CIAT high efficiency packaged heat pump systems have been chosen to cool a new generation of lithium battery power stations being built in the UK and Ireland.

The facilities will each include 12 CIAT Vectios reversible heat pump packaged air conditioning units, with a combined cooling capacity of 340kW.

The power storage plants are part of strategic plans to improve the resilience and security of the electricity supply used to support the national grid. Following a successful 10MW pilot plant in Ireland commissioned in 2016, the design was scaled up to 60MW and is being rolled out in three locations (20MW per site) in England.
Effective cooling of the batteries is critical during charging and discharging to maintain efficiency, optimum operation and to prolong working life. The lithium power plants are fitted with a bespoke air connection system to ensure rapid and efficient coupling between the units and the power station air intakes on site.

The compact CIAT air-to-air horizontal-design systems supply large volumes of cool air within a consistent temperature and humidity range. Treated air is ducted into the power station’s cold aisle at a temperature of 17.3 degrees Celsius and 96% relative humidity (RH), mixing with present latent air before being drawn over the batteries by onboard fans, before being returned to the air conditioning units at 29 degrees Celsius and 50% RH.

CIAT UK worked with Belfast-based distributor Aircon Sales and Service and the Balance of Plant contractor Scotts Electrical Services  to ensure the precise cooling needs of the project were met.

Ian McFerran, managing director, Aircon Sales and Service, said: “The battery-based power stations are a revolutionary approach to providing stability and resilience to the national grid. For example, in the event of a lightning strike or cable fault, they connect to the grid in milliseconds to ensure a stable supply. They also provide the essential capacity to store power generated from renewable sources, such as wind and solar, until it is needed.”

Gordon Nixon, managing director, Scotts Electrical Services, said: “Maintaining the batteries within their design parameters is vital to ensure they work efficiently and effectively throughout their design life cycle. The CIAT Vectios units are based on high quality engineering with an efficient design using reliable cooling technology, which provides an ideal solution for our critical application.”

A Rund air curtain at the 1Rebel gym in London's Victoria
JS Air Curtains has supplied two Rund air curtains to a boutique gym in London.
 
With two entrances into reception, the 1Rebel gym building in Victoria was suffering from a wind-tunnel effect and wanted to eliminate the draught to maintain a comfortable internal temperature for staff and customers. 
The Rund air curtain was chosen by architects who felt its cylindrical design complemented the industrialised and futuristic interior, and could be suspended with inverted goal-post like supports. The units were installed by mechanical contractors, TMI Mechanical , who also provided the ceiling mounted suspension arms.
 
Nina Shadi, general manager and trainer at 1Rebel UK, said: “Since the air curtains have been installed, we’ve noticed a considerable improvement in the internal environment. We no longer experience the draughts through our wide doorways and the temperature is much more pleasant.”
 
The Rund air curtain has rounded casing that comes in white or silver as standard but can be supplied in any RAL colour or with a brushed stainless steel finish. It can be suspended horizontally above a doorway, as it is at 1Rebel, or vertically at the sides of an entrance. When mounted horizontally, it has many different suspension options, including goal post-like arms fitted to the floor, wall or ceiling.
 
Low noise, centrifugal double inlet fans are driven by an external rotor motor. The powerful fans are capable of providing enough airflow to create an effective seal across doorways up to 4.2m high or 8.4m wide, when mounted vertically at each side.

21 Dartmouth Street ©Nicholas Worley
TROX UK has supplied the air conditioning solution for a prestigious redevelopment project in London.

The 21 Dartmouth Street building is in the heart of St James’s Park, between Buckingham Palace and the Palace of Westminster, and offers 53,000 sq ft of office space.
Main contractor, mac group, and M&E services consultants, Max Fordham, required a solution which would combine optimum comfort conditions with outstanding environmental performance.

Air handling
At the heart of the system are two TROX X-CUBE air handling units. Each X-CUBE incorporates TROX’s integrated controls package, whereby damper actuators, pressure, temperature and humidity sensors as well as heat recovery control and fan control strategy are linked into the digital control network. Both units incorporate thermal wheels with pre-programmed strategies, selected to meet BVU efficiency in accordance of the ErP 2018 standard. This is the highest level of smart technology, combining pre-set algorithms, developed by TROX, to facilitate rapid reactions to changes in building load.

Zone-based VAV control
To deliver high levels of comfort and energy efficiency, the system utilises TROX’s X-AIRCONTROL variable air volume functionality. This is integrated with the X-CUBEs and with a TROX X-AIRCONTROL Zonemaster to address the needs of the different occupied spaces across the site. The building is divided into 20 X-AIRCONTROL zones, each of which has a TROX TZ Silenzio supply controller and a TROX TA Silenzio extract controller. The X-AIRCONTROL zone modules combine information from humidity, temperature and PIR sensors and ensure the perfect interaction of all air handling components in a room. The system recognises all digital sensors automatically and uses measured values to initiate control procedures.

The modules also collect information from air quality (VOC) sensors, which can be an invaluable tool in refurb projects, where large amounts of volatile organic compounds can remain present due to new furnishings/fittings and decorative work. Whilst the VOC sensor does not measure CO2 directly, it measures VOC’s exhaled by human beings which are directly proportional to the amount of CO2 exhaled. The VOC sensors detect many potentially harmful compounds (unlike simple CO2 sensors) and can communicate with the system to change the air flow rates, increasing them until acceptably low VOC levels are reached, and reducing again once the compounds have sufficiently dissipated.

 The 20 zone modules are integrated with the TROX X-AIRCONTROL Zonemaster. This intelligent controller provides a single point connection to the BMS for all of the zones via Modbus TCP or BACnet IP. For larger systems it is possible to connect five Zonemasters together, creating a network of up to 125 zones.

Energy efficiency and acoustics
The system supplied includes a fan optimisation strategy, controlling fan speeds based on damper blade position, which enables energy consumption to be reduced significantly. The Zonemaster monitors the position of all damper blades on the system and adjusts fan speeds in response to changing demands in each zone of the building, ensuring that fans are never operating at a higher level than necessary to meet demand. This provides significant energy savings compared to conventional fan speed control where the fan is commissioned to deliver a maximum system pressure at all times. Another advantage of the reduced system pressures/fan speeds is a reduction in noise.

Practical considerations
To ensure that the building was ideal for IT-intensive office premises, TROX Silenzio air supply and extract units were selected for each zone. These units can obtain an accurate airflow measurement without the requirement for lengths of straight air duct in advance of each module. This reduces the space and ducting requirements, making it easier to integrate the units in a congested ceiling space.

Ian Thomas, product technical manager – air products at TROX UK, said: ‘Increasingly, designers of HVAC systems for prestige commercial properties are exploiting the advanced control capabilities incorporated into the air handling equipment itself. This provides an extremely effective alternative to bespoke programming of the BMS, and delivers increased levels of zone-based control for occupants of the building. The 21 Dartmouth Street project is an excellent example of this approach, and we are proud to have played our part in the redevelopment of this prestigious site.’’

Lennox says the latest additions to its range will include the world's first inverter scroll chiller for use with R32.

The extended line-up is said to offer more options for installers and engineers who wish to move away from R410A and R134a to low-GWP alternatives.
New additions to Lennox's eComfort scroll chiller range will give HVAC professionals the chance to use R32 for smaller applications, from 170 to 400 kW. The variable-speed eComfort inverter scroll chiller also claims significantly improved seasonal efficiency, exceeding EcoDesign 2021 standards.

The new Genesis screw compressor chiller range includes options for both R134a and R513A/R1234ze, aimed at helping installers and engineers manage refrigerant phase-down in larger applications.

Alongside the low-GWP options, both Genesis and eComfort ranges will continue to provide support for R410A and R134a. 

Florian Beduchaud, chiller product manager at Lennox EMEA, said: "Today, consulting engineers want clear alternatives to R410A and R134a, which, due to the phase down, have become more expensive and difficult to source.

"Although R410A and R134a are not banned, many installers are keen to switch to take advantage of lower taxes and leak-testing requirements. R32, R513A and R1234ze are the best choices, and introducing these options early gives our customers the best chance to plan their transition at their own pace.''
