Well, the definition of cold is the absence of heat. So I think the definition of refrigeration is the process of removing heat. Please let me know if this helped.

What would we replace when my double beer tapper is freezing in both the underneath box which in turn is making the lines freeze. Its 9 years old but in a residence and has air circulation. What shou


when a refrigeration system shows signs of freezing, it means that the low side pressures are falling below 32 deg f....typically a sign that you have lost some of your refrigerant gas. Check your pressures with appropriate gauges(determined by the specific refrigerant in your system) if low, add refrigerant until they reach optimal levels. If you have no test ports, call your appliance repairman, epa certified in hvac, for service.

if this is a gas absorption refrigerator make sure it's level while operating.
check for heat at the roof vent if no heat check heating element or, gas burner behind the refrigerator accessible through the refrigerator outside hatch; next: check the relay and, inverter it is located under the refrigerator front if all these things check ok and, especially if you find a yellow power on the gas refrigeration unit the tanks behind the refrigerator box; you must replace the gas refrigeration unit by: removing the refrigerator from the cabinet from the front then lay it down and remove the gas refrigeration unit replace it with a new one but, don't forget to remove the 3' long spiral metal strip from the old gas refrigeration unit exhaust vent and, reinstall it in the new gas refrigeration unit the gas refrigeration units can be purchased online.

I just got a used deep freeze.. but i was told something was wrong with the copper tubing.. it needs to be replaced.. what does this copper tube do? and relatively how much could it cost?


if the copper tube needs to be replaced then that means it is now worth fixing. the copper tube is what the refrigerant runs through. no copper tube - no refrigeration. Also you would have to fully destroy the fridge to get to the tube anyway. You may as well get rid of it. sorry

Cold Air is at a minimum Can it be recharged?


i am trying to undestand what you mean with minumum.in refrigeration minumum is very cold which would be a good thing.but i am assuming you mean your cold air is not cold enough.this small units generally don't have a charging valve,but if it does yes you can charge it more but not to much because your air is not going colder if it has too much freon.in thecase the unit does not have a valve you can install one but you need a torch to solder it and the use a vacuum pump to remove the air insede the tubing then you can charge the freon.also in the refrigeration stores they sell solderless valves which you can install but have to be very carefull that they don't leak after isntalled.hope you got all my expanation and it can be usefull foor you.

The compressor on my Sears Coldspot is running at 175 degrees.


Refrigeration compressors used in domestic refrigeration are known as high side compressors, meaning the dome is at high side pressure and temperature.

As long as the condenser fan was running, and the coil was as clean as you could get it, then all is OK. There is no standard temperature that it runs at, and it has been tested to run hot anyway. The fact that you cleaned underneath will allow it to run a little cooler anyway.

We have a stand alone freezer (Whirlpool) and just notices the sides of the freezer are very hot to the touch. Could that mean the coils are not working properly?


It is normal.That is a portion of a refrigeration system where high pressure gas condensed into a liquid by means of transfering heat to the surrounding air.
That portion is called CONDENSER COIL.
