10 things technicians should know about next generation refrigerants

Refrigerants are exponentially improving as the demands for eco friendliness and energy efficiency increase. New, alternative refrigeration gasses have become mainstream – dominating the HVAC&R market. HFCs are becoming a thing of the past and with expanding research and growth of HFOs (Hydrofluro-Olefins), HCs (Hydrocarbons) and CO2. Training of HVAC&R technicians is essential. Here are...

HVACR in 2017

Joe Sanchez, engineering manager, Bitzer US Inc., said three major trends are occurring in the HVAC arena: a desire for low-GWP (global warming potential) solutions, a call for higher energy efficiency, and a desire for ease of use. Compressors are a part of all three. “Low-GWP refrigerants are an industry-wide trend now, driven by worldwide... Continue Reading →


Compressor specialist BITZER has optimised its two-stage reciprocating compressors. All models can now be run with R448A and R449A refrigerants and thermostatic expansion valves. With low global warming potential (GWP) values of 1 386 and 1 397, both refrigerants are eco-friendly alternatives to R404A, whose GWP value is 3 922. The EU F-gas Regulation prohibits...
