A vapor compression refrigeration cycle device includes a main refrigerant circuit formed by sequentially connecting a compressor, a use-side heat exchanger, an intermediate heat exchanger, a first expansion device, and a heat source-side heat exchanger to one another through a refrigerant pipe; a bypass refrigerant circuit which branches off from the refrigerant pipe located between the use-side heat exchanger and the first expansion device, and which is formed by sequentially connecting a second expansion device, the intermediate heat exchanger, and a compression midstream of the compressor; and a controller. When a pressure ratio of discharge pressure of refrigerant discharged from the compressor and suction pressure of refrigerant sucked into the compressor is equal to or smaller than a reference pressure ratio, the controller is configured to control the compressor such that the number of rotations of the compressor is increased.

A post-control electric power amount curve generating portion generates plural pieces of running control information indicating a changeable running method for each device and plural post-control electric power amount curves indicating an amount of main electric power. A post-control hot water storage amount curve generating portion generates post-control hot water storage amount curves each indicating an accumulated amount of hot water generated in a case where the fuel cell generates electric power based on the plural post-control electric power amount curves. A hot water storage completion determining portion determines whether the accumulated amounts exceed a specific heat capacity. A reduction amount calculating portion calculates plural energy cost reduction amounts produced before and after the change using the post-control hot water storage amount curves determined as not exceeding the specific heat capacity. A running method determining portion determines the running control information corresponding to the largest energy cost reduction amount.

A fuel-cell power generation system includes a fuel-cell power generator, a power measurement section for measuring an actual power-consumption value in a household appliance, and a power-consumption estimation section for estimating a future power-consumption value over a given time-period after a given time point, in accordance with the actual power-consumption value measured by the power measurement section. Moreover, the system includes a power-generation instruction section for determining the need of startup/stop of the fuel-cell power generator in accordance with the estimated power-consumption value from the power-consumption estimation section.

An operating condition determiner compares an operation starting time (t) of network-connected first consuming apparatuses received by a schedule information receiver and a consumption starting time (t) predicted by a predicting system based on a total consumption amount of the first consuming apparatuses and a second consuming apparatus, which is not network-connected, and determines the operation starting time (t) as an operation starting time of a fuel cell if the operation starting time (t) is earlier than the consumption starting time (t) while determining the consumption starting time (t) as such if the operation starting time (t) is later than the consumption starting time (t), so that the fuel cell can stably generate power. The fuel cell can stably supply power at a time when the consuming apparatuses start consuming power. The merit of introducing a cogeneration facility can be sufficiently exhibited even if both consuming apparatuses provided with a network connecting function and those provided with no such function exist.
