Abstract

A hybrid double absorption air cooling system employing a liquid desiccant solution and capable of operating at low heat source temperature between 55.degree. C. and 80.degree. C. is provided. In one embodiment the system which utilizes low-grade thermal energy, includes an open absorber employing a liquid desiccant solution for absorbing moisture from air passing therethrough, a cooling coil adapted for cooling air passing through the open absorber, and a vapor-absorption refrigeration system which employs the liquid desiccant solution as an evaporable refrigerant and is adapted for cooling and circulating a working fluid, such as water, through the cooling coil and for circulating the desiccant solution through the open absorber. In an alternate embodiment, an open evaporator is adapted for providing cooling water to the open absorber.
