Field tests of a residential liquid-desiccant dehumidifier are described. From analysis done in Phase I of this program, a gas-fired boiler for regenerating the desiccant was selected with a one-ton capacity dehumidifier. Three field-experiment units were built. One was installed at a test house in Gaithersburg, Maryland owned by GEOMET Technologies. The second was installed in Atlanta, Georgia, supported by the Atlanta Gas Light Company. The third unit was shipped to Lone Star Gas Company, Forth Worth, Texas, to be installed in 1989. Once startup problems were corrected, the units ran reliably, controlling indoor humidity accurately. The seasonal COP for the Gaithersburg installation was 0.58; for Atlanta the COP was 0.50. By extending the operating periods (typically 5 minutes in these tests), the COP should increase. A manufacturing cost study of the residential dehumidifier showed that a factory cost of $553.62/unit is achieved at 50,000 units/year volume.
