Bulus konusu iklimlendirme sistemi (1), teknigin bilinen durumunda kullanilan iklimlendirme modüllerindeki fanin iptal edilmesi ile fanin monte edildigi kesit, coanda egrilerine uygun olarak yeniden tasarlanmakta ve sogutma ünitesinde (3) fan yerine hava yükseltici (6) kullanilmaktadir. Turbo fan (2) ile sogutma ünitesinde (3) yer alan hava yükseltici (6) birbirlerine basinçli hava hatti (7) ile baglanmaktadir.

TRDESCRIPTION AN AIR CONDITIONING SYSTEM Technical Field This invention is related to an air conditioning system used in vehicles and providing heating-cooling-air conditioning effect in the vehicle. Previous Technique With the development of technology, air conditioning systems in vehicles have also diversified. However, no development has been made to reduce the noise in the vehicle. Today, the noise levels of the fans used in in-vehicle air conditioning systems are high and the fans are located in the cabin. This situation is one of the factors that negatively affects customer satisfaction. In addition, the contact of the fans used in in-vehicle air conditioning systems with the air causes turbulence of the air. In this case, the efficiency of the flow decreases and the noise level increases. The power consumption in air conditioning systems used in vehicles is quite high. However, their volume, weight and costs are also high. The fans in the air conditioning modules are used only in air conditioning systems and cannot be used anywhere else in the vehicle. In the Japanese patent document numbered JPH] 1342728, which is one of the known applications in the art, a vehicle air conditioning system that works quickly, effectively and silently is mentioned. The air and smoke inside the vehicle are sucked through a suction hole in the ceiling. Then the air is thrown out through the rear exit hole with the help of a valve. If the air is desired to be cleaned, the position of the valve is changed and the air is passed through a filter, cleaned and given back into the vehicle. In the United States patent document numbered USZOlOlOO306, which is one of the known applications in the art, a system that controls the vehicle features while the vehicle is idle is mentioned. The system performs the control job with the help of the control unit and computer it contains. The vehicle air conditioning system is connected to the battery for fuel saving. The batteries provide a silent working environment for the air conditioning system. The document mentions a silent vehicle air conditioning system. Silent operation is possible by reducing the rotation speed of the cooling fan. If the interior of the vehicle is silent, the rotation speed is kept low even when the air conditioning system stops operating. Brief Description of the Invention The purpose of the invention is to realize an air conditioning system that reduces the noise level inside the vehicle cabin. Another purpose of the invention is to realize an air conditioning system in which the air accelerated inside the cabin does not come into contact with a fan wheel and a laminar silent flow is provided without turbulence. Another purpose of the invention is to realize an air conditioning system in which the engine cooling system can be operated with a side pressurizer when needed. Another purpose of the invention is to realize an air conditioning system with low power consumption compared to the air conditioning systems in the known state of the art. Another purpose of the invention is to realize an air conditioning system with reduced weight compared to the air conditioning systems used. Another purpose of the invention is to realize an air conditioning system with lower cost compared to the known state of the art. Detailed Description of the Invention "An air conditioning system" realized to achieve the purpose of this invention is shown in the attached figures; from these figures: Figure 1 - Schematic view of the air conditioning system. The parts in the figures are numbered and their equivalents are given below. Air conditioning system Turbo fan Cooling unit Serpentine Evaporator Air riser Air line Air duct 9. Blower M. Engine cabin C. Vehicle cabin The subject of the invention is the air conditioning system (1) that provides heating-cooling-air conditioning effect in the vehicle, in its most basic form, - at least one turbo fan (2) located in the engine cabin (M), - at least one cooling unit (3) located in the engine cabin (M), - at least one serpentine (4) located in the cooling unit (3) and providing the contact area of the heated or cooled fluid with the surface to be expanded, - at least one evaporator (5) located in the cooling unit (3) where the refrigerant enters as a liquid and is vaporized and withdrawn from the substance as a gas, - at least one air riser (6) located in the cooling unit (3) and pressurizing the supply air, - turbo fan (2) and the air amplifier (6) located in the cooling unit (3) - at least one air line (7) connecting each other, - at least one air duct (8) used to transmit the air coming out of the cooling unit (3) to the vehicle cabin (C), - at least one blower (9) to which the air ducts (8) are connected and which delivers the air cooled in the cooling unit (3) into the vehicle cabin (C). The air conditioning system (1) in question is redesigned in accordance with the Coanda curves, by cancelling the fan in the air conditioning modules used in the state of the art, and the section where the fan is mounted, and the air amplifier (6) is used instead of the fan in the cooling unit (3). The turbo fan (2) and the air amplifier (6) located in the cooling unit (3) are connected to each other by a pressurized air line (7). The air amplifier (6) section has a protrusion through which pressurized air can enter. The pressurized air produced by a high-speed pressurized turbofan (2) placed in the engine cabin (M) is connected to the protrusion on the surface of the air amplifier (6) via an air line (7). The pressure value of the electric turbofan (2) can be changed by the control system and the output speed of the air blowers (9) can be changed. Since the air amplifier (6) operating with the new section can absorb and accelerate air up to 15 - 18 times the supply air, the air from the vehicle cabin (C) can be absorbed and passed through the filter, heater and cooler, and the same air conditioning system (1) can be used. Since the turbo pressurizer engine and pressurizer fan are outside the vehicle cabin (C), noise does not reach the cabin. The flow created by the air amplifier (6) is a linear flow and turbulence and related noise do not occur on the accelerator. The weight and dimensions of the turbo pressurizer fan are smaller than the fans used in vehicle air conditioning modules. At the same time, they consume less energy since they work more efficiently. In the same way, if the cooling unit (3) fan is also canceled and converted to air amplifier (6), two system air flows can be provided with a single fan with a larger turbo pressurizer. This situation provides volume and weight gain and also reduces vehicle electricity consumption. With the air conditioning system (1) in question, the noise level inside the vehicle cabin (C) is reduced, since the air accelerated inside the engine cabin (M) does not come into contact with a fan wheel, turbulence does not occur and a laminar silent flow is provided. In addition, the engine cooling unit (3) can be operated with the same pressurizer when needed. The air conditioning system (1) is an air conditioning system with low power consumption, reduced weight and lower cost compared to the air conditioning modules in the known state of the art (1). TR
