If without other definition, any term and scientific terminology used herein are intended to have fields of the present invention
The normally understood implication of technical staff.
For usually utilizing NH3It is that when the mix is to be heated, water follows with problem for the absorption machine of both water
NH3, and follow NH3Water form problem.In the present invention, this is by using absorption NH3Salt such as LiI3H2O is solved
Certainly, wherein water is attached to salt as hydrate.Describe in Fig. 1 and be used for LiI3H2O+NH3Vapour pressure, and as it is visible can
Realize considerable Δ T.In the NH of 4M3Under, Δ T is close to 70 DEG C, and in the NH of 1.77M3Under, Δ T is close to 120 DEG C.
Salt such as LiI3H2O and NH3Solution include water, but in such circumstances, water has so low vapour pressure, makes
Obtain and follow NH during heating3The amount of water performance is not influenced with any significant degree.In addition, this water during discharge with NH3
Return together.Hydrate presence is can not only be used for even if water on certain limited extent as free water can also to exist, but water is total
Amount be no more than can water existing in the form of the hydrate of at least one salt amount.Due to the characteristic of at least one salt, system
The partial pressure of middle water will keep very low.
Temperature stability test, which has provided 200 DEG C of temperature, does not influence the stability of system.
Fig. 2 discloses the figure for carrying out self-discharging, wherein by LiI3H2O is maintained at about 60 DEG C, while is carried out with magnetic stirrer
Stirring, while will be from NH3Extracted out in insulation compartment.NH3It is the free fluid in insulation compartment (i.e. reactor).It can be seen that cooling energy
Power is high.
Because NH3It is miscible with water, it is envisaged that NH3In some can with from LiI3H2The accessible H of O2O molecules
Form solution.

In, wherein pumping out surrounding air, then add the NH of intended volume3.In addition to the crystallization water in trihydrate, volume is not added with
Outer water, i.e., the water only deposited corresponds to can be in salt as amount existing for hydride.In this embodiment, each lithium iodide unit
Absorb 3 amino molecules.This becomes liquid in environmental pressure and at room temperature.Liquid is pumped into heat exchanger (3) pair by atomizing pump (5)
Spray nozzle (4) on side.Heat is applied to the master of heat exchanger via the water by pump (7) circulation from electric heater (8).
The hot temperature applied is measured with the first thermometer (9) at the master of heat exchanger.Three water of lithium iodide
The temperature for closing ammonate is measured by thermometer (6) in the flowing from atomizing pump to spray nozzle.
In the first experiment, first compartment includes lithium iodide three and is hydrated ammonate.Startup atomizing pump and circulating pump, and
Do not have it is electrically heated in the case of measure two temperature.System is run in the room that environment temperature is 20 DEG C, until two temperature
It is identical.
When two different temperature are identical with time stepping method and stablize, electrical heating is opened.Gained can be found out in figure 3
Temperature.It can be seen that the temperature difference after 3 minutes is about 5 DEG C, and the temperature difference after 9 minutes is about 7 DEG C.It can be seen that the transmission of heat is with temperature
Rise and be damaged.
Example 2
Repeat to test with different contents in compartment.Graphene is added to system, to study it to heat-transfer character
Influence.
Graphene is added to lithium iodide trihydrate in water slurry.The concentration of graphene in water slurry is
0.2 weight %.Graphene is in the form of thin slice of the size in 0.1 μm to 1 μm section.Use 1kg lithium iodide trihydrates.So
Afterwards, the aqueous solution evaporation comprising graphene is made until remaining lithium iodide trihydrate.Evaporate the water, and measure weight so that
Weight corresponds to lithium iodide trihydrate and graphene.Therefore, the water of all additions is removed.This mixture allows each LiI
3H2O absorbs the ammonia of 3 molecules.By LiI3H2O is kept in the chamber, wherein pumping out surrounding air, then adds intended volume
NH3.The amount of the only remaining water for corresponding to hydrate.
The experiment in embodiment 1 is repeated by temperature stabilization and heating.
In Fig. 4 as it can be seen that the temperature difference after 3 minutes remains as about 5 DEG C, but the temperature difference after 9 minutes remains as about 5 DEG C.It can obtain
Go out conclusion, graphene influences the heat transfer of material in a positive manner at high temperature.
It is contemplated that the temperature of the system in many applications will be normally higher than 70 DEG C, wherein graphene has active influence.
The heat-transfer capability about 30% of material can be improved from these data estimation graphene.
As long as combination not contradiction, in the case where not departing from inventive concept, it is all above it is expected alternative embodiment or
The part of embodiment can be freely combined.
Reading specification and during example, further feature of the invention and purposes and its it is associated the advantages of for this area
It will be apparent for technical staff.
It should be understood that the invention is not restricted to specific embodiment depicted herein.Because the scope of the present invention is only by appended power
Profit requires and its equivalents limitation, so providing the purpose that these embodiments are in order at explanation, it is not intended to the limitation present invention
