    maybe offtopic but a question about phase change

    i have a stock watercooler (used to dispense water) and everytime the thermostat turns the cooler off. the wholething shakes for a secound. and if i pick it up and stake it around i hear the same sound. its coming from the phasechange unit.

    maybe somethings loose?

    btw the sound isnt made when it turns on, only when turned off.

    Thats probably the compressor stopping.

    Dont shake it, if it is what i think it is you can throw the piston off the springs and then the compressor is done for. Be carefull.

    i wasnt shaking it, when i first unpacked it. and put it into place i could hear something rattling when it was moved.

    Well just be careful. And never turn the unit upside down, and avoid putting it on its side.

    hermetrically sealed compressors make the knocking sounds when moved around, and when they are shut off they shake and make a little noise. just what they do.

    the sound is the piston hitting the walls. How "normal" that is, is a matter of how hard it is hitting the side. A little bunp here and there wont do anything but you shake it hard, drop it, flip it, and you will be out of a compressor.

    The whole motor and piston assembly is suspended on springs inside the housing to minimise noise.

    When the compressor turns off, the motor slows down and the movement of the piston reaches the low resonant frequency of the cradle, at which point the assembly rocks side to side often gently knocking into the housing.

    It's not the piston hitting the walls, the piston is enclosed but like epion said if you do shake it violently you could b*gger it

    Ah, didnt realize it was the whole assembly with the motor. Either way you dont want to test you luck there.

    I think it was on phase-change.com ages ago someone dissassembled a piston type compressor, they had some realy good high res shots of the workings etc. Its worth looking for if youve got a bit of time to spare...
