FIELD OF INVENTION
The invention generally relates to cooling and heating arrangements and more particularly to a spot cooling and heating arrangement for a two-wheeler rider.
BACKGROUND
A two-wheeler is the most cost-effective mode of transportation for moderately long distances. Unlike cars, a typical two-wheeler does not have any provision for providing a suitable climate to a rider. Therefore, the two-wheeler rider often faces the problem of riding in utmost hot or cold climatic conditions. The rider usually faces such difficulty during weather conditions like summer or winter. In countries like India, riding for long distances in a motorbike during summer or winter, is a tough task due to the extreme temperatures.
To escape travelling in extreme hot or cold climates, die rider either uses a car or may commute in any other vehicle having an inbuilt Heating, Ventilation & Air conditioning system (HVAC). The use of such vehicles for travelling the same distances consumes more fuel and may create excessive pollution in the atmosphere.
The conventional cooling arrangement for the two-wheeler riders includes a cooling jacket that can be worn by the rider. The cooling jacket is connected to a system for providing a cooling effect to the jacket. However, such arrangement requires the rider to always carry the jacket along with the bike thereby reducing the comfort of travelling.

Hence there is a need for an improved cooling and heating arrangement for riders of two-wheelers.
SUMMARY OF THE INVENTION
According to an exemplary embodiment of the invention, a cooling and heating arrangement for a two-wheeler rider is disclosed. The cooling and heating arrangement may be a spot cooling and heating arrangement. The arrangement may work in such a way that a cool or a hot air may be directed on die two-wheeler rider. The flow of the cool or hot air may be directed to one or more external body parts of the rider for providing the desired cooling or heating effect. During summer seasons, the cooling and heating arrangement may be used to blow cool air on the rider. Alternatively, during winter seasons, the cooling and heating arrangement may be used to blow hot air on the rider. The cooling and heating arrangement may include a heat exchanger, a compressor, a condenser and an expansion valve. The heat exchanger may act as an evaporator for providing cooling and the heat exchanger may act as a heat pump for providing heating. The cooling and heating arrangement may provide a suitable temperature to the rider during rides thereby making the ride comfortable.

DETAILED DESCRIPTION OF DRAWINGS
The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skilled in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
According to an exemplary embodiment of the invention, figure 1 and figure 2 illustrates a side view and a partial top view respectively of a cooling and heating arrangement for a two-wheeler rider. The cooling and heating arrangement may be employed or installed in the two-wheelers such as, but not limited to, a motor cycle, a motor bike, a super bike etc. The arrangement as disclosed herein may be operated in order to provide a desired cooling or heating effect to the rider. The arrangement may further work as a spot cooling and heating arrangement such that a cool or a hot air may blow on one or more external body part of the two-wheeler rider. By way of an example, while riding during a hot climate, the cool air may be directed to blow on

flow of cool air may be directed on other body parts such as face, arms, abdomen, legs etc of the rider.
The cooling and heating arrangement may be adjusted to blow either the cool air or to blow the hot air. In other words, the rider may adjust the cooling and heating arrangement to blow cool air during a ride in a hot weather. Alternatively, the rider may adjust the cooling and heating arrangement to blow hot air during a ride in a cold weather.
According to an embodiment, the cooling and heating arrangement may be employed in the front half part of the two-wheeler. The arrangement may be positioned behind the front wheel and below the petrol tank of the two-wheeler. It will be apparent to a person skilled in the art that the position of the components of the cooling and heating arrangement may vary based on the design of the two-wheeler. It should be noted that the cooling and heating arrangement depicted in figure 1 is merely for illustrative purpose and the position of the components may vary based on the design of the two-wheeler.
The two-wheeler having the cooling and heating arrangement may include a windshield. According to an embodiment, the windshield may be moulded as a part of a headlight cover of the two-wheeler. According to another embodiment, the windshield may be mounted as a separate attachment above the headlight. The height of the windshield may be such that the windshield may cover the upper body of the rider. In other words, the windshield may divert the wind blowing towards the upper body of the rider and protect the rider from the hot or cold wind depending on the weather. The windshield may be constructed from materials or combination of materials that may include, but are not limited to one or more of plastic, glass,
polycarbonate, acrylic^plastic .and.any other suitable material! known in ih& art. As will be

appreciated by those skilled in the art, the height and design of the windshield may vary based on the design of the two-wheeler.
The cooling and heating arrangement may include an air filter. The air filter may be positioned in front of the two-wheeler below the windshield. The two-wheeler may further have an arrangement that may redirect, close, or vary the amount of atmospheric air flowing through the air filter. The arrangement for flow of atmospheric air may be at least one or more controlled spaces for air flow. The flow of atmospheric air through the air filter may depend on the speed of the two-wheeler such that the faster the two-wheeler, the more the air flow through the air filter. The air filter may purify the atmospheric air flowing into the cooling and heating arrangement when the two-wheeler is in motion.
According to an embodiment, the cooling and heating arrangement may further include a heat exchanger for providing a cooling or heating effect to the rider. For providing a cooling effect, the heat exchanger may be an evaporator having a refrigerant. The heat exchanger may be mounted on the two-wheeler and may be positioned behind the air filter. The position of the heat exchanger may be such that the purified atmospheric air passing through the air filter may flow through the heat exchanger. On flowing through the heat exchanger, the atmospheric air may transfer the heat to the refrigerant flowing within the heat exchanger and may convert into the cold air. The cold air flowing through the heat exchanger may be further directed to the two-wheeler rider for providing a cooling effect. Alternatively, for providing a heating effect to the rider, the heat exchanger may act as a heat pump. It will be apparent to a person skilled in the art, that for providing a heating effect the direction of flow of refrigerant will be opposite in the cooling and heating arrangement.

The cooling and heating arrangement may further include at least one or more blower. The blower may be arranged to blow the cool air or the hot air flowing through the heat exchanger on the rider. The one or more blower may further have an adjustment mechanism to control the flow of air blowing from the blower. The rider may use the adjustment mechanism to control the flow of air with respect to the speed of the two-wheeler. A blowing end of the one or more blowers may be connected to at least one or more vents. As illustrated in figure 2, the vents may be an opening on a dashboard of the two-wheeler that may close, open or direct the air blowing through the blower. In other words, the vents may be directed to a specific portion of the rider's body to cool or heat that portion. By way of an example, if the rider needs to feel the cool breeze at their face, they may direct the vent at their face. Similarly, if the rider wants to feel the breeze at their chest, they may direct the vents at their chest. For two-wheelers having more than one vents, they may direct each vent separately to the specific portion of the body. The cooling and heating arrangement may further have at least one or more hoses to blow the cold or the hot air passing through the heat exchanger. The hoses may be arranged on both sides of the two-wheeler. Each of the hose may have a plurality of cavities such that each cavity may be controlled to blow air to the rider from each sides of the two-wheeler. The hose may be further used by a pillion rider for having the desired cooling and heating effect.
The cooling and heating arrangement may further include a compressor. The compressor may be connected to the heat exchanger. The compressor may compress the high temperature refrigerant flowing from the heat exchanger to the compressor and may convert it into a high pressure and high temperature refrigerant vapour. The high pressure and high temperature refrigerant vapour may further flow into a condenser. The condenser coil may be in contact with the atmospheric air. The atmospheric air flowing through the condenser may cool the p .refrigerant rand.Huay condense [the refrigerant. yar^ur^intOQa^liciuid^refrigejant. The liquid'

refrigerant may further flow into an expansion valve where the temperature and pressure of the refrigerant may be further reduced to cool the refrigerant further. The expansion valve may be connected to the heat exchanger thereby completing the cooling and heating circuit.
