Boilers are vital for providing heat and hot water in the hotel industry. However, the<br/>extraction fan component of the boiler system has a flaw that its fan motor runs<br/>continuously, leading to overheating and frequent replacements. This issue affects the<br/>maintenance team, causing them to inhale harmful gases produced by the overloaded<br/>motor. To address this problem, a prototype was developed which includes a safety device<br/>for the extraction fan controller, an electrical interlocking relay, an overload protection<br/>relay, an emergency shutdown button, a selector switch with auto/off/manual modes, a<br/>counter timer for monitoring motor usage, a carbon monoxide sensor with an alarm, an<br/>LCD screen for monitoring, and a loud buzzer. The prototype has been tested and<br/>automatically disengages the extraction fan when the water temperature exceeds the<br/>allowed limit. Likewise, its overload relay was also tested and adjusted to prevent motor<br/>overheating. The prototype received an excellent mean score of 4.74 from respondents<br/>composed of Asst. Director of Engineering, Duty Engineer, Engineering Supervisor, and<br/>Technicians on duty. These results indicate that the extraction fan motor now fulfills its<br/>purpose and has the potential to prevent overheating. |
