The Hong Kong Polytechnic University, Kowloon, Hong Kong

Dr. Deng Shiming 鄧仕明

Associate Professor and
Associate Head of Department

Dr. Deng Shi-Ming graduated from Tong-Ji University, Shanghai, China, with a bachelor degree in HVAC Engineering in 1983. He then worked for three years in Shanghai as an HVAC consulting engineer. In 1991, he obtained his PhD in Environmental Engineering from South Bank Polytechnic, UK. He joined The Hong Kong Polytechnic University as a lecturer in 1992 and is now an Associate Professor in the Department of Building Services Engineering. He is a member of The Hong Kong Institution of Engineers (HKIE), and American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).

Research Interests

Dr. Deng's research interests include: direct expansion (DX) air conditioning and refrigeration system simulation and control strategies development; applying air conditioning and thermal comfort in sleeping environment in tropics or subtropics; building energy use performance analysis including building energy audit and benchmarking (in particular for hotel buildings). Dr. Deng has published totally over 70 papers. Currently, Dr. Deng leads a research group of DX and residential air conditioning technology, and there are three PhD students and a few master students working in the group. Recently, with the support of a large equipment fund from the university, the Laboratory of DX Air Conditioning Technology has been set up in the department. Over the years, the total amount of research grants from various sources exceeds five millions Hong Kong Dollars.

In addition, based on extensive research experiences, Dr. Deng has carried out a number of high-level consultancy projects related to building energy audits, HVAC systems performance evaluation and optimization, etc.
