2.Advantages:


1) Heating speed: Induction cooking heats the bottom of the pot temperature up to 300 degrees in 15 seconds, faster than a gas stove, greatly saving cooking time, improving the speed of service.


2) Energy-saving and environmental protection: Induction cooking has no open flame, reduces the loss of heat transfer, so its thermal efficiency can reach higher than 92%. There are no emissions, no noise, creating a greatly improved the kitchen environment.


3) Easy to clean: The Induction cooker has no fuel residue or exhaust pollution, so pots, stoves are very easy to keep clean.


4) Increased safety: The Induction cooker unlike gas, does not leak, and does not produce open flames, creating a safe environment. It has multiple security measures, timeout power, over-current, overpressure, under voltage protection Improper use causes automatic shutdown. Also, the stove panel is not hot, there is no danger of burning a user.


5) Accurate temperature control: The Induction cooker cooking temperature can be precisely controlled, both energy-saving and ensuring consistency.

4. Conclusion


1) Economic

By changing the gas stove to the electromagnetic stove, according to the renovation cost of 200,000 yuan calculation, in about 2 years the customer could recover the full cost. After Five years the University would save about 392,000 yuan total.


2) Social Benefits:

Because the kitchen stove is energy saving and reduces emissions, the consumer directly reduces energy consumption. In five years the consumption of coal is reduced to about 314453.85kg, or 314.45 tons, which directly reduces carbon dioxide emissions 803.72 tons.
