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

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].…”

Performance evaluation and simulation of a new absorbent for an absorption refrigeration system

“…The drawbacks of many working fluids, such as lithium bromide Potassium formate is cited in literature [5] because of its physical properties and absorption-desorption rates, which make it suitable for its use in an absorption cycle. Potassium formate shows lower crystallization temperature, density and viscosity lower than lithium bromide, smaller vapour pressures, alkaline pH, less toxicity and is biodegradable [6]. The latent heat of absorption of potassium formate is lower than the lithium bromide and it has a good compatibility with other compounds or additives.…”

“…Lowpressure refrigerant vapour (2) from the evapourator is absorbed by the strong solution (8) coming from the generator. The pump receives low-pressure liquid weak solution (3) from the absorber, elevates the pressure of the weak solution (4), and delivers it to the generator (6). In the generator, heat from a high-temperature source (15) drives off the refrigerant vapour in the weak solution.…”

Vapour pressures, densities, and viscosities of the (water+lithium bromide+potassium acetate) system and (water+lithium bromide+sodium lactate) system

“…With the employment of this proportion, these systems possess properties similar to lithium bromide, namely the relation of solubility to vapour pressure, the absorbance of water vapour, and the added advantage of the other salts that lead to significant decrease of the temperature of the generator [15]. Three basic physical properties (vapour pressure, density, and viscosity) were measured over extensive temperature and concentration ranges.…”
