Performance characteristics of a commercially available gas-fired desiccant system.

Author(s) : JALALZADEH-AZAR A. A., STEEL W. G., HODGE B. K.

Summary

The system under consideration utilizes a rotary desiccant wheel that is regenerated by a gas-fired hot water heating system. The constituents of the study are: 1) evaluation of the issues critical to accurate data acquisition and 2) examination of the sensitivities of system performance parameters to perturbations in certain design set points. The effectiveness of a mixing device in providing a uniform-property supply air is demonstrated. Two design variables, regeneration-to-process air ratio and regeneration temperature, are allowed to deviate from their respective set points, while the responses of the system performance parameters (an overall COP for dehumidification, a local COP, the moisture removal capacity, and the effective equivalent cooling capacity) are observed.
