Experimental comparison and analysis on silica gel and polymer coated fin-tube heat exchangers

Preparation and performance of desiccant coating with modified ion exchange resin on finned tube heat exchanger

“…It could be seen from cross section SEM image of non-modifying resin that IER desiccant coating through electrostatic spraying tightly bonded to aluminum foil surface and had no apparent cracks. Its thickness could arrive to about 120 μm, and the weight of desiccant coating was equivalent to that of aluminum foil , which was much greater than that reported in paper [22].…”

“…In addition, Ge [21,22] investigated a renewable desiccant heat exchanger which can accurately control the temperature of regeneration water, and established a mathematical model for desiccant heat exchanger . The experimental results are consistent with numerical analysis.…”

Experimental study on heat and mass transfer characteristics for a desiccant-coated fin-tube heat exchanger

“…It was concluded that the effectiveness of DCHE dehumidification far exceeded that of a conventional desiccant wheel system. Experiments were performed to compare two kinds of DCHEs coated with silica gel and polymer materials respectively [14], the results of which showed that the silica gel-coated heat exchanger had a higher average moisture removal, longer effective dehumidification time and superior thermal performance. A dynamic one-dimensional mathematical model was established to predict the performance of the silica gel-coated fin-tube heat exchanger cooling system driven by hot water at 50-70°C or solar energy [15,16].…”

An analytical prediction for performance and optimization of an annular fin assembly of trapezoidal profile under dehumidifying conditions

“…From their analysis, it was found that the values of Colburn and friction factors decrease with an increase in the tube row numbers. Ge et al [18] determined the performance of a desiccant-coated fin-tube heat exchanger under both the sensible heat and latent heat of the process of air. For energy efficient solutions, an investigation on the thermal performance of air-to-air heat exchangers with finned evaporator and condenser section was carried out by Jouhara and Meskimmon [19].…”
