The video module “Energy Saving and Efficient Energy Use of Energy in Air Conditioning Systems” is part of a series of 10 advanced e-learning lectures developed and published on the Vietnam Energy Efficiency Community platform. This module focuses on air conditioning systems – one of the largest electricity-consuming loads in commercial buildings, service facilities, and manufacturing plants.
The lecture is presented by Mr. Dương Chí Công, Chief Energy Auditor of VETS | EnE. With many years of experience in energy auditing and consulting on energy-saving solutions for businesses, the lecturer delivers a systematic approach that closely connects technical principles with real operational conditions.

The Lecture Provides Practical and Industry-Oriented Technical Knowledge
Through an approach that combines fundamental principles with practical applications, the lecture series “Energy Saving and Efficient Energy Use in Air Conditioning Systems” provides viewers with practical knowledge on:
- Selecting suitable and energy-efficient air conditioning equipment
- Identifying solutions to reduce cooling loads
- Important considerations during installation and maintenance to minimize energy losses
At the same time, the lecture introduces integrated solution groups to optimize operational costs, including:
- Selecting high-efficiency equipment
- Applying inverter technology
- Controlling external and internal heat sources within buildings
- Setting appropriate temperature and humidity levels according to climate conditions
Conducting periodic maintenance - Researching alternative solutions such as nighttime thermal energy storage or off-peak operation strategies
The lecture is designed with a clear and structured layout, incorporating refrigeration cycle diagrams, technical parameter analysis, and visual illustrations. It provides enterprises with training materials and technical knowledge to evaluate and optimize air conditioning systems, helping reduce electricity costs, improve operational efficiency, and move toward sustainable and efficient energy use goals.
