The performance of a laboratory scale dehumidifier has been measured under controlled laboratory conditions, yielding a maximum dehumidifier specific moisture extraction rate (SMER_d) of 7·94 kg kW⁻¹ h⁻¹ at 50°C and 85% relative humidity. Although we are not aware of any published data on dehumidifier systems having higher SMER_d, there appears to be further scope for improvement, as the exergetic efficiency of the unit was in the region of only 4–12%. © 1997 by John Wiley & Sons, Ltd.
