• 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
Heat Recovery
![Page 44: HTS Engineering Company Presentation by Evan Miller](https://reader036.vdocument.in/reader036/viewer/2022062512/554a7e99b4c90568288b5175/html5/thumbnails/44.jpg)
• 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

• 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

• 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

• 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

• Heat Pipes– Refrigerant sealed in finned tube coil
– Coil split between warm and cold air streams
– Operation
• Refrigerant evaporates and condenses to transfer energy
Warm air is cooled by evaporating
refrigerant
Cold air is warmed by condensing refrigerant
Sealed tube,tilted filled with refrigerant
Liquid refrigerant is evaporated by the
warm air
Condensed liquid flows back to warm side
Vaporous refrigerant is condensed by the cold air

• 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
