摘要： PROBLEM TO BE SOLVED: To provide a mixed medium power generation system reduced in construction cost by reducing the size of a condenser for condensing exhaust of a mixed medium turbine. SOLUTION: This mixed medium power generation system uses a mixing and absorbing means for feeding exhaust from the mixed medium turbine to a sucking part, feeding mixed medium liquid separated from the mixed medium steam to a driving nozzle, and jetting the mixed medium liquid from the driving nozzle into a main body nozzle at high speed to such the exhaust into the main body nozzle so that the exhaust is mixed with the mixed medium liquid and absorbed therein. Thus, the mixing medium can flow into condenser means, whereby the heat exchange efficiency at a heat exchange art of the condenser means can be heightened, and the means is made compact so as to reduce the construction cost.

摘要： PROBLEM TO BE SOLVED: To improve an output speed of cold heat from an ice heat accumulation tank by providing at least a single concentration water injection means to inject return water against the given local region of an ice heat accumulation tank. SOLUTION: A concentration water injection nozzle 12 serving as at least a concentration water injection means to inject return water 10 against the given local region of an ice heat accumulation tank 1 is disposed at the upper part of the ice heat accumulation tank 1 and water injection is controlled by a water injection control means. The heated return water 10 from a heat load 9 is concentratedly returned to a limited water area in the ice heat accumulation tank 1 by the concentrated water injection nozzle 12. As a result, a high water flow is generated in the vicinity of the water injection point of the return water 10 in an ice heat accumulation tank 1 and injected return water 10 is well mixed with peripheral water 2. Thus, since heat-exchange between ice 4 and water 2 is promoted through agitation operation, the feed of a cold heat to the heat load 9 is effectively executed.
