Presentation Transcript

  1. Lecture Objectives: • Show an example of dual wheel system • Learn about desiccant systems

  2. Heat recovery system in NSM building at UT Enthalpy W Sensible W

  3. HW4 (Due March 23rd) 1) Using NMS’ AHU, show the process in the Psychrometric chart for Austin’s a) Fall humid day (Outdoor: T=24C & RH=90%) b) Fall dry day (Outdoor: T=24C & RH=50%) c) Winter (T=3C RH=70%) For fall: T hot deck is minimum 24C, T cold deck is 13C For winter: T hot deck is 35C, T cold deck is 13C For each case: (a,b, and c) calculate RH of supply air in hot and cold deck.

  4. Also HW Reading assignment • Desiccant systems • http://www.ce.utexas.edu/prof/Novoselac/classes/CE397b/Handouts/1-s2.0-S1364032109001737-main.pdf

  5. Desiccant wheel

  6. Figure 3 – A desiccant-based cooling system combined with regenerative heat exchanger, vapor compression cooling, and evaporative humidifier (hybrid system). Desiccant wheel

  7. Variation in Cycles Much more in the paper I gave you (Technical development of rotary desiccant dehumidification and air conditioning)
