THE HOT & COOL OF THERMAL SCIENCE AND ENGINEERING

OCTOBER 17TH 2016

VINOD NARAYANAN PROFESSOR, DEPARTMENT OF MECHANICAL AND AEROSPACE ENGINEERING

MECHANICAL & AEROSPACE ENG

Outline

Thermal science and engineering – energy, water,

efficiency

• Building energy

• Renewable energy generation- solar

• Desalination

• Fun!

MECHANICAL & AEROSPACE ENG

1 quad BTUs = 1.055 x 1015 kJ (5 times the energy of the most powerful nuclear bomb tested) 8

ROLE OF THERMAL ENGINEERING IN BUILDING ENERGY EFFICIENCY

MECHANICAL & AEROSPACE ENG

Building HVAC

• Norm: Vapor Compression refrigeration

• Near term solutions • High efficiency HVAC • Indirect evaporative cooling • Hybrid VC+ indirect systems

Longer-term solutions • Absorption & adsorption refrigeration • Solar cooling

Use less HVAC • Reduction in HVAC load by building

insulation • Reduction in leaks in ducts/buildings

MECHANICAL & AEROSPACE ENG Reduction in HVAC load by building envelope sealing
