1.Initial power consumption
Large amount of electricity used at startup is called Initial power consumption.
Depending on the amount of the initial power, the total power consumption may be less than it is to turn off frequently.
Thus, we experimented to find the home appliances with large amount of initial power consumption.
2.Household appliances with large power consumption
We found which household appliances should be reduced use in order to reduce power consumption from our measurement.
You can save power efficiently with these results.
3.Illuminance
We found efficiently method to use lighting equipment such as difference between required illuminance and actual illuminance from measurement of the illuminance on the desk of the study.
Adjusting the light according to the required illuminance in order to save energy may be healthy because wastefully bright is non.
4.Temperature
We identified objects with lot of heat from measurement of the temperature of indoor objects to use air conditioner efficiently.
Reducing waste heat make us save energy.
The natural enemy of the air conditioner is heat.
It leads to saving on electricity purely to reduce fever.
Connecting between wiring of home appliance outlet and consumer electronics outlet.
We can measure...
Time of using electric equipment
Instantaneous of electric energy
Cumulative of electric energy etc.
Temperature measurement, by the amount of infrared energy
Range of temperature measurement is -40 to 510 °C
Measure the amount of light flux per unit area of the surface of the irradiated object.
measurement range 0.0~99.9/999/9,990/99,900/999,000 lx
[Measurement of power consumption transition]
1.We integrated electric energy [J] from the numerical value which we had recorded electric power displaying on the Watt Monitor at Continual intervals.
2.We found the timing which you should turn off your consumer electronics where you can use them effectively, by comparing electric power during initial operation and one during prolonging operation.
3.We found that air conditioner is influenced by initial electric power significantly in the course of the experiment, so we measured a plurality of the time changes in the outside air temperature and the room temperature, and calculated specially.
[Measurement of illuminance]
1.We measured the illuminance on the desk on the situation where we use desk light or ceiling lighting with digital luminometer.
2.We found the most efficient way to obtain the necessary illuminance by comparing the measured illuminance and JIS Z 9110-2010.
[Measurement of temperature]
1.We measured the temperature of surface the consumer electronics with radiation thermometer.
2.From measurement result, we identified the consumer electronics which have a great influence on rising room temperature and examined ways to use air conditioners effectively.
To compare how long should be the home electronics kept on, we made this calculus equation.
(Integrated usage power at initial operation -
Power consumption per second during stable operation × initial operation time) ÷ power consumption per second during stable operation
We named this Boundary of ECO".
Plug in the time and watt and you can calculate how long we should keep the home electronics on.
This is the average value we laid off.
The value of Boundary of ECO smaller than 60 seconds are showed 0.
