Definitions

  • This invention relates to an arrangement for exchanging heat according to the preamble of claim 1 and to an air climatiser that includes said arrangement.
  • Such an arrangement is known from US-A-6 338 256 .
  • Heat exchangers are known, such as the type called radiators, in which the fluid to be cooled is passed through a plurality of low-flow conduits that are in contact with a current of air generated by a jet fan that projects the current onto the aforesaid conduits.
  • the fluid conduits used in a radiator can be plates or pipes that usually have exterior fins or other elements for increasing the heat-dissipation surface area.
  • Patent JP59142379 discloses a heat exchanger whose heat-exchange efficiency is increased by attaching to the exterior surface of the conduit that carries the fluid a thin plate bent into a star shape, leaving the front side and the rear part of said plate open.
  • the heat exchangers described have the disadvantage of their heat-exchange efficiency being in practice very limited, making them useful only when the fluid-temperature jumps sought are small (as in the case of the heat exchangers used to cool fluids from engines and/or components that give off heat).
  • the objective of the present invention is to resolve the disadvantages mentioned above by developing an arrangement for exchanging heat and a climatiser based on the aforesaid arrangement, which have very low energy consumption, are very simple and very highly effective.
  • an arrangement for exchanging heat is provided according to claim 1.
  • the arrangement for exchanging heat of the present invention has a very high heat-exchange efficiency, basically due to the fact that the forced-impulsion piping of gas enables a very significant increase both of the time devoted to heat-exchange between the gas and the fluid as well as the gas pressure and contact surface area of said gas on the fluid conduits mounted inside the forced-impulsion piping.
  • the length or route of the piping conduit and, therefore, also of the fluid conduits inside it can be considerable, being limited solely by the power of the aspirator connected to the aforesaid gas pipe.
  • the length of the fluid conduits and, therefore, the contact time between the gas and fluid conduits can be very considerable, and so it can take up or lose a larger amount of heat.
  • conduit is taken to mean a channel or tubular element that serves as a passageway or outlet for a fluid, gas or liquid.
  • said channel or tubular element will have projecting elements (such as fins) on its outer surface in order to facilitate the exchange of heat.
  • fluid will be taken to mean a liquid or gas capable of exchanging heat with the gas that is circulating through the second set of pipes of the exchanger.
  • Aspirator is taken to mean any machine or appliance that uses vacuum to draw out gases.
  • the gas of the arrangement for exchanging heat is air, since it is an easy and safe fluid to handle and, advantageously, said fluid is a liquid that circulates through the interior of said first conduit.
  • the gas of the exchanger can, instead of air, be an inert gas with refrigerating power, such as nitrogen.
  • the exchanger of the present invention uses air as a gas exchanger, it has the advantage of permitting the fluid in the first conduit to be heated or cooled and, at the same time, obtaining ducted cold or warm air that can be used for climatising premises.
  • the equipment can thus find a dual use in industry or in households; as heat exchanger and as climatiser (heating/cooling) of premises.
  • the liquid fluid of the exchanger is water, with said water being for industrial or domestic use.
  • Water has the advantage of being an innocuous and easily obtained fluid.
  • the contact or heat-exchange time between the gas and the fluid conduits can be enormously increased without the space occupied by the exchanger increasing significantly.
  • the enclosed chamber facilitates the single-support installation of several independent conduit circuits that can share the same gas inlet and outlet and, therefore, a single aspirator.
  • the flow of fluid that exchanges heat can thus be increased and, with it, the performance of the exchanger, without this involving higher energy consumption and costs or resulting in an exchanger or larger volume.
  • the arrangement includes means for controlling the flow of gas that passes through said second conduit and/or means for controlling the flow of fluid that passes through said first conduit.
  • the temperature of the gas or fluid to be cooled or heated can thus be modulated easily.
  • the arrangement includes means for moistening the outer surface of said first conduit while said gas is being drawn in. This promotes an additional fluid-refrigerating effect produced by the evaporation that takes place on the surface of the conduit, so that the performance of the exchanger can be further enhanced.
  • a climatiser that includes the claimed arrangement for exchanging heat when using air as gas exchanger.
  • climatiser is taken to mean an appliance that climatises, that is, an appliance that brings an enclosed space to the temperature, air humidity and sometimes also pressure conditions needed for the health or comfort of those occupying them.
  • the climatiser of the present invention has the advantage over other climatisers of the state of the art that, by using the arrangement for exchanging heat of the invention, it does not as of necessity require conventional refrigeration or heat pumps to cool or heat the air.
  • the climatiser of the present invention can, for example, heat or cool air at a very low energy cost, using only the arrangement for exchanging heat claimed above.
  • the high energy efficiency of the appliance enables channelled air to be obtained at a temperature close to that of the process fluid when it comes into the exchanger.
  • warm air is obtained to climatise a premises at the plant itself.
  • the industry may also have available at one of its plants a low-temperature fluid that may be very useful for cooling the air in some specific working zone in which much heat is generated (a cooking room, for example).
  • the fluid will be used in the exchanger of the present invention to cool the air in that room down to a temperature that will always be a little above that of the aforesaid fluid but that will in any case enable partial refrigeration to be provided.
  • the fluid the climatiser uses is water that can be used both for cooling and heating air. That water can be of industrial origin, as noted above, or it can be household water from a well.
  • the exchanger of the present invention uses well water that is usually at a temperature below ambient temperature, said exchanger will be able to produce refrigerated air for a dwelling, premises or office at a temperature close to that of the well water and, therefore, it can replace the conventional climatiser that uses a refrigeration pump.
  • the climatiser of the present invention may, in addition to the exchanger, have to include means for heating or cooling the water that circulates through said exchanger.
  • This option will be particularly useful where the climatiser is to be used in a dwelling, plant or offices to produce warm air or refrigerated air at a predetermined temperature. In such cases the water that is used will first have to be heated up to a preset value in order to produce the aforesaid warm or cold air.
  • the energy necessary for heating or cooling the water of the exchanger will be from renewable sources, such as solar energy (solar/photovoltaic panels), etc.
  • renewable sources such as solar energy (solar/photovoltaic panels), etc.
  • the climatiser will thus permit climatisation of an enclosed space up to the desired temperature value, in a manner that fully respects the environment and using only water, air and energy from renewable sources.
  • Figures 1a and 1b show two perspective views of a preferred embodiment of the arrangement 1 of the present invention.
  • the gas 2 and fluid 3 conduits have been included inside an enclosed chamber 4 whose outer casing 5 has two inlets 6a, 6b for air 2 and a tubed outlet 7 connected to an aspirator 8 that draws the air 2 from the aforesaid inlets 6 to the aforesaid outlet 7.
  • the casing 5 of the chamber 4 also has an inlet 9 and outlet 10 provided for the fluid 3.
  • Figure 2 shows a view of the interior of the chamber 4 without the outer casing 5, in which it can be observed that the fluid 3 flows through a plurality of vertical finned conduits 11 arranged in two rows, one upper and one lower, interconnected by means of collectors 12, which are also finned.
  • the conduits 11 and collectors 12 of each row are integrated into supports 13 that allow circulation of the aspired gas 2 and, once covered with the outer casing, form the gas conduits 14 of the arrangement 1.
  • FIG. 3 shows, the two rows of conduits 11 and their corresponding supports 13 are interconnected so as to form a circuit 15 of gas 2 and fluid 3 conduits from the inlet 6a to the outlet 7 connected to the aspirator 8.
  • a second gas 3 inlet 6b has been provided that supplies the flow of the pipe 14 as it passes through the second row of fluid conduits 11. That second inlet 6b allows the heat-exchange performance to be optimised still further.
  • Figure 4 shows a schematic plan view of the chamber 4 in which two independent circuits 15a, 15b of conduits 11, 14 for gas 2 and fluid 3 can be observed, arranged in a battery.
  • the two circuits 15 share the same inlets 6a, 6b and outlet 7 for gas and, therefore, also the same aspirator 8.
  • the flow of fluid 3 that exchanges heat can thus be increased and, therewith, the output of the exchanger, without this involving greater equipment energy consumption and cost.
  • a balance pipe 16 is fitted inside the chamber 4.
  • the hot water 3 could be residual water from industrial processes in which heat is generated, while in the case of a household it could be the water from the mains itself, which in the case of hot countries close to deserts habitually ranges between 40°C and 60°C, thereby making the sanitary use of such water 3 difficult and uncomfortable for purposes such as taking a bath, etc.
  • a certain flow of water 3 is made to circulate through the finned pipes 11 of the arrangement 1 while the aspirator 8 draws in the ambient air 2 and takes it through the conduits 14 and to the outlet 7.
  • the exchange of heat takes place inside the aforesaid conduits 14 for forced air 2, in which the aspired air 2 comes into contact under pressure with the outer surface of the finned pipes 11 that contain the hot water 3, absorbing its heat.
  • the efficacy of the arrangement 1 of the present invention is surprisingly high, since it enables a large flow of water 3 cooled to 18°C to be obtained. Furthermore, this is achieved with a very simple design and very low energy consumption that allows savings of nearly 100% of the energy consumption of the conventional equipment that uses water refrigeration pumps.
  • the equipment of the present invention can therefore have an arrangement 1 function and a climatiser 1 function.
  • the hot water 3 generated in industry can be cooled without altering its composition in order to achieve values that allow it to be reused. That same industry could then take advantage of the warm air 2 obtained in order to climatise, for example, the offices zone.
  • the water 3 from the mains can be cooled until it attains values that allow it to be used comfortably and without problems for sanitary purposes, while the warm air 2 that is generated can be put to other uses or expelled to the exterior.
  • the arrangement 1 could be attached to a conventional refrigeration system. The user could thus benefit from the efficiency and energy saving of the equipment of the present invention.
  • the arrangement 1 was used for cooling water 3 and heating air 2; as noted, however, said arrangement 1 could also be used for heating water 3 and cooling air 2.
  • the user should have a supply of air 2, or any other gas, at a high preset temperature to supply the desired heat to said water 3.
  • the energy required to heat said air or gas 2 could come from renewable sources.
