usually the refrigerant you have pumped out of the system is contaminated (either liquid/air) contaminated refrigerant is less efficiant and will lead to a short system life. refrigerant is works kind of like the rain in a water cycle. The system starts at the compresser (the heart of the system) pushing refrigerant in to the condenser (like condensation in the clouds) condensing to a liquid and heads toward the metering device (raining) The metering devise rapidly lowers the pressure of the system into the evaporator (get the picture already?) where the refrigerant collects the heat in the refrigerated space and boils into a vapour releasing it to out side the refrigerated space. obviously there is more detail then this but thats the basic operation.

the boiling point of refrigerant in a refrigeration or air conditioning system determines the pressure of the low side of the system

The Evaporator is the part of a refrigeration system that absorbs heat. Its counterpart is the condenser which is used to remove heat that was absorbed in the evaporator.

You should not have to recharge your system unless you have a leak. Other wise you do not need to recharge your system.
You need a vacuum pump, gauges and freon. Take it to someone who does this work. A refrigeration guy can do it.

I need a diagram to show me where the canister is to recharge the air conditiong
The amount of Freon you will need to recharge your air conditioning system is dependent upon how low the Freon level is. You should begin with a one pound bottle of Freon.
You will definitely need to recharge your air conditioning system when it stops blowing cool air. You should recharge the system at least once a year.

An evaporator in a refrigeration system works by passing warm air over it's coils.
The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.
The easiest way to recharge your air conditioning system is with a recharge kit. The recharge kit will come with one pound of Freon, a gauge to tell you when the system is full, and instructions.
