Summary

TWO SYSTEMS ARE EXAMINED FOR GETTING REFRIGERATION FROM GAS COMBUSTION: CONVENTIONAL REFRIGERATION CYCLES DRIVEN BY THERMAL ENGINES OR STEAM TURBINES AND AIR DEHUMIDIFYING BY MEANS OF HYGROSCOPIC MATERIAL THAT IS REGENERATED BY HEATING. CENTRIFUGAL COMPRESSORS CAN BE COUPLED WITH STEAM OR GAS TURBINES, WHEREAS RECIPROCATING OR ROTATIVE COMPRESSORS ARE MORE SUITABLE FOR CONVENTIONAL INTERNAL COMBUSTION ENGINS ESPECIALLY IN THE CASE OF GAS TURBINE CYCLE, THE THERMAL EFFICIENCY OF WHICH IS RATHER LOW, IT IS ESSENTIAL TO RECOVER HEAT FROM THE EXHAUST GAS. AIR DEHUMIDIFYING BY MEANS OF ABSORPTION IS SEEN AS AN ALTERNATIVE TO THE CONVENTIONAL METHOD BASED ON REFRIGERATION. SUCH A TECHNIQUE COULD BE PROFITABLE, IN THE PRESENCE OF A LARGE AVAILABILITY OF CHEAP THERMAL ENERGY, PARTICULARLY WHEN THE LATENT HEAT LOAD IS HIGH, OR WHEN AN EXTREMELY LOW AIR HUMIDITY IS REQUIRED.
