One technology that addresses this problem is the dehumidifying heat pipe. It is a device that enables an air conditioner to dehumidify better and still efficiently cool the air. It does not need additional electricity to operate. The heat pipe is ideal for hot, humid environments. A dehumidifying heat pipe resembles two heat exchangers, located on either side of the air conditioner s evaporator coil.
Several tubes connect the two sections.
This causes the refrigerant in the tube to evaporate. After the refrigerant in the tubes changes into a vapor, it flows to the condensing section at the other end of the system. There, it releases its heat into the air stream and returns to its liquid state again. It then flows by gravity to the evaporator end of the pipe to begin the cycle again. The dehumidifying heat pipe is used mostly in commercial and industrial applications.
