  • Basics of the 4 Pipe HVAC System | Hunker

    The four-pipe HVAC system has a number of advantages over a two-pipe system. Four-pipe systems have separate heating and cooling fan coil units and separate pipes for heating and cooling. This means that hot or chilled water is always available, so the system can immediately change over from heating to cooling mode.

  • Heat Pipes, Solar Heat Pipe - Apricus Solar Water Heater

    The job of the heat pipes in the evacuated tubes is to rapidly transfer away the heat. The heat pipe capacity must therefore be greater than the evacuated tube's maximum output to avoid a bottle neck in the heat transfer chain. Apricus heat pipes have an average heat transfer capacity of >110Watts.
