|
|
|
| Working principle |
| When the hot water supply switch is switched on, the hot running water will trigger on the electromagnetic valve, which activates the mirror defogger, while the mirror defogger is heating mirror surface the result will be a fog free mirror. Once the hot water supply switch is switched off, the hot water will stop flowing and will trigger off the electromagnetic valve, which in turn will deactivate the mirror defogger and mirror defogger will stop to work. |
|
| System advantage |
1, Auto-control circuit Mirror defogger switch is auto triggered on by the hot running water, and deactivated once the hot water switch is off.
2, Remarkable Energy Saving 90% energy is saved due to automatic control system, especially in hotels and resorts etc.
3, Easy installation, the water electromagnetic valve is with screw thread connection, easy to install.
4, Product is durable & reusable . Water switch is made of copper, which is durable, and can be re-used in the next innovation step to save building cost. |

| Energy consumption analysis |
| This analysis based on a fictional case: customers schedule of staying in hotel room is from 6:00pm to 6:00am. Customers usually turn on the vanity mirror light when in room; the common design of defogger circuit is sharing the defogger switch with vanity mirror lighting, this results in constant working of defogger for almost 12 hrs. When the new energy saving system is installed, the defogger is working for only 30 minutes, till the time, the customer takes shower. |

Conclusion of analysis |
Defogger without auto-control |
Parallel connected with lighting, if set a separated switch, defogger will be ignored to use |
Sharing switch with lighting |
12 hours |
Half of hour compares to 12 hours, energy saved 95.84%
|
BAGEN energy saving demister system |
Defogger circuit is separated with lighting, do not control by light but by hot water |
Sharing switch with hot water |
0.5 of hour |
|
| Remarks: In summer, if customer takes cold water for shower, In common designs, defogger works even there is no fog over mirror, but this won’t happen with this new energy saving defogger system. |
