As it cools, it becomes a liquid.1.3 evaporator, located inside the vehicle, the evaporator serves as the heat absorption component. The AC compressor is connected with the clutch, when it is not in use it will uncouple from the engine, but when it turns an load on the engine growths. This waste energy does nothing then effecting to the environment, which would be responsible for the global warming, and here by performing this experiment we are going to utilize that amount of the wasted energy, without effecting the efficiency of the engine.
Exhaust gas from the exhaust manifold is used to drive the turbocharger. Similarly for four stroke engine which require four stroke of essay about air conditioner piston or two complete revolutions of crankshaft to complete cycle is known as four stroke engine. Although the driver doesnât pay any extra money for the air conditioning but he, earn. It can be quite a punishment to travel in such a car. During the downward motion of the piston the mixture in the crankshaft is compressed, futher pushes into the cylinder through the transfer port, which pushes out the exhaust gasese through the exhaust port, and at the same time filling of the new charge. Exhaust gas passes through the filter trap. Basically, an air conditioner is like a refrigerator.
