HYBRID ABSORBING TYPE ELECTRICAL POWER AND COLD HEAT OR HOT HEAT SUPPLYING DEVICE

摘要

PROBLEM TO BE SOLVED: To promote a substantial energy saving in a system for generating electrical power and cold heat as well as hot heat. SOLUTION: A power generator 6 is driven by a micro-gas turbine 1 to generate electrical energy and an absorbing type cold water or hot water producing machine 10 is driven with discharged gas from a gas turbine 2 being applied as a heat source so as to generate cold heat or hot heat. The absorbing type cold water or hot water producing machine 10 may generate refrigerant vapor and condense absorbing liquid by a high pressure regenerator 11 and a low pressure regenerator 12. The refrigerant vapor generated from the low pressure regenerator 12 is compressed by the refrigerant compressor 8 and utilized as a heating source of the high pressure regenerator 11. The refrigerant compressor 8 is connected to an output shaft 4 of the gas turbine 2 via a clutch 9 to compress refrigerant vapor of relative low pressure under its high speed rotation, resulting in that its size can be set small. Since the low pressure regenerator 12 can decrease vapor pressure of the refrigerant vapor, it is possible to reduce evaporating temperature and further it is also possible to utilize solar heated hot water flowed from a solar panel 22 effectively as the heating source and improve a total coefficient of performance.
