Abstract

The invention relates to an environmentally-friendly automotive air-conditioning system comprising a device essentially formed by containers having insulating characteristics or properties. The invention, which includes air supply and discharge ducts and a turbine exhaust fan, uses the suction effects of the fan in order to force air through inner grooved ducts and ice and/or water provided in the containers, such that the air wets an 'excelsior' or 'cool pad' filter, thereby supplying cold and/or fresh air to the passenger compartment of a motor vehicle or similar using a process in which the air is cooled gradually and in steps as it passes through the ice and/or water. The system can be installed inside the body of a vehicle and does not require any fuel or gas.

Description

ECOLOGICAL AUTOMOTIVE AIR CONDITIONING SYSTEM

OBJECT OF THE INVENTION

The present invention relates to equipment consisting basically of two containers with insulating characteristics, which provided with an integrated extractor and turbine or fan, provides cool and / or fresh air to the cabin of a car or similar vehicle, by means of the use of ice and / or water, without the need for a gas compressor and other equipment that has been used to date, thus eliminating the high costs of such equipment and particularly the increase in fuel consumption caused by its use, regardless of the elimination of the increase in fuel consumption and do not use any type of gas, there is no impact on the environment.

BACKGROUND OF THE INVENTION

In the automotive field, a cooling or cooling system is traditionally used as a comfort equipment that, by means of a gas compressor, causes the latter to cool it, which by means of the appropriate ducts and a fan conducts the cooled air to the passenger compartment. The aforementioned system is extremely effective, presenting only the disadvantages that it "consumes" engine power, causes greater fuel consumption, its cost is considerable and its use affects the environment due to the referred higher fuel consumption and the use of gas, regardless of the fact that in some cars virtually no such system or equipment was offered, even optionally. Such is the case of the Volkswagen sedan car, apart from other brands, that although they offered refrigeration system as optional equipment, its high cost determined and determines that said system was not installed in the vehicles. The cooling system proposed by the invention has been designed to provide the user with very low cost equipment, extremely simple in operation, with virtually no maintenance costs, extremely simple installation, its use does not decrease the engine power nor determine increase in fuel consumption and does not generate any impact on the environment.

DESCRIPTION

In summary, the proposed system consists of a main rectangular container (1) that can be made of various materials such as polyethylene plastic, fiberglass, foil, etc., properly sealed, lined inside of thermal or insulating material, in which through its upper front part enter two tubes (2), which by means of an "elbow" of 90 degrees integrate an L-shape, those that reach the bottom of the container in appointment and through the "elbow" are projected in shape transverse (3) forming a kind of cross and are provided with holes or grooves around it in the part corresponding to the bottom or "floor" of such container (1), through which air enters the container (1), which is aspirated from the outside by an exhaust fan with air turbine (4), which in turn has two pipes or outlets (5) that will enter almost to the bottom of an auxiliary container (6) also properly sealed and lined inside of material ai On the other hand, the one that, in its upper part, carries two tubes (7) which, by means of the appropriate ducts, carries the air to vents located in the convenient places of the passenger compartment of the vehicle and by virtue of which such containers (1) and (6) are provided with ice through doors (12) and (13) located in them, the air, when circulating through them, is already introduced cold to the cabin. It should be mentioned that in the lower part of the air extractor (4), inside the main container (1), a filter (8) of "exelsior" or "cool pad" is installed, (which is used in air conditioners domestic), which allows, even when the ice melts, the outside air when circulating through the water, enters the cabin fresh, in a manner analogous to that of the domestic "air conditioners", since as is known, in These, a water pump moistens the "exelsior" or "cool pad", which through a fan circulates the air through it, bringing fresh air to the rooms. In the proposed system, such humidity, when the ice is partially or totally consumed, is produced and carried, by means of the suction produced by said extractor (4), to the mentioned filter (8). The auxiliary container (6) is located in the immediate rear part of the main container (1) - TO -

It should be noted that the ducts or tubes (2) that enter air from outside to the main tank (1), have a curved shape, equivalent to that in plumbing is known as "trap", which has the function, in the sinks as example, to prevent the entry of unpleasant odors from drainage, a curve that, in the case, is supplied with water caused by the thaw that originates in the auxiliary container (6) through a hose (14), which in the proposed system It has the function of determining a first air cooling step, which subsequently reaches the main tank (1), in which a second reduction in air temperature is obtained, which enters the auxiliary container (6) quite cold. , in which a third cooling phase is obtained, which by means of the corresponding outlet pipes (7) transfer the air to the cabin. The aforementioned determines the optimization of the ice used, greater degree of cooling and more amplitude in the lapses of supply of the containers.

It should also be noted that the main tank (1) is provided with a manual drain key (9), as well as a drain hole (10), located in an appropriate manner, which allows, by gravity, the eviction of the water that can reach To be over. In the same way, the curved tubes that provide outside air (2) are provided with another hole (11) that has the same function. Both the drain wrench and the holes (10 and (11) are provided with hoses (15) that carry the drained water, as well as the excess, to the outside, using the holes for which the car is provided for that purpose It is used as an example, which is a Volkswagen brand car, sedan type, which are located in the front of the trunk, below the place for the spare tire.

Both the main container (1) and the auxiliary ((6) are provided in its upper part with a lid or door (12) and (13) that allows the supply of ice to said containers. It should also be mentioned that the inlet tubes of air (2), the exhaust pipes or ducts (5) of the extractor and the outlet pipes (7) of the auxiliary tank, are or are sprayed with a thickness of two centimeters, and because of the described system used as an example for a Volkswagen sedan car, in this also the inside of the trunk lid is covered with polyurethane coated with a thickness of two centimeters. In cars of another type, the equipment is basically the same, adapting only the dimensions of this one due to the requirements of size and design, as well as the place where the air intake tubes (2), outlet pipes get air (7) of the auxiliary container and drain hoses (15).

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, this description is accompanied, as an integral part thereof, two drawings in which with an illustrative and non-limiting nature, has represented, as an example, a Volkswagen sedan car, the following

PREFERRED EMBODIMENT OF THE INVENTION

(OR BETTER METHOD KNOWN TO CARRY OUT THE INVENTION)

The main tank (1) is a rectangular polyethylene plastic container 03 millimeters thick, which can be made of various materials such as polyethylene plastic, fiberglass, foil, etc., coated or lined inside with polyurethane. with a thickness of 2.5 centimeters, which measures 45 centimeters wide, by 40 centimeters long and 17 centimeters high on its front and 20 centimeters on its back, which determines that the bottom of such a deposit leads to a decline towards the part front and in its upper part a rectangular supply door (12) 10 centimeters long by 20 centimeters deep and of the same material and with the same coating of the tank in appointment. It is insisted that the main tank (1) and the auxiliary (6), as indicated above, can be made of very different materials, in the case indicated in an illustrative and non-limiting manner, the polyethylene plastic by virtue of its low cost and for having been used, precisely for reasons of cost, in the development of the prototype.

On the back, through the "cover" or upper part of the main tank (1), the air extractor with turbine (4) of 12 volts, 8 to 9 amps of current, equipped with a 30-blade turbine is installed , of 2500 revolutions per minute that can decrease according to a four-step or speed current switch equipped with a rheostat for such a decrease, which for this purpose is installed on the vehicle dashboard, leading to the bottom of said extractor (4) , inside the tank (1), a filter (8), consisting of a rectangular plastic mesh of 12 centimeters per side, which inside is provided with material known as exelsior "or" cool pad ", (same which is used in domestic air conditioners), which is fixed with a "light" or distance of 5 centimeters from the top or top of the tank (1), which allows it to concentrate by means of the humidity that in such filter (8) is concentrated by the suction caused by the extractor (4), it is ge Nere more cooling in the extracted air. At the bottom of the extractor (4), the tank cover is provided with a circular opening of 10 centimeters that allows the suction of air through the filter (8). The mentioned L-shaped inner tubes (3) consist of pipe of material known as PVC, which are obtained in the market with a measure of two inches in diameter, which in its upper part are smooth and in its horizontal part that goes at the level of the lower part of the tank (1), are provided of 10 holes or slots each, which allow the distributed circulation of air through ice and / or water.

The air intake tubes (2) are also made of PVC, two inches in diameter, provided with conductive joints or "elbows" that allow them the curved shape in which at a height of 5 centimeters from the most part Below the curve is its drain hole (11). Said air intake tubes (2) have their beginning and obtain the air from the interior of the vehicle, for which two holes are made in the floor of the trunk of the car (Volkswagen), which prevents hot air from entering outside and they allow their recirculation, and therefore more efficiency in the operation of the described equipment since this determines more conservation of the cold or fresh air. To facilitate the installation of the inlet tubes (2), the outlet tubes (5) of the extractor and the outlet tubes (7) of the auxiliary tank, it is feasible to use flexible hose of the same diameter. The air inlet tubes (2), the outlet tubes or ducts (5) of the extractor and the outlet tubes (7) of the auxiliary tank, are lined by their outer polyurethane foam with a thickness of two centimeters, and in reason that in the described system the one corresponding to a Volkswagen sedan car has been used as an example, in this one also the inner part of the trunk lid is covered with polyurethane sprayed with a thickness of two centimeters.

As far as the auxiliary tank (6) is concerned, it is a rectangular polyethylene plastic container of 03 millimeters thick, coated or lined inside of polyurethane, with a thickness of 2.5 centimeters, measuring 35 centimeters wide, by 20 centimeters long and 25 centimeters high at the front and 20 centimeters at the back, which determines that the bottom of such a tank leads to a decline towards the front. It enters two tubes (5) or ducts from the air extractor (4), which are going to give 4 centimeters from the bottom of the auxiliary tank (6) and from this the exit tubes (7) that are going to give are projected to the cabin Said tubes (7) have a penetration of four centimeters in the upper part of the auxiliary tank (6). Both the main container (1) and the auxiliary ((6) are provided in its upper part with a lid or door (12) and (13) that allows the supply of ice to said containers. It should also be mentioned that the inlet tubes of air (2), the outlet pipes or ducts (5) of the extractor and the outlet pipes (7) of the auxiliary tank, are lined by its outer polyurethane, sprayed with a thickness of two centimeters, and because the system described has been used as an example for a Volkswagen sedan car, in this also the inside of the trunk lid is covered with two-inch thick polyurethane. In other cars, the equipment basically it is the same, adapting only its dimensions due to the size and design requirements, as well as the place where the air inlet tubes (2), outlet tubes (7) of the help vessel get air ar and drain hoses (15).

Both the main tank (1) and the auxiliary (6) are fixed or secured from the "floor" of the trunk, by means of screws that go from said "floor" to the top or "cover" of the tanks in appointment, carrying two screws in each of the side walls or sides of both tanks, thus excluding the front and rear of such fixing.

The air extractor (4) is fixed in its place indicated, using stainless screws and inlet tubes (2), the exhaust pipes or ducts (5) of the extractor, as well as the outlet tubes (7) of the tank Auxiliary (6) do not require any type of fixation, except for the specific glue for PVC pipes that they carry in the conductive parts, for example, in the "elbow" that joins the air inlet tubes (2) with the inner tubes ( 3), being that these tubes (3) are the only ones that must be "glued" or fixed with silicone to the bottom of the main container (1) and in the part where they join when forming the kind of cross already described.
