Description
Technical field
The utility model relates to the automobile fuel-economizing device technical field, belongs to a kind of air conditioning for automobiles petrol economizer.
Background technology
At present, air conditioning for automobiles drives air-conditioning compressor work by driving engine when opening, because the air-conditioning compressor continuous working causes the automotive engine oil consumption to increase.And in actual use, when needs reduce vehicle interior temperature, generally can only reduce the air output of fan, and still work as usual of air-conditioning compressor makes the oil consumption of driving engine significantly rise.
Summary of the invention
The purpose of this utility model provides a kind of air conditioning for automobiles petrol economizer, it is by the clutch of multi-vibrator control air-conditioning compressor magnetic clutch, control compressor operating and the time scale that stops by the mode that changes pulse duty factor, make compressor intermittent use under the control of petrol economizer, quit work the stage at compressor, that utilizes a/c system surplus coldly continues to send cold wind, and oil-saving effect is remarkable.
For achieving the above object, the utility model is taked following design plan:
A kind of air conditioning for automobiles petrol economizer, it is characterized in that: it comprises ulf multivibrator circuit, pulse signal amplification circuit and relay, the mouth of described ulf multivibrator circuit is connected with the input end of pulse signal amplification circuit, the mouth of described pulse signal amplification circuit is connected with relay, and the normally closed contact of this relay and the magnetic clutch on the air-conditioning compressor are connected in series.
Described ulf multi-vibrator is to be made of IC, resistance R 1, R2, capacitor C 1, diode D1 and potential device W, wherein R1, R2, C1, and W be connected in series, the center-side of D1 and R2 and W is connected in parallel, IC is connected with the center-side of W, regulator potentiometer W changes the empty accounting of impulse singla, thereby changes the ratio of the interval work-hours of compressor.
Described impulse singla shows amplifying circuit and is made up of R4, T2, and resistance R 4 is connected with the input end of aerotron T2, and mouth and the relay J of aerotron T2 are connected in series.
This air conditioning for automobiles petrol economizer also comprises display circuit, the mouth of described ulf multivibrator circuit is connected with the input end of display circuit, described display circuit is made up of R3, T1, LED1, resistance R 3 is connected with the input end of aerotron T1, and the mouth of aerotron T1 is connected with compressor operating indicator lamp LED1.
IC, R1, R2, C1, D1, W constitute the ulf multi-vibrator, pulse duty factor is regulated by potential device W, impulse singla amplifies the rear drive relay J through T2, normally closed contact K in the relay is in wire harness is serially connected with electromagnetic clutch control circuit on the air-conditioning compressor, and the energising of magnetic clutch and outage are subjected to the control of relay normally closed contact.When multi-vibrator output active potential, relay outage, normally closed can the connection by point, the magnetic clutch adhesive on the air-conditioning compressor, the rotation of automotive engine Driven Compressor.When multi-vibrator output high potential, the relay adhesive, normally closed contact disconnects, and quits work because of magnetic clutch separates on the air-conditioning compressor.Blowing engine in the a/c system is not subjected to the control of air-conditioning petrol economizer, is in ventilation state always.After compressor changes halted state over to owing to mode of operation, the low temperature of the evaporator in the a/c system will continue for some time, and during this period of time, under the surplus cold effect of evaporator, the air-flow that blowing engine is sent will keep low temperature.After compressor stops operating, the temperature of evaporator will slowly rise, and when reaching specified time, the jump in potential of multi-vibrator output signal is to low level, and relay cuts off the power supply, and normally closed contact is closed again.Because the magnetic clutch adhesive, the power of driving engine is transferred to compressor through clutching force, and it is rotated again, and compressor enters mode of operation again, makes a/c system begin the process of the heat exchange refrigeration of a new round.Under the control of air-conditioning economizer circuit, compressor is in the intermittent use state that goes round and begins again, when compressor is not worked, surplus cold being fully utilized of a/c system, make blowing engine continue to send cold wind, and the intermittent duty of compressor has periodically alleviated the load of driving engine, and engine consumption is obviously reduced.
Advantage of the present utility model: circuit is simple, easy to use, air-conditioning compressor intermittent use under the control of petrol economizer, quits work the stage at compressor, and that utilizes a/c system surplus coldly continues to send cold wind, and oil-saving effect is remarkable.
