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.
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.

Active chilled beams are finding increasing use in office and commercial buildings. They use a variety of solutions for air diffusion, adjustability and efficiency. By combining these in a smart way and adding new thinking, the optimal chilled-beam design can be achieved. Professor Göran Hultmark of Lindab explains.
Facilities-management provider Cloudfm can offer a 10-year warranty on Mitsubishi Electric air-conditioning equipment managed on behalf of its clients.

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.
The EC (electronically commutated) motors in Advanced Air’s horizontal fan deck have a chip developed by Nailor, the company’s American parent, which gives a pressure-independent unit and makes the fan-coil self balancing so that no commissioning is required on the air side.
Climate Center claims to be the first distributor to stock the low-GWP refrigerant R32 in every branch — amounting to 45 branches nationwide. R32 is a single-component refrigerant with a GWP of 675, considerably lower than the 2088 for R410A. The investment coincides with Daikin and Toshiba launching R32 air-conditioning ranges.
Lindab’s Solus chilled-beam system has been chosen to deliver energy-efficient climate control for a landmark building in Sweden — the Round House in the Munksjöstaden district.
