Description
Technical field
It the utility model is related to a kind of Stirling generating and heating system.
Background technology
Existing disk system is generated electricity using Driven by Solar Energy Stirling engine, its flexible arrangement, system rule
Mould is changeable；Both can the operation of single complete equipment, can also generate electricity in groups on a large scale.But there is no heat storage capacity, can only have too
The fine day of sun generates electricity；And because the position of Stirling engine is not fixed（Rotated with dish stand）And it is difficult to the storage of system
Heat or afterburning.The power output of generator is easily influenceed by weather, and even in daytime, its intensity of sunshine is also constantly to change
, therefore the electric energy exported is unstable, needs to be adjusted to stable output before accessing power network.
It is inadequate to the utilization rate of heat energy at present, it is generally only the single electric energy that converts heat energy into, and in people's life often
Often also need to be used to freeze or heat by electric energy, 2 conversions are thus carried out to electric energy, so can bring one layer of damage again
Consumption.
The content of the invention
The technical problems to be solved in the utility model：For the unstable and solar energy of existing device of solar generating generating
The problem of Land use systems are single, there is provided a kind of to store heat energy with stable electric generation and be capable of supply that hot water is with what is freezed
System.
Technical solutions of the utility model：
A kind of Stirling solar generates electricity and refrigeration system, including heat collector, stirling generator group and circulation line,
Heat transfer medium is circulated by circulation line between heat collector and stirling generator group, heat collector and stirling generator
Heat-storing device is provided between group, the heat transfer medium come out through stirling generator group enters heat collector or heat-storing device, passes through
Heat transfer medium after heat collector heating enters heat-storing device, stirling generator group or Stirling cooling unit, heat accumulation dress
Heat transfer medium in putting enters stirling generator group, and the heat transfer medium in heat-storing device enters stirling generator group, Si Te
Woods refrigeration unit connects cool-heat-exchanger.
Stirling generator group connects air-water heat exchanger, and air-water heat exchanger connects heat storage water tank and recirculated water respectively
Pump.
Stirling generator group connects hot water exchanger, and hot water exchanger connects heat storage water tank and water circulating pump respectively.
The heat collector is arranged on dish-style, slot type or tower concentrator.
Heat transfer medium in heat-storing device can also pass into heat collector.
The junction installation valve of each pipeline, passes through the opening and closing of controller control valve door on circulation line.
The beneficial effects of the utility model：
The system using heat-storing device by absorption on daytime come solar radiation energy stored in the form of heat energy, pass through
Controller adjusts the flow of heat energy, and the heat energy ensured into Stirling engine is maintained at a more stable value, to night
Between or discharge again during cloudy illumination deficiency and carry out hot generating, make the generating of power station continuous-stable.Using heat-storage technology and
Dish-style Stirling solar electric generating system is combined the cogeneration system of composition, can not only there is the work of stable network load
With, moreover it is possible to the energy loss during system frequent start-stop is reduced, improves solar energy utilization ratio, solar energy is provided continuous electricity
Can be accomplished.
By air-water heat exchanger, the Hot-blast Heating cold water after directly being generated electricity using stirling generator group, accelerate hot water
Formation speed, suitable for the place big to hot water supply requirement amount.
During generating, stirling generator group itself is needed to radiate, and in the presence of water circulating pump, cold water is sent
Heated on to the hot water exchanger of stirling generator group, be then stored in heat storage water tank, realize the recycling of waste heat.
Heating combined equipment and heat-storing device can be individually or simultaneously to stirling generator group and refrigeration unit heat supply, Si Te
Woods generating set is used to generate electricity and heat supply, and stirling refrigeration unit is used to freeze.Utilize the characteristic of Stirling engine, fully profit
With solar thermal energy, accomplish that system heat supply, generating, a refrigeration have both, form the Stirling with heat storage function of complete set too
Positive energy thermoelectric cold triple supply system.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Air after the heating of heat collector 1 can enter heat-storing device 2, Stirling starts group of motors 3 and Stirling cold
But unit 14.High-temperature gas into heat-storing device 2 returns to heat collector 1 after heat exchange；Start the He of group of motors 3 into Stirling
Air after Stirling cooling unit 14 exchanges heat enters air-water heat exchanger 13, finally enters the heat exchange of heat-storing device 2 and continues cycling through
Or continued cycling through into heat collector 1.
In the course of work of stirling generator group 3, radiated by hot water exchanger 4, under the drive of water circulating pump 9
Heating cold water is simultaneously sent into heat storage water tank 5.
Stirling refrigeration unit 14 is made up of two Stirling engines, a Stirling engine as prime mover, from
The external world absorbs heat and produces power.An other Stirling engine realizes gas as driven machine under the drive of prime mover
Kind of refrigeration cycle, freezer 17 or other places for needing to freeze are connected to by cool-heat-exchanger 16.
During generating, stirling generator group 3 itself needs to radiate, in the presence of water circulating pump 9, by cold water
It is sent on the hot water exchanger 4 of stirling generator group 3 and heats, is then stored in heat storage water tank 5, realizes the recycling of waste heat.
Hot-air by stirling generator unit 3 heat exchange after, also to pass through air-water heat exchanger 13, finally again from gas-
Water heat exchanger 13 enters heat collector 1 or heat-storing device 2.Stirling generator is directly used by air-water heat exchanger 13
Hot-blast Heating cold water after the generating of group 3, accelerates hot water formation speed, suitable for the place big to hot water supply requirement amount.
