MHIAE
High effi ciency air conditioning equipment manufactured by Mitsubishi Heavy Industries Air- Conditioning Europe (MHIAE) is helping to breathe life into a derelict former bus depot in London. The Hackney Depot project, the fi rst in London by 6AM Development, involves the revival of a long- abandoned 2000m² space above the depot which is now dedicated to local creatives, and aims to help redress the decline of maker space/ light industrial facilities across the capital.
Kent-based air conditioning specialists, Doveley Air, specifi ed and installed a system that was in keeping with the ethos of the project, low global warming potential products were selected that operate with R32 refrigerant and can still provide heating at -20˚C ambient temperature. System effi ciencies are as high as ERP A++ with energy effi ciency ratios and coeffi cient of performance rated as high as 4.49 and 4.37 respectively. A collection of 4-way cassettes of varying capacities are spread throughout the building, each connected to an MHIAE RC-EX3A eco-touch screen wired remote controller. Ease of use is supported by the two programmable function buttons located on the front of the controller which allow quick access to functions such as energy saving setback modes and particular operating modes. System effi ciency is improved, and operating cost reduced with additional motion sensors that are installed in the cassette fascias. These motion sensors can be set to either adjust desired room setpoints depending on occupant movement or used to place the unit in standby. Doveley managing director Peter Notley said price, reliability and backup were key reasons for specifying the MHIAE equipment and described the installation and commissioning to date as “a lovely straightforward job.’’ He added: “Quality and reliability are the main reasons I use MHIAE equipment. If it wasn’t quality, I wouldn’t put it in.
“One of the key selling facts with our customer was running costs. It does what it needs to and he is very happy with the heating it is providing, because it’s colder in the building than outdoors. We have used motion sensors for the fi rst time with MHIAE equipment because of the energy-saving benefi ts to the customer.”

Condair
Humidity control specialist, Condair, is off ering a free 10-point guide to specifying dehumidifi ers. The document covers the main issues surrounding planning and installing a commercial dehumidifi cation system. It includes information on system design, product sizing, drying psychrometrics, energy saving and much more. Dave Marshall-George, sales director at Condair explained:
“This guide has been produced by experts in the fi eld with experience spanning thousands of drying projects. It gives unbiased advice on both desiccant and condensing dehumidifi ers. Written in an easy-to-follow style, the 10-point format makes it a very accessible reference tool for any HVAC consultant, installer or facilities manager. “Planning a dehumidifi er project can be a complex undertaking due to all the parameters than need to be considered. Dehumidifi ers don’t just remove moisture from the air but also generate heat during the drying process. Managing an area’s humidity often involves consideration of its temperature control too, and this 10-point guide walks the reader through the psychrometrics of this, as well as strategies to deal with it.” Marshall-George concluded. Condair’s 10-point guide to specifying dehumidifi ers is available free to download.
