    • High Performance in Low Flow Solar Domestic Hot Water Systems 

      Dayan, Myrna (University of Wisconsin-Madison, 1997)
      Low-flow solar hot water heating systems employ flow rates on the order of 1/5 to 1/10 of the conventional flow. Low-flow systems are of interest because the reduced flow rate allows smaller diameter tubing, which is ...
    • Parameter Estimation and the Use of Catalog Data with TRNSYS 

      Rabehl, Roger J. (University of Wisconsin-Madison, 1997)
      Due to assumptions, idealizations, and detailed specifications often required by existing TRNSYS components, difficulties are encountered in modeling the performance of cataloged components within TRNSYS transient thermal ...
    • Process Energy Efficiency Improvement in Wisconsin Cheese Plants 

      Zehr, Stephen (University of Wisconsin-Madison, 1997)
      Wisconsin continues to lead the nation in the production of cheese, providing about 30% of the national supply. The industry is less secure than it once was, however, due to narrowing profit margins and competition ...
    • Promising Freeze Protection Alternatives in Solar Domestic Hot Water Systems 

      Bradley, David E. (University of Wisconsin-Madison, 1997)
      Since the gains associated with solar thermal energy technologies are comparatively small in relation to the required capital investment, it is vital to maximize conversion efficiency. While providing the necessary ...
    • Simulation of Ground Coupled Vertical U-Tube Heat Exchangers 

      Rottmayer, Steven P. (University of Wisconsin-Madison, 1997)
      Ground coupled heat pumps are an efficient alternative to conventional methods of conditioning homes, because instead of using the ambient air they utilize the ground as an energy source or sink. However, ground coupled ...
