New air‐cooled inverter scroll chillers from LG


Earn CPD Hours with


Products PLC’s ‘An Introduction to Air Distribution’. On the course, attendees will hear from one of


F


Waterloo’s air distribution experts. They include Andrew Wardle, Northern Sales Manager, Alex Macfarlane, Southern Sales Manager, Alan Smith, Commercial and Export Markets Manager, and Roy Nutley, Technical Advisor. The course covers the basics of air distribution including typical air movement effects, cooling systems, the effect of heat gains, alternate systems and selection guidance. “It’s so important to share knowledge and


information with industry peers,” says Rick Edmondson, Chairman at Waterloo. “Working collaboratively doesn’t start or end with each project. It’s an ongoing process to ensure people who work in our industry have access to the best information possible. “It’s great that we can now support consultants,


contractors, specifiers, architects and building engineers with their CPD and help them to earn hours towards it. We’re looking forward to welcoming people to Waterloo, and for them to learn about the importance of air flow and the effect it can have on an internal environment.” Waterloo’s course is approved by the CIBSE CPD


Approval Panel, they said: “Just read the Waterloo intro to air distribution. What a great CPD presentation, easy to understand and all the basic principles and system types covered. An exemplar worthy to be on our directory.” The presentations will be followed by a Q & A and


the course is free to attend at Waterloo’s head office in Kent, at its Manchester office, or it can be held at customer’s premises too. To book your place, visit

L


G has launched a range of air‐cooled, inverter scroll chillers into the UK market. The new heat pump and


cooling only options are available in 60kW, 123kW and 185kW (cooling capacity) models. This new chiller range offers superior performance and, alongside industry energy efficiency in ‘part‐load’ conditions, the Inverter Scroll Chillers boast an impressive EER 2.65 / COP 3.2 / ESEER 4.79 . They are compact, with a foot print


area of only 4.9m2, ideal where space is at a premium. The LG units feature low noise ‐ at just 68dB(A) and can offer reduced noise levels at night, simply by adjusting the fan RPM. HVAC systems are generally sized at their


peak efficiency when they are working at maximum capacity, which only occurs less than 5%of the systems operational time. This is highly inefficient when most units operate mainly at partial load. So it is important to check part‐load efficiency. At part‐load, when cooling output can be reduced, inverter chillers can operate linearly with a wide operational range, becoming more effective than chillers operating at a constant output. Efficiency can clearly be improved whenever the compressor speed can be reduced to more closely match the load. With LG’s designed and manufactured


inverter scroll compressor boasting higher energy efficiency in overall operation range especially in part‐load, this reduces operation costs for the end user. Equipped with LG’s exclusive Ocean Black Fin anti‐corrosion coating, the inverter scroll chillers heat exchanger is protected to reduce the effects of corrosion normally found in coastal and industrial environments.

Fascia panels can be custom made in many different materials, screen printed to carry logos or images, and manufactured to incorporate elements such as clocks and LED displays. Materials designers have specified on custom Zen fascias range from stainless steel, wood, PU leather, high impact polystyrene and PET, each chosen to perfectly match the architecture of the entrance. As the fascias can also be provided with vinyl graphics, fire exit signs and illuminated 3D lettering, the possibilities are limited only by the designer´s imagination.

jointing system and easy‐to‐use design, the pipe is both simple to install and durable. Steve Richmond, Head of


Marketing & Technical at REHAU, said: “Being the only product of it’s type both manufactured and sold in the UK, we are thrilled to have seen RAUVITHERM grow in popularity over the last few years. “It was an easy decision for us


to set up production of RAUVITHERM in our Blaneau factory five years ago. Having production in the UK meant that we would significantly reduce our


carbon footprint and be able to respond quickly to customer demands. We have also invested in tools for 140mm and 160mm RAUVITHERM production in 2016 which have proved popular already with customers. RAUVITHERM is available in


UNO 25‐160mm and DUO 25‐ 63mm. Installation is easy and time‐effective due to the REHAU compression sleeve jointing system. The piping is leak‐proof and has WRAS approval for potable water applications.

monitoring, schedule control and demand control. It can also be installed up to 500m from the chiller d. One controller can be used to control up to 5 units of chillers, saving both time and money. A maximum of 10 chillers can be controlled remotely by central controller and direct BMS communication, up to 1,850kW. Continuous heating minimises the


decrease of water outlet temperature during defrosting for multi circuit models. The back‐up operating system helps the


entire HVAC system to continue to operate by removing compressors or system circuits from operations until repair or diagnosis is complete. For more information you can email LG at

circuits increase operational reliability. Four scroll compressors guarantee energy efficiency, even in small partial load stages. With the WPAmini, STULZ is


expanding its product line of air‐ cooled chillers. The compact chillers deliver a cooling capacity of up to 160 kW and have been optimized for use in data centers or industrial cooling. The chillers are equipped with two redundant refrigerant circuits to increase operational reliability. The circuits are controlled according to the required cooling capacity, so that the respective circuit is activated with maximum efficiency when minimal cooling is needed. The WPAmini is equipped with oversized aluminium microchannel condensers and four scroll compressors, which are activated and deactivated (25, 50, 75, 100%) in stages. The compressor operating time can be reduced to a minimum using the Free Cooling functionality that can be incorporated as an option. This considerably cuts both power consumption and operating

costs. Three operating modes are available in all: DX mode, Free Cooling mode and Mixed mode. In Mixed mode, cooling capacity is generated by means of simultaneous Free Cooling and compressor cooling. In this way, significant energy savings can be achieved even at moderate outdoor temperatures. For noise‐sensitive locations,


the WPAmini is also available in a "Low Noise" configuration. Here, the compressors are enclosed in a special sound‐insulated casing, which lowers the volume to normal conversation level. The chillers can also be fitted with optional fan diffusers, which further reduce the noise level as well as electricity consumption. The WPAmini can run in extreme climates. Its operating limits range from ‐40 to +50 °C, depending on the model. The switch gear cabinet is generously sized at the factory, ensuring sufficient space for optional electrical equipment. There is therefore no need for additional switch gear cabinets or extensions, with the interface problems these sometimes entail. Furthermore, the WPAmini series satisfies the requirements of Ecodesign or ErP Directive Stage 2018.
