Split Passive HRM-V™ Energy Recovery Heat Pipes Features
Passive Operation
No energy input is required to operate the heat pipes. When two air streams pass through the heat pipe, with one air stream through one coil and the other air stream through the other coil, the temperature difference between the two air streams activates the heat pipes and causes them to exchange heat. Heat pipe operation utilizes the heat capacity available when the working fluid changes phase, from a liquid to a vapor and back again. Because heat pipes use a phase change fluid, more heat transfer is achievable than with convection flow.
Long Life
There is nothing in the heat pipes to break or fail! They provide passive heat recovery where the only moving parts are the working fluid inside the tubes and the air to be treated. To guard against corrosion, the heat pipes can be ordered with a protective coating.
No Cross Contamination
Spilt passive energy recovery heat pipes are suitable for all applications, especially those where cross contamination is not acceptable. Airstreams can be located remotely with a horizontal and/or vertical separation to completely isolate hazardous exhaust from fresh intake air. Heat Pipe Technology also offers coatings and special materials of construction to protect coils from contaminated exhaust airstreams.
Minimal Maintenance
Since the heat pipes have no moving parts (except for optional dampers or control valves) no complex maintenance is needed. A periodic cleaning is the only required maintenance. A coil cleaner may be applied for this purpose just as for any cooling coil.
Design Flexibility
Split passive energy recovery heat pipes are custom designed for your particular application. Heat Pipe Technology’s manufacturing processes offer variations in materials of construction, fin density, circuiting, working fluids, and configurations. And since split passive heat pipe systems are suitable for remote supply and exhaust airstreams, they provide more design flexibility for applications where large ductwork cannot be positioned side-by-side.
