In the September 3rd issue of The NEWS, we explore alternative refrigerants, advancements in refrigeration technology, and new commercial refrigeration products. We also discuss lawmakers signing the Strengthening Career and Technical Education for the 21st Century Act into law.
The bill, which lawmakers and stakeholders often refer to as Perkins V, was an update of the Perkins Career and Technical Education Act of 2006. Perkins V represents the authorization (but not actual appropriation) of funds to support a range of career education opportunities, including HVAC-related training, for six years, beginning in July 2019.
