STUDY ON GEOTHERMAL REFRIGARATION

Abstract

Geothermal heat can be used for different purposes, depending the operating temperature of thesource. Usually, incase of low and medium-enthalpy sources, geothermal energy is used directly, for space heating, domestic hot water, agricultural uses, etc. Conversely, in case of high-enthalpy geothermal resources, heat is more profitably converted in to electricity or in more complex cascade cycles. Low or medium temperature geothermal energy can be converted in to electric power only when innovative and expensive system layouts areconsidered. Unfortunately, at are as on able depth only low-enthalpy geothermal energy is usually available; only in some specific locations in the world, high-enthalpy geothermal resources are available even using low-depth wells
