ABSTRACT: With the increase in the number of large property projects in Malaysia, district cooling system (DCS) projects are being seen as a viable option to meet air-conditioning needs. The attractions are obvious: savings in floor space, otherwise occupied by conventional chiller plant room, for more commercial space; better economies of scale; cost savings through energy-saving technologies; and better reliability. On the other hand, the following are some of the difficulties encountered in the development of DCS projects: · Convincing users the correct economics of DCS versus conventional systems; · Requirement of a minimum cooling load to achieve enough economy of scale; and · Uncertainties arising from phased development needed to match property take-up. This paper presents several DCS schemes as well as relevant economics, and highlights some of the issues faced by the developer of DCS projects. Particular reference will be made to the DCS project currently being implemented in the Kuala Lumpur Sentral Development.
