October | November 2020 AIR CONDITIONING 12 Volume 6 No.6 Calculations and design After initial outline drawings were submitted and the design process was started in accordance with EN 378, the cooling duty in each area was calculated to ensure that it met accurately with the requirements. There were several design considerations to be addressed such as ceiling height limitations, aesthetics, controls and A/C unit selection and fresh air requirements for each zone. Darren Cromack explained “Allan also requested a heat recovery system for the fresh air and extract for the building. Again, we went with Midea equipment and installed five heat recovery systems.” A Bacharach leak detection system was also due to be installed on site, so it had to be taken into consideration during the design process. This was to consist of 15 individual sensors; one for each air- conditioned space. Allan Harper added: “We selected the most energy ecient and compact Midea units, both suitable for the low ceiling heights and as well as being aesthetically pleasing to suit the high standard of anticipated building finishes. We made sure that these units would satisfy the cooling For information regarding this article please contact: Mel Summers, Marketing Manager, Climalife UK Tel: +44 117 980 2520 Email: msummers@climalife.dehon.com A collaboration of expertise Air Conditioning Accessories: Founded in 2004 by Richard Stewart, Leeds-based ACA has established itself as a well-regarded distributor, supplying quality service and products to its customers.

Darren Cromack reported: “There is very little dierence between installing R-32 kit compared to R-410A as the installation and commissioning process is practically identical. We will be guiding our customers towards the use of R-32 products. “On behalf of myself and my team at Glide Air Conditioning, I would like to express my gratitude to Allan and his team at Climalife UK for the compromises made and for enabling us to take a leading role in reducing GWPs within the air conditioning industry.” The equipment in action now Six months on from the original installation, Allan Harper said: “We are delighted with the finished system in the new oce as it meets all of the requirements originally laid out and has been working really well, especially over some of the hot weeks we have had. “The team managed to overcome the challenges with the low GWP A2L equipment, and we are all really happy with the final equipment choice. “At the start of the project it was interesting to see how dicult it was for contractors to focus on A2L equipment due to a lack of knowledge and availability of equipment. We are obviously very satisfied that we could find relatively quickly a solution which we think will provide the level of cooling and comfort we require today and many more years to come. We know that today there is more and more A2L refrigerant gas-ready equipment coming to the market with bigger cooling capacities and we would encourage end users and contractors to start to use A2L equipment for air conditioning applications to help meet the F-Gas regulations.”
