Abstract

The invention discloses an air conditioner control circuit of a truck system. The circuit comprises a steering switch, a first rheostat, a first capacitor, a first NAND gate, a first triode, a third relay, a switch, a second NAND gate, a first NOT gate, a third NAND gate, a second NOT gate, a second relay, a second triode, a first pulse motor, a second pulse motor, a third triode, a second rheostat, a third rheostat and a voltage comparator. The first NAND gate is connected with the steering switch, the first capacitor, the third relay and the first triode; the second NAND gate is connected with the third NAND gate, the second relay, the first NOT gate and a rotating speed signal; the first NOT gate is connected with the second triode; the third NAND gate is connected with the second NOT gate and a set rotating speed signal; the second NOT gate is connected with the third triode; and the voltage comparator is connected with the second rheostat and the third rheostat. The air conditioner control circuit of the truck system can cut off the air conditioner system when the rotating speed of the engine is too low, and the load of the engine is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an air conditioner control circuit for a truck system. Background technique [0002] In the current automotive air-conditioning system, when the power switch is turned on, the windshield switch, and the AC switch (Air condition) for turning on the air-conditioning compressor are turned on, the condenser fan and compressor will work, and the refrigerant (R134a) will flow through the refrigerant cycle of the evaporation core in the air box , the low-temperature liquid refrigerant formed by the compressor, condenser, throttle tube, etc. absorbs the heat of the surrounding air to achieve refrigeration. [0003] Such automobile air-conditioning system has the following defects. When the engine speed is too low, the air-conditioning operation increases the engine load, resulting in insufficient engine output power, thereby causing the engine flameout problem. [00...
