Résumé

An absorption heat-pump system which recovers heat efficiently from a low temperature heat source such as river water is a combination of two cycles using different working fluids. This absorption heat pump system called a dual loop cycle is able to recover heat from low temperature level heat sources such as water up to 5°C. In the paper, dual cycle optimization and selection of new working fluids are discussed. The combination of TFE/NMP working fluids for low temperature range and water/lithium bromide for a high temperature range result in a high COP that is 1.3 in cooling and 1.4 in heating. Technology which has been developed in this research will be applied for district heating/cooling, air conditioning and cold storage/refrigerated warehouse systems.
