Bingly, the reason the thing shut off is because the compressor in it is thermally protected.. it over heated.. if you put a fan on it.. it won't shut off.

Condensation on the lines? Man.. You gotta insulate!

Took how long to go down to that temp?
My current 1/20HP compressor can drop water from 80F to 20F in no time.. That's with the water sitting still .. heh..

Either way the systems that we are designing are ment to be run.. 24/7.. they are insulated.. and quiet.. Atleast mine is quiet..

If you want to take it a step further.. You can install an accumulator.. or a sub-cooler.. or an accumulator & sub-cooler combo.. that would really up your efficiency and performence.

For ANYONE here thinking of building a water chiller.. If you are using an under-rated compressor you are going to need a large amount of freon to deal with the heat load.. even for those of us who use a good HP compressor.. you are still going to need to use a large amount of freon in the system.. Once the freon goes into the evaporator.. chills the water.. IF there isn't enough heatload on the evaporator and liquid freon (cold) comes out of the evaporator and goes into the compressor.. that's called liquid slugging.. YOU DO NOT WANT THAT! It can really damage your compressor and it also kills the efficency.. making it work harder.. Sure your compressor will stay pretty damn cool.. At one point my compressor was below ambient.. heh.. But it's not good..

You might be able to just have a segment of your return suction line going straight up.. this might stop most of the liquid freon from going back up and into the compressor... Or you could just install more evaporator.. Having the "2nd" evaporator wrap around some of the condensor tubing.. You just need to do something to warm the liquid freon back up to a vapor point.. IN a regular refrigeration system this isn't a problem because they only have enough charge in them to handle the heatload.. So by the time the freon comes back around it's vapor.. In an AC system though.. you must have a large freon charge.. because of the high heatload that it takes.. They have accumulators on AC units..

Basically an accumulator just takes the liquid freon in.. lets it warm up to get sucked out as a vapor then..

I personally use the extra liquid freon to cool my condensor.. It lets me run the condensor fan at a slower speed and gives me better efficency over all..
