PREFERRED EMBODIMENT OF THE INVENTION

The ventilation and air conditioning system of a dwelling object of the invention comprises: an aerator device (1), a vacuum device (2) and a wireless control module (3). The aerator device (1) and the aspirator device (2) are connected by two pipes through which a cooling fluid circulates, a pipe for the fluid in the gaseous state (4) and another pipe for the fluid in the liquid state (5).

When defining the invention, it is necessary to differentiate the different rooms that make up a home, since depending on the room, a kitchen, a bathroom or toilet, a living area, a passageway or a bedroom, the device that It is different because the needs of these rooms are different. Therefore, throughout this report, wet rooms (6) will be referred to as kitchens and bathrooms or toilets, and dry rooms (7) to living rooms, dining rooms or bedrooms.

The aerator device (1) is the device in charge of introducing the outside air into the house and is located in the wall or carpentry of the facade. The aerator device (1) controls the flow of air that lets in the interior of the house, filters it from particles and thermally conditions it if necessary.

The vacuum device (2) is responsible for extracting stale air from the wet rooms (6), which in turn come from the dry rooms (7) through passageways. That stale air expels it to the outside, either directly on the facade or through collective conduit if

there would be. The vacuum device (2) manages to put the damp rooms (6) into depression, preventing the transmission of its stale air to the dry rooms (7).

Under certain conditions, in which the outdoor temperature coincides with the indoor comfort temperature, the vacuum device (2) can cause a greater flow of outside air intake than is strictly necessary to perform a ventilation of the wet rooms (6). The vacuum device (2) controls the air that is extracted from each humid room (6), filtering the one coming from the fume hood of the kitchen and recovering the energy of all the air that is expelled. Part of the energy of the air that is expelled, is heat that recovered would be able to be used for a domestic hot water tank (31).

The wireless control modules (3) are remote controls that are located in all dry rooms (7) with a multiple purpose: record the real comfort conditions of the room to transmit them to the aerator device (1) and through it to the vacuum device (2) to adapt to the needs of each moment. The wireless control modules (3) enable the user to modify the standard comfort parameters.

The aerator device (1) of the ventilation and air conditioning system object of the invention comprises (see figure 4):

-

an outside air inlet (8) through a duct that crosses a wall,

-

a motorized gate (9),

-

a filter (10) against particles with acoustic attenuation,

-

a coil (11) air temperature conditioner,

-

an outdoor temperature sensor (12),

-

an external pressure sensor (13),

-

an electronic circuitry (14) that receives digital signals from the wireless control module (3) of the room and communicates with the vacuum device (2) through an electrical circuit that powers the aerator device (1),

-

connections (15) to the pipes through which coolant circulates,

-

a condensate tray (16) in case of humidity and temperature conditions that could cause condensation of water in the coil (11),

-

an outlet for the evacuation of condensates to the sanitation of the house with an automatic evacuation valve, and

-

an air outlet (17) direct to the indoor environment.

The outlet for condensate evacuation is only necessary in areas prone to moisture.

5 Another embodiment of the aerator device (1) further comprises a second air inlet

(18) of the dry room (7) for situations in which, when the ventilation flow has been fulfilled, the treatment of recycled air from a dry place (7) is more energy-efficient than the increase from the outside air.

10 The aerator device (1) is a compact box-like device, of a certain stiffness and finish, placed on the inner face of the facade wall.

The vacuum device (2) comprises (see figure 5):

-

an air inlet (19) for each of the wet rooms (6), each with its motorized gate (9) to regulate the proportion of the flow rate between them,

-

an air inlet for the fume hood (20) of a wet room (6), which includes a grease filter (21),

-

a coil (22) with cooling fluid through which the total flow drawn by

all air inlets (19), to capture heat in summer and to dissipate heat in 20 winter, from the air that is expelled,

-

a condensate tray (23) under the coil (22) with the relevant drain with mechanical valve and connection to a sanitation network,

-

a fan (24) following the coil (22), responsible for expelling the air from the humid rooms (6) outside,

25 - a compressor (25) of primarily silent modulating flow type spiral or scroll, with four-way valve,

-

sensors (26) for indoor smoke and relative humidity contamination,

-

sensor of presence of people as a possible cause of polluting activity,

-

an air outlet to the outside (27).

Between the coil (11) of the aerator device (1) or the coils (11) of the aerator devices (1) and the coil (22) of the vacuum device (2) a closed circuit (29) is established for the cooling fluid moved by the aforementioned compressor (25), said closed circuit (29) also being formed by the pipe for the fluid in the gaseous state (4) and

35 through the pipe for fluid in liquid state (5).

The power of the coil (11) of the suction device (2) must be equal to the sum of the powers of the coils (11) of the aerator devices (1).

With the mechanical valve placed in the drain of the condensate tray (23), 5 prevents the passage of bad odors from sanitation when siphons dry conventional.

The fan (24) of the vacuum device (2) is preferably centrifugal type due to its relatively higher pressure, also the fan (24) is responsible for expelling the outside

10 air from the humid premises (6). This air that is expelled is the total air that moves in the house when there are no natural ventilation conditions. In this air the energy from the coils (11) of the aerating devices (1) is captured or dissipated.

15 It is possible that the air is expelled from the vacuum device (2) to a collective duct (see figure 7), in this case a motorized gate (9) is necessary after the fan (24) to prevent plasters caused by the air driven to the collective duct by other users in the event that the fan (24) of the vacuum device is stopped.

20 The format and location of the vacuum device (2) are not decisive, the simplest format of the aerator device (1) is its configuration as a kitchen cabinet that can increase its volume in the case of including a hot water cylinder sanitary (31). The domestic hot water tank (31) can also be an element

25 independent of the aerator device (1) itself.

The container material would normally be sheet metal without ruling out other options that provide sufficient rigidity.

30 The aspiration device (2) requires a regulation for its operation, said regulation is done through an electronic management system (30) supplied with 230 V of the electrical installation.

The electronic management system (30) of the vacuum device (2) is embodied in solid-state electronic plates 35, and includes at least the following features:

-

touch screen (32) touchscreen or with control buttons,

-

control of the cooling / heating regime by means of the four-way valve,

-

control of the necessary power at any time with the compressor (25),

-

fan air flow control (24) for ventilation / conditioning by

frequency inverter medium 5 - smoke and relative humidity sensors (26),

-

a pressure probe outside,

-

data exchange with the aerator devices (1) through the power supply line,

-

possibility of internet connection for programming and external control.

10 Another alternative to the vacuum device (2) described is a model that incorporates a second outside air inlet (33) for situations where the energy efficiency of the outside air is greater than using the indoor air from the aerating devices ( one). An installation with this type of vacuum device (2) needs

15 necessarily the use of aerator devices (1) that recycle the indoor air.

The wireless control module (3) is a remote control device that is used in each dry room for the control and control of its environmental conditions, using the wireless control module (3) the thermal and quality conditions of the air of the

20 rooms and data on thermal conditions and air quality are collected at all times. In both cases the wireless control module (3) communicates wirelessly with the aerator device (1) of the dry room, which in turn communicates through the power line with the vacuum device (2) of the installation.

25 In the ventilation and air conditioning system of a dwelling, the joint operation of the aerator device (1) and the vacuum device (2) together with the conditions controlled with the wireless control module (3) provide the desired environmental conditions.

30 The wireless control module (3) must be located far from the walls of the dry room to be controlled, so that the sensors collect the data of the air around us and not that of walls or partitions.

The wireless control module (3) comprises (see figure 6): 35 -a digital electronic board (36) with emitted encoder so that it only acts on a single aerator device of the dry place,

-

CO2, VOC (38) sensors to control air quality,

-

at least one temperature sensor (39) to control natural cross ventilation,

-

at least one pressure sensor (40) to control natural cross ventilation;

-

a screen (37) preferably touch to program the system,

-

a wireless transmitter (42) to transmit the data to the local aerator device where it is located which in turn communicates with the vacuum device; Y

-

a battery or battery (41) that powers the assembly.

All this within a box of a format suitable for placing on a table and with a position that facilitates its functions of command and collection of environmental data.

Figure 1 schematically describes the process to achieve indoor air quality, with the following stages: outdoor air intake is through the dry premises (7); passage of air through aisles or distributors through passage openings (28); and extraction of the air by the humid places (6) that are the most contaminated.

The same air that ventilates the dry rooms (7) is reused to ventilate the wet rooms (6). The procedure implies that the humid rooms (6) are always in depression with respect to the dry rooms (7), which avoids an undesirable circulation of air in the opposite direction.

The ventilation and air conditioning system of a dwelling object of the invention takes advantage of natural cross ventilation when there is an overpressure in the façade where the aerator device and / or a Venturi effect on the outlet of the vacuum device (2) is housed, in which case The fan (24) of the vacuum device (2) remains disconnected.

Figure 2 schematically shows the procedure for recovering the energy of the ventilation air, which converts the ventilation and air conditioning system of a dwelling object of the invention into a renewable thermal conditioning system.

In winter, a closed circuit for the cooling fluid (29) formed by the coils (11, 22) and the pipes (4, 5), together with the compressor (25) make the outside air at low temperature, when passing through the coil (11) of the aerator device, raise its temperature to a comfort temperature. The energy of the indoor air is absorbed by passing through the coil (22) of the vacuum device, lowering its temperature to the temperature that the outside air initially had. The process would be repeated indefinitely contributing

only the energy that moves the compressor (25) that is considered renewable.

In summer the process would be the reverse simply by changing the direction of circulation of the refrigerant fluid to achieve cooling: the hot outdoor air would lower its temperature when the coil (11) of the aerator device passes through, air that would return to its outside temperature when passing through the coil (22) of the aspiration device prior to its expulsion.

The system also allows free heating / cooling, with the compressor (25) turned off, when in winter the outside temperature is higher than comfort, or when in summer the outside temperature is lower than comfort, even with the fan ( 2) off when there is natural cross ventilation.

A possible preferred embodiment of the invention is that embodied in Figures 3, 4, 5 and 6. It would be an installation for an apartment that has a dry room (7), two wet rooms (6) (kitchen and bathroom), and between the dry room (7) and the wet rooms (6) there are passage openings (28) that allow the passage of air. As can be seen in the figures, the ventilation and air conditioning system object of the invention in this embodiment has an aerator device (1), a vacuum device (2) and a wireless control module.

In another embodiment of the ventilation and air conditioning system object of the invention, the production of domestic hot water with accumulation is added. For this, a domestic hot water tank (31) is implemented in the vacuum device (2). The heating of the domestic hot water is carried out by a second condenser coil (34) that captures the heat of the air that is expelled outside. It also requires the installation of a temperature probe and an extension of the electronic board to manage its programming accessible from the screen that includes the vacuum device (2).

It can also happen that there are homes in which the transmission losses due to the enclosures were not compensated with the internal gains, in which case the mere recovery of heat between coils (11) is not sufficient to reach the comfort temperature. In this situation, an alternative is foreseen to capture heat directly from the outside air, which would imply the following variants:

-

place a second air inlet (33) in the vacuum device (2)

from the outside that allows the capture of heat from the air captured in heating conditions and also the dissipation of heat from the air captured in cooling conditions,

-

place in the aerator device (1) a second recycled air inlet (18) of the dry place itself (7) with a second section of the coil (11) and a second fan (35) that forces the movement of the indoor air for conditioning Thermal and filtered.

The heat collection of the outside air in the vacuum device (2) also serves to have more energy than that provided to improve the production of domestic hot water.

Another embodiment of the invention has been developed for houses with several dry rooms (7), that is to say with several aerating devices (2). Since the external temperature and pressure are unique, it is not necessary to repeat the temperature and pressure sensors for each aerator device (1), it is also not necessary to repeat the internal pressure sensors in all the wireless control modules (3) set that the internal pressure is also the same. The other components of both the aerator device (1) and the vacuum device (2) and the wireless control module are similar unless more thermal performance is desired in dry rooms (7): such as the possible heating demand in some and cooling in others simultaneously. In this case the modifications would be the following:

-

the aerator device (1) has a three-way valve for the closed circuit for the cooling fluid (29),

-

The vacuum device (2) has a five-way valve for the closed circuit for the coolant (29) and the corresponding electronic manager,

-

The one for the closed circuit for the cooling fluid (29) is formed by two pipes for the fluid in the gaseous state (4, 4B) and a pipe for the fluid in the liquid state (5).

Other embodiments would be those that took advantage of other energy alternatives such as photovoltaic or wind power to power the compressor, solar thermal and geothermal to use directly in the hot water tank or for the evaporator coil (11) for thermal conditioning.
