The length andthe inner diameter of the capillarytube are determined according tothe capacity of the refrigeraonsystem, operang condions, andthe amount of refrigerant. The highpressure, high temperature liquid re-frigerant sent from the condenser expands rapidly as the refrigerant is sprayedout through the fixed orifice in the capillary tube. As a result, the temperatureand state of the refrigerant becomes low and mist-like, and therefore evaporateseasily.EvaporatorThe evaporator is a heat exchanger covered withslit fins. Heat is removed from the air being pulledacross the evaporator by the centrifugal fan.The resulng cool air is expelled through the coolingair ducts.AccumulatorThe accumulator is mounted on the sucon gas pip-ing between the evaporator and the compressor.The accumulator separates the liquid refrigerantfrom the gas refrigerant, allowing only the gas refrig-erant to enter the compressor. In the accumulator,sucon gas isled into a cylindrical vessel where thespeed of the gas is decreased.This process separates the refrigerant contained inthe gas by the force of gravity, causing the refrigerant to accumulate at the bot-tom of the vessel. As a result, the compressor is protected from possible damagecaused by liquid refrigerant intake.High Temp./High PressureLiquid RefrigerantLow Temp./Low PressureGas and Liquid MixtureFrom EvaporatorTo Compressor
