Fairly new Coca Cola refrigeration unit @ restaurant. Compressor was cleaned of dust last night. Compressor worked this morning until late afternoon, then stopped working aprox. 6pm tonight. Compressor making clicking noises, but failes to turn on. Have shut off the Coca Cola Refrigeration unit. Other then calling in a repair, what can be done? Question: what is the cause of this problem?

I drive a truck. I need one of those LARGE coolers, (like the big ones you need two people to carry, or the ones with wheels and a handle), with the refrigerator units that plug in to the cigarette adapter.

I'm doing a project for an intro engineering class which uses an alternative type of coolant in a refrigerating system. I've looked into the basics, and the idea seems simple enough, I need a compressor, expansion valve, and pipes, basically.

I know that once you OPEN a bottle of many different types of drinks, it has to be refrigerated, but what if you haven't opened it up yet? I just got a huuuuge amount of V8's, Odwallas, and Fuzes for free. I have plenty of shelf space to store it, but I don't have a fridge. Can these be kept on the shelf or do I have to put them in a fridge??? And keep in mind I probably have enough to last me through the summer too, at least Thank you!

the compressor heats up the cooled liquid (which has gotten warmer already by absorbing heat) into a hot pressurized gas. with the release of pressure by going through the expansion valve the gas is cooled abruptly from the change in pressure, so why do all diagrams for it show coils dissipating the heat before reaching the expansion valve? is it really necessary? won't it cool to the same temperature after the change from very high to very low pressure?
in response to the car AC analogy, how can heat be dissipated (lost to environment) while keeping the pressure the same? according to the ideal gas law: PV = nRT
pressure is inversely proportional to temperature, therefore, a decrease in temperature should net an increase in pressure….AH! there's the answer, you're absolutely right, by increasing pressure, it will allow an even larger pressure reduction at the expansion valve making it easier for the gas to be forced through. thank you so much for the help, it makes much more sense now. but now i have to ask, does my reasoning even make sense or did i miss something else?
Desert Tripper, just to get things straight. after the gas goes thru the Expansion Valve, it is turned to liquid, and as it absorbs heat it is slowly returning back to a gas as it reaches the compressor, which is the reason it is able to be compressed (cuz it's a gas now). so now it's under very high pressure as a hot gas, the heat is dissipated by going through the condenser coil, which brings the temperature down to switch it back to a liquid. it passes through the expansion valve where the pressure is greatly reduced forcing a higher boiling point, which forces all/most of the gas into a liquid so it can absorb heat again. but i think i'm still missing something, why does it need to be partially turned into liquid before hitting the expansion valve by going through the condenser coil when the real phase change occurs due to the change in pressure at the expansion valve?

* aside from the use of solar panel, can it be possible to have another way of acquiring energy from the sun which will be used to power the refrigerator, which is approx. 163W?
* is there a cheaper alternative to the solar panel enough to power a 163W refrigerator?

I am considering enrolling in a local techinical college in order to get certified in this field of work. I am currently a student at NKU, but I feel like I need a better job (now) in order to keep going to the University (right now I work as a cashier and am getting a little tired of trying to get through a 4yr academic program on minimum wage…); who can give me some feedback on this line of work?
~ Thanks!
Okay…but none of you actually answered the question? … I am curious about THAT career
I have a student loan. I am on a waiting list for a Dental Hygiene program as well — the English degree I'm after is just for me. I'm just looking for something temporary
