Experimental investigation of the solid desiccant dehumidification system with metal organic frameworks

•This paper investigate the dehumidification performance of MOFs desiccant coated heat exchanger.•Maximum water uptake capacity of MOFs desiccant was around 0.4 g•g−1 in given operating condition.•90% of MOFs with 10% of solvent and binder mixture coated on the metallic fin of heat exchanger.•Increase of coating thickness can achieve the 131% of dehumidification performance.•The decrease of space velocity shows the over 160% enhancement of dehumidification performance.
