PRINCIPLE OF REFRIGERATION

The principle on which cold is generated is demonstrated by a well-known phenomenon. When a few drops of a volatile liquid (e.g. alcohol or ether) are poured on to the hand they produce a sensation of cold. The explanation is that the liquid evaporates, extracting the heat required for vaporization from the hand, which is thus cooled.

Similarly, in a refrigerating machine a liquid refrigerant is made to boil (or evaporate) at a low temperature in a cooling element (evaporator). The heat required for vaporization is extracted from the surroundings, which are thus cooled down.

before, after, as soon as, because, although, so, when

1) Vapour is compressed. The cycle starts again.

2) The Carnot refrigeration cycle is the most efficient cycle. Every attempt should be made to
reproduce it with actual equipment.

3) The minicomputers are very small. They are capable to solve different problems.

4) The farther will do this for you. Ask him.

5) You'll find him. I want you to phone me.

6) I can't understand the speaker. He's speaking very quickly.
