Said electronic switch is connected to form by silicon symmetrical switch Q1 and capacitor C 5.
Said optocoupler ghyristor circuit is connected to form by IC1, R7, R3.
AC220V voltage is added on A, the B port, flow through sample resistance R1 and bidirectional triode thyristor Q1 powering load.
AC220V voltage is through power circuit simultaneously, and obtaining two-way voltage is the control circuit power supply.One road 6V voltage, as the control circuit WV, another road obtains+3.4V voltage, as the WV of infrared receiving circuit through R2 step-down, C4 filtering.
When static, infrared receiving terminal IC (3) pin is noble potential+3.4V.Be that the reverse input pin of voltage comparator ic 2a is 3.4V, and the in-phase end reference voltage is lower, IC2a exports electronegative potential.When static, the IC2b input pin also is an electronegative potential, and its end of oppisite phase V6 is about 0.16V, so IC2b output electronegative potential, optocoupler IC1 ends, and silicon controlled main rectifier BTA ends because of not triggering power supply, and socket Z must not be electric, and air-conditioning is in closed condition.
Remote-controlled start-up
Click opening on the air-conditioning remote control, crucial (being red color keys), a string infrared pulse signal takes place in telepilot.After infrared receiving terminal is received this infrared pulse signal, amplify through inner, after the demodulation shaping; Export a string undersuing, be added in the IC2a inverting input, through reverse back (voltage comparator is made phase inverter usefulness); From a string just the chanting of IC2a output terminal output towards signal; This positive pulse signal charges to electrochemical capacitor C7 through diode D8 and current-limiting resistance R6, makes IC2b positive input voltage constantly rise, when positive input voltage is higher than reverse input end voltage.IC2b exports noble potential, and LED is lighted, optocoupler controllable silicon IC1 conducting, and silicon controlled main rectifier Q1 obtains trigger current and conducting, and air-conditioning socket electrifying electricity makes air-conditioning be in holding state.
It is thus clear that for the first time by opening, key is actually start-up circuit.At this moment, click the ON/OFF key on the telepilot again, air-conditioning gets into normal operating condition, begins refrigeration.During the air-conditioning running, current ratio is bigger, and after diode D3, D4 pressure limiting, the pressure drop on resistance R 4 is about 0.7V (actual measurement 0.9V) in the interchange pressure drop that produces on the sample resistance R4, can reduce the rated power of sample resistance R4 like this.This pressure drop is added to the IC2b positive input after voltage multiplying rectifier and filtering, this voltage is greater than the reference voltage of end of oppisite phase.So IC2b keeps the output noble potential, continue conducting to keep optocoupler controllable silicon IC1 and silicon controlled main rectifier Q1, keep air-conditioning normally to move.The start-up course of Here it is air-conditioning.
When shutting down with remote, air-conditioning gets into holding state.The electric current that flow through on the resistance R 4 this moment is very little, and the electric current on the actual measurement R is very little, and the interchange pressure drop on the actual measurement R is 0.05V.This moment, diode D6 was anti-inclined to one side, and all electric charges on the capacitor C 6 were through resistance R 5 discharges, about about 1 minute; IC2b positive input voltage is reduced to and is lower than reverse input end,, IC2b exports electronegative potential; LED is by extinguishing, and the optocoupler controllable silicon turn-offs, and Q1 ends; Load power source is completely severed, and control circuit and air conditioner supply socket are in series and can use safely.
