有没有办法在配电箱可以测一个switch 的耗电量?

measure the current, estimate the compressor duty cycle, then you can
calculate the average power

这个是不是只能测实时电流?因为冰箱并不是一直工作的。
要是可以测一段时间的电流变化并给出平均电流就最好了。
接上一天后,平均电流,乘以110,就可以算出实际瓦数了。

subzero is supposed to consume very little power. many new models is below
100W.
my 24 yr old subzero (501R) has a label next to the door hinge, on the upper
side. It shows the model, manufacture date, operating voltage (115V) and
current (3.0 amp). If these are AC voltage and currents, then the average
power is supposed to be 115*3/2=172 Watt.

it has two compressors. on average, a subzero fridge lasts for 20 years, in
colder places, over 20 years.
it also consumes little power, but can keep food fresh longer. when my
mother came to my place, she said my fridge keeps food at least twice as
long than her fridge at home.
but on top of all, subzero is for built-in kitchens as oppose to the common
free-standing fridges. it is meant to be integrated with the cabinet and the
counters, with a uniform styling. you have many options for the door panels
, so it can look exactly the same as your cabinets.

well, at least that's what my mother said, and that's what subz advertised.
I do feel it can keep food fresh longer, but not clear by how much. Also, my
subzero is an all-fridge (no freezer), and I have a separate deep freezer
in the basement. I think this also helps a lot in keeping food fresh and
cutting energy loss because there is no compromises for both components and
food contamination.
after being used day to day for such a long time, the inside still looks
like new. the material is so durable, and well designed. it has a lot of
space, we really enjoy it.

sorry, I think both voltage and current are RMS values already, so no need
to divide by 2. the average power should be 345 W.
this probably is the continuous power consumption, you may need to multiply
the compressors duty cycle (portion of time that is on). for example, if the
fridge turns on 3 min every 10 min, then the power should be ~100W.

g***r 发帖数: 281 | 18 我问查耗电量,楼咋就垒歪了?我这冰箱也有20年了。
担心密封不好,要是冰箱一直run着,耗电少不了。
所以想找个简单的办法测一下平均耗电量。

you should multiply this with duty cycle.
someone measured a subz 550 with a meter, it consumes 150W for the fridge-
only with a duty-cycle of 30/80=37.5%.
http://appliantology.org/topic/41187-subzero-550-energy-consump
the meter costs $200

耗电和使用习惯应该也有关系,比如,你冰用得多,那个制冰机老是工作,耗电量肯定
就大了。。。
