Cool-Therm Ltd reports a surge in interest in alternative refrigerant-based chillers, as clients put the focus on GWP and natural cooling solutions.
The company says it has recently received an order for one of the latest generation of HFO-based chillers for a new university facility, and two orders for hydrocarbon-based systems for a convenience store and a council building.
According to Cool-Therm, the HFO chiller has been specified for a new research centre in Nottingham. The refrigerant HFO1234ze was chosen due to its very low global warming potential (around 5-6), which attracts additional BREEAM and LEED credits.
The 60kW ducted VHR chiller, manufactured by Italian company Geoclima, will be equipped with refrigerant leak detection and an automatic pump down system, to isolate the plant from the building in the event of a leak.
Given the educational setting, noise emissions were also an important design consideration. Acoustic control is being used on both the intake and discharge sides of the plant with special air intake louvres, designed and installed by the contractor on the project, Nottingham-based Imtech G&H Ltd.
Cool-Therm has also supplied natural cooling solutions in the form of reciprocating compressor-based propane (R290) chillers. The first is for a Co-op convenience store at Alsager, Staffordshire, providing comfort cooling for the store environment. Noise was also an issue at the site, and acoustic attenuation was fitted around the compressor to ensure the specification was met.
The second propane chiller was for a South Staffordshire Council building, based at Newcastle Under Lyme. The contractor for both projects was Climate Heating and Plumbing Services Ltd
Martin Sharman, who heads up Cool-Therm’s Midlands office, said: “The arrival of the new F-Gas Regulation, and the publicity in the run-up to the agreement, has highlighted the question mark over the long-term future of traditional HFC refrigerants, and people are quite understandably looking for alternatives.”
