Technology Features & Specifications
1. Artificial intelligence (AI) based hybrid physical/data-driven ventilation model to accurate calculate the minimal required air-flow/energy according to the timely comfort or CO2 index;
2. A three-level hierarchical control platform to realize the air-balancing with minimal energy loss and best control performance;
3. Reliable & accurate fault detection and diagnosis (FDD) strategy with proposed joint distribution adaption for a deep learning model.
As buildings account for 35-40% of total energy use in many countries, and in schools and hospitals the need for energy for building services is audited to be just above 50%, the research outcomes have significant economic potential. The developed on-line smart air balancing system can be applied into both VAV and DOA systems, and all of the existing air-balancing systems can be upgraded to the proposed air balancing system to realize timely air-balancing of the building with minimal energy consumption. Since the developed on-line smart air balancing system is a generic system, it can be applied into the building all around the world. Therefore, the potential for applications will be tremendous.
Market Trends and Opportunities
Singapore is a tropical country with annual average temperature of 27º and annual average relative humidity of 84%. The air-conditioning and mechanical ventilation (ACMV) systems consume about 60% of the total energy in a building, where approximately 60% of the total energy is consumed by treating ventilation air. The research outcomes have significant economic potential as the energy-saving for the building. According to conservative estimates, the proposed solution can bring up to 70% energy saving when used in ventilation system compared to the traditional air-balancing method in VAV systems. Therefore, the research will create a new economic opportunities for energy-saving.
The proposed method and the products address current challenges in VAV system and give a well solution of energy-saving for new building and existing VAV system. The project will give a large potential of energy-saving for the building. Benefits may include the energy-saving, the reduction of the amount of pollution created on-site of at the electricity generating plant, and the reduction of the noise of the ventilation system.
