An attractive way to directly exploit low temperature geothermal energy is to produce refrigeration using heat-driven absorption coolers. In Mexico this would contribute to the cold chain in areas of agricultural production and transshipment. An experimental 10.5 kW cooling capacity ammonia/water absorption cooler, that had been evaluated in the Cerro Prieto geothermal field, was modified to use ammonia/lithium nitrate (NH3/LiNO3). This prototype was successfully operated with generator temperatures from 90 to 145-degrees-C and with cold chamber temperatures from 0 to -10-degrees-C.
