Membership has its priviledges.

In response to growing legislative pressure to use refrigerants with lower GWPs, Johnson Controls has made the decision to enhance its HFC product lines by confirming that all screw and centrifugal chillers (air-cooled and water-cooled) will be fully future-compatible with R315A. This refrigerant is an HFC/HFO blend and has a GWP of 631. It is suitable as a drop-in replacement for R134a, which has a GWP of 1430. It has a low toxicity and is not flammable.

Discreet comfort

02 June, 2016

Refurbishment projects often require effective control of comfort conditions within strict aesthetic constraints. Rinus Groenewald of Unico explains why small-duct high-velocity air-conditioning systems can offer a discreet alternative to other solutions.

Trane’s Sentesis eXcellent range of air-cooled chillers use HFO R1234ze as the refrigerant, which has a GWP of less than one when used in this design. These chillers offer capacities from 500 to 1260 kW. Applications include data centres, hospitals, and large office buildings.

AET, underfloor air conditioning, air conditioning

As part of the full structural reconfiguration and refurbishment of 33 Glasshouse Street in central London, AET Flexible Space is supplying underfloor air conditioning.

Since their introduction to the UK in the 1970s, fan-coil units (FCUs) have provided air conditioning to thousands of commercial buildings. However, there is another option to consider, which delivers energy efficiency and, importantly, flexibility — namely the chilled beam. Yan Evans of Fläkt Woods explains why it’s time to move on from the FCU.
