Condair


Condair has developed a new app that accurately determines how much energy could be saved by using in-duct exhaust air evaporative cooling and a heat recovery system, rather than just traditional compressor driven cooling. Using weather data from Meteonorm, the myCoolblue app calculates how much energy is needed annually to cool a building. Then, taking into account 10 years of historic weather data from over 300 regions worldwide, it projects how much cooling each month could be delivered using exhaust air evaporative cooling and how much would still need to be delivered using traditional mechanical cooling. By assessing how much of a building’s cooling can be delivered with exhaust air cooling, a HVAC consultant can ac- curately calculate the viability of an in-duct evaporative cooling system and show its return on investment potential. Project details and calculations can be saved to the cloud and accessed later. Condair’s myCoolblue app can be downloaded from the App Store for


free and is available for iPad only. www.condair.co.uk


Gilberts


Gilberts Blackpool has completed the installation of new louvres to all four sides of the BBC Media Village site’s dedicated Energy Centre, to ensure the eight chillers on the roof now have adequate air circulation. The 7,700m2


Energy Centre provides power, heating, cooling and other


services to the entire 17 acres Media Village site. The majority of the chillers installed in 2009 needed premature replacement, as an existing, rendered blockwork wall was restricting the passage of air. The solution to the restricted ventilation issue has been to remove large sections of the wall and replace with banks of Gilberts’ Series 27 acoustic weather louvres secured and supported on a steel framework. Main contractor Wates Smartspace used the Gilberts’ louvres to create four steel screens around the facades, approx 270mm deep, with sizes varying up to 3.6m high x 24m long,and totalling 247m2


CDL


Cool Designs has launched a sophisticated new air conditioning controller called OASIS, which cuts energy use and optimises indoor comfort at individual room level across a building. It can be used with Toshiba’s full commercial range of splits, heat pumps and VRF systems.


Oasis is based on an advanced algorithm that takes account of ambient outdoor conditions to minimise system running time, while delivering rock- steady comfort conditions for occupants in all parts of a building. It also takes care of fire and frost protection and provides a power metering and recording capability. Data gathered can be used by building owners and FMs as part of an energy management programme. Users and contractors can access the system via a number of interfaces, including an on-site touch-screen for direct local access, and smart phone or a standard web browser for remote access. The modular system is available for use with 64 and 128 indoor units, which can be linked together to suit any scale of Toshiba project. www.cdlweb.info


Big Foot . Series 27 louvres are part of the firm’s


comprehensive range of acoustic weather louvres that directly interface into steel frameworks or the building façade. www.gilbertsblackpool.com


Airbloc


Airbloc, part of Nortek Global HVAC (UK) Ltd, a leading European developer and manufacturer of energy efficient radiant and warm air heating systems, has launched a new common controller for the AC and ACR range of air curtains. The new common controller will replace


the current AC Panel and the Smart Elec panel.


This will allow all heat mediums including air curtains fitted with Smart Elec PCB to be controlled using a single common controller. The intelligent controller automatically detects the type of air curtain it is communicating with and adjusts its user menus to suit. Simple to programme and operate, the new common controls platform


can control up to 16 air curtains of a single type and the new RJ45 connection gives the user a more stable communications link that can operate up to 150m from the air curtain. www.ambirad.co.uk

Big Foot Systems has supplied support solutions, including bespoke air handling unit supports, for rooftop plant at a new health and Bbosciences building on a university campus. The project required both air handling units and external condensers for cooling. The challenge for the contractor was installing the large air handling units (AHUs), duct and external condensers in a confined area and without penetrating the roof. Big Foot Systems provided the ideal solution with its range of non-penetrative building services rooftop support. A standard support frame was not feasible for the AHUs as a specific finished height was required while still allowing for serviceable access underneath. Instead, Big Foot Systems supplied individual 600mm feet with a fabricated top bracket to receive AHUs continuous skid, made feasible with the roof’s integrated wind protection. In addition, associated duct and pipe work were supported by large quantities of Big Foot Systems’ 305mm H Frames. Later on in the project, Balfour Beatty also required a further support solution and so used HD Frames, also from Big Foot Systems. www.bigfootsupport.com


Gilberts


For Theatre by the Lake in Keswick’s new £700,000 café, architect Aedas focused on a design that was sympathetic to the building’s location by Derwentwater: wood, natural light and natural ventilation prevail in the monopitch structure.


Gilberts Blackpool has delivered the natural ventilation strategy, focusing on three of its Mistrale WHF75 flanged high weather performance louvres, integrated at high level into the wall at the lowest point of the roof, behind the kitchen area. Each of the louvres features Gilberts’ integrated VN75 volume control dampers. One of the louvres, also includes an LPHW coil, to make up air to the kitchen extract. Gilberts’ Mistrale 75 is designed to provide smooth, accurate and stable airflow. The system attains a U value of 0.96W/m2 leakage less than 5m3


/K, with air /hr/m2 . The 75mm blade pitch of the core WHF


louvres delivers high performance with Class A weatherability, and a free ventilation area of 50%.
