Package description<br />
The heat<strong>in</strong>g control bench is used to study a central heat<strong>in</strong>g system with<br />
control loops.<br />
The operational part represents a reduced central heat<strong>in</strong>g system compris<strong>in</strong>g:<br />
@ a 3-way motorised valve<br />
@ a variable speed pump (circulator)<br />
@ a heat exchanger (fan-cooled heats<strong>in</strong>k).<br />
The control part <strong>in</strong>cludes a Premium PLC which provides all <strong>the</strong> control<br />
operations, an Altivar variable speed drive and all <strong>the</strong> associated electrical<br />
protection elements.<br />
A graphic operator <strong>in</strong>terface term<strong>in</strong>al is used to control and monitor <strong>the</strong> system.<br />
An E<strong>the</strong>rnet connection allows you to connect a computer and control<br />
supervision remotely.<br />
The system is configured to use one of <strong>the</strong> three follow<strong>in</strong>g control loops:<br />
@ PID loop: central heat<strong>in</strong>g with <strong>in</strong>ternal temperature sensor<br />
(act<strong>in</strong>g on <strong>the</strong> water flow)<br />
@ PID loop + servo: central heat<strong>in</strong>g with <strong>in</strong>ternal temperature sensor<br />
(act<strong>in</strong>g on <strong>the</strong> three-way valve)<br />
@ PID loop: central heat<strong>in</strong>g with external temperature sensor and water<br />
ratio (act<strong>in</strong>g on <strong>the</strong> three-way valve).<br />
The system can be disturbed us<strong>in</strong>g a set of three motorised fans of variable<br />
speed.<br />
