DESC:FIELD OF THE INVENTION
The present invention relates to a power-comfort optimizer system built-in with ceiling fan more specifically the system integrating an air conditioner for reducing power consumption and providing a thermal comfort to occupants in a room.

BACKGROUND OF THE INVENTION
For many years, ceiling fans have been widely used to provide a cooling function to consumers in cost effective way. Ceiling fans create a “downdraft” by pushing rising hot air back down. Downdrafts reverse the typical direction of air movement. Instead of heat rising, it pushes back down. Then, cool air rushes in to fill the vacuum created by the absence of hot air. The ceiling fan’s downdraft is how it circulates air. Hot air continues attempting to rise even while a fan is on, and the fan’s operation continues to push it back down. The warm air rises, falls, and tries to rise again, circulating throughout the room.

Controlling such cooling function of existing ceiling fans is complex and cumbersome for the user, with such fans having limited incremental features. Ceiling fans offer cooling and lighting functional features which are usually operated by one or more pull chains and/or by a remote control. Such cooling feature typically includes several speeds: high, medium, low and off.

Further improving the user’s comfort level, air conditioners were introduced. They are functionally different from fans, because fans don’t actually cool air, but only make it feel cooler by moving it around. The advantage of air conditioners is that they increase comfort levels during hot weather.

Most people use air conditioners to stay more comfortable in their homes or offices during hot and humid summer weather.
The major advantages of air conditioners are, under extreme conditions, air conditioners may keep elderly and other vulnerable people safer from heat-induced health problems. Air conditioners are used in many commercial settings not only for increased comfort but for decreasing heat stress on delicate machinery such as computers.

But, the air conditioners use a lot of electricity. This creates both financial disadvantages for the people who have to pay for the electricity.
So, there is need for a control system to control the fan as well as air conditioner to provide comfortable user experience as well as for achieving financial advantages.

The main object of the invention is that suitable amount of air movement coupled with a suitable air temperature create the best comfort level to the user.
Generally, air conditioners are very good in creating suitable air temperature but not in creating suitable amount of air movement. When there is insufficient air movement people will tend to reduce air temperature to compensate. Conversely, when there is too much air movement you are probably wasting energy and creating discomfort.

Therefore there is a need for a fan control system to couple air conditioner with the ceiling fan to create the best comfort in the most energy efficient way. The system should ensure a suitable speed and volume of air movement evenly distributed inside a room. With an effective fan control system effectively controls the energy consumption without compromising thermal comfort.

OBJECT OF THE INVENTION
An object of the invention is to provide an automatic control system in the ceiling fan for controlling the ceiling fan and air conditioner for enabling the suitable air movement with respect to corresponding air temperature.

Another object of the invention is to save the electricity by controlling the fan and air conditioner automatically with respect to ambient temperature.

Yet another object of the invention is to provide a system in the ceiling fan and enable control of air conditioner wirelessly thereby simplifying the assembling process and reducing the cost requirements.

Yet another object of the invention is to provide a method for continuously optimizing the temperature and the speed in tandem and perform at an optimal operating point or comfortable user preferred limit.

Yet another object of the invention is to integrate the control system’s electronic component in the ceiling fan’s PCB board while manufacturing thereby simplifying the manufacturing process.

Yet another object of the invention is to configure a fan motor with suitable cogging torque and vibration.

Yet another object of the invention is providing a smart remote control for controlling the ceiling fan as well as air conditioner.

Yet another object of the invention is to provide multiple motor controls such as curtain or door or exhaust fan or combination thereof.
Yet another object of the invention is to include lighting control for improving power consumption rate.

Further object of the invention is providing an option to the user to retrofit the system with existing ceiling fans.

SUMMARY OF THE INVENTION
The present invention is intended to present a solution for creating comfortable cooling experience by combining the effect of both fan and air conditioner. The proposed patent relates to a hybrid cooling system more specifically the system capable of controlling the air movement through fan and air temperature through air conditioner thereby creating the best comfort level for the user with optimized energy. The air conditioner is very good in creating suitable air temperature but not in creating suitable amount of air movement. When there is insufficient air movement people will tend to reduce air temperature to compensate. Conversely, when there is too much air movement you are probably wasting energy and creating discomfort. Therefore the proposed system is to couple air conditioner with the ceiling fan to create the best comfort in the most energy efficient way.

The proposed system integrated in the fan ensures there is a suitable speed and volume of air movement evenly distributed at human level inside a room, the air conditioner set point can be increased without compromising thermal comfort. The effective system integrated fan design saves the air conditioner’s power consumption. The PCB board design is unique which is circumferentially arranged around the static shaft of the fan and control the air conditioner through infrared sensor unit. The system further includes a smart remote or universal remote to enable the user to set the decided temperature level as well as the system allows the user to control the air conditioner as per their wish, and also eliminates the need of multiple remote controls.
