FIELD OF INVENTION: The invention relates to a ceiling trapped hot air evacuation apparatus. More particularly invention relates to a system which is helpful in expelling hot air trapped below the ceiling to produce ideal conditions for room comfort devices such as ceiling fan, air conditioner etc. BACKGROUND OF THE INVENTION: In summer season, hot air accumulates below the ceiling if roof is exposed to solar radiation. Solar radiation conducted through the roof thickness and converts ceiling into a hot surface. When cold air comes in contact with this surface, it gets heated and trapped below the ceiling because of the density difference of air (hot air flows upwards while cold air moves downward inside a room due to density difference of air).

There are other reasons also which causes trapping of hot air below the ceiling, but our invention is mainly focusing on the hot air which is accumulating below the room ceiling in summer season. Present invention will help to evacuate this hot air, which will further help to room cooling devices (like ceiling fan, air conditioner and air cooler etc.) to work efficiently or they will achieve their working efficiency very easily. In case of ceiling fan, if there is hot air trapped below the ceiling, it will blow downward during the operation of fan. This will cause discomfort in the living space. Similarly, if we are using air conditioner and there is hot air available inside the room, AC will take more time to cool the living room also, there will be an additional burden on the AC, which will further increase the load on AC. The present apparatus will help to reduce this problem, and will result an ideal condition either for ceiling fan or AC or other room cooling devices. Like exhaust fans and ceiling diffusers, the proposed device will not produce heavy suction. In proposed device, very low power fans will be used with mild suction. Due to low power fan it can be easily operated on solar power which will give this device a green feature. Device can also run on electricity and stored power in a battery by solar power. As per the size of living space, device can be of different size or we can use two units also. The device will comprise of three units; namely- indoor unit, intermediate unit and outdoor unit. Intermediate unit will be fitted with fan unit which will induce hot air from the lower part of ceiling. BACKGROUND OF THE INVENTION: The following background discussion includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. From decades, room ventilators (small window nearby ceiling) are being used for room ventilation. These ventilators provide cross ventilation inside a living area. Principally, these ventilating opening work/s on natural convection. Inside a room, fresh air enters from window or door and after getting heated escaped via ventilating window. So, living area produce a breathing phenomenon by using ventilating windows.

Conventional ventilating windows used in rooms for ventilating air are rarely being used in present day because of less efficiency due to its size and less air movement inside the room. In summer season, hot air accumulates below the ceiling if roof is exposed to solar radiation. Solar radiation is conducted through roof thickness and converts ceiling into a hot surface. When cold air comes in contact with this surface, it gets heated and trapped below the ceiling. If there is no ventilating opening available nearby ceiling, it would be difficult for hot air to escape out. So hot air starts accumulating below the ceiling. In case of ceiling fan, if there is hot air trapped below the ceiling, it will blowed downward during the operation of fan. This will cause discomfort in the living space. Similarly, if we are using air conditioner and there is hot air available inside the room, AC will take more time to cool -3- the living room. There will be an additional burden on the AC, which will increase AC load. The proposed device will help to reduce this problem, and will result an ideal condition for ceiling fan, AC and other room cooling devices. Exhaust fans are being used from decades for indoor air ventilation; these ventilating fans are common in kitchen, bathrooms and store etc. However, these fans are rarely used in living room application because of high power consumption and heavy suction which provides discomfort to the users. Ceiling diffusers are also available in market for room ventilation. These devices are installed on the ceiling and they induce room stale air and reject it to atmosphere. Special type of ceiling (fall ceiling) is being constructed to install these diffusers. Installing diffuser directly on the RCC ceiling is not recommended due to high cost of fall ceiling. U.S. Patent No. 5,050,667, entitled, Air ventilation and heat exchange apparatus, patented on Sep. 24, 1991, has developed an apparatus which exchange stale room air with fresh outside air. In this art, device is fitted with heat storing matrix along with reverse flow duct design. In this design, fan can be operated in two different positions; operating fan in such manners, flow can be achieved in desired direction. U. S. Patent No. 5,632,334, entitled Heat recovery ventilator with room air defrosting feature patented on May 27, 1997; in this art heat is being transferring between two different air flows. Defrosting of air is also being used by stale air. U. S. Patent No. 6,120,247, entitled, Room cooling fan apparatus, patented on Sep. 19, 2000; this invention relates generally to cooling and heating of circulating air in a
