Experimental analysis of the absorption and desorption rates of HCOOK/H2O and LiBr/H2O

Comparative review of membrane-based desalination technologies for energy-efficient regeneration in liquid desiccant air conditioning of greenhouses

“…New desiccants have low crystallization temperature, low density, high solubility and are less corrosive, toxic and volatile [47,49] and more environmentally safe [49] compared to conventional desiccant solutions. HCO2K is preferred due to additional benefits, such as lower manufacturing cost and higher vapour pressure, which can reduce the energy requirements of the regeneration process [70]. Nonetheless, high vapour pressure negatively affects the dehumidification process, which requires low vapour pressure to operate efficiently.…”

Long-term solar heat storage process by absorption with the KCOOH/H2O couple: Experimental investigation

“…The H2O/KCOOH solution is environmentally friendly, nontoxic and nonflammable; has an advantageous theoretical heat storage energy density; and costs less than half the price of the couples usually used in absorption processes (LiBr/H2O or LiCl/H2O) (Lefebvre, 2015). Its aqueous solution is also weakly alkaline and therefore noncorrosive and biodegradable (Longo and Gasparella, 2016), and has a lower density and viscosity than absorbents such as lithium bromide (Riffat et al, 1998). These advantages together with its relatively low cost make it a prime choice as the absorbent for the heat storage process.…”

Experimental investigation of a building integrated photovoltaic/thermal roof collector combined with a liquid desiccant enhanced indirect evaporative cooling system

“…Then, the regenerated desiccant solution is sent back to the desiccant core for better dehumidification performance. In this experimental study, environmentally friendly, relatively less corrosive, lower cost, lower density and viscosity potassium formate (HCOOK) solution was utilized as a liquid desiccant [25].…”
