How do you keep food cold without fridge?
put it in a Coleman
Eskimos use fridges for the same reason others use them - to keep food cold. They heat the inside of their homes as we do and a fridge keeps the food cold. Fridges do NOT stop food freezing. they remove heat from the items within them and radiate that heat outside the fridge using the radiator at the back. they only remove heat, to stop something freezing you would have to introduce heat.
Depends on how long has the power been off, you should check the contents of the fridge as soon as the power is back on. If the food (solids or liquids ) are room temp. I personally will clean my fridge and trash the content. But if the stuff still cold as always, I'll keep it and consume it normally.
simply to keep food fresh. If the fridge's temp is too high, food will warm to room temperature and go off faster. Too cold, then the food will freeze! Everytime you open the fridge door you are letting room temperature air inside, increasing the temperature of the air inside the fridge, therefore the fridge (if automatic) will measure the temperature and make the air to the right temperature.
it compresses air in the pipe's behind the fridge and places it into chamber, to keep it cold it takes air from within the fridge and re-compresses it.A refrigerator will keep food cold by converting gas into liquid, then liquid into vapour. Basic physics maintains that when two surfaces come in contact with the other, the surface with the higher temperature will cool to equal the temperature of its alternate. Coils and metal parts inside…
Placing hot food inside a fridge means that the motor has to start up and keep running until the temperature returns to normal. Also, food close to the hot food may become semi-warmed, which is not good for preventing food poisoning. Always rapidly cool hot food (cover and place in a draught on the window sill, for instance), and put into the fridge once cold.
