Daikin UK, SEER, SCOP

With the first stage of redefining how the energy efficiency of air-conditioning equipment is defined arriving in January 2013, Graham Wright of Daikin UK warns that industry professionals must take note of the new approach and its implications on future design and specifications.

Johnson Controls has developed an approach to managing centralised chilled-water installations as a single integrated system that can reduce energy consumption by up to 15%. Called Central Plant Optimisation (CPO), it combines innovative control technology and advanced algorithms that enable chiller plants to maximise their efficiency by determining the correct operating parameters in real time to meet the building’s cooling load with minimum power.

Daikin Europe has developed an online controller that can be used with a wide range of its split air-conditioning units. The scope of this controller extends from residential users to the manager of a chain of shops requiring control of groups of units. This controller is compatible with selected Daikin split systems such as Emura and Nexura, as well as other wall-mounted, floor-standing and ducted systems.

AET, absoption chillers

Direct-gas-fired absorption chillers from AET can supply chilled water and hot water according to the requirements of the building. The advanced design of SAB-DF chillers ensures they are economical to install and run. They use an innovative flow system for the cooling water to provide a large temperature differential on the chilled-water and cooling-water circuits to reduce flow rate.

Durapipe, chilled water

Chilled water from chillers in the £25 million redevelopment of Stockbridge Village in Merseyside is carried from chillers to air-handling units by Durapipe SuperFlo ABS pipework in sizes up to 110 mm. The AHUs in turn provide air conditioning for the primary school and leisure-centre buildings of the project. There is also a swimming pool, state-of-the-art gym and leisure facilities, and a learning resource centre.
