Description
Technical field
The present invention relates to a kind of aircondition that utilizes solar refrigeration, especially relate to a kind of solar absorption type air conditioner of family expenses.
Background technology
As common absorption type refrigerating principle, as far back as the forties in last century, the refrigerator car on Britain's Liverpool train is exactly this absorption type air-conditioning.But because of refrigerating efficiency is low, people have invented absorption refrigeration again subsequently, and just winning with its high efficiency appears in this air-conditioning at the beginning.Therefore, the absorption type air-conditioning just disappears from people's sight gradually.Up to seventies in last century for the second time after the oil crisis, energy problem looms large, and it is serious day by day to add worldwide environmental pollution, and people put into sight on the solar energy again gradually.And the exploitation of solar energy, what people at first expected is exactly air-conditioning, and this is the strongest because of working as the radiation of sun in summer energy, environment temperature is also the highest, and air-conditioning is as a kind of high energy consumption, and and for example this is strong for dependency in the life, can freeze with solar energy, just become the focus of people's common concerns.Therefore, the imagination of solar airconditioning is also just arisen at the historic moment.
The research and development solar airconditioning, why people will throw in sight on the absorption type air-conditioning, and this is because the solar energy autologous density is lower, and energy is unstable again, but solar energy does not pollute, do not change money thereby absorption type refrigerating and be unique a kind of be the refrigeration process of power with the thermal source.Because solar energy shape generating its cost so far is still high, and absorption refrigeration to be unable to do without with electric power be power, be the adsorption-type solar air-conditioning of power therefore with the thermal source, special household small-sized solar absorption type air-conditioning just causes people's attention especially.
The adsorption-type solar air-condition principle says that from using technology is ripe.Domestic solar absorption type air-conditioning is consistent with common absorption type air conditioning applications principle.So-called absorption type air-conditioning is exactly to utilize the absorption of adsorbent to its evaporimeter liquid adsorption matter, making the heat on liquid adsorption matter surface be adsorbed agent constantly takes away, the steam of liquid adsorption matter also just constantly is adsorbed like this, and the surface of liquid adsorption matter is constantly evaporation just, constantly is pulled away.Constantly taken away because of heat of vaporization at last, so temperature also and then constantly descends.Reach the temperature of refrigeration at last.If being water (also can be methyl alcohol, liquefied ammonia etc.) water, liquid adsorption matter just progressively becomes ice (cold) water.If at this moment the adsorbed liquid of adsorbent has reached saturation state, then this adsorbent has just stopped absorption, the end of refrigeration that Here it is.This stage is the refrigerating capacity that is obtained in the heat changed of refrigeration and this stage, and their ratio is exactly our said at ordinary times refrigerating efficiency.The whole desorptions of adsorbate adsorbed in this stage adsorbent are come out, the way of employing heats adsorbent exactly.We utilize solar focusing to collect the heat of solar energy, and its purpose is used to add heat-adsorbent exactly, up to the adsorbate of saturation state is all desorbed in adsorbent.From adsorbent, desorb the one-period of kind of refrigeration cycle that Here it is to adsorbate from beginning to adsorb adsorbate.What of cycle, we claim its efficiency factor.Their efficient of obvious different adsorbent and different adsorbate (claim again them be work to) is not the same.As if the data of the efficient of adsorption-type solar air-conditioning experiment at present all do not have too many breakthrough between 0.25 to 0.35, and the efficient of absorption type air-conditioner is generally all more than 0.8.
The reason that the adsorption-type solar air-conditioner efficiency is low is commercially available adsorbent at present, resembles active carbon, silica gel, synthetic Buddhist stone (claiming molecular sieve again) activated alumina, their thermal conductivity is all very low, thermal capacitance is also very little, and the poor performance of ubiquity heat and mass causes efficient very low.On various adsorbents, add various metal powder compression mouldings though there is report to have the people to adopt, or on device, increase heat-transfer metal silk screen or the like, also have the device total thermal capacitance on carried out well-designed, but effect is not remarkable, so far the efficient according to data introduction absorption examination air-conditioning does not all have to surpass 0.5, but people's confidence is forfeiture not, and under the special current power supply breach big background like this, the prospect of solar airconditioning is tempting.
The applicant discloses a kind of domestic solar energy intelligent artificial environment system in application for a patent for invention 02110953.2, by simple in structure, with low cost, but the light collecting heater of the long-term open-air trouble-free solar full-automatic tracking of use, energy storage equipment and continuous cooling, the solar energy high temperature absorption type air conditioner that refrigerating efficiency is high are formed, utilize the circulation of heat medium, form the artificial intelligence environmental system in conjunction with other apparatus for household use, making full use of solar energy is service for life, satisfies the various needs of people.Solar energy high temperature absorption type air conditioner wherein is made up of condenser, adsorbent bed, air-conditioning heater and evaporimeter; Heat-conducting medium feed liquor pipeline, fluid pipeline are connected with air-conditioning heater, and two groups of adsorbent beds of superheated vapor heating pipe line one end of air-conditioning heater combination in parallel are communicated with, and the other end is communicated with condenser by circulating fan; Cooling line is communicated with circulating water line in the adsorbent bed; The condensate line of condenser is communicated with evaporimeter, and the condensed steam pipeline of evaporimeter is communicated with adsorbent bed, and solenoid control is passed through in the control of pipeline.Adorn a rigidity hanging basket in the adsorbent bed, adsorbent profiled sheeting and cooling coil are separately fixed in the hanging basket.Be respectively equipped with the heat and mass passage between interior every layer of adsorbent profiled sheeting of whole adsorbent bed and the cooling coil.Adsorbent bed employing molecular sieve and water are right as working medium.
Summary of the invention
The present invention further improves on original solar energy high temperature absorption type air conditioner basis, provide a kind of and directly utilize hot-air after the solar energy heating as heating agent, have little energy starting, thermal conductivity height, thermal capacitance loss less, the domestic solar absorption type central air-conditioning of excellent properties such as fast, the refrigerating efficiency height of desorption rate.
Domestic solar absorption type central air-conditioning, comprise solar energy gas heater, cold air pump, absorption type central air conditioner main machine, cooling water cycle water case, underground storage water cooling pond, air-conditioning draught fan, the absorption type central air conditioner main machine is made up of condenser, adsorbent bed and evaporimeter; The heated air pipeline of solar energy gas heater is communicated with two groups of adsorbent beds of combination in parallel in the absorption type central air conditioner main machine, and adsorbent bed is communicated with condenser and evaporimeter respectively by gate valve in the exit up and down; Cold air pump main road is communicated with solar energy gas heater and adsorbent bed respectively; The condensate line of condenser is communicated with evaporimeter by the capillary choke valve; The cooling water pipeline of condenser is communicated with the cooling water cycle water case by water circulating pump; The condensate liquid pipeline of evaporimeter is communicated with underground storage water cooling pond; The cooled-air line of underground storage water cooling pond is communicated with air-conditioning draught fan.
Described condenser center upper portion is provided with moisture trap, and pressure sensor is equipped with on separator top.Described moisture trap is a garden shape groove, the net volume that the dress stainless steel cloth is rolled in the groove.
Described solar energy gas heater comprises copper pipe, vacuum layer, high-boron-silicon glass pipe, the high-boron-silicon glass pipe is a vacuum layer between copper pipe and high-boron-silicon glass pipe outside copper pipe, the inner woven wire of filling of copper pipe, the lower end has cooling gas inlet, and the upper end has the heated air outlet.
Gas in the described solar energy gas heater is air or inert gas.
Described adsorbent bed and condenser also are provided with pipeline and are communicated with boiler.
Use the medium of cold air in the solar energy gas heater of the present invention as quick cold and hot exchange, the inert gas of also available O family is as the medium of quick cold and hot exchange, can reclaim inert gas by circulating system, its better effects if, but cost is higher, therefore general employing air is made medium, and effect of the present invention and specific embodiment explanation also are that medium describes with the air.
The present invention passes through the solar energy heating cold air as domestic solar absorption type central air-conditioning thermal source, by about two adsorbent beds, when the hot air left adsorption bed, adsorbent is constantly heated, be heated to adsorbate (water) when reaching evaporating temperature, entrainment of warm air steam and is entered condenser, carries out heat exchange with condenser coil, fin etc. in the condenser.Meanwhile water circulating pump begins to start, to force to quicken condensation.Hot-air cooling back steam becomes condensed water, but the condenser internal pressure is constant, and the hot-air that still has an a small amount of water vapor rises to top and moisture trap and carries out again heat exchange.Isolated condensed water flows to wall by stainless steel cloth and flows back to condenser, after hot-air then flows to water heater and hot water heat exchange from the outlet of pressure sensor, and the cold air emptying.Though in this moment left adsorption bed adsorbate all desorbs (desorption) in the bed temperature of adsorbent still high, from air pump, introduce cold air for this reason, carry out heat exchange with left adsorption bed, make left adsorption bed rapidly cooling reach normal temperature.So far the desorb work of left adsorption bed is all over.The condensed water that meanwhile has certain pressure, capillary choke valve by condenser enters evaporimeter, because the unexpected decrease temperature and pressure of capillary choke valve, the heat steam of evaporator surface is adsorbed by right adsorption bed, the capillary choke valve is successively sent into condensed water like this, and the heat steam that just constantly occurs being evaporated continuously on the evaporimeter liquid level is that right adsorption bed is adsorbed.Just cooling constantly of the liquid of evaporimeter inside like this, whole process of refrigerastion continues like this, up to the adsorbate of the adsorbent bed state that reaches capacity.So far the adsorption-type solar central air-conditioning among the present invention has just been finished a circulation overall process from desorption to absorption refrigeration.
Be intermittence and the unstability that overcomes solar energy self, the present invention is located at underground and evaporimeter with the refrigerant storage cistern and contacts by pipeline, and so just storage is cooler than undergroundly, has significantly reduced heat-energy losses and has also reduced the cost that high-temperature medium is incubated.Like this, both just do not have the solar energy supply in 3-5 days, central air-conditioning is because the storage of refrigerant still can guarantee work as usual.
Because the solar radiation in morning is not strong, it is longer to be heated to the relative accumulated time of certain heat, and liquid-carrier can not directly carry out heat exchange again, and the centre is bigger again by the loss of pipeline thermal capacitance.Therefore adopt air as carrier, starting is fast, and the thermal capacitance loss is few.And do not react the adsorbent long service life each other.Air both can be used as heat carrier also can make cold carrier, does not pollute, and does not need to store, use promptly, need not abandon it, do not have cost, so operation of air conditioner cost of the present invention is very low.

Fig. 1 is the main device schematic flow sheet of system of the present invention;
Fig. 2 is the structural representation of air heater of the present invention.
The specific embodiment
As Fig. 1,1 is the solar energy gas heater, and 2 is the cold air air pump, and 3 is the absorption type central air conditioner main machine, and 4 is the cooling water cycle water case, and 5 is underground storage water cooling pond, and 6 is boiler, and 7 is air-conditioning draught fan.
By air pump 2 cold airs send into solar energy gas heater 1 in carry out continuous heat exchange.The hot-air of heat exchange is started working by the adsorbent bed 32 that pipeline is conveyed into the main frame 3 of central air-conditioning, and how much quantity of heater polyphone need decide increase and decrease by refrigerating capacity, and all conveyance conduit is all through lagging.3 minutes three big parts of central air conditioner main machine: i.e. condenser 31, adsorbent bed 32, evaporimeter 33.The shell of condenser 31 can be aluminium alloy pressure pouring, also can be cast iron.Have radiating ribs on the condenser 31, wall will approach, and reduces the thermal capacitance loss as far as possible.Be the condenser coil 313 of band heat absorbing sheet in the condenser 31, be communicated with cooling water cycle water case 4 that circulation is recirculated cooling water in the pipe by water circulating pump 41.Condenser coil 313 existing standard design only need selection standard spare to get final product.
Be provided with moisture trap 311 in condenser 31 center upper portion, promptly a garden shape groove is adorned the net volume that stainless steel cloth is rolled in the groove, is used to separate air water.Pressure sensor 312 promptly is equipped with on moisture trap 311 tops in the exit of condenser 31, is exhaust outlet here, controls condensing pressure again, and capillary choke valve 323 will have certain pressure in the condenser 31 when the discharging condensed water.
Two adsorbent beds are 32a and 32b about the absorption type central air conditioner main machine.The material of adsorbent bed 32 makes with stainless sheet steel that (steel plate thickness is as long as guarantee to be subjected under the enough situations of force intensity, and material is got over Bao Yuehao, and purpose is to reduce the thermal capacitance loss of adsorbent bed.Adsorbent bed 32 skins add heat-insulation layer, and the heat-insulation layer outside is the protection decorative layer, and the top and the bottom of each adsorbent bed are equipped with flat gate valve 323a, 323b respectively, and the hole of gate valve is big as far as possible, allows hot-air, adsorbate by not being subjected to resistance.The top of adsorbent bed 32 and condenser 31 meet, and are hot-airs, steam, the shared pathway that carries out heat exchange.The bottom of adsorbent bed 32 and evaporimeter 33 communicate, and are the passages of adsorbent bed 32 absorption adsorbates, accomplish that non-resistance is unimpeded.The web plate 324 of ventilation is equipped with in adsorbent bed 32 bottoms, is the weight of supporting adsorbent on the one hand, and the aspect also is the passage of hot blast and adsorbate refrigeration in addition.Some conduits 322 be housed be passage in adsorbent bed 32a and the 32b for heat and mass.Conduit 322 axially every some distances by garden week five equilibrium to account for aperture some, for heat and mass in the system, the unlikely system internal resistance that causes is excessive.Adsorbent 321 fills up adsorbent bed, exports after some gaps cooling air heat exchange is stayed on top.Left and right sides adsorbent bed 32a and 32b form one group of integral body and are fixed.
Condenser 31 is communicated with evaporimeter 33 by capillary choke valve 323, and capillary choke valve 323 is other parts of the key of freezing, and standard product is arranged.But evaporimeter 33 main bodys can with aluminium alloy pressure pouring also cast iron or thin plate make, can not leak air during the air conditioner overall package.
By the hot-air that solar energy gas heater 1 is sent here by pipeline, this moment, left plate gate valve 322a closed, and left plate gate valve 323b opens, and hot-air enters left adsorption bed 32a and the interior adsorbent 322 (can select for use molecular sieve and water conservancy project to oppose herein) of adsorbent bed carries out heat exchange.After the heat exchange, the heat of hot-air partly is adsorbed agent and absorbs, and part is brought condenser 31 into together with the steam of adsorbate.Hot-air constantly replenishes, adsorbent then constantly is heated, the water of adsorbate also is heated simultaneously, when reaching the temperature of evaporation, the steam of adsorbate just is evaporated in the hole of adsorbent, adsorption particle is made up of countless holes, and adsorbent surface is long-pending can be reached about the 400-750m2/ gram, has very strong adsorption capacity is arranged.The hot-air that enters condenser 31 with a large amount of steam and condenser 31 interior condenser coils 331 carry out a cold and hot exchange, at this moment water circulating pump 41 starts, recirculated water is carried out forced circulation, change chronicly if depend merely on Natural Circulation cooling, and influence the desorption of front, also influence the absorption of back, to start water circulating pump 41 for this reason, improve the cooling water circulation rate, quicken the condensed water condensation, to improve air-conditioner efficiency.Steam is condensed into condensed water, the hot-air cooling, but the pressure in the condenser 31 can not become.
Carry out gas-water separation by moisture trap 311 again when having the hot-air that small amount of moisture enters condenser 31 tops.The water that separates flows back to condenser 31 by stainless steel cloth and wall.Hot-air then continues to rise to the position of pressure sensor 312 in the exit of condenser 31, guaranteeing under the constant situation of system internal pressure, the portion of hot air that exceeds pressure, outlet by pressure sensor 312 tops, after entering into the outer water of coil pipes 61 and coil pipe in the boiler 6 and exchanging, remaining heat is few, and cold air is with regard to emptying.
Temperature still keeps very high in this moment whole desorbs of left adsorption bed 32a (desorption) but the adsorbent bed, nature is long cool time, utilize air pump 2 to enter cold air from right (left pipeline is sent cold air into solar heater 1) pipeline for this reason, this moment, magnetic valve a closed, b opens, c opens, and d opens, and the cold air of introducing enters left adsorption bed 32a and adsorbent carries out heat exchange.Heated cold air goes out to enter boiler 6 through the d valve and carry out heat exchange, cold air emptying after the heat exchange from the c valve.By after like this constantly heat exchange, left adsorption bed 32a is cooling rapidly just, reach set point of temperature after, the desorb of left adsorption bed 32a (desorption) work just is all over.Meanwhile, the condensed water that has certain pressure enters evaporimeter 31 by capillary choke valve 323, because capillary choke valve 323 unexpected decrease temperature and pressure, the heat steam on evaporimeter 33 surfaces just by right adsorption bed 32b adsorbed (this moment flat gate valve 323a open wide and flat gate valve 323b close), capillary choke valve 323 is continuously sent into condensed water like this, heat steam with regard to constantly occurring continuously being evaporated on the liquid level of evaporimeter 33, just cooling constantly of the liquid of evaporimeter 33 inside like this, whole process of refrigerastion continues like this, has reached saturation state up to right adsorption bed 32b absorption.Meanwhile, the adsorbent of left side adsorbent bed 32a by with the continual heat exchange of hot-air after, originally adsorbed adsorbent also all desorbs (desorption) and by with the cold air heat exchange after, the adsorbent temperature of left adsorption bed 32a also drops to normally.So far domestic solar absorption type central air-conditioning has just been finished from being adsorbed to the one-period of refrigeration.
And then two adsorbent beds begin mutual switching, originally absorption become desorption, originally desorption becomes absorption.The cycle period of a new round begins immediately.The work that whole absorption type central air-conditioning comes to this and goes round and begins again under the heat energy of solar energy drives stops heat supply up to solar energy.
Because solar energy is subjected to the restriction of own nature rule, as round the clock, season etc. geographic latitude influence and the occurring in nature influence of uncertain factor such as sleet rain or shine, cause discontinuity and unstability to solar energy.Be head it off, the present invention has adopted not only simple but also a save way, promptly the evaporimeter 33 of solar energy central air-conditioning is combined by tedge and down-comer and underground storage water cooling pond 5, have heat exchanger coil 51 in the underground storage water cooling pond 5, the liquid in the evaporimeter 33 will enter the hot blast cooling back of underground storage water cooling pond 5 and carry extension set use everywhere by air-conditioning draught fan 7.Like this refrigerant of solar energy is stored in undergroundly, so not only saved the insulation investment of heat energy high temperature storage costliness greatly, and the energy loss of high temperature storage is obviously big a lot of than low temperature.By low tempertaure storage,, can supply air-conditioning as usual like this but store underground refrigerant even do not have the sun in three, five days.
Figure 2 shows that solar energy gas heater structure.Appearance magnetron sputtering one deck high-temperature selective absorber coatings of the copper pipe 11 that heat conductivility is special good.Outside the copper pipe 11 is high-boron-silicon glass pipe 13, and the centre is a vacuum layer 12.The circular net volume 14 that copper pipe 11 inside are rolled into for the special good woven wire of heat conductivility.Wire net volume 14 fills up whole metal tube, and is close to inside pipe wall.Copper pipe top is upper cover 15, and the bottom is a low head 16, has cool air inlet 17 on the low head 16, has hot air outlet 18 on the upper cover 15.After 17 imports of cold air cool air inlet, promptly constantly carry out heat exchange with copper pipe 11 and wire net volume 14, cold air is reached by the technological requirement temperature after, promptly be sent to adsorbent bed 32 and add the interior adsorbent of hott bed.Can be by the several heaters polyphone to increase quantity of hot air, the quantity of heater polyphone is by needs refrigerating capacity decision increase and decrease.When solar energy gas heater 1 carries out solar energy heating, can carry out the optically focused heating at the light collecting heater of application for a patent for invention 02110953.2 disclosed solar full-automatic tracking by the applicant, to reach higher temperature and efficiency of utilization.
Relevant whole temperature, pressure, sensor, it is that mature technology is also no longer repeated here that its operation sequence of the switch of magnetic valve is controlled automatically by computer.
At domestic solar absorption type air-conditioner efficiency deficiency on the low side, main points of the present invention are to raise the efficiency coefficient on the basis of guaranteeing to raise the efficiency as far as possible, promptly improve the cycle period of absorption refrigeration, utilize the heat transfer medium of gas as the absorption type air-conditioning, it is the key that improves absorption type air conditioner refrigerating cycle period, by structure of the present invention, make the adsorption-type solar air-conditioning can reach the efficient of absorption type air-conditioner.
