Being part of the solution to HC Heat Exchangers client ’ s needs , a particular example of this was the need to accommodate the limited plant room space available on the allocated deck , without compromising performance . Working side by side with the contractor and consultant they were able to design a purpose-built compact hybrid unit to match both the capacity and space requirements .
Originally , considerations had been towards a chilled water system , but because of the long lead time required in getting chillers into the country and the additional electrical load of these units , TCE had to look at greening the installation as far as possible and thus partnered in developing the packaged VRF system . This newly-developed packaged VRF system has since become an accepted system for other installations of the same nature , as well as specialised applications in Africa .
The fabric ducting into the gymnasium area ( supplied by Fabric Air ), something seen on the international level for more than 30 years is not very common in South Africa , and is in fact a brilliant product for this application according to TCE because it produces a constant cooling system right the way through the large open auditorium and the return air is ducted back directly to the packaged unit that is mounted on the high-level service platform deck at the back of the building .
