PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION
[0001] The present disclosure relates to an air conditioning system for a
vehicle which blows air from seats, more particularly, to a control apparatus for automatically regulating a speed of a blower motor and duty cycle of compressor of an air conditioning system based on a position of air vent of the air conditioning system and seats of the vehicle.
BACKGROUND OF THE INVENTION
[0002] The conventional Air Conditioning (AC) system generally includes,
but not limited to, components such as compressor, condenser, evaporator, blower fans, condenser fans, thermostatic expansion valves and relevant air ducting based on the vehicle design. In case of AC system on passenger bus vehicle, or on a coach in the air conditioned train, the majority of components (condenser, evaporator, condenser fan and blower) are mounted on roof-top.
[0003] FIG. 1a illustrates a side view of a general arrangement of an AC
system (1) mounted on a roof of a vehicle and FIG. 1b illustrates a top view of the general arrangement of the AC system (1) mounted on the roof of the vehicle, according to prior art. The arrangement allows to produce cold air at the AC system (1) and flows through air duct (2) and is subsequently discharged through air vents (3) installed at each seat of the vehicle to cater the air flow requirement of passengers across all the seats. There are multiple air vents (3) placed over the each row of passenger seat, through which air flows out to cool the passenger environment. The air vents (3) are generally designed in such way that direction and amount of air flowing out of it can be controlled by small human effort (i. e., by adjusting the air flow vents as per occupant air directivity and discharge requirement). Also, there are certain free flowing vents which blows cold air to other parts of passenger cabin. An opening (4) is placed strategically for recirculating the air back into the AC system (1). This opening is called return air grill (location at which air is sucked back from passenger compartment to be cooled

again at evaporator). The figure also shows a small partition that may exist between a driver side cabin (6) and a passenger side cabin (7). The air which is provided to the vehicle saloon with the help of the air vent (3) is sucked back in through the return air grill and cooled/heated (as per requirement) and thrown back in the vehicle saloon, thus completing the loop. Further, in most vehicles like buses, engine or transmission system (5) is placed on rear end of the vehicle. The rows of seat at rear position are closer to the air duct (2).
[0004] In the conventional AC system (1), the overall operation is regulated
on the basis of temperature of air at return air grill, the set temperature (based on digital or analog temperature input given at dashboard system near the driver area), and on other parameters, including but not limited to, ambient temperature, ambient solar radiation levels, refrigerant high side pressure, and refrigerant low side pressure. On the basis of the above mentioned inputs and parameters, the AC operation will be regulated in ways that include but not limited to varying the total air discharge, varying the compressor speed or regulating the compressor duty cycle and a combination of these two and so on. As thermal comfort is a matter of subjective experience, passenger can control the amount of air flowing from corresponding vents of its seats. However considering the number of occupants at given time, there is a scope of improvement in operating logics to overcome the various shortcoming including but not limited to the following:
1. The AC operation controls are conventionally located in driver area, which generally has considerable higher heat load (due to engine, bigger windscreen). In such cases, for given value of set temperature, there is a possibility of driver compartment area temperature being comfortable but it may result in overcooling in passenger compartment.
2. In case of long distance journey through passenger bus, if the passengers feel overcooling they may individually adjust their air vent (3) to close or divert the air coming from the air vents (3) away from them.

However, the AC system continues to operate at the same rate leading to even more overcooling.
3. In case of buses with engine or transmission system (5) on the rear end, the rows of seat at rear position are closer to the air duct (2). This may cause overcooling at certain specific location (seats that are closer to the roof vents due floor height being grater in those reasons).
[0005] The general practice in many buses with the AC is to operate the
AC on fixed blower speed and cooling rate irrespective of the ambient condition. The passenger may close the air vent (3) when he feels cold but the cool air still flows through free flow vents. Therefore, there is a need for efficient mechanism to automatically control the AC system to overcome the above mentioned problem.

In an embodiment, the sensor (9) is integrated on the passenger seat back rest and corresponding air vents as illustrated in the FIG. 3. The back rest of the seats (11) is recline-able as per passenger comfort. Thus, the sensor (9) integrated

on back rest will able to communicate position information such as an angle of inclination with respect to a reference axis.
[0032] The controller (10) is configured to receive the position information
of each of the air vent (3) from the first sensor (8), receive the position information of each of the seats (11) from the second sensor (9), and automatically regulate a speed of a blower motor of the air conditioning system based on the position information of each of the air vent (3) and the position information of each of the seats (11).

location would be feed in the controller (10) form the sensors (8 and 9). The feedback can be filtered based on location of the seat (11) (i.e. front or back, seat placed on left hand side or right hand side). The main control unit would than calibrate the overall cooling demand based on weighted average of various feedback from different location. This cooling demand will be than communicated existing HVAC control unit to increase/decrease cooling effect and blower speed.
[0034] In order to regular the speed of the blower motor or the duty cycle

In an embodiment, the status indicates an air vent (3) in one of a fully open position, a partially open position and a fully closed position.
[0035] When the status of each of the air vent (3) is detected in one of the

close position, and some of the air vent (3) is detected in one of the fully open position and the partially open position, the controller (10) is configured to determine an angle of inclination of the seats (11) for which the air vent (3) is in one of the fully open position and the partially open position based on the position information received from the second sensor (9), determine an average of the angle of inclination of the seats (11) for which the air vent (3) is in one of the fully open position and the partially open position, determine a plurality of parameters associated with the vehicle, and automatically regulate the speed of the blower motor or duty cycle of compressor of the air conditioning system based on average of the angle of inclination of the seats (11) for which the air vent (3) is in one of the fully open position and the partially open position and the plurality of parameters associated with the vehicle.
[0038] FIG. 4 illustrates a schematic representation of air flow directivity
from the air vents (3) of the vehicle, according to embodiments as disclosed herein. Many a times when the occupant does not want cooling/heating, the occupant closes the vent or direct the vent away from him but the vents remain open. The FIG. 4 shows the representation of collecting this feedback provided by the passenger (of either closing the vent or directing it away from himself/herself). Thus, air flow reference axis (12) is direction of air flow when air from the air vents (3) is directed towards seat head rest. The difference between actual air flow directions (13) with

respect to the reference axis (12) is measured or calibrated as θ. More the value of θ lesser will be the cooling demand by that particular passenger.
