Title: Dehumidifier
Inventor: HONDA SHIN
IPC: F24F3/14
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To recover a sufficient amount of heat from the air having heated adsorption mediums without increasing the size of a dehumidifier and manufacturing costs. SOLUTION: A heating medium composed principally of water is circulated through a first and second heat exchangers 130 and 140 to recover heat. Thus, since the heating medium composed principally of water having a larger heat transfer rate than air is heat exchanged with the air, the heat exchange efficiency is higher in comparison with the case in which air is heat exchanged with air, and hence a sufficient amount of heat (energy) can be recovered. As a result, a sufficient amount of heat can be recovered from the air having heated the heat medium, without increasing the size of the dehumidifier and manufacturing costs. Further, since the air supplied to the second heat exchanger 140 can be reliably cooled close to the air temperature in a space to be dehumidified, a large amount of condensed water can be generated.
