    Abstract

    The great need for cooling combined with Mexico's large availability of low enthalpy geothermal energy, makes it very attractive to utilize this resource for cooling using heat driven absorption systems. Mexico posseses large amounts of brine at temperatures which are too low to enable electricity to be generated efficiently and economically. Of the possible non electric uses of low and medium enthalpy geothermal energy are, to provide cold storage facilities for perishable foods and produce ice using the heat driven absorption cooling systems. The main purpose of the work described in the thesis is to obtain experimental data on heat driven absorption cooling systems using geothermal energy for the design of large scale systems. An experimental study on the performance of the ammonia-water absorption cooler operating on low enthalpy geothermal energy at the Cerro Prieto Geothermal Field was made. The system was used to cool a small storage unit at below freezing temperatures, during 8 hour tests and 24 hour tests. An experimental study on the performance of the ammonia-water absorption cooler operating on low enthalpy geothermal energy at the Cerro Prieto Geothermal Field, has been made in order to operate it as an ice-making machine. Some prototypes of ice generators were designed, installed and operated. An experimental study of a fluidized bed heat exchanger prototype connected to the ammonia-water absorption cooler was made in order to use the geothermal brine at the Cerro Prieto Geothermal Field. Computer models based on LOTUS 123 worksheet were developed. These models were developed to calculate quickly and accurately the thermodynamic data from the water-ammonia absorption systems.
