Free Cooling by Cooling Towers of Water-cooled Air-conditioning System

I&T Wish Free Cooling by Cooling Towers of Water-cooled Air-conditioning System
(REF : W-0057)
Summary and Challenges

Every year, there are several months with relatively low temperature and low relative humidity In Hong Kong. Currently air-conditioning systems are operated to cater for internal heat even in these colder months, resulting in energy wastage.

This project aims to develop a water-side free cooling system whereby weather and operation data will be collected and analysed to build an optimisation algorithm of free cooling in Hong Kong. A two-year pilot scheme will be introduced to collect data over the winter months for algorithm development and verification.
Expected Outcome This project aims to develop a water side free cooling system by cooling towers for energy saving.
Expected Trial Duration 24 months
