PDH UNITS: 6
There are almost endless variations and combinations of space heating systems, each having its strengths and limitations. There are two different but related values of interest to the heating system designer. First, providing comfort and secondly, to properly select and size the appropriate heating equipment. This requires estimating the annual energy requirements and then analyzing the operating dollar expenses on prevailing fuel costs. Note that the fuel price alone is not the sole measure for selecting a heating system. The broad comparisons on the choice of a heating system is based on various system characteristics such as equipment costs, equipment efficiency, fuel source availability, required system capacity, fuel energy content in millions Btu per unit, environmental impact and heat response or recovery. In this 6-hour course we will discuss about various active heating options and design consideration for the best fit strategy. In this course, we will categorize heating systems in several ways. First we will consider where the primary energy comes from. Then we will compare the various options and discuss the variety of ways used to deliver heat within the space and finally, some general guidelines on the energy conservation and application strategies for various buildings.
