The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
When inorganic acid, alkali, salt are dissolved in water, conventionally all can produce heat release or endothermic effect, this fuel factor can be used for heating or freezing.Based on corrosion and safe reason, it is as received basis that the present invention adopts inorganic salts.When inorganic salts are dissolved in water, be that the hydration heat with water formation hydrated ion is depended on after the lattice energy of salt itself and it are by hydrolytic dissociation in heat absorption or solar heat protection, salt dissociation is destroyed its crystal structure needs heat absorption (being numerically equal to lattice energy), after hydrolytic dissociation, is formed heat release of hydrated ion with water; If lattice energy is greater than hydration heat, when salt dissolves, want absorbing and cooling temperature, will heat release heat up on the contrary.The size of lattice energy and hydration heat depend on the ion that forms salt with amount of charge and ionic radius size.In common inorganic salts, when water-soluble, absorbing and cooling temperature has nitrate, perchlorate, halide, an ammonium salt etc., comprises NH 4cl, NH 4clO 4, NH 4br, NH 4i, NH 4nO 2, NH 4nO 3, NH 4cN, NH 4cNS, AgClO 4, AgNO 2, AgNO 3, LiF, LiClO 43H 2o, NaCl, NaClO 23H 2o, NaClO 3, NaClO 4, NaClO 4h 2o, NaBr2H 2o, NaBrO 3, NaI2H 2o, NaIO 3, NaNO 2, NaNO 3, NaCN2H 2o, NaCNO, NaCNS, KF2H 2o, KCl, KClO 3, KClO 4, KBr, KbrO 3, KI, KIO 3, KNO 2, KNO 3, KCN, KCNO, KCNS, KMnO 4, RbCl, RbClO 3, RbClO 4, RbBr, RbBrO 3, RbI, RbNO 3, CsCl, CsClO 4, CsBr, CsBrO 3, CsI, CsNO 3, (NH 4) 2sO 4, MgSO 47H 2o, Na 2cO 310H 2o, Na 2s 2o 35H 2o, CaCl 26H 2o, CaBr 26H 2o etc.During dissolving, the inorganic salts of heat release have LiCl, LiClH 2o, LiClO 4, LiBr, LiBrH 2o, LiBr2H 2o, LiI, LiIH 2o, LiI2H 2o, LiI3H 2o, LiNO 2, LiNO 2h 2o, NaI, CsF etc.Wherein, NH 4nO 2, NH 4nO 3, NH 4cNS, KClO 3, KClO 4, KNO 3, RbClO 4heat of solution be respectively 300.8kJ/kg, 321.13kJ/kg, 297.23kJ/kg, 337.65kJ/kg, 368.4kJ/kg, 345.1kJ/kg, 306.7kJ/kg.The chlorofluoromethane refrigerant R22 that reduced vapor pressure compression type refrigerating machine is conventional, its refrigerating capacity is 173kJ/kg, needs only as seen choose reasonable, the refrigerating capacity of inorganic salts is better than fluorine Lyons, but its volume is much smaller, and cost is also much lower.For example, 250g CaCl26H 2o is dissolved in 100gH 2o, can make temperature reduce by 23 ℃, and 150g KCNS can make 100gH 2o temperature reduces by 34.5 ℃.In fact, a lot of inorganic salts and combination thereof can refrigeration to below-20 ℃, if carry out circulation temperature lowering, can obtain lower temperature (as-55 ℃, depend on refrigeration working fluid solution and pass the freezing point of cold medium).
Theoretically, as long as there is fuel factor when inorganic salts are dissolved in water, just can regulate for temperature, but practical register also must be considered following condition when selecting suitable inorganic salts as working media: 1, fuel factor is large as much as possible, can save like this consumption and the cost of inorganic salts; 2, solubility is large as much as possible, and energy that like this can consumes least makes its crystallization; 3, own stable chemical nature in operating temperature range, does not decompose or is hydrolyzed, do not blast, also not with container generation chemical reaction; 4, nontoxic, harmless, corrosion-free or few corrosion; 5, thermal capacitance own is as much as possible little.Comprehensive analysis, proper inorganic salts have NH 4nO 3, NH 4cNS, NaNO 3, KNO 3, KCNS, CaCl 26H 2o etc., their relevant parameters is as following table:
Figure BDA0000396444900000051
In the above-mentioned part inorganic salts of enumerating, although some salt is as NaCl heat of solution numeral little, but they also can be used as the thermostatic as received basis of salt dissolution type, and heat of solution also can be used as received basis with the mixture of any two or more salt arbitrary proportions of symbol.Using the benefit of salt-mixture is the quantity that has increased dissolving salt in unit solvent water, and the thermal conversion efficiency of process is improved, and prerequisite is danger (for example, the 41.6g NH that these salt can not react to each other and generate insoluble substance or have blast 4nO 3+ 41.6gNaCl can make 100gH 2o is reduced to-40 ℃ from 0 ℃).In specific design, select any or those several inorganic salts to depend on the intensity of the thermal source that can provide and the cost of selected inorganic salts as received basis.If thermal source is very sufficient, just can select that fuel factor is low, solubility is little but simultaneously cost also low inorganic salts be working medium; If the heat energy that can provide is limited, should select fuel factor and solubility all enough large inorganic salts be as received basis and do not consider its cost.In a word, the leeway of selecting is larger, if be as received basis but select the dissolving and heat absorbing salt with the crystallization water, must carefully control so its heating crystallization temperature or evaporation degree, prevent that inorganic salts from losing the crystallization water when crystallization, otherwise it may produce contrary fuel factor and even cancel each other when being dissolved in water, thereby affects thermoregulation effect.As CaCl 2caCl during aqueous solution heating evaporation 2may lose whole crystallizations water, if be dissolved in water again, will produce two contrary fuel factors: CaCl first 2with 6H 2o is in conjunction with emitting a large amount of heat, then CaCl 26H 2o dissolves and absorbs heat again, and total fuel factor is heat release, so it just can not freeze.On the contrary, for exothermic dissolution salt, must eliminate its crystallization water, but accomplish that this point is comparatively speaking than being easier to.Heating-up temperature can not surpass the heat decomposition temperature of inorganic salts in addition, as nitrate, perchlorate, ammonium salt etc.In addition, in the inorganic salts as received basis, can add some functional additives, prevent blast, caking, foam-expelling of salt etc.
In principle, each elementary cell should have a blower fan, but elementary cell is two or more parallel operations always, therefore two or more elementary cells can share a blower fan in some cases, by pipeline valve, regulate the ventilation of each elementary cell, do like this and can further save cost.
In cold especially area, if aforesaid way still can not meet and heat requirement, inorganic salts can be changed into exothermic dissolution salt or some alkali as LiOH, NaOH, KOH, RbOH, CsOH etc. by dissolving and heat absorbing salt.Because their fuel factor can be larger than conventional dissolving and heat absorbing salt, and etching problem ratio is easier to process, if but will take measures to prevent its carbonation with alkali.When they are dissolved in water, emit a large amount of heat, during evaporative crystallization, absorb heat, so take the register that they are medium, can not freeze, it has in fact just stored the heat content of heat medium, and discharges when needed again.This be extraordinary energy-saving scheme to heat supply with needing hot nonsynchronous place.
Based on above-mentioned principle, the present invention has made a kind of salt dissolution type temperature-adjusting device, its structure is as Fig. 1, shown in Fig. 2, it comprises register, register comprises moist closet 1, moist closet 1 is made (as metal material surface spraying polystyrene foam by heat-barrier material, the heat-barrier materials such as polyaminoresin foam), moist closet 1 is connected heating pipe 7 and the refrigerator pipe 11 that stretch out in the oriented external world, in moist closet 1, be provided with heat exchanger 2, in heat exchanger 2, be placed with inorganic salts, heat exchanger 2 is connected the filler pipe road 6 that is useful on input running water, for discharging the steam discharge line 10 of steam, in heat exchanger 2, be provided with heat exchanger tube (not marking in figure), heat exchanger tube one end with for inputting the water back 5 of heat medium 16, be connected, the other end of heat exchanger tube is connected with the discharge duct 9 of discharging heat medium, described moist closet 1 inwall is provided with the air-supply arrangement that heat exchanger 2 is carried air.

In the present invention, salt dissolution type temperature-adjusting device utilizes heat energy to carry out work, but it does not consume heat energy at work, and it just utilizes heat energy to carry out the separated of cold-peace heat and shifted.The refrigeration of take is example, and its energy conversion relation is △ H input=△ H output-Q refrigerating capacity, that is to say, owing to having produced cold, according to law of conservation of energy, the heat of device output is greater than the heat of input, and the heat of its output (water vapour) still can be used as energy utilization.Therefore if seal in salt dissolution type temperature-adjusting device in existing water vapour loop, will be, very economical.
The designed salt dissolution type of the present invention temperature-adjusting device is closely similar with LiBr Absorption Refrigerator on the energy is used, these two kinds of devices all will utilize heat energy to carry out heating evaporation to inorganic salt solution, difference is, the former generally will be evaporated to crystallization inorganic salt solution, and the latter is evaporation and concentration.But in operation principle, these two kinds of devices are but essentially different, the former is the heat of solution that utilizes inorganic salts, and latter is the heat of gasification refrigeration of utilizing water, and absorption dilution and the evaporation and concentration of salting liquid are supporting process, obviously, the latter is more huge and complicated.Comparatively speaking, the thermostatic advantage of salt dissolution type is as follows:
1, salt dissolution type temperature-adjusting device does not need negative-pressure operation, therefore less demanding to the air-tightness of equipment, manufactures more convenient, cheaply, and working service is more easy to be reliable;
2,, because as received basis does not circulate, quantity and the energy resource consumption of circulating pump have been reduced;
3, salt dissolution type temperature-adjusting device has a lot of inorganic salts to utilize, and their cost is all low than LiBr;
4, salt dissolution type temperature-adjusting device is a kind of accumulation energy type device, and it can carry out at times to the manufacture of cold air, hot gas and supply, so its utilizable energy is wider, as long as the temperature of thermal source is greater than 100 ℃, gets final product work;
5, salt dissolution type temperature-adjusting device is consumption of calorie not in when refrigeration, and its can utilize by the larger cold of output ratio input heat, and LiBr Absorption Refrigerator is not accomplished this point;
6, salt dissolution type temperature-adjusting device is according to using the difference of inorganic salts temperature can be turned down to-55 ℃, therefore can make refrigerator and refrigerator, and the cooling of LiBr Absorption Refrigerator is minimum in theory, can only arrive 0 ℃, otherwise the water as cold-producing medium will freeze and cannot work, and in fact reach 0 ℃, is also impossible;
7, due to LiBr Absorption Refrigerator complex structure, bulky, it is made to midget plant is very uneconomic, therefore be all to make Large Central Air Conditioning System conventionally, responsiveness is poor, and salt dissolution type temperature-adjusting device can be done very littlely, can immediately freeze, range of application is wider, for example can be for automobile and family;
8, salt dissolution type temperature-adjusting device can be made huge device ，He steam power plant coupling, realize heat, electricity, cold coproduction alliance (can make full use of existing urban heating network), and LiBr Absorption Refrigerator is difficult to accomplish this point.
Compare with traditional steam compressing air conditioner, salt dissolution type temperature-adjusting device has the following advantages:
1, do not destroy atmospheric ozone layer, there is no environmental pollution;
2, moving component is few, and operating noise is lower, longer service life;
3, more convenient and safety is installed;
4,, because salt dissolution type temperature-adjusting device be take and utilized heat energy as main, and in order to being that main traditional air-conditioning is different with electric energy, it utilizes the efficiency of energy is that traditional air-conditioning can not be compared, and can adopt various low-grade energy.
The automobile-used salt dissolution type of embodiment mono-air-conditioning:
Almost each automobile all needs to install an air-conditioner.Existing on-board air conditioner is all traditional steam compressing air conditioner, and its need of work is driven by automobile engine, or need to increase a special-purpose refrigeration engine, just need to consume extra energy, increase fuel consumption, increased noise, also increased discharge amount of exhaust gas.The chemical energy energy transform into heat energy that automobile engine contains gasoline, diesel oil, convert the needed kinetic energy of automobile to again, but owing to being subject to the restriction of heat engine Carnot cycle and automobilism is instable affects, the hot merit conversion efficiency of engine on average only has 15%～20% left and right, that is to say, the heat that fuel oil produces has considerable part (30～40%) all by motor vehicle exhaust emission, to lose, so export at generator tail gas, temperature can reach more than 300 ℃, sometimes even up to 900 ℃.Therefore, if this part heat is used for adding hot brine solution, make it evaporative crystallization, not only can save fuel oil, also can reduce discharge amount of exhaust gas.
Fig. 3 be salt dissolution type temperature-adjusting device for an example of automobile, it is formed in parallel by 2 elementary cell A and B, and to adopt dissolving and heat absorbing salt be as received basis.The water back 5 of elementary cell A and B, discharge duct 9, filler pipe road 6, steam discharge line 10 are all parallel to total pipeline separately, all load onto magnetic valve asynchronous to guarantee the duty of A, B at every arm near house steward's place.The refrigeration in car of take is example, and unit A is in refrigeration constantly to suppose certain, and unit B is heating, and at this moment, magnetic valve 23,33,25,32,36,22,28,30 is in opening, and magnetic valve 24,34,26,35,31,21,27,29 is in closed condition; The heat exchanger that water in water tank 41 is got in unit A through valve 25 by pump 42 freezes, and cold wind is transported in car through valve 23,33; Simultaneously, generator tail gas is delivered to the heat exchanger of unit B through valve 22, then outside valve 28 is discharged cars, the steam that in B, heat exchanger produces is transported to heat exchanger 43 through valve 30 and sends into water tank 41 after cooling, recycle, the hot-air producing in B is discharged outside car through valve 32,36.When A completes refrigeration, B complete crystallization and cooling after, magnetic valve 23,33,25,32,36,22,28,30 cuts out, magnetic valve 24,34,26,35,31,21,27,29 is opened simultaneously, unit A heats and discharges outside car, unit B refrigeration is sent in car, like this, has just guaranteed continuous cooling in car.
In addition, because the heating load of motor exhaust is very large, may be more than the required heat of evaporite solution, at motor exhaust, input a house steward side road arm in parallel and magnetic valve 37 is installed, when one of A and B freeze and motor exhaust transfer valve that another one is closed it while having completed evaporative crystallization, Open valve 37, allows motor exhaust discharge thus simultaneously.The work of the switch of all magnetic valves, water pump and fan can be controlled by a program controller, and by regulating the power of water pump and fan to regulate the amplitude of cooling.
If need to heat, only need magnetic valve 33,34,35,36 be set to contrary with cooling condition.For for simplicity, also can in parallel arm, settle reversal valve to replace the magnetic valve of settling separately.
If use CaCl26H2O is working media, automobile-used salt dissolution type air-conditioning also has another pyrogenicity mode, the heat that the heat of transformation (170kJ/kg) that the crystallization water that utilizes CaCl26H2O CaCl2 after being warmed up to its fusing point (approximately 27 ℃) to be dissolved in himself produces comes store automobiles tail gas to produce, then pyrogenicity when low temperature.In this case, the structure of aircondition does not need to change, and only needs vehicle exhaust that solid-state CaCl26H2O is heated to fusing and dissolves, do not need to start water controller part, as long as environment inside car temperature is lower than 27 ℃, it is quantity of heat given up automatically just, more simple in control like this.As mentioned above, being heated to higher temperature, even to lose the crystallization water be also feasible, but at this moment need to start moisturizing device.
Except making full use of the waste heat of vehicle exhaust, automobile-used salt dissolution type air-conditioning also has an outstanding advantage, is exactly no matter to be pyrogenicity or refrigeration, it can be energy storage type, be automobile during stagnation of movement, even if do not start the engine, also can provide comfortable environment inside car.
Similarly device can be used for manufacturing refrigerating transport vehicle, fish freezing chamber, beeliner air-conditioning, also can be arranged on aircraft, steamer and all has the place of Industrial Boiler and industrial combustion stove (converter of using as metallurgical, machinery, building materials industry, gas furnace etc.), civil boiler, for industrial refrigeration or life refrigeration.
Execute example two family expenses or commercial discrete air-conditioning:
The implication of " discrete " refers to that air-conditioning has independently heating system herein.
Salt dissolution type family expenses or commercial discrete air-conditioning are consistent with the essential structure of car air-conditioner, just the difference to some extent in pipe-line system due to the difference of concrete applied environment and thermal source:
The first, family expenses or commercial discrete air-conditioning do not need special-purpose storage tank, directly use running water; In addition, the water vapour that salting liquid evaporation produces does not need after cooling to recycle, but is transported to water heater as bathing use, has saved like this energy.
The second, the heat medium of family expenses or business air conditioner circulates, but heating energy source be take and adopted industrial waste gas and solar energy as good.
Three, in certain elementary cell of domestic air conditioning during in cooling condition, refrigerator pipe is other starts an arm, and guides to the container of an insulation, and this container has been exactly refrigerator so.
As shown in Figure 4, the workflow of salt dissolution type family expenses or commercial discrete air-conditioning is: running water introduces elementary cell A by valve 44 or B is used for dissolve inorganic salts, and the steam that evaporation inorganic salt solution produces enters water heater 53 for bathing by valve 29 or 30; The other also arm of cold air house steward is guided to refrigerator 46 by valve 45, opens if desired valve 45 and just can make refrigerator 46 work; The 49th, parabolic light focusing type solar heater, during work, valve 47,51 is opened, and valve 48,52 is closed, and heat transfer medium is delivered to elementary cell A or B for evaporite solution and is circulated at pipeline by circulating pump 51 after 49 heating; If valve 47,51 is closed, valve 48,52 is opened, and the cold medium of biography in refrigerator 50 is through circulating pump 51 circulations, and refrigerator 50 just can be used for freezing.
So it is climate comfort merely that family expenses or business air conditioner have more than, but as a system, play the effect of water heater and refrigerator simultaneously.
Embodiment tri-:
In gross generation in the world, there is a sizable part for traditional steam compressing air conditioner now.From energy utilization efficiency, this mode of utilizing is very uneconomic, because it has experienced a plurality of transfer processes such as heat energy → mechanical energy → electric energy → mechanical energy → heat energy, utilization ratio progressively reduces, particularly first transfer process heat energy → mechanical energy, as previously mentioned, is subject to the restriction of heat engine Carnot cycle, its hot merit conversion efficiency only has 40% left and right, and therefore total conversion efficiency is low-down.
In large-scale commercial applications generation mode now, water power only accounts for small part, thermoelectricity and nuclear power account for major part, and they are all that heating water produces superheated vapour, then utilize superheated vapour to promote turbo-generator generating, but wherein only have small part heat energy to be transformed into electric energy, theoretically, remaining heat energy is utilizable, as freezed with heat pump techniques, but its technical and economic feasibility has problems and there is no an example application, and therefore a large amount of heat energy is not actually and is utilized.
Salt dissolution type temperature-adjusting device can utilize this part heat energy easily, and its power conversion mode is simple heat energy → heat energy, can have very high energy utilization efficiency (in principle, salt dissolution type temperature-adjusting device has just stored heat, rather than consumption of calorie; For a salt dissolution type temperature-adjusting device for lowering the temperature, because it wants the heat in absorbing environmental in kind of refrigeration cycle, so the total amount of heat of its output is greater than the heat of input, and the heat energy of this part output remains utilizable, as return to boiler, enter power generation cycle next time.If powerful salt dissolution type temperature-adjusting device has been installed in steam power plant's (comprising thermal power plant and nuclear power plant), traditional vapor compression formula air-conditioning will save the huge demand of electric energy so, even can carry out zero cost operation.
Under normal condition, because always there is stable heat energy output in steam power plant, there is no need to adopt the mode of chemical energy storage to carry out hyperthermic treatment, the salt dissolution type temperature-adjusting device that is therefore arranged on steam power plant's (comprising thermal power plant and nuclear power plant) can only be considered refrigeration.
The same with embodiment mono-, the salt dissolution type temperature-adjusting device of steam power plant also can adopt burnt gas to carry out heating evaporation salting liquid, its workflow as shown in Figure 5, similar with the flow chart of car air-conditioner, just the scale of device becomes huge, and the hot-air producing during device work does not need to utilize, but by valve 31 or 32 discharges.
In some cases, burnt gas may differ and meet surely the huge power demand of salt dissolution type temperature-adjusting device, and nuclear power plant is not had to burnt gas, therefore can directly utilize the low temperature and low pressure water vapor of discharging from steam turbine generator to carry out heating evaporation salting liquid.As everyone knows, in existing pyroelectric technology, no matter be thermoelectricity or nuclear power, the low temperature and low pressure water vapor of discharging from steam turbine generator all will be sent to boiler heating again, recycle after a condenser, and the thermostatic evaporation process of salt dissolution type just can play the effect of condensation, be equivalent to a condenser, therefore, the salt dissolution type temperature-adjusting device of connecting in existing steam power plant steam circulation on the work of steam turbine generator without any impact.In such a integrated system, the thermostatic workflow of salt dissolution type as shown in Figure 6: the 52nd, steam turbine generator, the 53rd, boiler or nuclear reactor heating system are connected into salt dissolution type temperature-adjusting device in their vapor recycle pipeline.The low temperature and low pressure water vapor of discharging from steam turbine generator 52, through circulating pump 51 input elementary cell A or B, for evaporative crystallization salting liquid, then transports to boiler or 53 heating of nuclear reactor heating system, then transports to steam turbine generator 52 generatings, completes a circulation.The externally heat supply of water vapour producing when elementary cell A or B evaporation, also can input other elementary cell and realize multiple-effect evaporation, and the hot-air producing during their work is by valve 31 or 32 discharges.
The cold air that the salt dissolution type temperature-adjusting device of steam power plant is produced is transported to community or commercial center terminal use through utilidor, also can be for the manufacture of various types of freezers, artificial rink, artificial ski field etc. as supermarket, hotel, office building, residential building etc.
From above embodiment, can see, the thermostatic energy-saving effect of salt dissolution type is remarkable, simultaneously to reducing greenhouse gases CO 2discharge capacity and control atmosphere pollution and be also significant.
