Abstract: ABSTRACT          A cooling process and apparatus which utilizes the lower water vapor pressure above a fluid such as water-salt solutions of, for example, calcium chloride, lithium chloride,  lithium bromide or mixtures thereof.  Heat is then removed from the fluid by indirect contact with a circulating water stream in a heat exchanger.  Water which has taken up heat from the fluid is expanded at reduced pressure to release water vapor and lower the temperature of the water.  The water vapor is then absorbed in a salt solution having a higher temperature but a lower water vapor pressure than that of the released water vapor.  The remaining water is recirculated to the heat exchanger.
