    [0004] The present invention refers to air heating equipment, one of those used in enclosures normally intended for the rearing and fattening of animals, which through the heat generated manages to introduce hot air into the enclosure, expelling the gases resulting from combustion to the outside .
    [0006] The present invention also relates to a modified hot air generator for use in such a heating system.
    [0008] Background of the invention
    [0010] In the air conditioning of animal husbandry facilities, heating equipment based on a sealed combustion hot air generator is known. These generators release the combustion exhaust gases, mainly carbon dioxide, outside the installation. In these facilities designed to house animals and keep them at a comfortable temperature for their correct growth and fattening, the exhaust gases from the combustion of a heat generator must necessarily be expelled outside the enclosure to avoid the death of the animals by poisoning of carbon dioxide.
    [0012] In facilities with animals, the temperature and air quality inside the facility are key to avoid the mortality of these animals, which, due to their characteristics, are very sensitive to changes in temperature and air quality. such as, for example, poultry farms.
    [0014] To date, many efforts have been devoted to designing heating systems based on controlling the temperature inside the enclosure so that said temperature is within a range of comfort for the animals and based on the quality of the air inside the enclosure. installation, so the combustion exhaust gases have been considered more of a drawback than a source of usable heat.
    [0016] Thus, heating equipment used in animal facilities has been based mainly on hot air generators with tight combustion that do not release exhaust gases containing carbon dioxide into the facility enclosure in order to avoid contamination of the air inside the enclosure. Therefore, to date, the heat resulting from combustion in the generator is wasted, losing thermal energy that is released outside the poultry facility, together with the combustion exhaust gases from the generator.
    [0018] Although improved heating systems have been described, these are heating systems for drying materials where the air quality is independent of the target temperature inside the facility enclosure. Thus, for example, the international patent application WO201053278 describes the use of the heat generated in the gases produced by combustion in a generator by introducing them inside an enclosure for an installation destined to the drying of products that once dried the air is renewed of the installation with fresh air in order to be suitable for the access of an operator. In this type of facility, not intended for the rearing and fattening of poultry, the combustion exhaust gases are released into the enclosure since exceeding the permitted limits of carbon dioxide concentration for human or animal use is not an inconvenience. for the purpose of drying, although the air must be renewed in a final stage to give access to the operator.
    [0020] Therefore, there is not yet a solution for the particular problem of heating in poultry farms, nor in general in animal husbandry and fattening facilities, so it is still desirable to provide a heating system for an enclosure of a facility. that allows a control of the temperature and the quality of the air inside the enclosure, with improved energy efficiency.
    [0022] Description of the invention
    [0024] With the air heating equipment of the invention and the hot air generator that it includes, the aforementioned drawbacks are resolved, also presenting other advantages that will be described below.
    [0026] As a first aspect of the present invention, it proposes an air heating equipment for an enclosure, preferably for an animal husbandry facility with improved energy efficiency.
    [0027] The present invention is based on air heating equipment, one of which conditions the interior environment of enclosures by heating the air from outside the enclosure and leading it to the interior of said enclosure and / or heating the air from inside the enclosure and redirecting it back inside said enclosure. This equipment comprises at least one generator of hot combustion air provided with an exchanger to heat said air flow.
    [0029] The invention is characterized by the fact that the heating equipment, in addition to the hot air generator, has at least one heat recovery device, wherein said recovery device has at least:
    [0030] - an air inlet system to the heat recovery device from inside the enclosure;
    [0031] - an air inlet duct or chamber from inside the enclosure (i) that starts from the air inlet system and communicates with a preheating exchanger.
    [0032] - a preheating exchanger with an air circuit coming from the air inlet duct or chamber from inside the enclosure and leading to the outside, which exchanges its heat energy with an air circuit coming from outside to the preheating exchanger and, where the air circuit coming from the outside ends in an air inlet system to the hot air generator for its subsequent entry into the enclosure, where the entrance to the preheating exchanger, at least from the air inlet duct or chamber , from inside the enclosure it can be selectively opened or closed;
    [0033] This configuration is also characterized by the fact that, between the heat recovery device and the hot air generator, there is at least:
    [0034] - a system for connecting the inlet gases produced by combustion from the hot air generator, to the air inlet duct or chamber from inside the enclosure, with selective opening or closing allowing the passage or not of the gases produced by the combustion to the duct or chamber;
    [0035] - a connection system for recirculation of the interior air of the enclosure that passes from the air inlet duct or chamber from inside the enclosure, towards the hot air generator, with selective opening or closing, for recirculation inside the enclosure; Finally, the invention is also characterized by the fact that the heating equipment has control means that act, at least, on the hot air generator, on the air inlet systems and on the connection systems, allowing and / or regulating the flow of air through them automatically and / or manually.
    [0036] These characteristics make it possible to include in a unit a generation of hot air for the air conditioning of an enclosure, together with the recovery of heat provided by the interior air of the enclosure that is extracted for its renewal, as well as by the recovery of heat from the product gases of combustion, all in the same equipment, under the same control system. This equipment achieves a better use of the heat energy of the fluids existing both in the enclosure, as well as in the generation of heat itself, in an efficient way and without adding combustion product gases to the environment of the enclosure.
    [0038] Preferably, in the present invention, the passage of the gases produced by combustion through the air inlet duct or chamber from inside the enclosure is done by mixing with the air that enters the recovery device from inside the enclosure to both mixed, after passing through the exchanger of the recovery device, be expelled to the outside.
    [0040] This configuration makes it possible to make a greater contribution of heat energy to the air flow destined to preheat the air flow that enters the recuperator from the outside, prior to generating hot air.
    [0042] For this advantageous configuration with a greater contribution of heat energy, optionally but preferably, the heat recovery device has, in the air inlet duct or chamber from inside the enclosure, internal baffles for homogenizing the mixture of gases prior to entering the exchanger of the heat recovery device and their subsequent exit to the outside.
    [0044] With the installation of these deflectors we are able to carry out an effective and homogeneous mixture of the gases produced by combustion with the air extracted from the interior of the enclosure, to preheat, also in a homogeneous way, the air from the outside that passes through the recuperator.
    [0046] Alternatively, a recovery device can be provided where the passage of the gases produced by combustion through the air inlet duct or chamber from inside the enclosure is done in a closed circuit without mixing with the air from inside of the enclosure, as a previous exchanger.
    [0048] This configuration option performs a heating of the air coming from inside the enclosure prior to the entrance of the recuperator exchanger, without mixing with the gases product of combustion, leaving these gases product of combustion in a watertight circuit, without risk of mixing or entering the enclosure, but losing a part of the heat energy of the gases product of combustion in the exchange through of said previous exchanger.
    [0050] Preferably, the air inlet systems have extraction / impulsion fans to provide the corresponding air flow to the heating equipment. Accordingly, in a preferred configuration of the invention, the heating equipment only has two fans, a single one to drive air from outside to enter the hot air generator through the heat exchanger of the recovery device, and a Unique fan for the extraction of air from inside the enclosure for its entry to the recovery device.
    [0052] This configuration makes it possible to save a fan with respect to the conventional configuration of using recuperators and hot air generators separately, with the consequent savings in material and electrical consumption associated with the present advantageous configuration.
    [0054] As a preferred configuration option of the present invention, the heating equipment control means comprise a processing and control unit that receives information from environmental sensors inside and outside the enclosure to which it is connected, as well as from the operating parameters programmed in said unit and / or remote external devices, acting automatically on the operation:
    [0055] - from the air inlet system to the heat recovery device from inside the enclosure;
    [0056] - from the air inlet system to the hot air generator, through the heat exchanger of the recovery device, for its subsequent entry into the enclosure (i);
    [0057] - from the hot air generator;
    [0058] - from the selective opening or closing position of the combustion product gas inlet connection system from the hot air generator to the air inlet duct or chamber from inside the enclosure; and
    [0059] - the selective opening or closing position of the connection system for recirculation of the interior air of the enclosure, from the air inlet duct or chamber, towards the hot air generator.
    [0061] This allows you to automate the operating modes, such as the renewal with preheating of the outside air in the recovery device and subsequent heating in the generator; or the heating in the generator of the air inside the enclosure in recirculation; or the renewal mode with only preheating of the outside air in the recuperator. Each of these modes requires the activation, closing or opening of the different indicated devices / systems.
    [0063] Preferably, these control means act on the selective opening or closing position of the combustion gas inlet connection system from the hot air generator, to the air inlet duct or chamber from inside the enclosure, enabling the passage of combustion product gases to the duct or chamber, only when the air inlet system to the heat recovery device is activated from inside the enclosure and the selective position of the internal air recirculation connection system of the enclosure, from the air inlet duct or chamber, is closed towards the hot air generator.
    [0065] This configuration makes it possible to ensure correct operation from the point of view of the need to avoid the entry of combustion gases into the enclosure, in the modes of use where the entry of combustion gases into the duct or chamber of the recovery device is performed. .
    [0067] Optionally, the hot air generator is connected to more than one heat recovery device and / or more than one room to be conditioned. In this way, it is possible to provide service with a single hot air generator element, more than one recuperator or enclosure and thus be able to adapt to the different configurations of the facilities where it is located, deriving the connections between generator and recuperator / s, as well as the outside air inlets and / or the air inlets to the rooms, depending on the number of them that exist.
    [0069] In a preferred manner in the present invention, the heat recovery device has to comprise a cross-flow type exchanger.
    [0071] In a preferred embodiment of the invention, the heating equipment consists of a compact equipment that incorporates under the same casing, at least one hot air generator and a recovery device.
    [0073] The creation of a compact equipment, which under the same casing / body allows the location and coupling of the generator and recovery device with the above characteristics.
    [0074] According to a second aspect of the invention, there is a hot air generator, one of which is used in heating equipment such as that described above, provided with an exchanger for heating by means of the gases produced by combustion and / or by flame heating, the air from outside the enclosure, to be introduced inside the enclosure, and / or to heat the air from inside the enclosure to be recirculated back into the enclosure.
    [0076] This hot air generator is characterized by the fact that it comprises, at least:
    [0077] - an air inlet system, coming from outside, to the hot air generator for its subsequent entry into the enclosure, coupled to the air circuit of the exchanger of the heat recovery device from outside;
    [0078] - an air outlet from the hot air generator into the enclosure;
    [0079] - means for the recirculation connection of the interior air of the enclosure that passes through the air inlet duct or chamber from the interior of the enclosure, towards the hot air generator, with selective opening or closing, for its recirculation inside the enclosure; - Means for conducting and directing the combustion exhaust gases to the heat recovery device, in its system for connecting the gases product of combustion to the air inlet duct or chamber from inside the enclosure, with opening or selective closure allowing the passage or not of the gases produced by combustion to the duct or chamber.
    [0081] Said hot air generator, with this configuration, makes it possible to have advantageous operating modes, as seen above, in the operation coupled to a heat recovery unit.
    [0083] Optionally, the hot air generator has means of connection to two or more heat recovery devices and / or to two or more rooms.

    [0096] Description of a preferred embodiment
    [0098] As can be seen in Figure 1, the invention refers to air heating equipment (10), which is installed in an animal husbandry facility outside (e) of an enclosure, having connection with the interior (i) of said enclosure, both for the extraction of ambient air, and for the supply of heated air.
    [0100] The air heating equipment (10) is formed, in the present embodiment, by a hot air generator (12) and by a recovery device (11), both under the same outer body or casing forming a compact set.
    [0102] The heating equipment (10) is connected to the interior of the enclosure (i) by means of an air inlet system (111) to the heat recovery device (11) from said interior of the enclosure (i). In this embodiment, this air inlet (111) is made through a duct with an extraction fan, which draws stale air from inside the enclosure (i) to introduce it into the duct or chamber (112) of the recuperator (11) that It can be led to the outside (e) through an exchanger (13), of the cross flow type, for preheating the incoming outside air, as happens in the operating modes represented in Figures 2 and 4, or it can be recirculated at through the hot air generator (12), where it is heated to be reintroduced into the enclosure (i), as happens in the operating mode represented in figure 3.
    [0103] The choice of the path to be followed by the air extracted from the interior of the enclosure (i), can be selected from a recirculation connection system (114), formed by a hatch-like selector that alternately allows the conduction of the interior air of the enclosure that passes from the duct or chamber (112) its passage towards the preheating exchanger (13) and its subsequent expulsion to the outside (e), or towards the hot air generator (12) for its recirculation inside the enclosure ( i).
    [0105] In the duct or chamber (112) of the recuperator (11) there is an inlet connection system for gases produced by combustion (113) from the hot air generator (12), with a selective opening or closing of the hatch , which creates said connection system in the present embodiment, allowing the passage or not of the gases product of the combustion to the duct or chamber (112), for their mixture with the air extracted from the interior of the enclosure (i), and thus increase the temperature of the gas mixture, formed by said stale air and said gases product of combustion. To carry out this mixture between the stale air from inside the enclosure (i) and the gases produced by combustion, alternatively there are baffles in the duct or chamber (112) of the recuperator (11) to create the necessary turbulence for said gas mixture.
    [0107] In this way, in the case of making said gas mixture, and as can be seen in figure 2, it is directed to the preheating exchanger (13) of the recovery device (11), providing a greater heat energy. In this operating mode, the control system that automatically governs the operation of the fans, the hot air generator (12) and the position of the different flaps (113, 114), prevents any possible passage of gases into the interior of the enclosure (i), so that the air inlet extraction fan (111) must be in operation, preventing possible gases from combustion from being directed into the enclosure (i), and the hatch of the ventilation system recirculation connection (114) must be closed, preventing the passage of recirculation with gases product of the combustion and forcing its passage to the circuit (115) of the exchanger (13) that carries out its subsequent expulsion to the outside (e) of said mixture of gases including gases product of combustion.
    [0109] In an alternative and / or complementary way, there is an outlet for gases produced by combustion to the area of the duct or chamber (112) of the recovery device (11), but in a closed circuit, as an exchanger that does not allow contact direct and the gas mixture, if not it simply performs a first heating of the air that is extracted from the interior of the enclosure (i). This, although it is not as efficient with respect to the possibility of increasing the temperature of the gases that are passed through the exchanger (13) of the recuperator that preheats the outside air that enters the hot air generator (12), would allow to carry out a preheat in recirculation mode.
    [0111] In the operating modes in which an air renewal is carried out, such as those shown in Figures 2 and 4, the air extracted from the interior of the enclosure (i) through the stale air inlet to the recuperator (11) is conducted to the preheating exchanger (13), in which, in a sealed manner, it exchanges heat with the outside air (e) that is introduced through said exchanger (13) towards the hot air generator (12), arriving preheated by the heat exchange carried out with the stale air, which may or may not contain the gases produced by the combustion of the generator (12), depending on whether the hatch corresponding to the connection (113) from the generator (12) to the duct has been opened or pipeline (112) of the recovery device (11).
    [0113] As indicated, the preheating exchanger (13) has the circuit (115) coming from the duct or chamber (112) of the recovery device (11) and the circuit (116) for the inlet of air from outside (e), sucked by the fan corresponding to the air inlet system (121) to the hot air generator (12).
    [0115] Once this passage has been made through the exchanger (13), the outside air passes through the hot air generator (12), where, if it is in operation, it is heated prior to entering the interior of the enclosure (i), thanks to the heat exchange with the heating chamber or exchanger (122) of the generator (12).
    [0117] In the present embodiment, the control means of the heating equipment (10) are automated and comprise a processing and control unit that receives information from environmental sensors inside (i) and outside (e) of the enclosure to which it is connected. , as well as the operating parameters programmed in said unit and / or remote external devices, acting automatically on the operation of the air inlet system (111) to the heat recovery device (11) from inside the enclosure (i) ; from the air inlet system (121) to the hot air generator (12), through the heat exchanger of the recovery device, for its subsequent entry into the enclosure (i); of the hot air generator (12); of the selective opening or closing position of the combustion product gas inlet connection system (113) from the hot air generator (12), to the air inlet duct or chamber (112) from inside the enclosure ( i); and the position selective opening or closing of the recirculation connection system (114) of the interior air of the enclosure (i), from the air inlet duct or chamber (112), towards the hot air generator (12).
    [0119] The control means preferably make it possible to control the speed of the two fans associated with the air inlets (111, 121) to the equipment (10) to optimize the flow of fluids and their heat exchange.
    [0121] These control means govern in an automated way said elements and devices to make a supply of heated air to the interior of the enclosure (i) which can be.
    [0122] - A heated air recirculation of the interior enclosure (i), by means of:
    [0123] or passing through the exchanger (122) of the hot air generator (12); and / or or passage through the conduit or chamber (112) of the recovery device (11) via an exchanger with combustion gases from the closed circuit. - A supply of outside air (e) heated by:
    [0124] or a preheating by passing through the exchanger (13) of the recovery device (11) with heat exchange with the stale air, either with this stale air simply or mixed with the gases produced by combustion; me
    [0125] or passing through the exchanger (122) of the hot air generator (12).
    [0127] In the preferred embodiment, configured with having a combustion product gas inlet connection system (113), from the hot air generator (12) to the duct or chamber (112), for mixing with the air extracted from the Inside the enclosure (i), the control means act on the selective opening or closing position of said combustion product gas inlet connection system (113) from the hot air generator (12), to the duct or chamber air inlet (112) from inside the enclosure (i), enabling the passage of the gases produced by combustion to the duct or chamber (112), only when the air inlet system (111) to the device is activated heat recovery unit (11) from inside the enclosure (i) and the selective position of the recirculation connection system (114) of the air inside the enclosure (i), from the air inlet duct or chamber (112), is closed to the hot air generator te (12).
    [0129] In alternative embodiments, it is possible to have two or more recuperator devices (11) associated with a single generator, having the same connections between generator (12) and recuperator (11) between each of them, in order to have the same particularities of functioning.
    [0131] In the same way, also alternatively, the generator (12) can introduce heated air into two or more rooms from the same generator (12).
    [0133] The constructive parts of a combustion generator, such as a burner, turbine, exchanger chamber, combustion chamber, burner injectors, etc. are part of the general knowledge of an expert in the field.
    [0135] Although reference has been made to a specific embodiment of the invention, it is clear to a person skilled in the art that the described heating and generator equipment are susceptible to numerous variations and modifications, such as, for example, the type of exchanger or materials in which said exchangers are manufactured, and that all the aforementioned details can be substituted by other technically equivalent ones, without departing from the scope of protection defined by the attached claims.
