Its advantages include high temp raised by collecting heat, the switching between refrigerating and heat supply for continuously refrigerating and generating heat, compacts structure, small size, high refrigeration power and high utilization rate of solar energy.
Description
The present invention relates to a kind of refrigeration and heat supply integration unit, particularly relate to a kind of solar refrigerating and heating integration unit.
Existing solar energy solid adsorption refrigerating device is divided into two types, and a kind of is the batch (-type) refrigerating plant, and it is a cycle period with one round the clock, sunshine on daytime direct heat solid adsorbent bed desorption, cold-producing medium liquefaction, solid adsorbent bed cooling absorption in evening, cold-producing medium sweat cooling.This type of device cycle period is long, and freezing capacity is low, and only with intermittent duty, only is suitable for ice making.Another kind is a double bed backheat continuous type refrigerating plant, and it at first relies on the solar thermal collector thermal-arrest, utilizes heat-transfer working medium heat transfer heat solid adsorbent bed desorption then, adopts double bed or many alternately absorption and desorption realization continuous coolings.This type of device cycle period is short, bed with bed between can backheat, thereby refrigerating efficiency height.But this type of device volume is huge, system complex, and the overall refrigerating efficiency of solar energy is low.
The objective of the invention is: make a kind of heat-collecting temperature height, vacuum tube solar heating element and the compound one of solid adsorbent bed, employing refrigeration and the mutual switching mode of heat supply function, circularly cooling continuously, and can produce heat energy simultaneously, compact conformation, volume is small and exquisite, refrigeration effect brilliance, solar airconditioning refrigeration and heat supply comprehensive utilization device that the overall utilization ratio of solar energy is high.
The objective of the invention is that following mode realizes: it is by a light-focusing type vacuum tube solar heating element--and solid adsorbent bed complex (1), spherical boiler (4), spherical cold water storage cistern (5), condenser (10), reservoir (11), evaporimeter (12) are formed.
The light-focusing type vacuum tube solar heating element--solid adsorbent bed complex (1) is made of two parts.First is concentrator (2), and it can be a CPC flute profile concentrator, also can be parabola flute profile concentrator; Second portion is a vacuum tube--solid adsorbent bed complex (3), it is made up of vacuum tube (16), refrigerant vapour distributor pipe (14), heat exchanger (15), solid adsorbent bed (20).Vacuum tube (16) connects firmly together with certain relative position with concentrator (2), makes sunlight converge on the vacuum tube (16) after concentrator (2) reflection:
Vacuum tube (16) can be an all-glass vacuum tube, also can be the glass metal hot pressing envelope vacuum tube that has the metal absorber;
Solid adsorbent bed (20) is the stainless steel cylinder of sealing, its inside has water cycle heat exchange device (15) and refrigerant vapour distributor pipe (14) and contains the pipe of solid absorbent (21) by certain way, it can directly insert in the vacuum tube (16), closely contact formation vacuum tube--solid adsorbent bed complex (3) with vacuum tube (16), also can adopt the hot pressing encapsulation method to become vacuum tube directly as the metal absorber with vacuum tube (16) sealing by fusing--solid adsorbent bed complex (3).In two adsorbent beds, wherein an end of an adsorbent bed is communicated with magnetic valve (6), water circulating pump (13) and cold water storage cistern (5) by cold water pipe water inlet (19), and the other end is communicated with magnetic valve (7) and boiler (4) by hot-water line delivery port (17); The another adsorbent bed is communicated with magnetic valve (8), water circulating pump (13) and cold water storage cistern (5) by cold water pipe water inlet (19) equally, is communicated with magnetic valve (9) and boiler (4) by hot-water line delivery port (17).Two adsorbent beds are communicated with condenser (10), reservoir (11) and evaporimeter (12) by the refrigerant vapour mouth of pipe (18) that distributes simultaneously;
Spherical boiler (4), spherical cold water storage cistern (5) are formed by connecting by the water cycle heat exchange device (15) of water circulating pump (13) and solid adsorbent bed inside;
Condenser (10), reservoir (11), evaporimeter (12), solid adsorbent bed (20) are formed by connecting by the refrigerant vapour distribution mouth of pipe (18);
Light-focusing type vacuum tube--solid adsorbent bed complex tilts to install according to different geographic latitudes.
After the operation beginning, solar radiation concentrator (2), concentrator (2) converges to vacuum tube (16) with sunlight and goes up directly its inner adsorbent bed (20) of heating, the inner adsorbent (21) of adsorbent bed (20) is subjected to thermal desorption to go out refrigerant vapour, and refrigerant vapour is condensed into liquid again and flow to reservoir (11) storage in condenser (10).After the adsorbent desorption is complete, start water circulating pump (13), water in the cold water storage cistern (5) is squeezed into water cycle heat exchange device (15) cooling adsorbent bed (20), and the sensible heat that adsorbent bed (20) is inner spreads out of heat supply, and this moment, the heat energy of sunshine incident also spread out of heat supply in the lump.Along with adsorbent bed (20) is cooled to certain degree, adsorption process begins, the liquid start vaporizer refrigeration in the evaporimeter (12).When absorption reached capacity, the circulating pump of closing down (13) heating desorption process began again.So go round and begin again, under the irradiation that sunlight continues, can realize the quasi-continuous refrigeration and the heat supply that are interrupted.
If two same bed alternate runs, the two a shared circulation of cover water tank and air-conditioning refrigeration system, then whole system forms totally continuous solar airconditioning refrigeration and heating system.
Advantage of the present invention and good effect are as follows:
1, owing to adopt vacuum tube--absorber complex thermal-arrest, direct irradiation of sunlight adds heat-adsorbent, efficiency of heating surface height, and the system architecture compactness, volume is small and exquisite.
2, by the switching between heating and the refrigerating function, realized continuous circularly cooling.
3, device is outwards supplied cold and heat simultaneously, and the overall efficient of utilizing of system's solar energy is high.
4, the circulation of the discontinuity by cooling water is the cooling and the heating process of discontinuity with the prolonged exposure thermal conversion of sunlight.
5, owing to removed many circulatory systems from, it is very easily combined with building, strengthened the practicality of solar airconditioning greatly.
