| ABSTRACT |
The SSVPG is used in many places that require smoke ventilation or even to reduce the room temperature as many conventional ventilation system (CVS) do. The difference is SSVPG works automatically by the usage of sensors that detects the smoke/temperature. It automatically spins the exhaust fan and mechanically rotating the AC generator which is coupled together with the exhaust fan and then charges the battery. The innovation of this product is, it does not rely on the utility supply as it is also hook up with a solar panel which also charges the battery, Secondly, it generates energy as the exhaust fan mechanically rotates. Thirdly, an energy loop back feature is introduced to this system which will supply for the ventilator fan. Another major innovation is towards interfacing this device with an in house production of generator. This generator is produced by proper design on stator as well as rotor to reduce the losses. A comparison is made between the SSVPG and the CVS and result shows that the SSVPG saves 172.8kWh/year of utility supply which is used by CVS. This amount of energy can save RM 3.14 from monthly utility bill and a total of RM 37.67 per year. In fact this product can generate 175 Watt of power from generator(75W) and solar panel(100W) that can be used either to supply other household appliances and/or to loop back to supply the fans motor. The innovation of this system is essential for future production of other equipment by using the loopback power method and turning most equipment into a standalone system.
