Abstract

In hot and moist weather, a hybrid liquid desiccant dehumidification conditioning (LDAC) system is proposed as a viable substitute to stand-alone conventional vapour compression refrigeration (VCR) system because of their dominance in extracting the latent heat load from the air, being environmentally friendly, removing pollutants from the processed air, and consuming less electrical energy. The current research article experimentally investigates the dehumidification performance of a potassium formate (KCOOH) solution on an innovatively designed and developed 5-kW hybrid LDAC system. The main aim of this research paper is to optimize the performance parameters of a hybrid LDAC system employing a full factorial DOE design. The three input variables are selected to evaluate their effects on the three output performance responses. The regression correlation is obtained to anticipate the performance of the KCOOH solution for the output responses. The experimental result reveals that their improvement of 26.97% in \({\mathrm{COP}}_{{{\mathrm{Hybrid}}}}\) as compared to a stand-alone VCR unit and that the influence of inlet desiccant concentration is more prominent than the inlet mass flow rate and inlet desiccant temperature on the output responses.
