Refrigeration 101

EVAPORATOR/RESERVOIR:

The next thing that will need to be decided on is a reservoir and evaporator. Now your evaporator should be about 12' of 1/4" copper tubing this should give it enough to get all of the Freon to boil off and give you space to hold a decent amount of extra Freon for heat load porpoises. Now you may want to make it longer depending on your system. If you are using a week compressor you will probably need to make it longer to increase heat load capacity but this will also raise the final temperature you can acquire slightly. Now if you have a high power compressor then you can keep it short because the Freon cycles at a faster rate. So now that you have chosen how long to make your evaporator you need to actually make it just coil it up and you’re done for now. At this point your evaporator is made now you need to decide on what kind of reservoir you want to go with. Many people just rely upon the expedience of phaze cooling to keep there reservoir cold all the time by having a high flow rate over the evaporative coil this yields pretty good results for systems optimized for high flow rate with a GOOD compressor to back it up. Now for those of us who like to have a buffer zone we want a larger reservoir as well as the people who have small compressors. As if your refrigerant doesn’t cycle super fast because you have a small compressor you don’t have a huge heat load capacity so you need to have a larger reservoir so that the water has more of a chance to cool before it gets recycled.

So in short here are some combos:

Long evaporator with large reservoir: For people with small compressors and for those of us who would rather have a buffer zone rather than the absolute lowest temperature long evaporator with small reservoir: For people who have a good compressor but want to use high flow rate but still have a bit of a buffer
short evaporator with large reservoir: for the people with a good compressor but wish to have a buffer zone
short evaporator with small reservoir: for people with a good compressors who desire a high flow rate system with now buffer for the fastest low temp possible as you can see how you decide to make your evaporator and how large your Reservoir is really all depends on your preference and also your components.
