N/A The new working fluid was selected the water-lithium bromide-lithium nitrate-lithium chloride-Ethanol amine System. mole ratio of LiBr-LiNO₃-LiCl is 5 : 1 : 2. And surfactant as like Ethanol amine was added 5wt% of total amount. The solubility data were obtained in the temperature range 253.15K∼363.15K. The vapor pressure data were correlated as an Antoine-type equation. Duhring charts were constructed through the measurements of solubility and vapor pressure. Thus the operation range of this system were found to be broadened. Heat Capacity of water-lithium bromide-lithium nitrate-lithium chloride-Ethanol amine System is higher than one of lithium bromide system. And COP were obtained at various generator temperature. Finally, COP of water-lithium bromide-lithium nitrate-lithium chloride-Ethanol amine System is higher than one of LiBr system at Te=5℃, Ta=Tc=45℃ and Te=7℃, Ta=Tc=45.

The new working fluids were composed of three salts such as lithium bromide, lithium nitrate and lithium chloride and added two organic surfactants (ethylene glycol, ethanol amine) of 1∼5wt%, respectively. The solubility data were obtained in the temperature range 253.15∼363.15K. The vapor pressure data were correlated as an Antonie`s equation. The properties of working fluids were investigated as functions of surfactant contents. As the surfactant contents were increased, the crystallization temperature of working fluids was determined to decrease. However the vapor pressure was increased with surfactant contents slightly.
