water in phase change?

johnnyw · Apr 28, 2003

Does a phase change system need water? I mean a reservoir with water... could someone explain with graphics what has to be attached to what ( compressor to so and such and the function of the " " is such)

No a phase change system does not use water, it uses refrigerant. The temperatures they create are far below freezing.

Here is a good link my friend:

can´t I cool down water and make pass though the wb instead?

Ya you could make a phase change water chiller... some people just tear out the components from a fridge and submerge the cooling coils in a resevoir bucket basically. You might need some way to control the temperature of the water however depending on the strength of your compressor. And some people just put a heat exchanger inside of their fridge too I guess.

No reason to make your system a chiller over direct die phase change. Your temps will be much better with direct.

But MUCH harder to achieve for a beginner....

johnnyw .. I would recommend that you start with a chiller. Learn about phase change systems, insulation, etc etc.

Once you have this done, then start thing about a direct die system.

yes I would also recommend you stay with a chiller, its much easyer for not just a beginner, but for anyone

I agree with you guys... I´ll go for a chiller ( once I recover myself from surgery)

this will be my first phase change design. I am planning to make a water chiller finally . I´ve got an old compressor , what seems to be a radiator and another cylindrical tube which I suppose is the dehumifier. is the refrigernt turn into liquid supposed to be coming out of the dehumidifier?? How can I make this system to chill water instead of transporting liquid so cold.... i mean , where would the reservoir be placed??? How can I "tell" the compressor : "hey , the water is get hotter I´m not on idle".I would not like the compressor to run at 100 % 24/7. I know that this is regulated by a thermostat,but how is it???

how can I upload a picture to show my graphic?
