Create More Energy Savings with Passive Dehumidification

Published on: April 25, 2012

A new technology has been developed that will allow both business and homeowners to save on air conditioning and heating bills. Passive dehumidification through heat pipe technology removes more humidity than other systems. Best of all, it uses no extra energy in the process. Traditional systems use energy for the heating, cooling and dehumidification processes.


In heat pipe technology, the system is divided into two main sections. These sections are called the pre- cool pipes and the reheat pipes.

It is important to understand a couple of processes. The first is the movement of heat. Heat moves to the cooler area in basic physics. The second process is condensation. When the ambient air is warmer outside a pipe filled with cold fluid, condensation forms from the air.

In the pre- cool section, the air drawn in through the filter in the air conditioning and heating system is sent over the heat pipe filled with refrigerant. The fluid absorbs heat, and carries it to the second set of pipes. The air is then sent to the coils in the system. The coil is the place in which the majority of cooling takes place through heat transfer.

Condensation occurs in the pre- cool section and in the coils. The removed condensation is sent outside through the drain. The air has not finished its trek through the air conditioning and heating system yet. The air has been cooled by both the pre- cool pipes and further by the coils. It needs to be reheated before it returns to the inside at a comfortable temperature.

From the coils, the air is sent to the reheat pipes. The heat removed from the pre- cool section is then used to warm the super- cooled air. More condensation forms; further dehumidifying the air than a conventional air conditioning and heating system.

All air conditioning systems have a finite working life. During an upgrade to a more energy efficient system, passive dehumidification through heat pipe transfer could provide you with significant energy savings.
