Past Projects

Warrington & Halton Hospitals

Following on from the success of the Natural History Museum project we worked again with energy specialists Cynergin to delivery energy saving work on two busy NHS hospital sites. The £1.8M D&B project was carried out in 2013/14.

 

These heating systems present two, often conflicting challenges. We must satisfy the load, but at the same time keep the return temperature down to prevent the CHP unit from dumping heat. This needs close control of the system.

 

Changing over the heating system in a hospital is not easy and the task was made more difficult when the programme slipped from the summer to winter period. On both sites we were able to design the new system to connect onto the existing systems without the need for shutdowns.  The pipework was arranged so that the changeover simply required the operation of just four valves. The shutdown time was reduced to just a few minutes, just enough time to allow the system pressures to equalise. We could then prove the operation of the new system before the old plant was removed.

 

At Warrington Hospital our works included:

• Extend the centralised MTHW heating system to cover 3 additional buildings on the site.

• Covert existing pumps to variable speed drive.

• Replace large parts of the site wide BMS system to give us close control of the system.

• Construct a new substation and alter the hospital HV system to accommodate a new CHP unit

• Install mechanical and electrical services for a new CHP unit.

• Refurbish an old steam boiler room to house the new CHP unit. This included removal of asbestos from the walls, cleaning and filling old service trenches and a new roof covering.

 

At Halton Hospital our works included:

• Alter an old incinerator plantroom and stores area to construct a new energy centre.

• Install a new central boiler plant system including new distribution mains around the site.

• Connect three existing systems to the new central.

• Construct an external compound for a CHP unit.

• Install mechanical and electrical services for a new CHP unit.

• Install a new BMS system to control the new plant.
