Description

ANTIFREEZE EVAPORATOR
DESCRIPTION
The present invention refers to an antifreeze evaporator for conditioning systems, which comprises a pipe, wound in a coil, in which the fluid to be cooled flows; inside said pipe there is located a tube bundle through which a coolant fluid, normally consisting of a gas, flows in countercurrent with respect to the fluid to be cooled.
The pipe containing the tube bundle is immersed in a container in which the fluid to be cooled circulates.
Such antifreeze evaporators, which will not be further described because they are per se known, hold the drawback that the distribution of the coolant fluid between the various tubes making up the tube bundle takes place by means of a manifold chamber, connected to which are both the coolant fluid delivery duct and the tubes of the tube bundle, which should be supplied in an uniform manner.
However, because of the kinetic energy of the flow entering the chamber, the jet of the coolant fluid tends to maintain the direction and the size assumed inside the delivery duct, causing an uneven supply to the tubes of the tube bundle - with a consequent reduction in the performance of the assembly — and problems in the control of the flow of the coolant fluid entering the manifold chamber by the thermostatic valve located on the coolant fluid delivery duct.
To overcome these drawbacks, antifreeze evaporator manufacturers adopt empirical and experimental systems which solve the problem only partially.
Object of the present invention is to provide an antifreeze evaporator that is free from the aforementioned limits and drawbacks; this object is achieved by means of an antifreeze evaporator that presents the characterizing features indicated in independent claim 1.
Further characteristics of the invention will be apparent from the dependent claims. The invention will now be described with reference to a purely exemplifying, and therefore non limiting, embodiment thereof, illustrated in the appended figures, wherein:
- Figure 1 shows diagrammatically an antifreeze evaporator comprising coolant fluid distribution means realized in accordance with the invention;
- Figure 2 shows diagrammatically the coolant fluid distribution means realized according to the invention;
- Figure 3 shows diagrammatically the element supporting the tubes of a tube bundle.
In the appended figures, like elements will be identified by the same reference numerals.
The present invention refers to an antifreeze evaporator for conditioning systems comprising at least: a case, at least one pipe (located inside the case) in which a fluid to be cooled flows, at least one tube bundle - positioned inside said pipe and through which a coolant fluid (normally a gas) flows in countercurrent with respect to the fluid to be cooled - and means, positioned between the delivery duct of the coolant fluid and the tubes belonging to the at least one tube bundle, suitable to distribute the coolant fluid evenly between the tubes belonging to the at least one tube bundle.
The distribution means advantageously comprise at least one Venturi-effect canalised flux distributor, having an inlet and a plurality of outlets each of which is connected to one of the tubes of the tube bundle by means of a small tube with a smaller diameter that that of the tube to which it is connected.
Figure 1 shows diagrammatically, in section, an antifreeze evaporator 1 comprising coolant fluid distribution means (5, 6), realized according to the invention, which can be seen better in Figure 2.
As is known, an antifreeze evaporator 1 comprises a case 2 and, inside said case, at least one pipe 3 wound in a coil; in each pipe 3 there flows a fluid to be cooled and there is located a tube bundle 4, comprising a plurality of tubes 8 through which a coolant fluid flows in countercurrent with respect to the fluid to be cooled. The tube bundles 4 containing the tubes 8 are not visible in Figure 1 because they are positioned inside the pipes 3.
In the embodiment shown in Figure 1, the antifreeze evaporator 1 comprises two pipes 3, but antifreeze evaporators 1 comprising only one pipe 3 or three or more pipes 3 are known to the art.
An antifreeze evaporator 1 realized according to the invention comprises distribution means (5, 6) positioned between the delivery duct 9 of the coolant fluid and the tubes 8 of the tube bundles 4 and suitable to distribute the coolant fluid evenly between the tubes 8.
The antifreeze evaporator 1 advantageously further comprises a linear manifold 12, that is, a rectilinear portion of pipe which has a plurality of holes each of which is connected to the end of one of the tubes 8 opposite that connected to the distribution means (5, 6).
The linear manifold 12 allows a better outflow of the coolant fluid but, without departing from the scope of the invention, the tubes 8 can be connected to the outflow duct of the coolant fluid by the same means used for this purpose in an antifreeze evaporator of the prior art.
As is well known to a person skilled in the art, it can happen that the water circulating in the pipes of an antifreeze evaporator is turned to ice, exerting a sufficient pressure on the tubes of the tube bundles contained in said pipes to crush them or, in any case, to damage them, for example by reducing their bore.
In order to safeguard the integrity of the antifreeze evaporator 1, its pipes 3 are advantageously made of an elastic material, preferably rubber, which allows said pipes to adapt their volume to that of the frozen water contained therein, avoiding any risk that the tubes 8 of the tube bundle 4 might be damaged.
This advantageous result has been verified experimentally by the Applicant. Figure 2 shows diagrammatically the coolant fluid distribution means realized according to the invention, which comprise at least one Venturi-effect canalised flux distributor 5 and a plurality of small tubes 6 with a smaller diameter than that of the tubes 8 to be supplied.
The diameter of a small tube 6 is, preferably, 60% of the diameter of the tube 8 to which it is connected and in any case between 50% and 70% of said diameter.
The Venturi-effect canalised flux distributor 5, shown in section in Figure 2, will not be further described because it is well known to a person skilled in the art.
The canalised flux distributor 5 has an inlet 10 connected to the coolant fluid delivery duct 9 and a plurality of outlets 11 , each of which is connected to a tube 8 of the tube bundle 4 by means of one of the small tubes 6; the ends of the tubes 8 connected to the small tubes 6 are carried by a disc-shaped element 7 located at the inlet of the pipe 3.
For the sake of simplicity of the graphic representation, only one of the small tubes 6, of the tubes 8 and of the outlets 11 of the distributor 5 has been identified with the respective reference numeral in Figure 2.
Figure 3 shows diagrammatically the disc-shaped element 7 which supports the ends of the tubes 8 (not visible in Figure 3 because they are concealed by the element 7) which are connected to the small tubes 6 belonging to the coolant fluid distribution means and indicated by dashed lines in Figure 3.
At the centre of the element 7, the hole 13 allowing the fluid to be cooled to leave the pipe 3 can be seen.
For the sake of simplicity of the graphic representation, only three of the small tubes 6 have been identified with the corresponding reference numeral in Figure 3.
The particular embodiment of the cooling fluid distribution means has made it possible to provide a supply system for the tubes 8 of the tube bundle 4 that can advantageously be used in all the gas-air direct expansion exchangers and which ensures the perfect distribution of the coolant fluid to each of the tubes 8 of a bundle 4.
The use of the small tubes 6, positioned at the outlet of the canalised flow distributor 5 and having a smaller diameter than that of the tubes 8 to which they are connected, in fact makes it possible to avoid drops in the pressure of the coolant fluid before its distribution to the tubes 8 of the tube bundles 4.
This ensures that no bubbles of steam, which would cause uncontrolled load losses and uneven distribution of the coolant fluid, are formed.
Without departing from the scope of the invention, a person skilled in the art can make to the antifreeze evaporator previously described all the modifications and the improvements suggested by normal experience and/or by the natural evolution of the art.
