Energy Recovery Wheels | What is an Enthalpy Wheel?
14 views
Introduction:
Many buildings require substantial  amounts of outside air to be brought in through their ventilation systems. In many cases it is code ( schools) and in other cases it constitutes make up air for contaminated exhaust air (laboratories). Regardless, exhausting expensive conditioned indoor air and replacing it with outdoor air is really expensive. Energy recovery devises, like the Enthalpy Wheel, can be incorporated in the design to transfer outgoing temperature and humidity (energy) to the incoming outdoor air.

 A heat pipe is a thermal transfer device. It's basically a sealed tube filled with refrigerant. It typically spans the supply air and exhaust air sides of a system. Energy is transferred - with no moving parts - from one air stream to the other (as long as there is a temperature difference). Refrigerant is evaporated on the hot side and moves to the other end of the pipe because of vapor pressure. On the cold side refrigerant condenses and then flows back. It's really that simple.
