Transcript

  • 1. WELCOME TO THE WORLD OF HVAC FROM BUCC (HVAC)-MR. NEERAJ SHUKLA L&T (ECC) LTD.
  • 2. WHAT IS HVAC ?  H- HEATING  V- VENTILATION  AC- AIR CONDITIONING
  • 3. Few People think that HVAC is all about Luxury , Waste of money and Valuable Energy. BUT……………..!!
  • 4. Of Course, It is the RIGHT of every individual to live in comfort and HVAC is committed for it. ALSO, HVAC serves the Industrial Segment to great extent.
  • 5. VARIOUS APPLICATIONS OF AIR CONDITIONING  SHOPPING MALLS  AUDITORIUMS & THEATRES  HOSPITALS  HOTELS AND RESTAURENTS  OFFICES  COMMERCIAL COMPLEX  LUXURY APPARTMENTS  INFOTECH PARKS  PHARMA INDUSTRY  TELECOM INDUSTRY  AND MANY MORE………!!
  • 6. WHAT IS TR ? 1 TR IS AMOUNT OF HEAT TO BE EXTRACTED FROM THE ATMOSPHERE FOR MELTING ONE METRIC TON OF ICE IN 24 HOURS. ONE TON OF REFRIGERATION (TR) EQUALS TO 12000 BTU/HR. OR 3025 KCAL/HR.
  • 7. WHAT WE ARE GOING TO LEARN?  FUNCTIONS OF HVAC  BASIC OPERATING CYCLE  CLASSIFICATION OF AC SYSTEMS  ABOUT VARIOUS AC SYSTEMS  STEPS INVOLED IN DECIDING THE SYSTEM  ABOUT HEAT LOAD  TYPES OF COMPRESSORS  ABOUT AC EQIPMENT  ABOUT AIR DISTRIBUTION SYSTEM  ABOUT VENTILATION  RECENT TRENDS IN HVAC INDUSTY
  • 8. FUNCTIONS OF HVAC  CONTROL OF AIR TEMPERATURE.  CONTROL OF MOISTURE CONTENT IN THE AIR.  PROPER AIR MOVEMENT.  TO HOLD THE AIR CONTAMINATION WITHIN ACCEPTABLE LIMITS.
  • 9. BASIC COMPONENTS OF AIR CONDITIONING  COMPRESSOR  CONDENSER  THROTTLING DEVICE  EVAPORATOR
  • 10. BASIC OPERATION CYCLE
