  10. Recovery
    To remove refrigerant in any condition from appliance and appliance and store it, in an external container or isolate it in a portion of the system.
  11. Recover and Reuse
    Uncontaminated recovered refrigerant may be reused in a unit from which it was removed or another unit that is owned by the same owner.
  12. Recycle
    To clean refrigerant for reuse by separating oil from the refrigerant and removing moisture by passing it through one or more filter dryers.
  13. Reclaim
    To process refrigerant to a level equal to new product standards as determined by chemical analysis and must meet standards set forth in ARI-700.
  14. November 15, 1993
    Recovery and recycling equipment must be certified and labeled by EPA standards.
  15. Recovery System Dependent
    Captures refrigerant with the assistance of a pump from the appliance.
  16. Recovery Self Contained
    Draws the refrigerant out of the appliance using the appliances compressor.
  17. evacuation essentials for accurate readings & speed
    • vacuum lines should be equal or larger than the pump intake connection
    • the piping conn. to the pump should be as short as possible and as large as diameter as poss.
    • the system vacuum gauge should be connected as far as possible from the vacuum pump
  18. the 4 compo-nits of the refrigeration system?
    • compressor 
    • condenser 
    • metering device
    • evaporator
  19. ozone,  o3 is made up approximately of what?
    78% nitrogen 21% oxygen 1% other gasses
  20. what is the weight / pressure of atmosphere at sea level?
    14.696 lbs per square inch
  21. what is the measurment in (HG) mercury at atmospheric pressure
    29.92 (HG) inches
  22. effects of vacuum pressure
    increase in pressure
    lowering the pressure
    • increase boiling point of the liquid
    • lowering the boiling point of the liquid
  23. vacuum is read in inches of mercury to 29.92 (HG)

    10,000 ozone molecules
  29. what characteristics of cfc make them  more likely to reach the stratosphere than most other compounds containing chlorine
