Description

Alternating current and the dual-purpose air-source water heater of photovoltaic DC

Art

The present invention relates to the air-source water heater of a kind of household electrical appliance, especially AC/DC.

Background technology

At present, known air-source water heater, is all by AC-powered, along with relevant Unit then walk promote I patent " family's double-track system power supply need not, few, straight system System " (ZL201220245052.1) existing referred to as " directly using formula photovoltaic generation ", DC voltage 220V, the air-source water heater of development photovoltaic direct current supply is the needs of development of the situation, greatly The electrical equipment of power uses unidirectional current, and when switch is switched on and off power supply, arcing wanted by switch, makes Becoming switch contact to blow or adhesion, I am the most once with the alternating current toggle switch of 30 amperes, also because of Arcing, can only use first and second, in order to be able to make alternating current and photovoltaic DC electricity dual-purpose, looks for One can become again new problem with AC/DC compressor.

Summary of the invention

In order to overcome air-source water heater want arcing when using direct current and look for a kind of AC/DC The problem of compressor, the present invention provides a kind of AC/DC air-source water heater, solves Above-mentioned two problems.

The technical solution adopted for the present invention to solve the technical problems is: its structure is by air Can water heater condensing unit, AC/DC air conditioning system, ac-dc dual power supply conversion dress Put three part compositions.Air-source water heater condensing unit, in the lagging casing of drum-shaped be Water heater liner, centre is with two condensations up and down on copper pipe spirally-wound connected with outer casing Joint, is also equipped with cooling water inlet, hot water takes mouth, temperature indicator, temperature on shell Actuator, and control compressor electromagnetic clutch only with thermoregulator, control compression Machine clutch.AC/DC air conditioning system, uses automobile air conditioner compressor, with alternating current-direct current two Series excited machine be used as power, with electromagnetic clutch control compressor clutch state, use air Condenser made by energy water heater and liquid storage is dried throttling arrangement, vaporizer composition.AC/DC Power supply change-over device, is changed plug-in strip by ac-dc dual power supply, unidirectional current presses down arc plug-in strip, friendship DC dual-purpose output 12V Switching Power Supply composition.12V direct current all used by electromagnetic clutch, fan Electricity power supply, develops AC/DC and is output as the Switching Power Supply of the big electric current of 12V, be also to hand over One difficult problem of direct current air energy water heater, dissects the alternating current output galvanic switch of 12V Power supply, it is whole by alternating current 220V current rectifying and wave filtering circuit, switched oscillation circuit, high-frequency impulse Stream filter circuit, sampling and these several parts of controlling circuit of voltage regulation complete, and Switching Power Supply The first step be exactly 220V alternating current, the filtered unidirectional current that is rectified into, and " directly use formula light Volt generating " DC voltage is 220V, unidirectional current be connected to Switching Power Supply rectified after defeated Go out on end, according to probationary certificate, be fully achieved requirement, in present specification, only explanation At unidirectional current access, aft section does not illustrates, because this is well-known principle. Its work process is summarized as follows: after AC-DC motor switches on power, electric machine rotation, when When thermoregulator in air-source water heater is not reaching to design temperature, electromagnetic clutch is inhaled Close, compressor operating, refrigerating fluid is compressed into the steam of High Temperature High Pressure, delivers to air energy thermal Hydrophone dispels the heat, the water in heat hot water device, it is dried throttling arrangement through liquid storage, vaporizer, Return compressor, start second time circulation.Temperature is set when hot water temperature reaches thermoregulator When spending, electromagnetic clutch departs from compressor, and compressor does not works.

The invention has the beneficial effects as follows, use automobile air conditioner compressor, use photovoltaic DC electricity Arc will not be beaten, it is also possible to common alternating current, energy-conservation facilitate again.
