Fig. 1 is do-part structural representation of the present invention.
Fig. 2 is control section structural representation of the present invention.
Embodiment
Shown in Fig. 1, Fig. 2, relate to a kind of crankshaft connecting rod type varying duty compressor for air-conditioning system, comprise do-part and control section;
According to Fig. 1, described do-part comprises cylinder body 1, is arranged at the cylinder head 6 on cylinder body 1 top; Be provided with suction valve chip 5 between the side of described cylinder body 1 and described cylinder head 6, between opposite side and described cylinder head 6, be provided with exhaust valve plate 11; Described cylinder head 6 is provided with the intakeport corresponding with described suction valve chip 5, and the relief opening corresponding with described exhaust valve plate 11;
Varying duty compressor of the present invention also comprises: be arranged at the piston 4 in described cylinder body 1; Be provided with connecting rod 3 and crank 2 between described piston 4 and described cylinder body 1, and form slidercrank mechanism;
Wherein, the air intake passage of described intakeport side is provided with suction side Controlling solenoid valve 7, the exhaust passage of described relief opening side is provided with exhaust side Controlling solenoid valve 10.
Known in Fig. 2, described control section comprises storage battery 21, and its output terminal is connected with one end of ignition switch 22, and the other end of described ignition switch 22 is connected with conditioning control unit respectively by automatic control switch 23 and energy-saving control switch 24;
First signals collecting end of described conditioning control unit is connected with sunlight strength sensor 25, secondary signal collection terminal is connected with indoor temperature transmitter 26,3rd signals collecting end is connected with environment temperature sensor 27,4th signals collecting end is connected with evaporator temperature sensor 28,5th signals collecting end is connected with setting temperature sensor 29, and the 6th signals collecting end is connected with cylinder pressure sensors 30; First control output end of described conditioning control unit is connected with described suction side Controlling solenoid valve 7, and the second control output end is connected with described exhaust side Controlling solenoid valve 10.
In addition, during in order to make compressor operating of the present invention, Security is higher, can be provided with the pressure accumulation stable-pressure device for keeping cylinder body internal air pressure constant between described suction side Controlling solenoid valve 7 and described exhaust side Controlling solenoid valve 10.Described pressure accumulation stable-pressure device comprises a pressure accumulation plenum 89 be connected with described cylinder body 1, be provided with one in described pressure accumulation plenum 89 for by air pressure voltage stabilizing piston 9 isolated for outer to cylinder body 1 internal air pressure and cylinder body air pressure, one end of described air pressure voltage stabilizing piston 9 is fixed on described pressure accumulation plenum 89 upper end by spring assembly 8.
