Solar heating and cooling system

  1. 1. Synergy Institute of Engineering & Technology, Dhenkanal Seminar on Solar Heating and Cooling System(SHCS) Submitted by Nikhil Kumar Reg.No-1201230235 Seminar Guide Mr. P. K. Nayak Department of Electrical Engg.SIET,Dhenkanal. 1
  2. 2. Outline of Presentation  Introduction  Why we need SHCS?  Solar heating method Active Heating Passive Heating  Solar Cooling  Combisystem  How does SHC Works  Components Of SHC  Important Component  Advantages of SHC over conventional methods  India: Innovative Solar Cooling System at Solar Energy Centre  Conclusion  Reference Department of Electrical Engg.SIET,Dhenkanal.
  3. 3. INTRODUCTION  Solar heating and cooling technology receive the thermal energy from sun and utilize this energy to provide hot water, space heating and pool heating for residential, commercial and industrial applications. These applications of SHCS reduce the dependency on electricity or natural fuels. The main function of solar system is to convert sun light into heat. the primary requirement of SHCS is to setup the light collectors with higher efficiency. Department of Electrical Engg.SIET,Dhenkanal.
  4. 4. WHY WE NEED SHCS?  Eliminating the need for electricity or natural gas.  Instead collect and use free, clean thermal energy from the sun.  An economical alternative to solar photovoltaic (PV) system.  Solar heating and cooling systems simply eliminate the need for electricity to cool or heat the air and water in a home or business. Department of Electrical Engg.SIET,Dhenkanal.
  5. 5. SOLAR HEATING METHODS The term solar system mainly defines two types of system:- Department of Electrical Engg.SIET,Dhenkanal.
  6. 6. Active Heating  This system can be used as commercial hot water as well as space heat. A space heat application involves some additional connecting hardware for space heat distribution system. Active solar heating system involve following major components:  Collectors to absorb energy  Circulation system  Storage tank  Backup heating system  Control system Department of Electrical Engg.SIET,Dhenkanal.
  7. 7. Passive Heating Passive solar heating is the least costly technique to heat home space. The main aim of this system is to kept out heat in summer and kept in heat in winter from sun light. Passive solar heating also depends on ventilation or windows provided in buildings or houses. Department of Electrical Engg.SIET,Dhenkanal.
  8. 8. Solar Cooling  Solar cooling is a technology that converts sun light heat energy into useful cooling of buildings. The process works by using solar heat collecting and supplied this heat to the thermal cooling system, to generate chilled water. Department of Electrical Engg.SIET,Dhenkanal.
  9. 9. Combisystem  A solar combisystem provides both solar space heating and cooling as well as hot water from a common array of solar thermal collectors, usually backed up by an auxiliary non-solar heat source.
  10. 10. How Does SHC Work?  SHC systems trap the heat from the sun (solar radiation) and transfer the heat to water or air for use as thermal energy. While both SHC systems and solar photovoltaic (PV) systems involve collector panels , they are very different technologies. Department of Electrical Engg.SIET,Dhenkanal.
  11. 11.  Collectors to take the heat from the sun and pass it to a fluid  The heat transfer fluid which takes the heat from the collector for use or storage  Heat exchangers to transfer the heat from the fluid to a home’s domestic water.  Pumps to move the fluid through the collector and/or the exchanger, and sometimes to move the domestic water through the other side of the exchanger.  Controllers to run the pumps when there is collector heat available.

  13. 13. Advantages of SHC over Conventional Methods  SHC reduced the conventional heating and cooling cost up to 35-40%.  This system helps by providing employment to establish SHC system.  Direct reduction can be made by using SHC system.  Combination of heating and cooling easily available for all type of back up heat source.  Energy sourced easily available in maximum quantity.  Collectors are used can be recyclable. Department of Electrical Engg.SIET,Dhenkanal.
  14. 14. India: Innovative Solar Cooling System at Solar Energy Centre Department of Electrical Engg.SIET,Dhenkanal.  The Solar Energy Centre in Haryana State can now score with a new and innovative solar air conditioning demonstration system: Developed by Thermax, one of India’s leading waste heat recovery and cooling manufacturers, the system with a 100 kW cooling capacity has an integrated triple-effect Vapour Absorption Chiller (VAC) and solar parabolic concentrators.
  15. 15. Conclusion Solar heating and cooling system reduce the operating cost as compare to conventional methods. Efficiency of conventional method of heating and cooling can be increased 35-40%with the help of solar heating and cooling system. The main consideration will be to reduce the initial cost of the system in future. This system provide healthy environment to the employee in industries by heating and cooling mechanism.
