• Wrap around heat pipe are bult with aluminum-finned tubes and are charged with R134a refrigerant. They have no moving parts.
  • THE DX COIL IS WRAPPED BY THE HEAT PIPEWhen the DX coil start removing heat from the air-flow, the heat pipe wicking mechanism starts.  As the downstream portion is cooled, the upstream portion captures heat from the incoming air-flow.  The heat travels from the upstream to downstream sections proving free pre-cool and post-reheat.

  • This unit was designed to introduce 8000 CFM of FA and exhaust 7000 CFM while providing heating, cooling, energy recovery and dehumidification using a wrap around heat pipe
  • Cooling is provided by an external condensing unit with 3 stages of capacity equipped with a hot gas by-pass valve on the first stage
  • First stage of energy recovery is done by an enthalpy wheel that recovers latent and sensible energy, transferred to and from the incoming and outgoing airflows
  • Second stage of energy recovery was by means of a heat pipes wrapped around the DX cooling coil. This provided a saving of 56MBH (4.7T) on the FA pre-cooling and it provided 56MBH of reheat
