Air conditioning system — general information [Toyota RAV4 XA10]

The air conditioning system cools and dehumidifies the air in the cabin. The refrigerant, circulating as a liquid in the high-pressure part of the system, evaporates and turns into a gas in the low-pressure section. When the gas expands, cooling occurs, accompanied by the removal of heat from the air supplied by the fan to the passenger compartment. Moisture from the air supplied to the cabin condenses on the evaporator. The air conditioning compressor, driven by a belt from the engine crankshaft, captures the gaseous refrigerant, compresses it and sends it to the condenser located next to the engine cooling radiator. As it passes through the condenser, the refrigerant changes into a liquid state, releasing the absorbed heat to the oncoming air flow. The liquid refrigerant then flows back into the evaporator through the metering valve, thus repeating the heat extraction cycle.
