Could you expand on your answer, I understand the principles of refrigeration where in domestic/commercial appliances, the heat exchange is driven by an electrical pump which is a closed recycling system. I need to know more about effective and reliable refrigeration systems which can work in an enviromnent where there will be no electricity.

Do a search on "absorption cycle" refrigeration.
They work using heat alone and they have no moving parts. Quiet, reliable, and no electric pump is required. The refrigeration effect is obtained by exploiting a temperature-dependent solution concentration of two materials.
These are commonly used in mobile homes and in areas where an electric supply is not reliable.(or not available.)

There a re no mechanical moving parts in a gas powered refigerator. The most common cycle is the absobtion cycle. Usually called the Electrolux cycle. The chemical used is ammonia and water. With a gas pilot light provivding the heat source in order for the cycle to work.
One interesting point about the absorbtion cycle fridge is that if it fails to cool down properly. A simple fix is to turn the fridge upside down this seperates the chemicals out again and allows the cycle to work properly again.

a perfect gas would increase it's temperature if placed under pressure and vise versa
what happens is that a cooling system would use a gas apply pressure to it and then cool it by air so it would take the room temperature, then pump it into a different compartment where we want to cool things and release the pressure of the gas causing it to drop in temperature

The gas is pumped round under compression, and as you know when you compress a gas it turns into a liquid and freezes. The same system is used in reverse to produce heat.

the gas is compressed which causes it to heat up, and once this heat is dissipated, it is released and as the pressure drops, the temperature drops cooling the surroundings.
it could also be used to power the pump to do the compression...

Dont really know this one but I do know that you can or could get them and they ran from mains gas. Other than that I am lost. Why not get in touch with the gas people and ask them or a gas engineer.

THE BOTTLED GAS IS USED TO HEAT THE CHEMICALS IN THE FRIDGE,CUSING A REACTION...HENCE COLD
