- an absorption machine comprising at least a first and a second compartment in fluid connection with each other, wherein the first compartment comprises at least one salt selected from the group consisting of LiBr, Lil, LiCI, Nal, and NH 4 I and wherein at least the first compartment comprises Nhb in an amount sufficient to form a liquid together with the at least one salt in the first compartment.
- the first compartment comprises Lil-3H2O and wherein at least the first compartment comprises Nhb in an amount sufficient to form a liquid together with the at least one salt in the first compartment.
- All water which is present or essentially all water, i.e. more than 99wt% of the water in the machine is present in an amount corresponding to hydrate of the at least one salt.
- One example is Lil-3H2O, where the amount of water in the system does not exceed the amount which can be present in the hydride. The amount of water in the system is not allowed to exceed the amount which can form hydrate with the at least one salt with more than 1 wt%.
- all water in the system corresponds to the maximum amount that can be present as hydrate of the at least one salt.
- the salt is present in the first compartment and the ammonia is absorbed by the salt to form a liquid in the first compartment. Ammonia can then be desorbed from the liquid in the first compartment during use of the machine.
- the amount of ammonia varies depending on the salt used and the temperature and pressure. In one example below the mixture of salt Lil-3H2O and ammonia starts to become liquid when about 1 .4 equivalents of ammonia is added, i.e. 1 .4 molecules of Nhb for each molecule of Lil-3H2O.
- Nhb for each molecule of salt such as Lil-3H2O
- 3-4 equivalents of Nhb for each molecule of salt is used.
- more than 2 equivalents of Nhb for each molecule of salt is used.
- more than 1 .5 equivalents of Nhb for each molecule of salt is used.
- an absorption machine comprising at least a first and a second compartment in fluid connection with each other, wherein the first compartment comprises Lil-3H2O and wherein at least the first compartment comprises Nhb in an amount sufficient to form a liquid together with the at least one salt in the first compartment.
- both the first and second compartments are in heat conducting connection with at least one surrounding system adapted to transfer heat to and from said first and second compartments.
- the absorption machine can be used for various purposes including heating and cooling applications as well as heat transfer applications.
- the pressure can be regulated in at least one of said first and second compartments. In yet another embodiment the pressure can be held higher in one of the at least two compartments compared to the other(s). It is conceived that the pressure regulation takes place with known methods such including but not limited to valves, pressure reducing valves and pumps.
- the absorption machine is a chemical heat pump
- a reactor part comprising at least one salt such as Lil-3H2O and arranged to be heated and cooled by an external medium, an evaporator/condenser part containing the portion of the Nhb that exists in a condensed state, and arranged to be heated and cooled by an external medium, and a channel for the vapor phase of Nhb, the channel connecting the reactor part and the evaporator/ condenser part to each other.
- at least one of the first compartment and the second compartment comprises particles.
- at least one of the first compartment and the second compartment comprises particles with a maximum diameter in the range 1 -100 nm.
- At least one of the first compartment and the second compartment comprises two dimensional particles.
- the particles are present in the first compartment only.
- Two dimensional particles include but are not limited to particles of graphene, which extends mainly in two dimensions with the third dimension being only one or a few atom layers.
- the two dimensional particles wherein the size in two dimensions is much larger compared to the thickness can be referred to as flakes.
- the thickness is less than 10 ⁇ 2 or 10 "3 of the lateral size, in further embodiments even less than 10 "4 or 10 "5 .
- at least one of the first compartment and the second compartment comprises particles comprising graphene.
- At least one of the first compartment and the second compartment comprises particles comprising graphene with a size in the interval 0.01 -10 ⁇ , preferably 0.1 -1 ⁇ .
- This size refers to the maximum distance in two dimensions, while the third dimension, the thickness is very thin, only one or a few atoms thick.
- the amount of graphene in relation so salt is 0.001 to 0.1 wt% calculated as the weight of graphene divided by the weight of the salt including the hydrate.
- Advantages of using particles is that the heat conductivity is improved.
- the particles improve the heat transfer from the solution of the at least one salt and/or Nhb to the wall enclosing the compartment. This effect is demonstrated in the example section. It can be seen that there is a notable improvement when graphene is added.
- an absorption machine such as a chemical heat pump using for instance Lil-3H2O + Nhb or another salt can be made smaller and lighter with the same power. Further ⁇ can be improved.
- the vapor pressure of ammonia in the system can be kept relatively high.
- One advantage of using a system where a lot of the water is bound as hydrates to the salt is that the partial pressure of water can be kept very low in the system allowing for efficient use of ammonia in the gas phase instead, which gives advantages for instance a better ⁇ and the possibility to work at different temperatures compared to water.
- a liquid phase can be utilized which also gives advantages in terms of heat conduction etc. In view of this a skilled person realizes that if more water than the amount corresponding to the hydrate of the salt is added, then the function will gradually be less efficient when more water is added.
- the solution of the salt such as Lil-3H2O and Nhb does comprise water, but in this environment water has such a low vapor pressure so that the amount of water following Nhb during heating does not affect the performance to any notable degree. Further this water goes back together with Nhb during discharging. Even if the water can be present both as a hydrate and to some limited extend as free water, the total amount of water does not exceed the amount of water that can be present in the form of hydrate of the at least one salt. Because of the properties of the at least one salt the partial pressure of water in the system will be kept very low.
- Fig 2 discloses a diagram from a discharge where Lil-3H2O is kept at about 60 ° C while stirred with a magnetic stirrer while Nhb is taken up from an insulated compartment.
- the Nhb is a free fluid in the insulated compartment, i.e. a reactor. It can be seen that the cooling capability is high.
- the first compartment of the device comprises Lil-3H2O and Nhb.
- Lil-3H2O is present as soft crystals in pure form.
- Nhb When mixed with Nhb at room temperature Nhb is absorbed by
- Lil-3H2O From experience it is known that when about 1 .4 HN3 molecule per Lil-3H2O has been absorbed the salt starts to become liquid.
- the example is not a complete absorption machine, but instead the reactor part (first compartment) is investigated in a model in order to study the heat transfer capability of the material.
- the setup is described schematically in fig 5 with an amount of liquid Lil-3H2O and Nhb (1 ), a space (2) above the liquid-gas interface, a heat exchanger (3), a spray nozzle (4), a pump (5) for the liquid Lil-3H2O and Nhb, a thermometer (6), a pump (7) for a heat transferring medium, en electrical heater (8) and a thermometer (9) for the heat transferring medium.
- the first compartment comprises a lithium iodide trihydrate ammoniate, formed when Nhb is allowed to react with Lil-3H2O.
- the compartment was filled with 1 kg lithium iodide trihydrate and it was allowed to absorb 3 molecules of ammonia per Lil-3H2O.
- Lil-3H2O was kept in a chamber where the ambient air was pumped out whereafter the desired volume of Nhb was added. No additional water was added in addition to the crystal water in the trihydrate, i.e. the only water present corresponds to the amount that can be presen as a hydride in the salt.
- 3 ammonia molecules were absorbed per lithium iodide unit. This becomes a liquid under ambient pressure and room temperature.
- the liquid is pumped by the spray pump (5) to a spray nozzle (4) over a heat exchanger (3) secondary side. Heat was applied to the heat exchangers primary side from an electrical heater (8) via water circulated by a pump (7).
- the temperature of the applied heat was measured with a first thermometer (9) at the primary side of the heat exchanger.
- the temperature of the lithium iodide trihydrate ammoniate was measured by a thermometer (6) in the flow from the spray pump to the spray nozzle.
- the first compartment comprised lithium iodide trihydrate ammoniate.
- the spray pump and the circulation pump were started and the two temperatures were measured without electrical heating.
- the system was run in a room wtih an ambient temperature of 20 ° C until the two temperatures were identical.
- Graphene was added in a suspension in water to lithium iodide trihydrate.
- the concentration of graphene in the suspension in water was 0.2 wt%.
- the graphene was in the form of thin flakes with a size in the interval 0.1 -1 ⁇ . 1 kg lithium iodide trihydrate was used.
- the water solution comprising graphene was evaporated until lithium iodide trihydrate remained. Water was evaporated and the weight was measured so that the weight corresponded to lithium iodide trihydrade and graphene. Thus all added water was removed.
- This mixture was allowed to absorb 3 molecules of ammonia per Lil-3H2O.
- Lil-3H2O was kept in a chamber where the ambient air was pumped out whereafter the desired volume of Nhb was added. Only an amount of water corresponding to the hydrate was left.
- the temperature of the system in many applications normally will be above 70 ° C, where graphene has a positive influence.
