We have choices in equipment that we can select for air to air energy recovery applications, we even have the best options for Geothermal Heating and Air systems. Here are 5 advantages that Heat Pipes offer;
Energy Recovery Heat Pipes Features
1. Passive Operation
No energy input is required to operate the Heat Pipes. There are no moving parts. When two air streams pass through the Heat Pipes, one air stream on the supply side and the other on exhaust side, the temperature difference between the two air streams heats and cools refrigerant. The phase change of the refrigerant, from a liquid to a vapor and back again, transfers energy from one side to the other. It’s simple.
2. Long Life
There is nothing in the Heat Pipes to wear out! The Heat Pipes are passive. They have no moving parts. To guard against corrosion, the Heat Pipes can be ordered with a protective coating. The Heat Pipes are fabricated with a multitude of charged circuits. Under normal operations, there is no reason for these ever to leak. If one of the many circuits did leak there would be little impact on performance as other circuits would still function.
3. Isolated Air Streams
Dividing partitions to separate the two air streams can be easily added to Heat Recovery Heat Pipes. The copper tubes carrying the Heat Pipe working fluid are expanded into the mating holes in the dividing plates assuring an excellent seal to prevent cross contamination. This divider makes heat pipes a good choice in laboratory type applications, where cross contamination is a concern.
4. Minimum Maintenance
Since the Heat Pipes have no moving parts, the only maintenance recommended is periodic cleaning. A coil cleaner may be applied for this purpose just as for any cooling coil.
5. Flexible Size
Heat Recovery Heat Pipes from can take up less space than other heat recovery schemes. They can also be manufactured in custom sizes to fit nearly any application. Heat pipes can also be compact in depth. A six-row heat recovery heat pipe can be fabricated with a thickness of as little as 8 inches.
