Definitions

  • the present invention relates to air treatment systems which establish an outgoing air circulation and an incoming air circulation with respect to the enclosures of application, utilizing the outgoing air temperature to thermally adapt the incoming air, proposing a tube with particular structural features which determines in a single-component structural assembly a plurality of channels through which the separate circulation of two airflows under optimal conditions for heat exchange between them can be established, making the installation of the mentioned air treatment systems easier with conditions providing enormous system efficiency.
  • heating means such as unit heaters, air heaters or heating installations
  • cooling means such as air conditioning installations, or mixed systems, such as heat pumps that allow both heating and cooling, as needed, are commonly used to maintain thermal comfort conditions inside enclosures.
  • Said systems use a heat recovery unit having a heat exchanger in which two air circulation flows corresponding to the outgoing air and to the incoming air in the enclosures of application are connected to but not mixed with one another.
  • Conventional heat exchangers used for that function consist of a plurality of tubes that are arranged between perforated end plates acting as a support for the tubes, that assembly being incorporated inside a tubular shell, such that an air circulation flow is made to pass through the interior of the tubes arranged between the end plates and another air circulation flow passing through the exterior of the tubes, in contact with said tubes, is made to pass through the interior of the tubular shell, but without mixing with the air circulating through the interior thereof.
  • Said structuring is effective for heat exchange between the airflows passing through the interior and through the exterior of the tubes of the exchanger, but it is a very expensive construction because each tube component must be individually connected to the end plates in order to form the heat exchanger.
  • the invention proposes a tube developed with structural features determining a very advantageous constructive embodiment with a configuration that is perfectly suitable for establishing independent air circulation flows with heat transfer therebetween.
  • This tube object of the invention consists of a structure formed by a single-component structure determining a plurality of parallel tubular shapes which are connected to a side plate laterally closing said shapes and acting as a support for same, there being intermediate spaces constituting zones through which an airflow can circulate along the length in contact with the mentioned tubular shapes between the mentioned tubular shapes.
  • a tube is thereby obtained which defines along the length thereof tubular shapes through which a first airflow can circulate, and between said tubular shapes spaces through which a second airflow can circulate without mixing with the first airflow but in contact with the tubular shapes through which said first airflow circulates, such that heat transmission which allows heat transfer between both airflows, from the hotter to the colder airflow, occurs through the walls of the tubular shapes.
  • the structuring of the tube allows the walls of the tubular shapes of the tube to have a very small thickness, which favors heat transfer between the first airflow circulating through the interior of said tubular shapes and the second airflow circulating through the exterior of said shapes along the tubular assembly. Furthermore, the tubular shapes extending according to the longitudinal direction of the tube and according to transverse lines of the section thereof have a surface with a large dimension, which also favors heat transmission between the interior and the exterior of said shapes.
  • the tube is furthermore formed by a single-component structural assembly having a uniform section along the length thereof, which allows manufacturing same continuously by extrusion, for cutting the longitudinal measurement required in each case, such that the single-component assembly of the tube greatly simplifies assembling the constructive formation of the heat exchangers of application since only a single tubular element, and not a plurality of independent tubes like in the structural solutions of conventional heat exchangers, is to be handled.
  • Said tube object of the invention therefore has features that are very advantageous for forming heat exchangers for which it is intended, being novel and preferred with respect to conventional solutions for forming heat exchangers with independent tubes that must be incorporated individually when assembling said exchangers.
  • the object of the invention relates to a tube intended for forming heat exchangers, particularly those used in heat recovery units of air treatment installations or the like, through which air circulation flows that influence but do not mix with one another are established, such that heat exchange occurs between them.
  • the tube according to the invention consists of a single-component structural assembly (1) formed by a plurality of tubular shapes (2) which are arranged parallel to one another and laterally connected to a plate (3) acting as a support, connecting all the tubular shapes (2), said tubular shapes (2) being arranged parallel to one another, separated by intermediate spaces (4).
  • the plate (3) partially surrounds the structural assembly (1) on one side, according to the distribution of the tubular shapes (2) which are closed on that side by means of said plate (3) and on the other side by the proper end of the tubular shapes (2).
  • said structural assembly (1) of the tube is uniform along the length thereof, having the same section along the entire length, which allows it to be manufactured continuously by extrusion, in order to cut longitudinal pieces into the measurement required for each application.
  • the tubular shapes (2) can, for example, but in a non-limiting manner, have a narrow rectangular section, said tubular shapes (2) being arranged according to the longitudinal direction of the tube, extending laterally in the transverse direction of the section thereof; and for them to have a suitable strength structurally speaking, said tubular shapes (2) have reinforcement partitions (5) extending in the longitudinal direction internally between their walls, which reinforcement partitions (5) divide the interior of the mentioned tubular shapes (2) into sections forming longitudinal channels, the number of which may vary depending on the dimension of each of said tubular shapes (2) in the lateral extension thereof in the width of the structural assembly (1).
  • the shape and distribution of the tubular shapes (2) can vary, determining different cross-section configurations of the structural assembly (1) of the tube, according to the shape required in each application, for example a circular shape such as the embodiment of Figures 1 and 2 , a square shape such as the embodiment of Figures 3 and 4 , or a semicircular shape such as the embodiment of Figure 9 , without these configurations being limiting, since it can be any round, polygonal or mixtilinear configuration.
