The working method of a kind of Hydrogen Energy and the cogeneration system of solar energy complementation, including following working method:
(1) photovoltaic charge mode
It is sunny, when needing to power but being not required to heat supply, second switch 18 and third switch 26 are disconnected, it is described steam compressed Formula heat pump system 2 and proton exchange membrane fuel cell power generation system 1 do not work, when 4 voltage of DC bus is less than lower voltage limit When, it is closed first switch 33, the direct current of photovoltaic array 31 output voltage and electric current real-time change, this direct current is through the After one DC-DC converter, 32 voltage stabilizing, DC bus 4 is accessed, and charge to the accumulator group 5 of access DC bus 4;When straight When flowing 5 voltage of busbar higher than upper voltage limit, first switch 33 is disconnected, photovoltaic array 31 stops output direct current, from institute The occasion that illumination etc. needs electric power to apply can be used for by stating the direct current taken out on DC bus 5.
(2) fuel cell charge mode
Under rainy weather or night condition, when needing power supply, first switch 33 and third switch 26, solar energy are disconnected Photovoltaic generating system 3 and vapor compression heat pump systems 2 do not work, when 4 voltage of DC bus is less than lower voltage limit, are closed second Switch 18, proton exchange membrane fuel cell power generation system 1 are started to work, and hydrogen enters proton exchange membrane by hydrogen inlet 111 and fires Expect that battery stack 11, the air through being overpressurized enter proton exchange film fuel cell electric piling 11 from air intlet 113, is handed in proton It changes 11 internal hydrogen of film fuel cell electric piling to react with the oxygen in air, generates direct current and water, the direct current is through second After 12 voltage stabilizing of DC-DC converter, DC bus 4 is accessed, and charge to the accumulator group 5 of access DC bus 4, work as direct current When 4 voltage of busbar is higher than upper voltage limit, second switch 18 is disconnected, it is defeated that proton exchange membrane fuel cell power generation system 1 stops electric current Go out, the direct current taken out from DC bus 4 is used to the occasion for needing electric power application such as illuminate.
When proton exchange film fuel cell electric piling 11 generates direct current, 11 inside of proton exchange film fuel cell electric piling generates Cooling water in cooling water tank 14 is pumped into the cooling water inlet of proton exchange film fuel cell electric piling 11 by heat, the water pump 13 115, after cooling water absorbs the heat inside proton exchange film fuel cell electric piling 11, temperature increases, and is flowed from cooling water outlet 116 Go out to return cooling water tank 14.
Cooling water from cooling water outlet 116 flow out return cooling water tank 14 approach be:
When interior needs heating, the first valve 141 is opened, the second valve 142 is closed and third valve 143, temperature is raised cold But water transfers heat to the surface of radiator 17 by second valve 142, and passes through radiation and cross-ventilated side Formula heats room air, realizes that heating, cooling water are reduced to temperature after indoor radiating, is returned using third valve 143 Cooling water tank 14 is conducive to the consumption power of the heat dissipation load and radiator fan 15 that reduce cooling water tank 14;
When interior need not heat, it is closed the first valve 141, opens the second valve 142 and third valve 143, temperature is raised Cooling water directly returns to cooling water tank 14 by the first valve 141.
In cooling water tank 14, cooling water dissipates the heat to the air, and temperature reduces, and then has circulating cooling proton The ability of exchange film fuel battery pile 11.
(3) heat pump heating mode
When needing heating, it is closed third switch 26, vapor compression heat pump systems 2 work, the direct current in accumulator group 5 Direct current refrigeration compressor 21 is supplied, direct current refrigeration compressor 21 operates, and compresses refrigerant gas, and refrigerant gas freezes through direct current After compressor 21 compresses, temperature raising, pressure rise get in side heat exchanger 22, and indoors in side heat exchanger 22, high temperature is high The refrigerant gas of pressure accelerates convection current to room air heat release, and by indoor fan 25, so that room air is heated, puts Refrigerant after heat is condensed into the liquid of high temperature and pressure, and when flowing through restricting element 23, and pressure reduction becomes low-temp low-pressure The refrigerant air-liquid mixture of gas-liquid mixture, low-temp low-pressure subsequently flows into outdoor heat exchanger 24, in outdoor heat exchanger 24 The middle heat for absorbing outdoor air and evaporation, become refrigerant gas, refrigerant gas is by direct current refrigeration compressor 21 again Air entry sucking is compressed again, is moved in circles, in the process, the heat absorbed from outdoor air is discharged by refrigerant In room air, indoor air temperature increases, and realizes heat pump heat supply
Vapor compression heat pump systems 2 work, solar photovoltaic generation system 3 and Proton Exchange Membrane Fuel Cells power generation system System 1 does not work, and the electricity in accumulator group 5 is gradually exhausted, and the voltage of DC bus 4 will continuously decrease, when DC bus 4 When voltage is less than lower voltage limit, when sunny, individually open solar photovoltaic generation system 3 and charge to accumulator group 5, When sunlight is inadequate or does not have sunlight, individually opens proton exchange membrane fuel cell power generation system 1 and charge to accumulator group 5, make The voltage recovery of DC bus 4, when sunny, if individually opening solar photovoltaic generation system 3, DC bus 4 Voltage is still relatively low, then can open solar photovoltaic generation system 3 and proton exchange membrane fuel cell power generation system 1 simultaneously to storage Battery pack 5 charges, to maintain the voltage stabilization of DC bus 4.
The utility model comprehensively utilizes Proton Exchange Membrane Fuel Cells, solar-energy photo-voltaic cell, the advantage of heat pump respectively, can With off-grid operation, can also be used in the place of not power grid;The supply of electric energy and thermal energy can be taken into account, flexibility is good;Heating effect Rate is high, takes full advantage of the electric energy and waste heat of fuel cell;Comprehensive energy utilization rate is high.
