Case Studies

Project: Cantay Office and Conference Centre, Park End Street, Oxford

Works undertaken: The design, supply and installation of VRF air conditioning and heat recovery ventilation

Our brief was to find an energy efficient solution to the cooling, heating and ventilation requirements of the numerous conference rooms and office areas as part of a complete refurbishment project in Oxford.

Our solution was to install Mitsubishi GUF units which provide a combination of heat recovery ventilation, cooling and heating all within a single unit. The integration of the ventilation and air conditioning functions into a single unit saved valuable installation space within the ceiling voids allowing additional space for other trades.

Most importantly was the heat recovery ability of the system saving considerable amounts of energy which is not only financially beneficial to the end user but also beneficial to the environment. The unit’s ability to provide free cooling when the conditions allow also reduces the running time of the cooling plant benefiting the same.

Project: Lambs Passage, London, EC1Y 8LE

Works undertaken: The design, supply and installation of VRF air conditioning to high specification apartments.

With the total requirement for 140 ducted fan coil units being required, Mitsubishi VRF systems provided the perfect solution to meet the heating and cooling demand of the building. The ability to serve this amount of fan coil units with only 14 condensing units was crucial due to the limited roof space available to locate the plant.

In addition to the above, having a single branch box per system from which pipe work ran to each apartment provided the most flexible solution in terms of ease of installation

The ducted VRF fan coil units serving each apartment were installed within the ceiling void of the rooms, distributing cooled or heated air through supply air grilles and spiral ducting.

Each apartment has its own individual controller and remote temperature sensor to allow complete end user control. In addition to this and due to the large number of fan coils and the potential access issues in the future, the complete installation is also controlled by a centralised controller. This allows the units to be interrogated without the need to disturb the occupants of the apartments.

Project: Baskerville House, Broad Street, Birmingham

Works undertaken: The complete replacement of mechanical systems as part of a refurbishment and extension.

This challenging project involved the replacement and modification of all building services as part of a contract carried out by the main contractors Morgan Ashurst

Oxford Refrigeration carried all mechanical services as detailed below:

• Above ground Drainage
• Domestic hot and cold water services
• Supply and extract heat recovery air handling units
• Local heating and cooling units supplementing that provided from the main air handling plant. Electric over door heating to the main entrance
• Complete BMS control system for all plant
• Split system air conditioning to a comms room
• Modification to the existing chilled beams and panels, serving the office areas

From the installation work Oxford Refrigeration where also successful in tendering for the continual service and maintenance directly for the customer FTC Kaplan
