Actual Appliance Consumption
 

Hi fellas, since I do not have access to those killawatts..i'd like to get your feedback on some things.

My fridge has a rated input of 100W

so is that 100W the maximum?

also, if I turn down the setting to 1 instead of the normal at 4, would it consume less power? Would setting it to 1 make it run at a lower wattage longer than at 4 where it will run at a higher wattage at a shorter time? which would be more cost effective?

Same goes for my airconditioner

just checked online..kill-a-watts are for 100-110volts..the current here is 220 volts...

Model numbers would help here.

Generally speaking, both units you mentioned run the same way. When they begin to operate, they draw enormous power to kick-start their compressors, then fall quickly to a fairly constant power draw. They cool the air until a thermostat is satisfied. The compressor then shuts off and the unit draws near zero power, waiting for another call to action.

Newer models have lots of energy saving doodads and custom controls built into them. They use less power to do the same thing as their predecessors did.

Regardless of the age or efficiency of the unit, changing the setpoint to a higher temperature will always make the unit run less. This in itself will save energy. If the unit is not actively cooling, it is not using much power.

You can get actual Kill-a-watt brand meters in 220 VAC flavor. I cannot remember the actual model number, but I found an equivalent knock-off on ebay quickly:

Exalta, if you set the thermostat to 1 instead of 4, then the fridge will still need 100W max (most of the time it is less), but it will turn on less often, so in the long run will consume less energy.

You may be able to find power consumption meters locally, they do not have to be branded "Kill-a-watt". Ask around at stores with electronic doodads. Good luck!

Hi there, thanks so much for the replies. I had a "Oooh so that's how it goes" moment :thumbup:

The refrigerator is an LG GC-269VL

and the airconditioner is a 0.75hp Carrier..i forgot the exact model..

I'll go have a look-see on the locally distributed knockoffs and see if they're affordable..well they'll be most probably made in China so they will be cheap...reliability and accuracy is still a question though

i checked the meter..i am running at .189-190 kW...then when i turned on the fridge (which had a input rating of 100w in the label) it suddenly jumped to .300-.301 kW..so thats 110w which is wayy above the one on the label...

You have to wait a bit for everything to stabilize.
