Description

Technical Field

[0001] This utility model relates to a controller system, specifically a controller system for regulating ambient temperature. Background Technology

[0002] In real life, to save costs, a fan is often installed between two adjacent rooms. During installation, the fan is mounted in the common wall between the two adjacent rooms, with its two air outlets facing each room. This design saves energy and increases airflow. This method is mainly used in computer rooms, especially those where the monitoring room and control room are separated. The monitoring room is usually staffed and equipped with air conditioning, while the control room typically houses the main unit, which generates a significant amount of heat. In summer, when temperatures are high, cool air from the monitoring room can be sent to the control room; in winter, hot air from the control room can be sent to the monitoring room. This method is also widely used in housing and other fields. However, current technology requires manual timed switching of the fan, which is not intelligent enough. Especially when the ambient temperature reaches a preset high-temperature threshold, the fan cannot automatically operate to cool down. Therefore, we have designed a controller system for regulating ambient temperature. This controller system automatically controls the fan's operation, achieving automatic and intelligent operation.
