Research Progress of Liquid Desiccant Evaporative Cooling Air Conditioning System

Evaporative cooling technology is a refrigeration technology by water evaporating endothermic, with zero-pollution, environmental-friendly, energy saving, and other advantages, which makes it widely used. Nevertheless, due to its working characteristic, the application of evaporative cooling technology is limited, particularly in some areas with high humidity. Using the liquid desiccant dehumidification and evaporative cooling technology leads to a solution, named liquid desiccant evaporative cooling air conditioning system extends the application of evaporative cooling technology. This article on liquid desiccant evaporative cooling system provides a brief overview about research status, full usage of the low grade thermal energy, the practical application and new development of the system.
