A first for Sanyo

The first UK installation of Sanyo’s ground-breaking gas-powered VRF air conditioning system, which generates its own electricity, is taking place at Suffolk One, a state-of-the-art 16-19 centre of learning in Ipswich.

The landmark £65m building, now under construction by main contractor ISG Jackson, is one of the largest building projects ever undertaken in Suffolk. It is designed to provide an inspirational learning environment and will accommodate 2000 students when it opens in September 2010.

In addition to being the first building in the country to use Sanyo’s G-Power co-generation technology, Suffolk One also becomes the largest site in the UK employing the company’s gas-powered heat pump VRF air conditioning.

The £11m M&E installation on the project is being managed by leading building services provider, Inviron. All air conditioning equipment for the project, with a combined cooling capacity of 1.2MW, was supplied by Sanyo distributor ESS. It is being installed by Adcock Refrigeration and Air Conditioning.

Given the scale and distributed nature of the building, it requires 19 GHP VRF air conditioning systems and 16 high efficiency split systems. The units are mounted primarily on the roof, in groups serving five clusters which connect and surround the core of the building.

The building uses a total of 310 fan coils, mainly ducted units for concealed mounting in ceiling voids. These are augmented by a small number of ceiling cassettes. All equipment operates on high efficiency R410A refrigerant.

The VRF systems include both two and three-pipe technology, the latter used to harness significant quantities of waste heat generated within glass-clad parts of the building and transfer it to areas requiring heating.

ESS worked closely with the building services consultant on a design that delivers an exceptionally high quality indoor environment for staff and students, using the latest technology and sustainable approaches.

Leon Sunkin, director of ESS, said: “It is a superb project and a first class showcase for the latest Sanyo technology. There is no doubt that in terms of sustainability, efficiency, cost-effectiveness and quality indoor environment it delivers in all areas.”

He added: “Given the educational purpose of the building, a key design issue was low sound levels. The libraries and classrooms require a very low level of background noise, which was comfortably met by the advanced Sanyo equipment selected.”

ESS provided expert technical back-up to installer Adcock Refrigeration and Air Conditioning throughout the installation of the project. This included the provision of colour-coded drawings to help speed up work and avoid potential problems on site.
