Task 4: Advanced HVAC Systems
Task 4 Fact Sheet
Currently, the cooling and dehumidification needs of India’s new commercial or multi-family buildings are served with building-by-building approaches using primarily mini-split and multi-split units or central chilled water, which may be distributed in a variety of ways. For both approaches, separate dedicated outdoor air systems (DOAS) to pre-condition fresh outdoor air and distribute it throughout the building would be recommended when energy efficiency and indoor air quality are both desired. In practice, in India, fresh air supply is often neglected and there is no DOAS, especially when unitary splits are used. Although the rapid pace of urbanization may create opportunities for central district cooling plants or cooling and power generation plants, which offer energy saving potential. The tolerance of a broader comfort envelope and on-demand space conditioning in India may create opportunities for non-compressor approaches (multi-stage evaporative cooling) in HVAC and/or DOAS applications.
The research purpose of this task is to develop and test energy efficient HVAC systems. The objectives are to re-optimize existing cooling and dehumidification system approaches for India’s commercial/multi-family new construction market; to target, develop, and test advancements to the state-of-the-art of physical system HVAC technology, both compressor-based or non-compressor based, that can significantly reduce cooling and dehumidification energy use in both India and U.S.
- Design of energy efficient and cost effective dedicated outdoor air system (DOAS) and micro-channel heat exchanger (MCHX) evaporator offering superior performance when integrated with small unitary systems
- Development of design and operation guidelines for radiant cooling system for both the countries
- Create state-of-the -art HVAC test facility in India
