Further, described storage cool equipment comprises ice cell, cooling medium reservoir.
Further, heat transfer unit (HTU) is used the fusion tray of thermal transmission and storage technology.
Further, the hot refrigerator of heat sound is used acoustic refrigeration technology.
Further, heat transfer unit (HTU), refrigeration transmitting device adopt adiabatic transmission technology.
Refrigerating plant in the utility model is with thermo-acoustic technology, and solar tracking optically focused technology and high-temperature heat accumulation technology combine, the novel device that utilizes solar energy and thermo-acoustic technology to freeze.
Theoretical foundation of the present utility model:
The thermo-acoustic technology principle: heat and noise are associations, all are the performances of molecular motion.Verified now, if allow oscillating fluid in micro-channel, form controlled sound field, simultaneously set up thermograde along passage, this gradient is under the non-linear modulation of sound field so, form heat wave, it can put into the contained sound field of oscillating fluid, is orderly sound field so heat energy will be directly changed into.If reasonably regulate sound field, the temperature difference and channel size, the three is coordinated, so just the heat that can utilize this temperature difference to drive evokes orderly strong sound oscillation, Here it is so-called " self-excitation thermal acoustic oscillation ", this process is a reversible process, and the hot refrigerator circulation of heat sound is exactly to have used above principle, with acoustic refrigeration.
Solar tracking optically focused technology: by the signal of sunshine direction sensor output solar azimuth, height, accept to handle and the tracking driver motor is sent instruction driving reflector proofread reflective laying for direction gatherer by the DCS system, this feedback procedure changes constantly repetition with position of sun, realize following function, the solar tracking beam condensing unit can be individual unit, a plurality of unit or array.
The high-temperature heat accumulation technology: the storage mode of regenerative resources such as wind-force, photovoltaic can only adopt the electric power storage pattern, and the electric power storage cost is very high, in big capacity power station, can't adopt, therefore photovoltaic and wind-force generation electric energy is very big with solar energy and wind energy fluctuation, if ratio is excessive in electrical network, can produces electrical network and impact.The fusion tray of thermal transmission and storage technology is a kind of advanced person's a heat transfer heat storage technology, and it is low that it has a cost, and the regenerator temperature height is simultaneously not flammable, has advantages such as very high heat transfer coefficient, thermal capacitance and density, is a kind of desirable heat storage medium.Be the adoptable extensive heat storage technology of popularizing of solar energy optical-thermal, the heat energy of exportable steady and continuous has overcome existing water vapour heat reservoir heat transfer coefficient, thermal capacitance and low density defective.
With traditional hot machine mutually the hot refrigerator of specific heat sound have lot of advantages: it has reduced movable member (1), and structure is very simple.Thermoacoustic engine and the combination of thermoacoustic refrigeration machine are made the refrigeration machine that heat drives.It does not have movable member fully, has the reliability of height, is particularly suitable for the long-life refrigerator of space with the cooling of low-temperature electronics device.(2) conventional chiller be with fluorine Lyons as working media because fluorine Lyons is to the destruction of atmospheric ozone layer, greenhouse effects are obvious day by day, the environment that the mankind depend on for existence is destroyed.And the hot refrigerator of heat sound is a kind of new, pollution-free low noise Refrigeration Technique, meets environmental protection requirement.(3) the hot refrigerator of heat sound can directly utilize inferior heat energy, for example solar energy, underground heat etc.(4) thermal conversion efficiency height: be that 1.6 times of photovoltaic, cost of manufacture are low: be photovoltaic 1/5, the reliability height: the few or nothing of mechanical moving element, environmental protection.
