Sir Samuel Way Law Courts Building
Project Description
DTEI Building Management Facilities Services on behalf of the Courts Administration Authority (CAA) engaged the building services engineers, System Solutions Engineering to provide a suitable method of replacement for the ageing chillers. The feasibility study highlighted the fact that the existing Luke chillers were at the end of their economic life.
Westside was selected to replace the chillers with the work being undertaken in 2 stages. Both stages provided an engineering and logistical challenge due to the limited access to the basement plant room.
Access to the basement plant room was provided by a prisoner transfer lift serving the basement holding cells, with a doorway opening of only 700mm. In an Australian first, BITZER were able to manufacture a modular skid frame in two pieces, one to house the high efficiency screw compressors with the second housing the plate heat exchangers for the evaporator and condenser. Westside undertook final assembly and the interconnection refrigeration pipe work, connection to the existing chilled water header and existing cooling towers. Stage 1 consisted of 3 x 200 kW compressors (as pictured below) and stage 2 utilizes 2 x 250 kW compressors
A new Building Management System (B.M.S) was installed and provides a much improved information presentation format via the user friendly graphics display, with live status of chilled water flow and all fault and alarm signals from the chillers. This control system is able to provide instantaneous energy consumption associated with the chilled water flow, and automatically rotates the operation of the chiller staging and loading of the five new compressors to provide the highest efficiency available.
Both stage 1 and stage 2 were completed on time and on budget delivering a very successful outcome to the client, largely due to the collaborative involvement of the project team.
