  42. 42. Heat Recovery • 4 Methods of Heat Recovery Flat Plate Heat Exchangers Enthalpy Wheel Heat Recovery Coils (Run Around Loop) Heat Pipes
  43. 43. Heat Recovery • Flat Plate Heat Exchangers – Aluminum plates are ribbed or dimpled – Plates stacked to create adjacent air flow passages – Operation • Two air streams pass in close proximity without mixing • Sensible energy is transferred through plates
  44. 44. Heat Recovery • Flat Plate Heat Exchangers • Advantages: – Low maintenance • No moving parts • Wider air passages – Reduced fouling risk – Lower pressure drop – Higher efficiency than heat pipe – Less expensive than pipes, wheels – Consistent performance over time – Easy to clean and inspect • Disadvantages: – Lower efficiency than heat wheel – Sensible energy transfer only
  45. 45. Heat Recovery CUSTOM ERU W/ FLAT PLATE HEAT EXCHANGERS Flat plate HX Compressors Exhaust fan Filter Outside Air Return Air Filter Heat Pump Coil Supply Air 100”h x 84”w x 195”l Side Elevation
  46. 46. Heat Recovery CUSTOM ERU W/ FLAT PLATE HEAT EXCHANGERS
  47. 47. Heat Recovery • Enthalpy Wheel – Variety of Sizes For Different Recovery Capacity – Frost Control and Economizer Options – Aluminum or Synthetic Construction • Advantages: – Higher efficiencies (70-80%) than pipes or plates – Latent transfer capability • Disadvantages: – Higher maintenance – Higher risk of fouling – Odors/other contaminants can be reintroduced to the space (especially nicotine) – Particulate matter can be reintroduced to the space – Due to leakage/purge, fans must move 10-25% more air
  48. 48. Heat Recovery • Enthalpy Wheel
  49. 49. Heat Recovery • Heat Recovery Coils (Run Around Loop) • Two coils are piped in a loop – One coil in cold air stream – One coil in warm air stream • Liquid coolant circulated with pump between coils • Advantages: – Supply and exhaust air stream need not be together – No possibility of air streams to cross contaminate • Disadvantages: – Lower efficiency than pipes, plates, wheels – Higher total costs – Pump consumes energy – Glycol required to prevent freezing – High FPI required to achieve moderate efficiency • Higher pressure drops • Prone to fouling
  50. 50. Heat Recovery • Heat Recovery Coils (Run Around Loop) • Example: – 21,000 CFM ERU – Brought into building through freight elevator – Fit into freight elevator - Max dimensions of 76”H x 76”D x 36”W – Split into 10 pieces and 2 remote condensing sections – Run around coil for energy recovery – 4 circuit, 8 stage, 128 ton water cooled condenser – HW heating
  51. 51. Heat Recovery • Heat Recovery Coils (Run Around Loop)
  52. 52. Heat Recovery • Heat Pipes – Refrigerant sealed in finned tube coil – Coil split between warm and cold air streams – Operation • Refrigerant evaporates and condenses to transfer energy Vaporous refrigerant is condensed by the cold air Condensed liquid flows back to warm side Liquid refrigerant is evaporated by the warm air Cold air is warmed by condensing refrigerant Warm air is cooled by evaporating Sealed tube,tilted refrigerant filled with refrigerant
  53. 53. Heat Recovery • Heat Pipes • Advantages: – Side-by-side air flows (better in certain applications) • Disadvantages: – Uses refrigerants • Possibility of refrigerant leakage – Tight fin spacing • Higher pressure drops • Higher risk of fouling – Lower relative efficiency than wheels and plates – Sensible energy transfer only – More expensive than plates, comparable cost to wheels
