In this paper, the generation of low-temperature heat for cooling and refrigeration by a chemical heat pump using CaO/H2O/Ca (OH) 2 reaction is proposed. The temperature level of the heat and the heat-generation rate were investigated experimentally.
It was found that low-temperature level heat around 273K was generated by use of the proposed chemical heat pump unit. The heat-generation was improved by heat and mass transfer augmentation in the reactant bed, and the temperature level of the heat was lowered. It was also recognized that the evaporation and mass transfer at low pressure should be enhanced in order to improve the heat-generation.
