E. Computerized Load
Analysis |
| |
|
|
| Purpose: A good
understanding of Load Design is necessary to fully appreciate
the practical aspects of HVAC systems. Very few engineers perform
extensive manual load designs, and yet no one should ask a computer
program to calculate something that they don't thoroughly understand. |

| |
|
3) Thermostat Equation |
| |
|
4) Part Load: Reheat |
| |

|
8) Other Considerations |
| |
|
|
| Purpose: The
primary knowledge that comes out of this seminar is a greatly
improved 'system' understanding. While very few engineers will
ever need to do complex psychrometric analysis by hand, it is
imperative that they understand psychrometrics well enough to
verify computer program results and even predict which systems
will perform better than others. |
