Phase Change Basics
1. What is phase change?
Phasechange is a term used to describe what happens when refrigeration occurs. Lick your finger, and wave it around in the air. You are experiencing phase change. The spit on your finger evaporates as you wave it in the air, and as it evaporates, it sucks up heat along with it.
2. How does phase change work in a refrigeration system?
The compressor compresses the refrigerant into a high pressure... Where in the condenser, it condenses to a liquid under high pressure and also at the same time gives up its heat. It then travels to the liquid line, where liquid refrigerant usually travels through a filter/dryer, which filters out particles and is a desiccant, meaning it absorbs moisture. From that point, it travels to the metering device, usually either a capillary tube, or Thermal Expansion Valve (TXV). These regulate the flow of the liquid refrigerant, because at this point is under far too much pressure to evaporate. Once it leaves the metering device, it enters the evaporator, where the liquid refrigerant boils off, sucking up the heat with it. It then travels down the suction line of the system, back through the compressor, and into the condenser.
thanx to jimmydean a very good mate of mine for helping with this.......
EDIT: there will be more to come.....waiting for my mate to come up with the rest

well i doubt it is atm cos he is on air cooling
