power consumption of freezer
Hello,
I have connected a household freezer up to a power meter (plugged this power meter into the mains and then the freezer into it). I have noticed that when I turn the freezer on (initial internal temperature is warm ambient temperature) the power meter reads about 120-150 W. Once it reaches steady "on/off" cycling (when the freezer is cold), the power meter reads about 100 W (during the cycle period when the compressor is on).
I am pretty sure it is a fixed speed compressor because it operates with an "on/off" cycle, so I cannot understand why the power consumption varies.
Does anyone have any ideas as to why?
Thanks
