NEW ISSUE OUT NOW | HPT Magazine Vol. 44, No. 1/2026

27 May 2026

The first issue of Heat Pumping Technologies Magazine for 2026 is now available. This edition focuses on “Flammable Refrigerants in Heat Pumps: Safety, Standards, and Best Practices” – a topic of growing urgency as the industry transitions toward low-GWP working fluids at scale.

The issue features a foreword by Senior Professor Björn Palm (KTH Royal Institute of Technology), a column on Korea’s heat pump policy landscape, and four technical articles covering:

  • R-290 leakage dynamics and implications for charge-limit standards (KTH)
  • Safe experimental characterisation of A3 refrigerants (Purdue University)
  • Chemical stability of HFO refrigerants with POE lubricants under high-temperature aging (KTH)
  • A large-scale industrial heat pump deployment at a waste-to-energy plant in Brescia, Italy, achieving 98% plant efficiency using R1234ze(E)

The national market spotlight turns to Switzerland, with a dedicated heat pump market report covering deployment trends and policy drivers.
