With “mildly flammable” refrigerants playing an increasing role, UK industry body FETA has published a guidance note on the subject and is to set up a new A2L refrigerants working group.

The Gambia Technical Training Institute (GTTI) has just provided its first training workshop for entrepreneurs and technicians on refrigeration and air conditioning using natural refrigerants.

Stefan Jensen, managing director of low-charge ammonia system manufacturer Scantec, told ATMO Australia 2017 about his hopes for more compact ammonia systems that can work in air conditioning, supermarkets and commercial refrigeration.

The German government’s Federal Motor Transport Authority has called on Daimler to recall cars filled with refrigerant R134a in contravention of the MAC directive.

Daikin, the pioneer of the switch to lower GWP refrigerant R32 in air conditioners, claims to have sold a landmark 10 million units in 52 countries since its introduction.

Chinese air conditioning manufacturer Midea is to use R452B, a lower GWP alternative to R410A, in its unitary air conditioning units designed for the North American market.

At an international workshop on R290 air-conditioning this month, the Chinese Household Electrical Appliances Association and the Chinese Ministry of Environmental Protection (MEP/FECO) outlined their experiences with propane to an audience from across China, the Middle East and Vietnam.

The coalition wrote to the government early this week in advance of a UK climate plan.

A search of more than 60 million chemicals to find a replacement for R410A in air conditioning systems has found just 27 suitably-efficient fluids – but all are at least slightly flammable.

Several manufacturers at German trade show ISH displayed efficient systems using the natural refrigerant propane (R290).

Climaveneta heat pump chillers using low GWP, HFO refrigerant R1234ze are to reclaim waste heat from a data centre for one of Finland’s largest district heating networks.

A new paper released today by EPEE and ventilation group EVIA attempts to predict the HVAC and refrigeration needs of future generations.
