Definitions
- the invention relates to an indirect refrigerating apparatus refrigerating machine.
- NH3 and dispose of an economizer used device when the external condenser side fluid temperature is lower than the evaporator side.
- FIG. 1 is a diagram of an installation according to the invention
- FIG. 3 is a variant in cold production by solid machine / gas powered by solar energy.
- - Figure 4 is a variant for compression systems.
- FIG. 5 is a sectional view of a component of the invention.
- FIG. 6 is a variant of the invention for a chemical reaction machine comprising two salts.
- FIG. 7 is a variant of the invention for a refrigeration machine with chemical reaction comprising three salts as described for example in Lebrun / Mauran / Spinner patent application No. 8913913
- Figure 8 is a variant of Figure 1 for an installation comprising two reactors allowing continuous operation.
- Figure 9 is a variant of Figure 6 for an installation with two salts and continuous operation.
- a condenser 17 is placed in the tank 14 containing the liquid 15. This reservoir is heat-insulated outwardly (or inwardly) by an insulating material 16, and is related to the chemical reactor R through a pipe 10, to a condenser 11, and a pipe 13.
- the liquid 15 (NH3) vaporizes thanks to the heat brought at low temperature by the condenser 17.
- the vapor 24 formed is then sucked by the reactor R During this phase the intermediate fluid which has condensed in 17 is directed into the reservoir 18 then gravitatively goes into the evaporator 21 via the regulation valve 20 whose role is to regulate the temperature of the enclosure CF refrigerated.
- the intermediate fluid eg HFC
- the flow of the intermediate fluid is effected under gravity due to the difference of density between liquid and vapor.
- Self-sealing or sealable fittings 19 and 23 allow easy assembly and disassembly of the assembly.
- FIG. 2 represents a variant of the invention in which the production of cold is ensured by a water evaporator 27 comprising as exchanger 28 playing the same role as the evaporator 21 of FIG. 1.
- Figure 3 is an alternative embodiment for the application in cold production from a solar energy source, the reactor R exchanger may also be double as in Figure 2.
- Figure 4 shows the application from the device according to the invention to a compression cold production installation.
- a conventional refrigeration circuit comprises a compressor 40, a condenser 43, a pressure reducer 46, an evaporator 41.
- the fluid to be cooled enters EF and leaves SF from l ' intermediate evaporator 48.
- This comprises an exchanger 49 in which the intermediate fluid evaporates which will then condense in the exchanger 47, the liquid formed is stored in the reserve 59 then returns to 49.
- a similar circuit is placed on the condenser circuit 43 with a condenser 42, a reserve 58 and an exchanger 44.
- FIG. 5 shows a detail of the Figure 1 container according to the invention.
- the heat exchanger 17 ( Figure 1) consists of tubes filled horizontal 52 of fins 51 (or needles as in the case of spin-fin exchangers). The heat exchanger is placed in the lower part of the tank 14 in order to be always bathed by the liquid 15. The intermediate transfer fluid phase change penetrates G in the upper part of the exchanger and in the liquid L.
- the spring 6 shows an example of application of the invention in a chemical refrigerating machine in two salts.
- the cold produced at the exchanger 65 serves as regeneration heat for the reactor R2.
- a second AC circuit comprising two other reactors as those of the first circuit, enable a continuous production of cold at the evaporator 65.
- Figure 7 shows an example of application of the invention for a chemical refrigerating machine circuit three salts.
- the evaporator 65 ensures continuous cold production by ensuring the successive regeneration of the reactors RI and R2 which contain a salt at a low level of regeneration temperature such as BaC12 / NH3.
- R4 in regeneration phase (which contains a salt such as NiC12 / NH3) the heating exchanger 64 transfers its heat to the heat exchanger 72 which desorbs thereby RI to R4.
- the cold produced in CF by vaporization of the intermediate fluid will regenerate the reactor R2 which will then be desorbed towards R3.
- the reaction heat of the reactors RI and R3 will be removed according to the same principle in the condenser 73 after opening the valve 80.
- the reactor RI is regenerated from the production of cold in the R2 reactor 65.
- the heat of reaction is discharged to the condenser 73, the heat exchanger 71 is then overheated relative to the equilibrium temperature of liquid / vapor through cold production fluid, thereby preventing any flow between 71 and 65.
- FIG. 8 represents a variant of FIG. 1 in which the installation comprises two independent chemical reactor circuits Ra and Rb, each comprising its own condenser 11a and 11b and its own reservoir 14a and 14b. The two reactors are regenerated alternately by the heating means 64. both reactors have a common cooler 12.
- a cooling in exchanger 91 serves to cool the exiting a condenser fluid with the cold vapor exiting the reservoir of the other two circuit.Les exchangers 17a and 17b allow the cold to be transmitted from the tank to the evaporator 21, the thermal diode effect preventing transfers if one of the reactor circuits is in the regeneration phase.
- Figure 9 shows a variant of Figure 6 for ensuring a continuous production of cold for an installation with two salts.
- the RI and R2 reactors are grouped in the same body in this figure, namely Rla / R2a and Rlb / R2b respectively.
- the same cooler 61 removes the heat released during the chemical reactions by the same superimposed heat pipe process.
- the alternating heating of the two reactors is provided by the exchanger 64 which can be either a boiler or some other source of heat at a sufficient temperature.
- the control valve 20 shown in Figures 1 to 9 may be either a thermostatic valve controls the temperature of the cold environment, a pressure valve which closes the circuit if the pressure of the latter falls below a threshold, or another electromagnetic valve controlled by the temperature of the medium to be cooled, for example.
- the invention is not limited of course to the production of cold by thermochemical machine, it can also be applied to adsorption machines using for example the zeolite / water or activated carbon / methanol pairs, as well as to refrigeration machines with compression or absorption such as NH3 H2O (in this case the co ⁇ pression circuit as shown in Figure 4 is replaced by an absorption circuit).
- the invention is applicable in particular to the cooling of refrigerated trucks, to the air conditioning of all types of motor vehicles, to heating, to the production of hot water, to the production of solar cold, to chilled water plants.
- the air exchangers may be natural convection or forced circulation using a fan.
