Title:
HEAT ACCUMULATING FACILITY WITH PUMPING-UP POWER GENERATION
Document Type and Number:
Japanese Patent JP3289151
Kind Code:
B2
Abstract:
PURPOSE: To improve efficiency of facilities and operation and to drastically reduce construction cost compared with separate construction of underground pumping-up power generation facilities and underground heat accumulating facilities for heat source for local heating and cooling by accumulating heat of a heat source for local heating and cooling utilizing a reservoir for pumping-up power generation.
CONSTITUTION: An upper reservoir 2 is connected to a lower reservoir 3 through a storage pipe 4 and a flow pipe 5, and water reserved in the lower reservoir 3 is pumped up to the upper reservoir 2 through the storage pipe 4 by a storage pump 6 operated utilizing surplus power. In pumping-up power generation in which the pumped-up water from the upper reservoir flows to the lower reservoir 3 through the flow pipe 5 at the time of concentrated power consumption to generate power, the water reserved in the upper reservoir 2 is cooled or heated by a heat exchanger 8 arranged at the storage pipe 4 to accumulate quantity of heat, and this accumulated heat is taken out by a heat exchanger 12 arranged at the flow pipe 5 to be utilized for local cooling and heating, etc., in this heat accumulating facilities with pumping-up power generation.
