When the temperature rises in the car, the resistance of RT falls, and then the potential of A drops. When the potential of A is lower than the potential of B, the outputs of N2 and N1 are both high level, and then V is on, and the normally open contact of K is switched on. Then the clutch of air conditioner is on, then the compressor works. The air conditioning system begin to refrigerates .As the temperature falls in the car, the resistance of RT rises, and then the potential of A rises. When the potential of A is higher than the potential of B, the outputs of N2 and N1 are both low level, and V cutoff .The normally open contact of K releases, then the clutch of air conditioner is off. The refrigeration system stops work.
