Solution 1
-
The drying process in a Haier heat pump dryer is a closed-loop control system.
-
It is a closed-loop control because it has a sensor drying feature that adjusts the drying process to prevent over or under drying. This means the system receives feedback (the dryness of the clothes) and adjusts its output (the drying process) accordingly. This continuous adjustment based on feedback is characteristic of a closed-loop control system.
Solution 2
-
The drying process in a Haier heat pump dryer is a closed-loop control system.
-
It is a closed-loop control because the dryer uses sensor drying to prevent over or under drying. This means the dryer receives feedback about the dryness level of the clothes and adjusts its operation accordingly. This continuous adjustment based on feedback is characteristic of a closed-loop control system.
