“…In general, equations of vapor-liquid equilibrium describe the principle of chemical absorption and investigate the effects on gas solubility caused by temperature and pressure [20][21][22]. In specific for CO 2 absorption, the main task of such models is to determine the partial pressure of CO 2 over an aqueous solution of alkalonamine (or other solvent) and also quantify the energy required for regeneration.…”

“…This was said to be a result of the exit humidity ratio and air temperature being lower in the parallel flow arrangement than in the counter flow. However, elsewhere [64], counter flow arrangement has been shown to provide better performance.…”

Liquid desiccant cooling systems (LDCS) are energy efficient means of providing cooling, especially when powered by low-grade thermal sources. In this paper, the underlying principles of operation of desiccant cooling systems are examined, and the main components (dehumidifier, evaporative cooler and regenerator) of the LDCS are reviewed. The evaporative cooler can take the form of direct, indirect or semi-indirect. Relative to the direct type, the indirect type is generally less effective. Nonetheless, a certain variant of the indirect type -namely dew-point evaporative cooler -is found to be the most effective amongst all. The dehumidifier and the regenerator can be of the same type of equipment: packed tower and falling film are popular choices, especially when fitted with an internal heat exchanger. The energy requirement of the regenerator can be supplied from solar thermal collectors, of which a solar pond is an interesting option especially when a large scale or storage capability is desired.
