Design topology of a sustainable remote-controlled fan regulator for developing countries

Based on the need to use remote devices against the traditional wall-mounted fan regulators to switch and control the speed of fans, this review paper conveys the fundamental theory that governs the operation of remote-controlled fan regulators. From state-of-the-art in the research, the basic steps in the design and construction of remote controlled fan regulator were presented. Upon implementation of the circuit using locally available materials, discussions based on its working principle, applications and cost breakdown of the work were provided. A number of research goals which guided the work were executed based on an experimental research design. Findings reveal that the factory installed speed regulation of a ceiling fan can be easily duplicated upon implementation of the remote control device, with a digital display unit incorporated for precise speed control. To maintain sustainable production of the remote-controlled fan regulator, it is recommended that there should be a reduction of the size and weight of the set-up for greater marketability by using a triac instead of an autotransformer in the set-up. Moreover, improving the capability for omnidirectional speed control as against the unidirectional control of existing schemes is another way. In all of these, the advantage for commercialization is greatly advanced.
