Technical Webinar – OPjD Replacement Chillers

Date : 14 Dec 2022
Time : 6:30 pm to 8:00 pm
Venue : Online Meeting via Microsoft Team

Chiller is the central primary refrigeration equipment to supply chilled water for different air-conditioning systems. It is an essential system to provide thermal comfort to passengers as well as optimum air condition to facilities. There are over 340 chillers operating in MTR stations and depots and planned to replace when they have been reaching target life over 20 years. In this project, total 154 existing chillers among 35 stations and 4 depots in 7 lines have been replaced with high energy efficient ACCs or Water-Cooled Chillers (WCC) within 2017 to 2022. With a year early completion, over $30M recurring energy saving and reduction of 20,000 CO2 can be achieved earlier as well. The Seminar will introduce the design and replacement strategy of newer and smarter chillers as well as the construction challenge of the chiller replacement project encountered.
