3. ABSTRACT
• Development of Renewable Energy to meet the growing energy demand.
• Nowadays usage of Air conditioner is more. So, the load demand is
increasing day by day.
• In recent days the progress on the solar based Air conditioner has
increased.
• Therefore, this project focus in the implementation of DC motor in Air
Conditioner integrated with Photo Voltaic system which consists of PV
panels, charge controller, inverters and batteries.
• The solar energy is renewable and eco friendly.
• Instead of using AC motors in the Air conditioner, DC motors are used
for reducing the Power Consumption.

4. OBJECTIVE
• Using of DC motor instead of Induction motor in the Air conditioner
• Linear speed control to be done .
• To improve the working of system using a batteries with charge
controller for controlling the charging of batteries.
• This system to be run the Indoor unit even the power cut ,it will
work as fan and can use for other load also.

Daut eta al “ Solar Powered Air Conditioning System” (2013),ELSEVIER
International Conference, Energy Procedia 36(2013)
• This research work explains the solar power used for Air Conditioner
System but the controlling process is not takes place and they used
AC motor is a drawback for this system and speed control is not
used these are the draw backs of this system
Habib Ben Bacha eta al “Air Conditioning By Solar Energy”(2003)

• This research work explains a detailed survey and description of a new
solar -based air-conditioning technique using a solid adsorption system
• But this system not gives a power consumption less and accurate
controlling process

Controller”(2013),International Journal of Scientific Research.
•This Research work explains the control of air conditioning system
such that the output temperature of air conditioning systems are getting
as required by the operator with fast response and low consuming power
•But this system only doing a control process not there power
consuming so this is drawback of this system

7. DRAWBACKS ON EXISTING SYSTEM
• The regulating of speed of Air conditioner is difficult it is regulated
in switching step by step not in fine tuning
• Power consumption is high
• During the normal operation the room temperature gets certain level
,the air conditioner will cut-off after sometime the air conditioner will
run this operation repeats more than 100 times per day for 24hrs running
of air conditioning system
• By using AC motors in the Air Conditioner causes a starting takes
the high load current comparing to DC motor .

10. MERITS OF PROPOSED SYSTEM
• Power consuming is less comparing to existing system
• Speed control is finely achieved
• using of charge controller to sense when the batteries are fully charged
and to stop, or decrease, the amount of current flowing to the battery due
to this battery not drain fast
• High efficiency comparing to existing system.
• if the power cut is occurs the outdoor unit is only off but the
indoor unit the blowers are rotates so the air ventilation will got so
the people can satisfy there needs
• if Air conditioner not in use ,the battery can use for other needs and
load also.

11. PHOTO VOLTAIC CELL
• Photovoltaics (PV) is a method of
converting solar energy into direct
current electricity using semicond
ucting materials that exhibit the
photovoltaic effect.
• Here the two panels are connected
series and this terminal is given to
charge controller to avoid reversal
action
2/24/2016 SAEC/EEE 11
12. CHARGE CONTROLLER
• It controls the flow of electrons from
PV panel to the Battery
• It increases the Battery efficiency
• It work depends on the pulse get from
the multi-vibrator circuit
• It decides the flow of electrons to
battery and it avoids that battery heating
during charging time
• It control the flows of electrons from the
PV panel to the battery by switching of
the MOSFET by square pulse from the
multi-vibrator circuit

14. FEATURES
• The PIC controller 16F877A is used to get the analog value of temperature
through the temperature sensor and this values is convert to Digital by the
Inbuilt ADC( Analog To Digital Converter)
• The MAX232 IC is used for interfacing a PC and Controller by using
RS232 communication and data is viewed by the MS-Visual Basic.
• The temperature sensor is given to analog port of the Controller
• There are five ports in the controller and Port A and E are analog and Port
B,C,D are Digital, Its operating voltage and frequency is 5V and 10Mhz
2/24/2016 SAEC/EEE 14
16. FEATURES
• The main working is to converts digital messages to analog values by
DAC0808 IC
• External temperature and temperature setting is controlled and signals are
compared and given to the controller through the DAC board
• Remote setting value is given in PC and temperature sensor value is given
to the Controller and Comparison the values given to the DAC
• In this board consists of two Op-Amp to increasing the gain of the Op-
Amp. 1st op-amp acts as I to V converter, 2nd op-amp acts as voltage
follower

17. PMDC MOTOR
• Working principle based on the fact that whenever a current carrying
conductor is placed inside a magnetic field , there will be mechanical force
experienced by that conductor, No need of field excitation arrangement.
• No input power in consumed for excitation which improve efficiency of dc
motor.
• No field coil hence space for field coil is saved which reduces the overall
size of the motor so it will reduce the size of the indoor unit
• Cheaper and economical for fractional kW rated applications.
• Fine tuning is achieved

19. FEATURES
• In this dual power supply board the three voltage regulators are connected
IC7805,IC7812,IC7905
• This board consists of full wave bridge rectifier due to higher efficiency
comparing with half wave bridge rectifier
• The 15volt taken from the 230V/15V transformer is given to bridge
rectifier and it is filtered with capacitor and voltage regulator and can use
the power supply to various boards
• This 7805 represents ‘78’ means positive and ‘05’ means +5V and 7812
means +12V and 7905 means negative 5V
