented, removes key exemptions that the HVAC&R and water heating industry has successfully covered with its own codes and standards for decades. It would alter the way relevant standards and codes interact with, and are interpreted by, jurisdictions. Removing ASME’s BPVC scope exemptions would place the BPVC in conflict with many codes and standards that currently occupy this space, such as those from nationally recognized testing laboratories (e.g., UL), standards development organizations SDOs (e.g., ASHRAE) and even other ASME codes.
