The matching of a thermostat to any temperature control problem is a simple operation, by consideration of the following basic principles.
Cyclic temperature behavior of the process may be influenced by:
1 |
Location and characteristics of the heat source. |
2 |
Location of the thermostat. |
3 |
Heat characteristics of the controlled medium, and the shape of its container. |
Thus the primary considerations are the relative locations of the heat source and thermostat. Also, by locating the thermostat in a place where it will heat or cool rapidly, its anticipation characteristics can be used to advantage because the thermostat can operate before reaching set-point and thereby reduce the total variation of the system.
The essential factor to remember is that the thermostat can react only to the temperature changes to which the shell is subjected.
