Description
Dual-collector module that integrates an air-to-air heat pump with an air recuperator or heat pumps of a different design equipped with fan coils, in a configuration of distributed and isolated elements of installation design
The subject of the invention is a dual-collector module that integrates an air-to-air heat pump with an air recuperator or heat pumps of a different design equipped with fan coil units, in a configuration of distributed and isolated elements of installation design intended for recuperation, heating and cooling in a single air cycle process, with the possibility of cleaning the air and subjecting it to other processes.
Various types of air recuperation and air purification devices are known.
From the description of the invention no. P 410349, a recuperator is known that has a cylindrical housing, inside of which a recuperated heat space is placed that comprises a heat exchanger with a system of cylindrical pipes.
From the description of the invention no. P 296608, a shell-and-pipe heat exchanger made of aluminium is known. The exchanger consists of four modules connected by collecting pipes of the heating and heated medium. A single heat exchanger module consists of several heating pipes, twisted together in the form of a multiple coil spring, placed in the shell and rolled up in the shape of a flattened coil spring together with the shell. The shell of each module is welded into the collectors, while the heating pipes pass through openings made in these collectors and are welded to their outer walls, connecting through collecting pipes to the collectors.
Heating/cooling devices of two-exchanger or multi-exchanger design using an outdoor exchanger (also referred to as "lower source" in the heating mode) and an indoor exchanger (also referred to as "upper source” in the heating mode), using various cooling mediums (also referred to as "refrigerant", "coolant", "working medium" or "thermodynamic medium") are known. The currently common cooling mediums include air, freons, ammonia, propane, butane, carbon dioxide and glycols. The "lower source" is referred to as the heat exchanger from which heat is supplied, while the "upper source" refers to the exchanger to which heat is supplied. Heating and cooling devices are known in which fan coil units are used, being devices installed inside the facility that are responsible for the transfer of heat from the cooling medium to the air. In their design, fan coil units as devices responsible for the thermal transfer in the room between the cooling medium and the air (by heating or cooling the air) act as indoor heat exchangers. Solutions are known that consist in the installation of air supply and air extractions in the vicinity of room floors; these are based on the assumption that CO2 is heavier than air and, therefore, rests in the lower levels of the room atmosphere. Other systems are also known,
which consist in the installation of the air supply and air extraction in the ceiling or ceiling area; these are based on the assumption that at this level of the room atmosphere, air with a specific dynamic has less adverse effect on thermal comfort due to the so-called "wind cooling" phenomenon. Multi-exchanger units are known to combine individual heat exchangers in assemblies to improve the expected heat recuperation performance. These units are typically used in industrial settings as cascade, series, parallel or combined systems (e.g. with counterflow and parallel recovery).
The disadvantage of counterflow multi-exchanger units in parallel layout results from the phenomenon of "short-circuiting", which involves a short heat circulation (too short a flow path, which limits the efficiency of recuperation by reducing the contact time between the air and the exchangers); this leads to incomplete heat recuperation, possible losses and pressure differences that may require increased electricity consumption by the fans and an uneven operation thereof, the need for regular maintenance of the heat exchangers due to the potential accumulation of pollutants, and the requirement for a suitable location in which multi-exchanger units can be used. This makes these systems unsuitable for use in single and multi-family housing and as in- wall units.
The solution according to the invention overcomes the inconvenience resulting from the state of the art because, as a result of the combination of two air collectors (an inner collector and an outer collector) located on two sides of the exterior wall of the building, the solution according to the invention physically integrates the air-to-air heat pump with the air recuperator by connecting the exhaust pipe of the recuperator to the intake pipe of the bottom source of the heat pump and connects the fresh air supply to intake pipe of the top source of the heat pump. The used air removed by the air recuperator in both summer and winter tends to have temperature parameters that are more favourable for the heat pump as compared to the ambient air temperature. In summer, the air removed from the air recuperator tends to be of a lower temperature than the ambient temperature; in winter, the opposite occurs. In summer in the cooling mode, the heat pump has a higher capacity when the bottom source is supplied with air at a lower temperature; in winter in heating mode, the opposite occurs. Using the air removed by the recuperator to supply the air intake of the bottom source of the heat pump usually exerts an advantageous effect on the performance of the heat pump as compared to using air at ambient temperatures. Furthermore, owing to this hitherto unknown combination, the device according to the invention uses the potential reduced recuperation efficiency for improving the efficiency of heating and cooling of buildings. Losses due to reduced air recuperation efficiency occur as a common phenomenon. The recuperation efficiency parameters quoted on devices and determined by means of specialist tests remain significantly lower under real conditions than the
laboratory-declared ones. Reduced recuperation efficiency is a common phenomenon resulting from the design of recuperators and occurs at increased operating efficiency (increased load), but may also result from contamination of heat exchanger ducts, as a result of mechanical damage, as well as incorrect selection of recuperator to the function of the room/building. Human error or negligence are among the most common causes of reduced efficiency of a recuperation system. Imperfect heat energy recovery in the air recuperation process results in a loss of temperature from the room/facility together with the exhausted air; it is manifested as an increased temperature of the exhausted air in winter relative to the facility (heat loss) or a reduced temperature of the exhaust air in summer relative to the facility (cool loss) . The solution according to the invention uses the potential reduced efficiency of recuperation operation for improving the efficiency of heat pump operation in heating and cooling mode or improving the efficiency of air conditioner operation in cooling mode. The solution according to the invention enables the use of control automatics, known in the state of the art, by adjusting the opening/closure of an air intake grille controlled, for example, by an electric actuator, for the purpose of redirecting the air discharged from the recuperator to the surroundings when this is more favourable, or to supply the air discharged by the recuperator to the air intake pipe of the bottom source of the heat pump. In addition, the solution according to the invention, in contrast to the ones known in the state of the art, enables adapting universal modular facade grilles (acting as an external collector) to individual needs in order to discharge air from the recuperator or to supply it to the heat pump air intake, as well as to connect the ducts of the air intake or air exhaust in order to separate the air intake from the air exhaust.
The device according to the invention uses the existing dependence of the heating capacity and cooling capacity of commercially available air-to-air devices (heat pump, air conditioner, etc.) on the outdoor ambient temperature, by supplying these devices with air discharged by the air recuperator whose temperature is significantly more favourable than that of the outdoor air. The temperature in rooms designed for occupancy oscillates around 20 degrees Celsius, regardless of the season and the outdoor temperature. In summer, the higher the outdoor air temperature, the greater the need for cooling the rooms. However, the higher outdoor temperature contributes to a reduction in the performance of the heat pump in the cooling mode. Conversely, in winter, the lower the outdoor air temperature, the greater the demand for space heating. However, lower outside temperature contributes to a reduction in the performance of the heat pump in the heating mode. The device according to the invention overcomes these disadvantages.
Furthermore, when using the in-wall heat exchangers of the recuperator known in the state of the art, the advantage of the solution according to the invention lies in the fact that it enables
selecting the required recuperation capacity by using the required number of in-wall heat exchangers accordingly.
Furthermore, the device according to the invention overcomes the disadvantages of the state of the art related to the necessity to produce heat exchangers of various sizes and capacities in order to better match the exchanger to the needs of air exchange of individual rooms or facilities. Owing to the use of a dual-collector system, the device according to the invention offers the possibility to produce a single model of heat exchanger, thereby compensating for the dissimilar recuperation capacity requirements posed by various facilities by using several exchangers connected by a dual-collector module into a single recuperation system.
The solution according to the invention advantageously operates with an in-wall (distributed, ductless) recuperation system. In contrast to solutions known in the state of the art, the solution according to the invention, owing to using a dual-collector system, is capable of independent operation, in the case of distributed in-wall recuperation, of each of the three main modules, i.e.: recuperator (with any number of heat exchangers) with an air purifier and a heat pump in the following configurations: recuperator with a purifier and a heat pump; and recuperator with a purifier, recuperator with a heat pump. In addition, in the solution according to the invention, by equipping the inner collecting pipe with complementary negative pressure relief valves, it is possible to simultaneously purify the outdoor air supplied by the recuperators and to purify the indoor air through its secondary circulation.
The solution according to the invention eliminates the inconvenience found in the state of the art, such as the risk of contamination of the recuperation and heating/cooling ducts by eliminating them - the solution can work both in duct and ductless (distributed) systems.
Another advantage of the solution is the use of heat recovery efficiency losses arising on heat exchangers for the improvement in the efficiency of heat pump operation (as the supply of the bottom source), thus significantly increasing the heating efficiency of the heat pump in winter (raising the coefficient of performance - COP) and cooling heat pump in summer (raising the energy efficiency ratio - EER).
The dual-collector module according to the invention is capable of filtering the air and subjecting it to other processes, e.g. ionisation, UV irradiation, humidification, etc.
The solution according to the invention overcomes the inconvenience of the state of the art regardless of the different locations and positioning of fresh air supplies and air extraction in heating-cooling devices that result from the need for separate location of the air conditioner/heat pump/fan coil unit relative the recuperation unit. The solution according to the invention can be effectively applied whenever the heating, cooling or heating/cooling installation comprises a two-exchanger system (consisting of an outdoor and indoor exchanger supplied with air), a
multi-exchanger system, or when the installation consists of an outdoor exchanger supplied with air and fan coil units acting on the temperatures inside the facility thereby serving as an indoor exchanger (heating or cooling the air depending on the operation mode). As a result of using two air collectors (an indoor collector and an outdoor collector) placed on two sides of the outdoor wall of the building (facade), the solution according to the invention enables the integration of the individual sections of the physically dispersed installation by using ventilation duct connections known in the state of the art; this results in the effective integration of the air-to-air heat pump with the air recuperator, regardless of their closer or more distant position relative to each other. The dual-collector module, using ventilation duct connections known in the state of the art, connects the air exhaust of the recuperator to the air intake of the outdoor heat exchanger of the air conditioner or heat pump, and the air supply of the recuperator to the air intake of an indoor heat exchanger of the air conditioner or heat pump, or fan coil (the heat exchangers of these units do not have to operate within the same air conditioner/heat pump).
Air-to-air heat exchange systems with an outdoor and indoor heat exchanger are found in air conditioners, as well as in the most common „split" heat pumps, and in the case of an outdoor monobloc or indoor monobloc system of the heat pump.
The outdoor collector of the dual-collector module can be installed both in the location of the air exhaust of the recuperator and the air intake of the outdoor heat exchanger of the air conditioner or heat pump, as well as in a convenient location between these units. The indoor collector of the dual-collector module can be installed both in the location of the air supply from the recuperator and the air intake of the indoor exchanger of the heat pump/air conditioner/fan coil, as well as at a convenient location between these devices.
The solution according to the invention overcomes the inconvenience resulting from the differences in architectural layouts and construction of facilities, making it possible to design and implement the installation of the dual-collector module both in newly designed installations and by modifying the already existing ones. Regardless of the place of installation of the dual- collector module and the spread of individual devices or their sections (being technologically and structurally distinct devices with specific tasks and processes) within the facility, its operation is based on the mediation of air transfer via collectors and ventilation ducts from the air exhaust of the recuperator to the air intake of the outdoor exchanger and simultaneously from the air supply of the recuperator to the air intake of the indoor exchanger. In the solution according to the invention, the air exhaust and the air supply of the recuperator act as the "supply sources" of the supply ducts, while the air intakes of the outdoor and indoor heat exchangers provide the "supply points" of these ducts.
The dual-collector module according to the invention improves the operation efficiency of ventilation and heating systems that use air conditioners or heat pumps and recuperators, as well as it improves the comfort of using these systems. The redirection of air from the air exhaust of the recuperator to the air intake of the outdoor exchanger of the heating or heating/cooling unit contributes to improving its efficiency in both heating and cooling modes. Redirecting the air from the fresh air intake of the recuperator to the air intake of the indoor exchanger of the heating or heating/cooling unit improves the comfort within the facility in both heating and cooling modes by reducing the locations of fresh air intakes from the recuperation, as well as from heating/cooling systems, thus reducing the locations of uncontrolled "wind cooling" and reducing the locations of possible acoustic emissions.
The dual-collector module according to the invention makes it possible to use ducts known in the state of the art to redirect the exhaust air according to the adopted operating scheme, i.e. from the air exhaust of the recuperator via an outdoor collector by means of a duct (located vertically, horizontally or diagonally) to the air intake of the outdoor exchanger. In the case of adapting the design to spreading the locations of installation of individual (indoor and outdoor) heat exchangers within the facility, it is advantageous to separate the locations of the outdoor and indoor collectors for better performance of the dual-collector module.
The solution according to the invention eliminates the inconvenience in the state of the art resulting from thermal energy losses that occur in air recuperation devices and uses the thermal losses resulting from recuperation for the improvement of the operating efficiency of heating and cooling equipment. The solution according to the invention can be applied to new installations, but also to the existing ones. The dual-collector module with the use of connecting ducts according to the invention enables any connection of further devices for air processing and treatment, for example for air filtration, ionisation, UV irradiation, humidification, etc.
In the solution according to the invention, the connections between the air supply ducts to the supply points (air intakes of heat exchangers) are advantageously of the design known in the state of the art, that is the so-called "unsealed connections". Thanks to such connections, both the outdoor and indoor heat exchanger, by means of the negative pressure generated by the system of forced airflow through the heat exchanger (usually by a fan), automatically compensate for any potential shortage of air supplied through ducts from the air collectors by supplying ambient air. In case excess air is supplied through the ducts from the collectors to the exchangers relative to the demand of the heating and cooling unit, with the use of unsealed connections, this excess air will be discharged into the surroundings.
The essence of the invention lies in the fact that the dual-collector module that integrates an air- to-air heat pump with an air recuperator comprises two collectors - an outdoor collector and an
indoor collector - placed on opposite sides of the exterior wall of the building, as well as at least one heat pump and at least one heat exchanger in the recuperation process, wherein the intake pipe of the bottom source of the heat pump is supplied from the recuperator exhaust, whereas the intake pipe of the upper source of the heat pump is supplied from the recuperator supply, and consists of one or more heat exchanger for air recuperation, an air purifier and a heat pump with an advantageously integrated recuperator exhaust system as heat pump inlet pipe; whereby the outer collecting pipe is advantageously made of fagade modules that form air intake and exhaust chambers and equipped with side sockets of the modules and top and bottom sockets of the modules; whereas the inner collecting pipe is made of separate air intake and exhaust chambers that provide a connection between the recuperator section and the air purifier and/or heat pump; and the air exhaust duct of the recuperator is connected to the intake duct of the heat pump, providing a supply for the bottom source of the heat pump; whereby the recuperator advantageously has more than one heat exchanger; whereby the single-exchanger or multi- exchanger recuperator is arranged in a vertical, in-wall layout. Advantageously the invention consists in that the outdoor and indoor heat exchangers of the heating/cooling device (heat pump/air conditioner), as well as the indoor and outdoor collectors of the dual-collector module and the air recuperator are located in separate locations within the facility, remaining connected to each other by air supply ducts known in the state of the art; whereby the collectors of the dual-collector module are positioned in such a way that the indoor collector is installed on the air supply side (from the point of view of airflow direction) between the air intake of the indoor heat exchanger of the heating-cooling unit and the air supply from the recuperator, and the outdoor collector is installed on the side of air exhaust (from the point of view of airflow direction) between the air intake of the outdoor exchanger of the heating-cooling unit and the air exhaust of the recuperator; whereby the outdoor collector is advantageously connected by supply ducts to at least one outdoor exchanger of the heating-cooling device (heat pump/air conditioner) and at least one air exhaust of the recuperator; whereas the indoor collector is advantageously connected by supply ducts to at least one air supply of the recuperator and at least one indoor exchanger of the heating/cooling device; whereby the dual collector module forms a layout of several intra-wall heat exchangers which are connected to each other by collectors forming a whole, whereby the heat exchangers are advantageously located one above the other, and a fan coil may be used as the indoor exchanger.
A dual-collector module that integrates an air-to-air heat pump with an air-to-air recuperator according to the invention is formed by the reciprocal layout of the individual device blocks combined with one another, i.e. advantageously in a vertical layout of arranged in-wall heat exchangers that constitute the air recuperator and connected on both sides of the outer wall of
the building by collecting pipes, which redirect the air into the interior, i.e. into the block for cleaning and subjecting air to other processes and for subsequent cooling/heating in the process of the upper source of heat pump, whereas from the exterior, they redirect air into the bottom source of the heat pump. The recuperator may comprise one or more in-wall heat exchangers.
A dual-collector module that integrates an air-to-air heat pump with an air-to-air recuperator, according to the invention, comprises two collectors - an outdoor collector and an indoor collector - arranged on opposite sides of the outer wall of a building, as well as at least one heat pump and at least one single-exchanger or multi-exchanger recuperation system. The air intake of the bottom source of the heat pump is supplied from the recuperator exhaust, whereas the air intake of the top source of the heat pump is supplied from the air supply pipe of the recuperator, enabling the use of an in-wall ductless recuperation system and more than one in-wall heat exchanger for air recuperation, an air purifier and a heat pump with advantageously integrated recuperator exhaust system as the heat pump intake.
The in-wall heat exchangers are advantageously arranged in a vertical layout and connected on both sides of the wall by collecting pipes (on the inside by a collecting pipe with fresh air supply and extraction chambers, on the outside by a collecting pipe with air intake and exhaust chambers). Advantageously, the external collector is constructed using universal facade modules with separate air intake and exhaust ducts that function as independent air intake and exhaust chambers, as well as side sockets of the module and top and bottom sockets of the module that enable the removal and installation of pipe caps or air supply/exhaust grids enabling the connection of ducts to ensure the separation of the air intake pipe and the air exhaust pipe. The internal collecting pipe is made up of separate fresh air supply and extract chambers, providing the connection between the recuperation unit and the purifier and/or heat pump. Advantageously, the solution has several in-wall heat exchangers (air-to-air) in ductless/in-wall mode instead of a recuperation unit with duct distribution.
A modular facade grille enables the use of an external collector, enabling the attachment of ducts to provide separation between the air intake and the exhaust, and enabling the use of a single-exchanger or multi-exchanger recuperator in an in-wall, ductless system.
In the solution according to the invention, an air conditioner may be used instead of a heat pump. The method of connecting the external collecting pipe to the air conditioner and to the heat pump is identical.
In the solution according to the invention, ventilation ducts known in the state of the art are used that connect individual units or their separate sections, making it possible, by means of these connections, to integrate the heat exchangers of heating and cooling devices (heat pumps, air conditioners, fan coil units) with air recuperators regardless of the architecture and construction
of the facilities in which they are installed. Regardless of the positioning of the air intake of the outdoor exchanger, the air exhaust of the recuperator and the outdoor collector, the outdoor collector redirects the air discharged from the recuperator and feeds it to the outdoor exchanger of the heating-cooling unit. Regardless of the location of the air intake of the indoor exchanger, the air supply of the recuperator and the indoor collector, the indoor collector redirects the air discharged from the recuperator to the indoor exchanger feeding it to the indoor exchanger of the heating-cooling unit; whereby both the outdoor and indoor exchangers of the heating- cooling units may come in the form of the so-called "split" or indoor or outdoor "monoblock" layout. Both the outdoor collector and the indoor collector may serve the function of only redirecting air to the particular exchanger, as well as the function of collecting and mixing air streams from various supply sources and redirecting them to the supply point, i.e. the particular exchanger of the heating-cooling unit.
In the solution according to the invention, the outdoor collector and the indoor collector of the dual-collector module may be mounted in the location optimal for the arrangement of the installation with account to the architecture and design of the facility between the supply source and the supply point, by means of using ventilation distribution ducts known in the state of the art. The outdoor collector and indoor collector can be installed, for example, at the gravity ventilation chimney both inside and outside (on the roof or chimney) of the building, or on the indoor side of the inlet to the gravity duct or air intake of the indoor exchanger of the heating- cooling unit; depending on where the indoor exchanger is located (inside the facility in the case of "split" or indoor "monoblock" designs, and outside the facility in the case of outdoor monoblock designs).
The connections between the ducts supplying air to the supply points (air intakes of the exchangers of the heating-cooling device) advantageously have the design "unsealed connections" known in the state of the art, owing to which design both the outdoor and indoor heat exchangers of the heating-cooling device, by means of negative pressure generated by the system of forced airflow through the exchanger (usually by a fan), compensate, on their own accord, for any shortage of air supplied through the ducts from the air collectors by supplying ambient air. If excessive air is supplied through the ducts from the collectors to the exchangers, as compared to the demand of the heating-cooling device, the excess will be discharged into the surroundings with the use of unsealed connections.

Fig. 10 presents a diagram of the location of the dual-collector module in a multi-exchanger installation of air conditioners or heat pumps and two independent recuperation units connected to the same dual-collector module.
In a variation of the invention, the recuperator and the heat pump/air conditioner can be placed on different floors of the building, whereby the units are connected to the outdoor collector and the indoor collector by ducts known in the state of the art.
In another variation of the invention, the outdoor collector can be mounted on the roof at the exhaust from the gravity ventilation chimney, whereby the gravity ventilation duct (the so-called
"chimney ventilation duct") acts as air exhaust from the recuperation unit with the air intake duct of the recuperation unit mounted inside; whereas the indoor collector of the dual-collector module is placed on the air supply side of the recuperation unit.
In a variation of the invention, the outdoor "monoblock" heat pump is placed at ground level, advantageously in the vicinity of the outdoor wall of the building, whereas the outdoor collector is mounted on the outdoor facade of the building.
The use of a dual-collector module facilitates arriving at air extraction and air supply locations that are placed advantageously from the point of view of thermal comfort, with the air extraction of air used in the recuperation process being located at floor level, whereas the air supply from the heat pump/air conditioner being located under the ceiling. This solution eliminates the negative feeling of thermal comfort resulting from the so-called "wind cooling" phenomenon, while at the same time effectively extracting the exhaust air from the bottom layer where carbon dioxide content is increased. The use of an outdoor collector in place of an air exhaust allows for supplying air via ventilation ducts known in the state of the art from the outdoor collector to the air intake of the outdoor exchanger, while any potential air supply located at the room floor via the indoor collector is redirected via ducts known in the state of the art from the indoor collector to the air intake of the upper source of the heat pump (indoor heat exchanger).
If the airflow is to be provided between rooms located in different locations in the building, when the air conditioner/heat pump and the air supply from the recuperator or fan coil units are located on different floors, the use of a dual-collector module will enable the desired airflow in this way, that the air discharged from the recuperator to the outdoor collector and further via the ventilation duct known in the state of the art will be redirected to the air intake of the lower source (outdoor exchanger) of the heat pump, while the air supply from the recuperator via the indoor collector and further via the ventilation duct known in the state of the art will be redirected to the air intake of the upper source of a heat pump (indoor exchanger) or fan coil unit.
The air discharged by the recuperator, having passed through the outdoor collector on the outer side of the facade, is supplied through a ventilation duct to the air intake of the lower source of the heat pump/air conditioner, whereas fresh air supplied by the recuperator is supplied through the indoor collector to the indoor exchanger of the heat pump/air conditioner or to the fan coil.
In a variation of the solution, the outdoor collector is installed at the gravity ventilation chimney, and the gravity ventilation duct also serves as an air exhaust from the recuperation unit. Having passed through the gravity ventilation duct, the air is supplied to the outdoor collector, from where it flows through the duct to the roof-mounted lower source of the heat pump. At the same time, the indoor collector of the dual-collector module is placed on the air supply side from the
recuperation unit and the air supplied through the collector is fed from the upper source of the heat pump (indoor exchanger) located inside the facility.
In another variation of the invention, the outdoor "monoblock" heat pump is placed at ground level in the vicinity of the exterior wall of the building. An outdoor collector mounted on the outer facade redirects the air discharged by the recuperator to the air intake of the lower source (outdoor exchanger) of the outdoor "monoblock" heat pump.
The dual-collector module according to the invention can be combined with a recuperation unit, whereby the outdoor collector is connected to an exhaust of the central recuperation system, through which the air flows to the outdoor heat exchanger of the heat pump/air conditioner, whereas the air supply from the recuperation unit is supplied to the indoor collector; the recuperation unit redirects the air to the indoor heat exchanger of the heat pump/air conditioner or to the convector.
In a variation of the invention involving the use of a double-collector module enclosing a multi- exchanger in-wall vertical layout of parallelly connected heat exchangers, several state-of-the- art disadvantages are eliminated. The vertical layout of the heat exchangers of the recuperator through the wall (exchangers in a horizontal position, connected parallelly and arranged vertically one above the other) saves space. This layout minimises negative interference with the load-bearing structure and the effects of weakening the wall structure (it provides relatively the best distribution of vertical loads, which contributes to structural stability). In addition, it is the most flexible layout in terms of adapting to the needs and capabilities of the facility, allowing the required number of exchangers to be used. It also minimises heat loss, as thermal energy is mainly dispersed vertically, thereby limiting energy dissipation and loss. According to Pascal's law, a change in pressure exerted on a liquid or gas in a closed vessel is transferred unchanged to the entire volume of the fluid.
In this system, changes in one of the exchangers (for example, an increase in pressure) are transferred to the entire system of interconnected exchangers (vessels) thereby equalizing the pressure throughout the system, which contributes to an even pressure distribution and ensures more stable operating conditions. This system, thus, ensures uniform pressure, stable flows, minimised pressure losses and even operating conditions for the heat exchangers. This improves operating efficiency and reduces electricity consumption (fan operation). Additionally, this layout facilitates an aesthetically pleasing closure (through the vertical shape of the dual- collector module similar to pilasters).
In the variation of the dual-collector module that allows easy assembly and disassembly of the indoor collector structurally connected to the in-wall exchangers through the use of easily demountable mechanical or magnetic connections known in the state of the art, this design
allows access to and removal of the in-wall exchangers, which solves the problem of their maintenance or possible replacement.
The in-wall collector is easily demountable, which facilitates maintenance or replacement of the heat exchangers.
The solution according to the invention is shown in an example non-limiting to the invention. E x a m p l e 1:
The recuperator may come with more than one heat exchanger. The accompanying drawings indicate a triple-exchanger recuperator in a ductless, in-wall system.
The dual-collector module that integrates the air-to-air heat pump with the air-to-air recuperator consists of two collectors - an outdoor collector (2,3) and an indoor collector (21,22) - placed on opposite sides of the exterior wall of the building. The outer collector (2,3) is advantageously constructed with facade grille modules that form the air intake (3) and exhaust (2) chambers. The internal collector (21, 22) is constructed with separate fresh air supply (22) and exhaust (21) chambers, forming a connection between the recuperator section and the purifier (19, 20) and/or heat pump (11, 15).
In a dual-collector module that integrates an air-to-air heat pump with an air recuperator according to the invention, the in-wall (air-to-air) heat exchangers (1) are advantageously placed one above the other and connected to the collectors: the inner collector - fresh air supply chamber (22), the exhaust chamber (21) and the outer collector - exhaust chamber (2) and the intake chamber (3). The exhaust chamber (2) is equipped with check valves (5) and exhaust grilles with a stream redirect apparatus and the possibility for opening/closure by means of an electric actuator (4). Closing the exhaust grille (4) redirects the air from the exhaust of the in- wall heat exchangers (1) via the check valves (5) towards the air intake of the heat pump (9). The closing or opening of the exhaust grille (4) is decided by the automation, known in the state of the art, based on information obtained from the exhaust air temperature sensors with which the inside-wall heat exchangers (1) are equipped and based on information obtained from the outside temperature sensor (6). Any potential shortage with regards to the demand for airflow in the air intake pipe of the bottom source of the heat pump relative to the amount of air fed through the recuperator exchangers will be automatically supplemented by a negative pressure relief valve (7). The heat energy generated by the heat pump through the external heat pump exchanger (12) will be transferred, in a system known in the state of the art, to the heat pump exchanger of the internal chamber (17), depending on the mode of operation of the heat pump either cooling or heating the air supplied to the heat pump through the fresh air supply duct of the recuperator via the purifier (17). A drip tray (14) gravitationally drains the condensate generated in the heat pump chamber to the pump exhaust (8) in the heat pump in-wall duct (10).
Between the indoor collecting pipe (21, 22) and the heat pump, an air purifier with purification filters (19), with a fan enabling the expected compression (20) and possible other air preparation processes, e.g. air humidification using a condensate container/air humidification (23) are placed. Possible excess condensate supplied from the upper and middle exchangers to the recuperator container is gravitationally drained by overflow to the external collecting pipe module of the air intake chamber (3) by means of the bottom exchanger and drained outside via the eaves (via a drip).
The pressure difference generated by the automation (control), resulting from the higher flow intensity of the air purifier fan (20) relative to the air supply through the recuperator heat exchangers (1) to the inner collecting pipe of the supply chamber (22) will result in negative pressure occurring in the supply chamber (22) and the compensation by a complementary negative pressure relief valve (7) located therein and in further purification of the inner air through its secondary circuit.
At the bottom of the inner collecting pipe, an exhaust chamber (21) of the inner collector, a condensate container (23) and the negative pressure relief valve (7) are placed. At the outer end of the duct (18) supplying air from the purifier to the heat pump, an internal heat pump exchanger (17) and a fresh air supply opening (16) are placed. The internal heat pump exchanger (17) and the fresh air supply opening (16) are located in the internal chamber (15) of the heat pump. Behind the internal heat pump exchanger (17) a drip tray (14) is placed, whereas above the heat pump fan (13), the external heat pump exchanger (12) and the external chamber (11) of the heat pump are placed. These elements are placed above the shared in-wall duct (10) of the heat pump (air intake - exhaust). Alternatively to the combination with a heat pump of the mono-block type, the device according to the invention can be combined with a heat pump of a "split" type. At the end of the shared in-wall duct (10), the air intake (9) of the heat pump and the exhaust (8) of the heat pump are placed. In the in-wall module, i.e., ductless module, the air intake with exhaust and fresh air supply are integrated.
On the chambers of the exhaust (2), grilles with a guide apparatus (4) are placed, enabling opening/closure with an electric actuator known in the state of the art or offering the ability to manually fix the position in a manner known in the state of the art.
At the complementary negative pressure relief valve (7), an external temperature sensor is placed (6).
Facade grilles (24) are mounted on the heat exchangers (1). Facade grilles (24) and side grilles (27) have side pipe caps (26). All grilles are removable. In the places of these pipe caps (26), when removed, air intake duct connections are placed. The grille (24) placed on top has a top cover (25), in the shape of a canopy for draining precipitation. The grilles also function as an
aesthetically pleasing enclosure for the in-wall recuperator and the collecting pipes of the air intake and exhaust (from outside the wall), which redirect the air discharged from the recuperator to supply the heat pump. Grilles separate the air intake and exhaust ducts by means of a system of side pipe caps (26), where flat ducts can be connected on the facade.

A dual-collector module that integrates an air-to-air heat pump with an air-to-air recuperator consisting of two collecting pipes: an outdoor collecting pipe (2, 3) and an indoor collecting pipe (21, 22) located on opposite sides of the outside wall of the building, as well as one air conditioner and one in-wall recuperator in a multi-channel ductless recuperation system. The air intake of the bottom source of the air conditioner is supplied from the exhaust chamber of the recuperator (2) and the fresh air intake of the upper source of the air conditioner is supplied from the fresh air supply chamber of the indoor collecting pipe (22). It is advantageous when the dual-collector module cooperates with a ductless in-wall recuperator.
In the dual-collector module according to the invention, the in-wall heat exchangers (air-to-air) (1) are placed one above the other and are located in the inner collecting pipe (fresh air supply chamber) (22) and have, on one side, an opening that constitutes the exhaust of the recuperated air - the exhaust chamber (2) and a check valve (5); on the other side, they have an exhaust (21), a purifier fan (20), an air filter (19) and a duct (18) that supplies air from the purifier to the air conditioner. At the lower end of the inner collecting pipe, an exhaust chamber (21) of the inner collecting pipe, a condensate tank (23) and a negative pressure relief valve (7) are placed. At the outer end of the duct (18) supplying air from the purifier to the air conditioner, an internal heat exchanger (17) and fresh air supply opening (16) are placed. The internal heat exchanger and fresh air supply opening (16) are located in the inner chamber (15). Behind the internal heat exchanger (17), a drip tray (14) is placed, and above the fan, the external heat exchanger (12) and the external chamber (11) are placed. These components are placed above the shared in-wall duct (10) of the air conditioner. As an alternative to the combination with an air conditioner of a mono-block type, the device according to the invention can be combined with an air conditioner of a "split" type. At the end of the shared in-wall duct (10), an air intake exhaust is placed. The method of connecting an outdoor collecting pipe to a monoblock-type air conditioner is identical to that of connecting an outdoor collecting pipe in a monoblock-type system to a heat pump.
On the exhaust chambers (2), exhaust grilles are installed with stream redirect apparatus (4) with the possibility for opening/closure with an electric actuator known in the state of the art or with the possibility to manually fix the position in a way known in the state of the art.
An outdoor temperature sensor (6) is placed at the negative pressure relief valve (7).
Facade grilles (24) are installed on the heat exchangers (1). The facade grilles (24) and side grilles (27) are equipped with side pipe caps (26). All grilles are removable. In the place of side pipe caps (26), when removed, the air intake duct connections are located. The grille (24) located at the top of the grille system has a top cover (25), in the shape of a canopy for draining precipitation. The grilles also function as an aesthetically pleasing enclosure for the in-wall recuperator and the collecting pipes of the air intakes and exhausts (from outside the wall), which redirect the air removed from the recuperator to supply the air conditioner. The grilles separate the air intake and exhaust ducts by means of a system of side pipe caps (26), at which places flat ducts on the facade can be connected.

At this point, an outdoor collector (2, 3) of the dual-collector module is mounted on the fatjade, from which the air is redirected upwards via a vertical ventilation duct (18) and is connected to the air intake of the outdoor exchanger (12) of a "split" air conditioner known in the state of the art. Owing to this, the exhaust air after recuperation, having more favourable temperature parameters than the ambient air, constitutes a more favourable source for the outdoor exchanger of the air conditioner (12).

In this way, the fresh air supplied by the recuperation unit with duct distribution (29) and fed to the air conditioner (17) inside the building is cooled or heated to the expected parameters, ensuring user comfort.
The air purifier section (28) comprises filters, known in the state of the art, and is connected by an indoor collector (21, 22) to the indoor exchanger of the air conditioner (17); mediating in the air supply and purifying it.

This module has an outdoor collector (2, 3), and an indoor collector (21, 22) connected to the in-wall heat exchangers of the recuperator (1) and the air purifier section (28); these devices are remote from the air intake of the outdoor heat exchanger (12) of the heat pump/air conditioner and

From the air supply chamber of the indoor collector (22), via the ventilation duct (18) known in the state of the art, the air supply is fed to the air intake of the indoor exchanger (17) of the heat pump/air conditioner; as a result, the fresh air supplied to the room via the in-wall recuperation unit will be heated or cooled as required. At the same time, the exhaust air discharged by the in-wall recuperation unit via the exhaust module of the outdoor collector (2) is fed via the ventilation duct (18) known in the state of the art to the air intake of the outdoor heat exchanger (12) of the heat pump, improving its performance in both heating and cooling modes.
E x a m p l e 5:
A dual-collector module that integrates an air-to-air heat pump with an air-to-air recuperator or heat pumps of a different design equipped with fan coil units, in a configuration of distributed and separated elements of the system design, in which the air-to-water heat pump installed on the roof of the building supplies the cooling medium to the wall-mounted fan coil units that act as indoor exchangers/wall-mounted radiators in this system, to which the air is supplied from the air supply chamber of the indoor collector. The dual-collector module consists of an outdoor collector (2, 3) placed on the roof of the building, directly at the outlet of the gravity ventilation duct (30) that is used as the exhaust duct of the recuperator. The used air having advantageous temperature parameters, is discharged by the recuperation unit through the gravity ventilation duct to the outdoor collector (2, 3) from where, through the ventilation duct (18) known in the state of the art and adjusted in terms of cross-section to the assumed operation parameters, it is supplied to the air intake of the outdoor exchanger (12) of the heat pump, thus improving its operation parameters. At the same time, the indoor collector (21, 22) of the dual-collector module placed inside the building on the side of air supply from the recuperation unit receives the fresh air following its recuperation and transmits it via the ventilation duct (18) known in the state of the art and adjusted in terms of cross-section to the assumed operating parameters to the air intake of the fan coil unit (31) supplied with water from the heat pump. In this way, the thermal energy transferred by the cooling medium (water) is supplied to the fan coil unit (31), which transfers this energy in the room to the air supplied from the air supply of the recuperator via the fresh supply air chamber (22) of the indoor collector module. The fan coil units (31) with a forced airflow layout similar to heat exchangers, are mounted in a manner similar to that of wall-mounted radiators, thereby heating or cooling the room air. The supply air from the recuperation unit with duct distribution (29), rather than being directed to the indoor exchanger, is supplied to the fan coil unit (31) where it obtains the expected thermal parameters.
