Carolina Heat Pipe, Inc.

Sensible Thermosyphon

A Heat Pipe Thermosyphon is an efficient device used to transfer heat from a warm point to a cooler point. All that is needed is the force of gravity and the fact that a fluid evaporates when it absorbs heat and releases heat when it condenses. Liquid refrigerant in the pre-cool section absorbs heat, evaporates and the vapor flows to the re-heat section where it condenses and releases heat. The condensed refrigerant flows back to the pre-cool section by the force of gravity to begin the cycle again. The Heat Pipe Thermosyphon process is a passive process that does not require a pump or compressor and does not consume any energy.

Controllable Subcool & Hot Gas Waste Re-heat

This system is intended primarily for direct expansion systems. It features Humidity Control, Total Part Load Performance, Energy Efficiency, Controllable Hot Gas Reheat, Passive Reheat, Subcool Reheat Option, and is Neutral BTU Ventilation capable.

Split System TRAHP™ Heat Pipes for Customized Energy Recovery

Carolina Heat Pipe Patented Split System TRAHP™ (Thermosyphon Run Around Heat Pipe) heat transfer concept brings a new capability to the use of Heat Pipe Science for Energy Recovery. By consolidating the performance of multiple heat pipes with interconnecting run around headers, Carolina Heat Pipe Inc. can transfer heat without location restrictions imposed by conventional heat pipe systems. This TRAHP™ development allows us to provide SPLIT SYSTEM HEAT PIPES for incorporating heating, ventilating and air conditioning systems. Now a system designer can stretch the heat pipe transfer surfaces, turn heat pipe surfaces, or separate these heat transfer surfaces several feet to strategically place them where wanted. This new development ELIMINATES earlier conventional heat pipe placement restrictions for multiple bent heat pipes or side-by-side air duct locations. Also because split system TRAHP™ heat transfer surfaces are separated by refrigerant charged headers, the heat transfer process can be controlled with an on-off signal or a modulating signal from a modern control system.
