COOLING | NEWS TOSHIBA AIR SUPPLIES AIR CONDITIONING FOR SOLENT UNIVERSITY SPORTS COMPLEX A new sports complex opened as part of Solent University has been specified with a variable refrigerant flow air conditioning system from Toshiba Air. The facility comprises two sports halls, three studios and an exercise therapy space, and was designed to achieve a Breeam Excellent rating. The project combines Toshibas threepipe heat recovery SHRMe and two-pipe SMMSe VRF systems, plus Toshiba Digital Inverter splits and applied AHU-DX combined coil systems. Along with a CIAT Floway DX system, these provide the complex heating and cooling requirements of the multiple sports spaces within the buildings. Toshiba Carrier UK is a joint venture between Toshiba and Carrier in the UK, and is part of Carrier, a supplier of heating, ventilation, air conditioning and associated services. Historic Bratislava castle installs HVAC basement A historic castle in Bratislava, Slovakia, has benefited from a new HVAC basement, as part of an extensive eight-year refurbishment. Gntner has installed seven of its Vertical Vario GFV units, with an overall cooling capacity of 1,400kW, in the castle. The fans of the fluid cooler are virtually flush-mounted into the wall and project into aneighbouring room. From there, the heated air is dissipated to the environment via ceiling grids. The Gntner Vertical Vario fluid coolers cool a 34% ethylene/glycol solution from 46C to 41C. The dry coolers use an energy-efficient, partial-load operation that makes particular sense when there are no visitors to the museum and no events going on inside the castle. Daikin UKs recycling initiative puts reclaimed refrigerants on the agenda New service encourages re-use of refrigerant from existing buildings Heating and cooling specialist Daikin has introduced initiatives to increase the use of reclaimed refrigerants. Launched last month, the scheme involves: the allocation of certified reclaimed refrigerant in certain VRV systems; the use of reclaimed refrigerant in Daikins commission with confidence service; and the launch of a new reclaim with confidence service, in partnership with A-Gas. The new VRV IV+ systems and existing VRV IV S-series units now have certified reclaimed refrigerants allocated to them during production so these units have no impact on F-Gas quotas. Daikin marketing manager Martin Passingham said: Reclaimed refrigerants could be your best defence against the F-Gas regulations. Reclaimed refrigerant avoids the CO2 emissions that are produced when manufacturing refrigerant. The quantity of reclaimed refrigerant allocated to these units avoids more than 300,000 tons of CO2eq being generated in the production of virgin refrigerant, he added. A new compressor for the VRV IV+ delivers an average 15% increase in seasonal efficiency over the previous ranges of Daikin VRV systems. According to Angela McGinley, managing director for Daikin UK, the reclaim with confidence service will help to ensure a greater supply of reclaimed refrigerant re-enters the market. It forms part of Daikins commitment to providing safe and healthy work environments, asthe business strives to become carbon neutral by 2050. Carrier adds leak monitoring to range Carrier has released an upgrade to its AquaSnap 30RBMP30RQMP chiller range that includes built-in connectivity forfixedrefrigerant-leak monitoring and Carriers Touch Pilot control system. The upgrade adds significant new capabilities that make the chiller easier for end users and maintenance contractors to operate. It will also help to reduce the cost of ongoing maintenance by automating the checks required by F-Gas regulations. www.cibsejournal.com July 2019 45 CIBSE July19 pp45 Cooling News.indd 45 21/06/2019 17:20
