Toyota RAV4>> Cooling systems and conditioning>> General information>> Air conditioning system
Air conditioning system cools and drains air in salon. The coolant circulating in the form of liquid in that part of system where high pressure is supported evaporates and turns into gas on the site of low pressure. At expansion of gas there is a cooling which is followed by selection of heat from the air given by the fan to passenger salon. From the air given to salon on the evaporator moisture is condensed. Air conditioning system compressor given by a belt from a bent shaft of the engine takes gaseous coolant, squeezes it and sends to the condenser close to a radiator of cooling of the engine. During passing via the condenser coolant turns into liquid state, giving absorbed to warmly counter flow of air. Then liquid coolant via the dosing valve gets to the evaporator again, thus, the cycle of selection of heat is repeated.
