Principle of action of the conditioner

The conditioner compressor through клиновой a belt is resulted in rotation from a cranked shaft of the engine. He creates pressure to 30 bar in a contour of cooling of installation owing to what the coolant representing gas, heats up. In the condenser the coolant is cooled by air proceeding outside (cooling air remains in an environment). Thereof разогретый the coolant is condensed, turning to a liquid. Having the big pressure, it is passed through a throttle therefore its pressure falls. After that the coolant evaporates in a contour, simultaneously strongly being cooled. In the evaporator the coolant selects heat from air blown through it. Thereof air is cooled. Cooled air arrives in car salon. As a result of heating in the evaporator the coolant turns to gas and under low pressure arrives in the compressor.
