We were approached by Oxford University to replace an existing 400Kw Carrier water chiller in one of the campus buildings that had reached the end of its economical life cycle.
The building has a 24hour year round requirement for cooling and we had to come up with a way of maintaining cooling whilst the chiller was replaced.
This was achieved by the installation of a temporary water chiller and pump set mounted externally at ground level and connected by flexible pipe work to the building chilled water circuit, the existing chiller was then isolated and the temporary chiller commissioned and made operational, this was left running for several days to check reliability before the existing chiller was de-commissioned.
Due to the construction of the building we were unable to lift the existing chiller through the roof aperture and it had to be de-commissioned and broken down into smaller manageable sections.
The new chiller had to be carefully selected for its technical suitability and physical size, a Daikin unit was eventually chosen with a clearance of 40mm either side of the existing aperture.
On the day of installation a large crane was positioned outside the building, the old chiller was removed in sections and taken from site for safe disposal, the new chiller was carefully lifted from the delivery vehicle and checked for vertical alignment as we only had clearance of 40mm either side of the roof aperture.
The lift proceeded and the chiller was installed onto its base with no issue or complications, the pipe work was then re-connected and the chiller commissioned.
