The Christchurch Hospital Oncology building was built in 1990 and has 2 carrier chillers and 2 Muller cooling towers. Canterbury District Health Board (CDHB) now need to:
• Replace one of the carrier chillers and one of the Muller cooling towers and upgrade them to modern technology and more efficient compatible plant; and
• Replace the pipe work, pumps, valves and controls.
CDHB will be replacing the existing chiller and cooling tower with:
• 1 x Smardt-Powerpax 300kW WA027.1 chiller; and
• 1 x Evapco LSTE419 water cooled cooling tower.
The chiller and cooling tower will be purchased and delivered to site by CDHB. The Contractor should allow for the required crane lift to locate the chiller and cooling tower into the plant room and to remove existing obsolete plant.
Due to the CDHB requirement for a robust Building Management System (BMS) the new plant is to be fully integrated and compatible with the existing BMS. As such CDHB require that SetPoint Solutions Ltd are engaged by tendering contractors as part of this project.
The controls, pumps and valves will be upgraded to have the best control and monitoring over the tower in conjunction with the chiller to get the most economical returns.
CDHB cannot take down the services we supply for any length of time. Therefore the changeover of the chiller and cooling tower will take place in the cooler months.
The proposed project plan includes:
• The old cooling tower and chiller will be isolated;
• Wiring, sensors, motorised valves and pumps removed;
• Simultaneously take the roof off with a temporary tarpaulin arrangement installed for ease of removal and less down time on the project;
• The old tower and chiller will be lifted out from the plant room and the new chiller and tower would get lifted back into the plant room;
• The temporary roof would go on while the location is prepared for both new pieces of plant;
• Fit the new chiller and tower;
• Modify the roof to accommodate the new tower and reinstate; and
• Install new pipe work to transition back on to the field pipe work along with new valves, wiring, pumps and sensors for both pieces of plant.
• Integrate with CDHB Building Management System (BMS)
• Commissioning, testing and hand over.
In 2015 CDHB and their consultants carried out:
• Mechanical design;
• Structural design; and
• Architectural design.
