Description

The cold air-conditioning that alternating current and photovoltaic DC electricity dual-purpose hand control

Art

The utility model relates to a kind of household electrical appliance, especially the cold air-conditioning of AC/DC.

Background technology

At present, the cold air-conditioning of known family expenses is all by AC-powered, the cold air-conditioning on automobile, and the little efficiency of its volume is high, is not afraid of vibrations again, but the compressor of the cold air-conditioning of automobile is automobile engine to be driven.In order to energy-conserving and environment-protective, units concerned now then step promote I patent " family's dual track system power supply need not, few with, directly use system " (ZL201220245052.1) show referred to as " directly using formula photovoltaic generation ".Automobile cold idle call 180V to 220V photovoltaic DC electricity is powered to dc motor, the cold air-conditioning on driving automobile is carried out with dc motor, this is imagined everybody and all says well, in test, the cold air-conditioning of automobile, drive compressor no problem with powerful alternating current generator, but when using direct current generator, because power of motor is large, when switch opens with when turning off motor power, arcing wanted by switch, I once used the alternating current toggle switch of 30 amperes, also because of arcing, can only use first and second, switch contact just blows or adhesion.In order to can make alternating current and photovoltaic DC electricity dual-purpose, look for and a kind ofly can become again problem with the motor that AC and DC is dual-purpose.

Summary of the invention

In order to overcome the cold air-conditioning of current automobile use powerful direct current generator time, switch causes contact to blow the problem with adhesion because of arcing, this problem is solved with plug-in strip, in order to find universal motor, through repeatedly development test discovery, in existing alternating current generator, rotor is coil, stator be permanent magnetism with excitation, also can use by major part during 180V to 220V direct current, but series excited machine is first-selected, series excited machine is universal motor, therefore be general-purpose motor again, a few hectowatt of power has to several kilowatts, be applicable to all size air-conditioning to select.

The utility model solves the technical scheme that its technical problem adopts: it is made up of cold aircondition and AC/DC power set, ac-dc dual power supply conversion equipment three part.Cold air-conditioning on automobile, is made up of compressor, condenser, evaporator assembly, liquid storage dryer, throttling arrangement five major part, connects with flexible pipe.Here will illustrate, evaporator assembly includes the electromagnetic clutch control circuit on evaporimeter, temperature sensing controller, manual overvide and compressor.AC/DC power set, are made up of universal motor (series excited machine), belt pulley, belt, take-up pulley and electromagnetic clutch on the compressor.Ac-dc dual power supply conversion equipment, exports 12V Switching Power Supply by AC/DC, AC/DC motor changes plug-in strip, direct current presses down arc plug-in strip and forms.Its process of refrigerastion operation principle is: after AC-DC motor switches on power, electric machine rotation, after the switching knob of manual rotation evaporimeter, electromagnetic clutch adhesive, compressor operating, refrigerating fluid is compressed into the steam of HTHP, deliver to condenser, through fan blowout, dispel the heat outside body, the liquid of middle temperature high pressure, through liquid storage dryer and throttling arrangement, the liquid becoming low-temp low-pressure sends into indoor evaporator, becomes the gas of middle temperature low pressure after heat absorption, return compressor, start second time circulation.The radiator fan of air-conditioning condenser, evaporator assembly send the axial-flow fan of cold wind, electromagnetic clutch, use 12V powered by direct current, the output of development AC/DC is the power supply of 12V big current, also be a difficult problem of the cold air-conditioning of alternating current-direct current, dissect alternating current and export the galvanic Switching Power Supply of 12V, such as, power pack on desktop computer, it is by alternating current 220V current rectifying and wave filtering circuit, switched oscillation circuit, high-frequency impulse current rectifying and wave filtering circuit, sampling and this few part of controlling circuit of voltage regulation have been come, and the first step of Switching Power Supply is exactly 220V alternating current, direct current is become through filter rectification, and " directly sending out with formula photovoltaic " direct current electric pressure is 180V to 220V, direct current is connected on the output of Switching Power Supply after rectification, according to probationary certificate, reach requirement completely, in present specification, only direct current access place is described, aft section is not described, because this is well-known principle.

The beneficial effects of the utility model are, this cold air-conditioning, and adopt the cold air-conditioning assembly on automobile, the little efficiency of volume is high not to be afraid of vibrations, uses photovoltaic direct current, can not beat arc, also can with common alternating current, energy-conservationly facilitate again.
