How a refrigerator works

Please improve this. I am trying to find out how a fridge works and this has confused me even more. For example 'saturated liquid refrigerant', what is it saturated with? Can we have some boiling points for the refrigerant and figures for the pressures please, so that we know the pressure of the superheated vapour, and the flash pressures? What about telling us where the parts are relative to each other, eg compressor, condenser, coils etc; a diagram would be helpful. 25 Oct 06

Commerical Freezers?

I read somewhere that there was a standard for a super-freezer, for food service use. Something that prevented bacteria growth in raw fish, etc. Regular consumer fridges reach like -30, but this was far colder (-60?) and used not only for Sushi stuff, but flash-freezing raw produce? Details are lacking, and I don't find it on this page, so I'm wondering if I saw it in a prior revision and I'm wondering if the deletionists got to the information (ie: does anyone have an application that will search the old versions of wikipedia articles?)

Refrigerator Reliability

Refrigerators in our days becoming more and more advanced, with a lot of sensors, control boards, interface boards, etc. Manufacturers are trying to make them be more Energy Efficient. But at the same time, reliability is got worse. You were able to troubleshoot and if needed replace the problematic mechanical thermostat on the old refrigerator. Today, everything relies on the control board and sensors. If the control board will fail, nothing going to work. To troubleshoot a complicated control board, you have to have some electrical skills and knowledge. Not as with a simple mechanical thermostat. Where a majority of DIY'ers were able to fix or replace refrigerator thermostats.

Auto-Defrosting

This info needs to be corrected because there are some misinformation provided in the text "Frost-free refrigerators, including some early frost free refrigerator/freezers that used a cold plate (this type of refrigerators with cold plate never had an auto-defrost feature) in their refrigerator section instead of airflow from the freezer section, generally don't shut off their refrigerator fans during defrosting (this is not true. compressor and fans need to be off in order to perform defrost cycle). This allows consumers to leave food in the main refrigerator compartment uncovered, and also helps keep vegetables moist. This method also helps reduce energy consumption, because the refrigerator is above freeze point and can pass the warmer-than-freezing air through the evaporator or cold plate to aid the defrosting cycle."
