FIELD OF INDUSTRIAL APPLICATION This invention relates to closed circuits of pipelines connecting heating radiators, air heaters, fan coils and heat exchangers to heated liquids, air or other bodies in a solid, liquid or gaseous state. The present invention relates to a heating system that has a heating system, and a method for rapidly increasing the temperature of equipment and machines that require heating.

BACKGROUND OF THE INVENTION According to the law of gravity, the gravitational force between the Earth and other objects is created in such a lucky way that this force, the weight of the object, becomes practically negligible at a certain distance on the surface of our satellite. decreases rapidly with distance. Because of this, astronauts float around the spacecraft. To stand in one place, they need to hold themselves indoors with a cable to the spacecraft. Therefore, since liquids cannot be poured, astronauts must drink through small straws.

The law of conservation of energy was formulated in the 1840s. This law states that energy passes from one state to another when it wants to occur, without creating or destroying anything. This law provides a close relationship between all energy states. That is, these energies include heat, light, electricity, magnetism, and mechanical and chemical energies. Albert Einstein demonstrated that any object can be considered a manifestation of energy. For example, the object turns into energy during a nuclear explosion, and the cyclotron succeeds in converting energy into matter.

Scientists now know that the atomic structure of liquid compounds is made up of molecules that are constantly moving or vibrating rapidly from one side to the other or up and down. The spacing between molecules and the way they move are
Indicates whether a substance is solid, liquid, or gas. When this material is heated, its molecules increase their kinetic energy and vibrations, causing them to move faster until they reach a temperature at which they break apart. In other words, the liquid turns into vapor.

Friction and gravity are the most natural forces that oppose this movement. The study of the relationship between pressure and regime was
It is based on Charles' law. At a constant temperature, the pressure exerted by a substance is inversely proportional to the volume it occupies. In other words, the product of volume and pressure is a constant value unless the temperature changes.

SUMMARY OF THE INVENTION It is an object of the invention to provide a method for more effectively increasing the temperature of a closed heating circuit system to which heating radiators or other heating elements can be connected.

[0007]

[Means for Solving the Problems] The above problems are solved by the present invention, in which a heating radiator, a coil or a heat exchanger can be connected, and a closed circuit system for circulating liquid can be used to create a relative vacuum or negative pressure to quickly raise the temperature. A method of increasing the temperature of a closed heating circuit system, operating with any thermal energy source, characterized by increased efficiency compared to heating under normal conditions of atmospheric pressure There is.

Further advantageous developments according to the invention are described in the dependent claims.

[0009]

Based on these physical principles, starting from two identical tanks receiving the same energy contribution, if one of the tanks is placed in a relative vacuum or negative pressure, the temperature of that tank will rapidly increase. and its efficiency becomes more effective than that heated under normal conditions of atmospheric pressure. The increase in temperature that occurs is proportional to the vacuum or negative pressure applied at any given time.

0010

[Example] The same test is carried out using a start, hold, and
Performed in conjunction with a separate pipeline to each tank using a thermostat. The expansion vessel was connected to the pressure-operated circuit, and sufficient vacuum was applied to the vacuum-operated circuit, so that a significant vacuum was maintained at the desired operating temperature at all times. The performance obtained with circuits operating under vacuum is much better than those operating under normal ambient conditions.

[0011] Any liquid can be applied to this system, but in order to obtain the best efficiency it must above all have a high boiling point value and a special specific heat. The liquid that gives the best results is a heating oil of mineral origin, which has been commercially available in Spain for several years. Its main characteristics are thermal stability, resistance to polymerization and thermal decomposition, chemical stability during use and storage, good thermal stability, no corrosion of the materials used in the system, high specific heat, high Boiling point, low solidification temperature, moderate viscosity at any temperature, neither toxic nor odorless.
It has a low vapor pressure.

According to the above description, the present invention can be equipped with a heating radiator, coil or heat exchanger for heating any liquid substance, such as an air heater or any device or machine that requires heat for its operation or operation. by connecting one or more pipelines to a tank or vessels of any size or shape using substantially any thermal energy. According to the above explanation,
In any system, the entire system must be evacuated or under negative pressure. Thus, at any time during operation, the system operates at a significant vacuum or negative pressure, but always at sea level and below atmospheric pressure (760 mm Hg).

In any closed circuit system with an interior that circulates a liquid, when a relative vacuum or negative pressure is applied, the efficiency is proportional to the applied vacuum or negative pressure because of the rapidly moving and oscillating liquid molecules. To increase. This is because liquid molecules are partially independent of atmospheric pressure. and,
This brings in more heat, increases kinetic energy, and reduces frictional forces.

[0014]

[Effects of the Invention] Therefore, according to the purpose of the present invention, a vacuum or a full negative pressure or a partial negative pressure is used, and some heating is applied, and the heat source used is not suitable for the liquid, solid, or gas to be heated. Its use in any kind of equipment that lacks it increases the efficiency of heat exchange.

At the same time, the method according to the invention improves the circulation of the liquid when used as a heat transfer body, since the kinetic energy is increased.
