DESCRIPTION "ACCLIMATIZATION SYSTEM WITH HIGH ENERGY EFFICIENCY"

Technical Domain of the Invention

The present invention refers to an Acclimatization system with high energy efficiency, due to energy exchange occurring on a small amount of volume fluid in a direct way with or without deposit of inertia.

Invention Antecedents

One of the most frequent problems of present acclimatization is the exaggerated amount of energy used to acclimatize an area.

EP1403608 discloses one acclimatization machine based on the energetic exchange between a gas of a compressor and a fluid contained on an inertia tank, the fluid tank however having a minimal 28 liters capacity, therefore consuming a great amount of energy to acclimatize all the volume of the fluid.

The present invention differs from the one disclosed in EP1403608, once it doesn't comprise an inertia tank whereby the total fluid volume necessary to acclimatize is reduce by 80%.

Detailed Description of the Invention

The acclimatization system according to the present invention comprises: a fluid inlet with a strainer (9) on the acclimatization circuit; a pump flux generator (5) responsible for the fluid circulation in the acclimatization circuit; thermo manometers (7) at the inlet and outlet of the switch to control temperature and relative pressure in an out of the switch; a fluid outlet with strainer (10) of the acclimatization system; an expansion vase (11) to control and level the pressure of the acclimatization circuit; an electric valve of circuit derivation (12) usually closed allowing to maintain the fluid circulation even when the acclimatization circuit is deactivated;

a strainer (13) for network fluid admission, or fluid to the system, for the reestablishment of the desired pressure and volumetry.

One mechanical safety valve (14) with an exhaust tube for safety purposes against unattended increase of pressure in the circuit (3); a heat exchanger composed by the following elements: •At least two helical serpentines one inside the other, with the exterior serpentine (6) wherein the acclimatization circuit fluid circulates (3); inside this exterior serpentine (6) at least one fluid serpentine (4) is embossed, wherein the heat transmitting fluid (1) circulates, coming from a heat pump (2) responsible for acclimatizing the circuit;

In a preferred embodiment, at least one thermo-ventilator can be attached, being composed by the following elements:

Radiation cell (16);

Blowing fan attached on the back of the radiator (17);

At least one switch (18);

At least one thermostat (19);

At least one air temperature probe (20);

Electrovalve NF (21);

Variable switch for speed fan control (22);

Thermo-ventilator housing (23);

Tray/cuvette (24); and

Purge valve (25) .

The object of the present invention is an acclimatization system comprising at least a first circuit (1), inside of which a first fluid carrying heat or cold runs, coming from at least one heat pump (2), with the function of warming up

or freezing the first fluid. This first circuit is placed into a second circuit (3), inside of which, besides the serpentine of the first circuit (4), a second fluid carrying heat circulates, on closed circuit and in the opposite flow direction or not, relative to the direction of the first circuit (1), this second circuit (3) is mechanically powered by a pump fluid circulator (5), or something that replaces it. At the serpentine inlet and outlet of the second circuit (6) measures of temperature and relative pressure (7) take place in a way to control the heat pump (2) for the desired warming or cooling effect. By means of heat permutation effect, the second fluid in contact with the serpentine of the first circuit (4) will warm up or cool down depending on the desired effect and leaves to the second circuit (3) where it will dissipate by means of ventilators of high energy efficiency (8), which minimize condensation in the cooling case and prevent the relative humidity of the space to acclimatize, but yet can be used for aromatherapy, by the fact that the thermo-ventilators (8) have a tray/covet (24) under the radiation cell (16), this tray/covet (24) operating so as to trim some condensation in the cooling case and to insert water with the objective of reestablishing the relative humidity in the air in the warming case, by means of the second fluid entering into the thermo-ventilator (26), passing through a radiation cell (16) with forced air by the fan (17), exiting of the second fluid from the radiator (27) and again into the second circuit (3), passing through a certain number of radiators (8), in conformity with the area to acclimatize, coming again in direct contact with the serpentine of the first circuit (4), reading again the temperature and relative humidity (7), to indicate the expected result to the heat pump (2),

so that it provides the compensations in terms of cooling or warming up with maximum efficiency.

The preferred solution introduced hereinafter decreases significantly the amount of fluid volume. The fluid of the second closed circuit (3), with at least 22 mm, goes through a serpentine (6) with a minimal length size of 5 meters, of the first circuit (1), in which at least one serpentine is inserted in the second circuit (6), starting at 6,35 mm diameter, wherein a fluid carrying heat or cold comes from the heat pump (2), wherein an inert body can also be inserted on the serpentine of the second circuit (6), or not, with the same size, or not, of the serpentine of the second fluid (6) for flow rate control of the second fluid, of minimal 3 mm diameter.

With a set of a heat pump(s) (2) regulated for hot or cold, it gives to the fluid of the second closed circuit (3) heat by the direct contact of both circuits with the serpentines (6 & 4) .

To acclimatize the desired area, the acclimatized fluid passes by means of a pump flux generator (5) through thermo-ventilators of high energy efficiency (this solution with better conditions of dissipation), Fan Convectors, conventional radiators, radiation floors or other means of dissipation of existing energy, thus acclimatizing the desired area.

To increase the efficiency of warming / cooling a certain area, at least one thermo-ventilator (8) is used in connection to the acclimatization system, by two pipes ( one inlet (26) and one outlet (27), whose fluid carries hot

or cold, when passing through the cell (16) and with the help of a ventilator (17) is transmitted to the atmosphere. The thermo-ventilator (8) should be also connected to a power source, to provide power to ventilation (17) and switches (28) of the thermo-ventilator (8), by example the electric current of 22Ov.

One example of the mentioned switch (28) is the switch (18), which has three positions (OFF /ON_1 / 0N_2). When the switch (18) is on the OFF position, the thermo- ventilator (8) is disconnected and inoperable. When the switch (18) is on the ON_1 position it provides power to the switch (22), allowing to power up the ventilator (17) . When the switch (18) is on the 0N_2 position, it supplies switch (22) which allows operating the ventilator (17), as well as it supplies the thermostat (19).

When the switch (18) is connected on the ON_1 position, it allows the use of the thermo-ventilator (8) as a simple ventilator with variable regulated speed, without interfering in the air temperature. The switch (22) connected provides two possibilities: firstly, it allows placing water on the water tray (24) increasing atmosphere humidity avoiding the dry air sensation; secondly it places water and a fragrance on the water tray (24), such resulting not only in the increase of atmosphere humidity, but also in an aromatization which can be used on aromatherapy sessions.

On the ON_2 position, the switch (18) allows the same as previously stated, and also the use of the thermostat for air temperature regulation (19).

The thermostat of air temperature regulation (19) provides regulation of the desired air temperature, opening or closing electric valve NF (21), makes the outgoing and incoming fluid to be opened or closed. The thermostat (19) analyzes air temperature by a probe (20) .

The removable housing (23) of the thermo-ventilator (8) has the objective to protect all elements of the thermo- ventilator (8) and it includes a perforated area for heat dissipation and an open area for air inlet, protected by a particle filter, with variable designs and configurations, as desired.

The thermo-ventilators (8) can be assembled in all traditional central heating systems, placing the thermo- ventilators (8) where the traditional radiators are usually installed, connecting the incoming and outgoing pipes to the existing connections.

Besides this system, the thermo-ventilator (8), can be assembled on a conventional central heating system, as well as in any central acclimatization unit (hot or cold) that works with a closed fluid circuit.

This process has the great advantage of being ecologic because the heat power source, as well as its motorized power source are electrical and with lower power consumption than the existing market offer, taking the same acclimatizing areas into consideration. We have therefore an ecological acclimatization system.

This system can also be used on an open circuit, which can be used in the industry and on sanitation waters.

The present acclimatization system with high energetic efficiency can be assisted by solar-panels or other means of renewable energy.

On a domestic use, the application of this system on habitations which already have a conventional heating system, does not imply any alteration of the existing system, it only needs the replacement of the existing acclimatization source by the high energetic efficiency system and the traditional radiators, by the wall thermo- ventilators of high energetic efficiency (8).

On an industrial use, performed in the root system it is possible to assembly aerial thermo-ventilators (8), or on the wall, according to the areas to be included in the air flux caused by the fan (17) .

Example 1. Acclimatizing (warming up) a room or the like.

With air temperature at 14°C, and aiming for a 20°C temperature (previously being connected to the acclimatization system for warming up) . Placing the thermostat (19) at 20°C it will automatically open the electric valve NF(21) allowing the heat fluid to flow to the radiator cell (16) increasing the temperature in the atmosphere with or without the help of a fan (17) (therefore, the use of a fan will accelerate the process substantially) .

When the air temperature achieves 20 ⁰ C the _^ thermostat probe (20) detects it and automatically closes the electric valve NF(21) preventing the hot fluid to arrive at the radiation cell (16) .

When the air temperature drops (without artificial acclimatization), ±1°C, the thermostat probe (20) detects it and automatically reopens the electric valve NF (21) reinitiating the process.

Example 2. Acclimatizing (freezing) a room or the like.

With air temperature at 28°C, and aiming for a 19°C temperature (previously being connected to the acclimatization system for freezing) . Placing the thermostat (19) at 19°C it automatically opens electro valve NF(21), allowing cold fluid flow to the radiator cell (16), decreasing the temperature in the atmosphere with or without the help of a fan (17) . When the air temperature equals 19°C the probe (22) detects it automatically closing the electric valve NF(21), preventing the cold fluid to arrive at the radiation cell (16).

When the air temperature rises (without artificial acclimatization) ±1°C, the probe (22) detects it and automatically reopens the electric valve NF (21) reinitiating the process.

On the air temperature cooling process, some humidity- condensation might occur on the surrounding area of the radiator cell (16). In this case, most of the humidity will become water droplets, which will fall into the water tray/cuvette (24) by gravity action (that also can be used to aromatize the atmosphere) , the other part of the humidity returning to the atmosphere by the action of the fan (17) .

Example 3. Acclimatizing sanitary waters or other fluids in an open circuit

By opening the circuit (29) (e.g. a sanitary water tap) the flux stat (31) starts the heat pump (2), which will heat or freeze the fluid of the first circuit (1), allowing heat exchange to the circuit (29) by the contact of the serpentines of the first circuit (4) and second circuit (6). The sanitary water circuit (29) as a strainer as an inlet into the system (30), and before exiting by the system outlet filter (30), goes through a flow rate registry tap (32) .

The representation of the acclimatization system with high energy efficiency is only a non-limited example which can be subject to modifications performed by one skilled in the art, being included however in the scope of the invention, as defined by the following claims.
