How do i take the heat form my campfire to cool my ice box? This is related to THermodynamics.?

Answer 1

This question is to do with entropy.

The thermal energy in the camp fire will be diffusing away constantly as the fire tries to equalise its temperature with the surroundings. Similarly, the cool box will be trying to warm up to equalise its temperature with the surroundings. As you well know, we can extract heat from the inside of a fridge and depost it outside the fridge even though it is warmer outside than inside. This is because we use what is called a 'heat pump'. We are using energy to move the heat from the cold area to the warm area.

I suppose you could use the fire to heat some water to make steam to drive a turbine to generate electricity to power a pump to extract the heat.

Answer 2

There are two common refrigeration systems that use heat as the energy source. One is an ammonia absorption refrigeration system and the other is a lithium bromide refrigeration system. Check out the links below.

Answer 3

You need the following: Ammonia water solution; hydrogen gas; sealed coil ; evaporator; a condenser; regulated flame from your camp fire. Then hook up as a propane or gas refrigerator.It would be easier to buy a small gas frig. rather than all this hassle!

Answer 4

You cant. There are some applicances that used heat to cool but forget it. Its to complex for a camp fire.
