firstly, i want to know that can the refrigerator compressor speed be adjusted? Because some people say it can not be adjusted and some people say it can be adjusted???

Where did this come from ??? 8O

what do u mean? u mean the refrigerator compressor? the brand of the compressor is DANFUSS, 240Vac, 132W.

Hmm - i meant refrigerator compressor question on a robotics board :).

Cant seem to see where you will be ussing it in robotics.

is the refrigerator robot. The refrigerator is the body of the robot.
So, can the refrigerator compressor speed be controlled?

in the danfoss u can control the speed a little bit by reducing voltage but if you want a large range of control go in for a variable capacity compressor.

also u might want to look into servo driven expansion valves

hi the_robo_guy, very happy to see u :) .
can i use the frequency inverter circuit to control the fridge compressor speed?

it might work, but as i said for true control get a variable capacity compressor.

LG makes some if i am not wrong.

Does anyone know how long can the refrigerator compressor run?
additionly, in the compressor data sheet, i can not find any information about compressor runtime.
So, how to determine the compressor runtime in this case?
