Title:
HEAT STORAGE TYPE TEMPERATURE DIFFERENCE STORAGE BATTERY, COMBINED HEAT AND POWER SYSTEM, AND COMBINED HEAT AND POWER SYSTEM GROUP
Document Type and Number:
Japanese Patent JP2022064235
Kind Code:
A
Abstract:
To provide a heat storage type temperature difference storage battery, which is a novel type battery that generates electricity by using heat media having different temperatures stored in a heat pump cycle.SOLUTION: A heat storage type temperature difference storage battery includes a compressor for compressing a heat medium, a first flow path connected to the compressor, an accumulation heat insulation high temperature storage tank connected to the first flow path, a second flow path connected to the accumulation heat insulation high temperature storage tank, an expansion device provided in the second flow path and configured to reduce the pressure of the heat medium flowing through the second flow path, an accumulation heat insulation low temperature storage tank provided on the upstream side or the downstream side of the expansion device in the second flow path for storing the heat medium of the second flow path, a third flow path connected to the downstream side of the second flow path and configured to supply a heat medium through each of the expansion device and the accumulation high insulation low temperature storage tank to the compressor, and a temperature difference generator configured to generate electricity by using the temperature difference between the heat medium flowing on the upstream side of an expansion turbine in the second flow path and the heat medium flowing through the third flow path.SELECTED DRAWING: Figure 1
