As regards the development of the thermal loading, this enables the machine to operate at wide temperature differences due to the protection provided by the molecular energy regulator and the channels for absorbing initial heat. The modern technology uses pipes of very small cross-section to transport the heat transfer fluid quickly, via a special turbine for places to be air-conditioned, and in such places, the heat transfer fluid also uses a low thermal energy to bring about cooling. The hot water is produced by a reverse heat exchanger: small, powerful, very efficient and easy to open for cleaning.

Development method of central air conditioning, production of hot air, and hot water.

Technical field to which the invention relates

- The invention relates to the field of cooling, central heating, ventilation, cooking, drying, cold rooms and the production of hot water.

- Particularly for heating, cooling, ventilating, an environment (institutions, houses, housing, workplaces), for cooking food, drying

clothing, industrial drying, air conditioning, hot water production for institutions, homes, housing, workplaces in general.

State of the prior art (prior art equipment and their problems) a- Central heating with hot water:

Where water plays a role in transporting heat from the boiler to the radiators, the water circulates through a special pump in conduits in a closed circuit.

b- Central heating with steam:

It is the steam which plays the role of the element transporting the heat from the steam generator to the heaters, the steam operates in a closed circuit in this system with the use of a special system to return the water to the generators steam

c- Central heating with hot air:

It is the air that plays the role of the heat transporting element from the central boiler to the target places to be heated through special ducts. d- Central cooling (with fresh air):

Basically the system is composed of the condenser and the evaporator with the use of a fluid which moves between them in closed circuit during the operation of the system, the temperature of the evaporator decreases as it sends l through the large channels through the evaporator to the places to be cooled. Problems of the Prior Art Cooling and Central Heating Systems "Causes and Solutions". a- Central heating with hot water:

1- The presence of radiators in the old central heating system with hot water is the main concern which results in the increase in the cost of the entire system.

The omission of this radiator eliminates the problem which reduced the cost of the whole system to 80% compared to the old system.

2- In the old system we use High pressure pipes at a significant cost, the problem has been solved in the new system, Because the new system works at low pressure, On this, we have saved between 40 to 70% the cost relating to the heat transporting elements.

3- An approved qualified operator lasts from 05 to 10 minutes to spread out a heat transport pipe for the old technique while it lasts from 01 to 02 minutes for the use of the new technique. This saves us up to 80% of the value put in place. b- Central heating by steam:

Ditto for the old central heating with the use of steam dispenses the same problems as that of central heating by the use of hot water in addition to the added value of the steam generator which makes it more expensive and ditto for the proposed solutions .

c- Central heating with hot air:

1- The main specific problem of the old heating system with hot air is the size of the sections of air transport pipes which is expensive, this problem has been overcome in the new system by the use of '' a special air pump capable of pushing hot air through special ducts with a very small cross-section at least twenty times that of the old system.

2- The appearance of giant pipes in buildings is the second problem relating to central heating with hot air. Undesirable thing whose camouflage is a great acrobatics, the driving practice whose sections are smaller at least twenty times has solved the problem, it goes unnoticed and can be easily camouflaged if necessary.

3- The third problem in the old technique is to spread with difficulty the pipes transporting heat (hot air), the diameters of which are large, these are replaced by pipes with reduced diameters as already mentioned. This saves us up to 80% of the overall time of realization. d- Central cooling (with fresh air):

The old central cooling system, which adopts cooling by cold air, has the same problems as that of central heating by hot air. In addition to the consumption of a large amount of energy in this system, and has the same solutions as the hot air system.

Specificity of the new invention (Difference between the old and the new technique)

1- In this invention we find the use of the reverse gas-gas heat exchanger so that the two gases are (34) and (35) in close thermal contact in the thermal trajectory of the exchange, so that the first gas enters the heat exchanger near the outlet of the second gas, that is to say that the exchange paths of the two gases are opposite, this allows heating at high temperature which can reach or exceed 600 ° C.

2 In this invention, a unit (20) for producing fresh air with high profitability is used with the use of hot air and not electrical energy.

3 In this invention, heat exchangers (2) and (3) are used with thermal links (28) whose thicknesses are small more than five times than those used in the old techniques.

4 This invention uses a heat recuperator which is also silent.

5- In this invention, a variable pump is used in order to eject part of the air at high speed through small section pipes and another part is intended for the combustion of fuel.

6- This invention uses a single tube to transport the coolant (This tube consists of three layers: the first resists very high temperature and against oxidation, the second reinforces the first layer and the last is used for thermal insulation ) in one of the places to heat or cool.

7- This invention uses a coolant operating in an open circuit.

8- This invention uses clean and thermally sterilized outside air, as long as it is the coolant during heating.

9 This invention uses special new techniques in energy and fuel consumption to save about 25-50% of the latter, that is, fuel.

10 The dimensions of the invention are five times smaller than that of the old technology

11- The physical part is lighter and easier to install than that of the old technology

12 The techniques used in this invention are five times cheaper than that of the old technique The invention uses a molecular energy regulator and a primary heat exchanger. The latter provides protection and makes the device functional for high temperatures.

Purpose of invention

The objective of this invention is to decrease the cost of investment of central heating systems, central air conditioning, central ventilation, and to decrease the cost thereof, To activate their use for a wide use . That is to say Heating, cooling or aeration of the places to be adapted with good efficiency than in the previous technique, the new technique uses physical dimensions of the equipment that are quite small with a large production capacity and a lower energy consumption. .

The invention also aims to reduce excess energy consumption, thus having a good impact on the environment.

This invention aims to limit the household use of gases for cooking, drying or heating which will limit the accidents caused by this gas and also to facilitate the operation of industrial or household coolers.

This invention works:

Leaving the hot gases (33) in FIG. 3 which are produced by combustion, this tangentially crosses the face of the sinuous sheets (28) (of large area) which heats up and heats the air (34). ci cross tangential with the other side of the sheets to complete its path (air) (34) towards the conduits (21) with small sections. This is achieved by moving the air (34) at very high speed under the influence of a specially designed turbine (16), which allows the transport of a fairly large amount of air (34) through these narrow conduits (21). And if we activate the central cooling system this time the air before reaching the places to cool, first tangentially crosses the face of a sheet after dissipation with a fluid (this fluid at a low evaporation temperature) in its state of evaporation while being inside this unit (20).

It is a method of developing, charging, transporting and absorbing heat in the central air conditioning system, ventilating it, and facilitating the production of hot water and air drying of objects.

Explanation of the techniques used ^" method ^" :

The essence of this invention resides in a central cooling and heating system which does not use radiators, coils, or large transport channels for hot or cold air, but uses a small section pipe ( containing a layer very resistant to heat and protects the tube from oxidation) at least 20 times smaller than the old transport channels. Or better than that, use a unique technique of cooling, charging and heat transfer When the air moves according to this technique at a high speed of the absorber (20) or the heat exchanger with a sinuous path to the places to be adapted.

Under the influence of a turbine designed specifically for this role, allowing the transfer of an appropriate quantity of air through ducts with very small sections and which can be easily hidden if necessary.

To facilitate the movement of air in the installation elbows, special elbows have been designed. The latter, contains steering sheets arranged parallel with the curvature of the elbow; so as to limit the loss of kinetic capacity of the air, during an open or closed cycle.

Modern technology also improves the performance of the inverted heat exchanger (27) (with thin links (28) very close to each other). By operating it at high temperature differences by first passing the flue gases over a molecular energy regulator, then to an initial heat exchanger made of materials very resistant to high temperatures, making the system based on this technique small and powerful several times and inexpensive.

Explanation of Operation of the different parts of the device:

After giving the order to operate the device illustrated in Figure 1, the turbine (16) begins to send air, part of which is used for the combustion of fuel and the other part is sent through the heat exchanger (2) passing through the inlet (1) to transport thermal energy, its temperature rises as it enters the primary heat exchanger until it exits, re-entering the exchanger thermal (3) with a sinuous trajectory. As soon as it begins to enter the latter, its temperature begins to rise more and more until reaching the maximum, when crossing the channels (4) this is where the heat absorption of the the highest temperature will take place and will be transferred to the air; the latter goes directly to its target; Either to operate the unit (19) to produce hot water, or for the unit (20) to produce cold air to the places to be cooled through the tube (7) corresponding to the tube (21 ) to the distributor (9) as a last step. The hot air can also be directed directly to the distributor (8). As a final step, order through the cooling unit through the pipe (7). The combustion products (10) which reach their maximum temperature, pass through the molecular energy regulator (11) on their way to the heat exchanger (3) via the initial thermal absorption channels (4) . The molecular energy regulator plays a very important role because it will slow down the high energy molecules resulting from combustion, in order to balance the energy of the high energy molecules with the low energy or chemically inert molecules like nitrogen , their energy dissipates and cannot

damage the heat exchanger (3). their temperature begins to drop, Once the incursion begins in the heat exchanger (3) does not reach

the heat exchanger (2) until the temperature has not significantly decreased and continue its way in this heat exchanger (2) so that its temperature drops completely (the burnt gases separate from the water once the condensation begins) They reach approximately the temperature of the ambient environment, The water of condensation accumulates in the basin (12), and leaves by the tube (14). Carbon dioxide and nitrogen are released through the chimney stack (18), leaving the system.
