The Ph.D. in Heating, Gas Supply, Ventilation, and Air Conditioning (HVAC) Engineering is a research-focused doctoral program designed to train advanced professionals and scholars in building services engineering, energy systems, and environmental control technologies. Typically offered under the discipline of Heating, Gas Supply, Ventilation and Air Conditioning Engineering at top engineering universities such as Southwest Jiaotong University (SWJTU), this program is a full-time doctoral program lasting 3–5 years, with instruction primarily in Chinese, and research supervision often available in English for international students.

The program aims to cultivate experts with deep theoretical knowledge, research skills, and practical engineering capabilities in areas such as building energy systems, thermal fluid dynamics, indoor environmental quality, sustainable heating and cooling, and energy-efficient design. Graduates are trained to analyze, design, and optimize HVAC systems, natural and mechanical ventilation, gas supply networks, and energy management systems for residential, commercial, and industrial buildings.

NOTE: The university may have additional program-specific eligibility requirements.
It is recommended to verify these on the official university website.
