The benefits of linear compressors
Three articles published recently in the IJR illustrate the strength of R&D work around linear compressors and highlight the benefits of these, especially in commercial and domestic...
Reducing the environmental impact of ultra-low temperature refrigeration systems
Ultra-low temperature (ULT) refrigeration systems often use very high-GWP HFCs. Yet, ULT systems are excluded from the scope of the regulations aimed at phasing-down HFCs. An IJR paper reviews the most promising...
Low GWP blends for domestic air conditioning
