Title:
TEMPERATURE ADJUSTMENT IN A HEAT REGENERATOR USED IN EQUIPMENT FOR STORING ENERGY BY ADIABATIC AIR COMPRESSION
Document Type and Number:
WIPO Patent Application WO/2010/146292
Kind Code:
A3
Abstract:
The invention relates to a method for adjusting the temperature of a heat regenerator (ST1, ST2) used in equipment (10) for storing energy by adiabatic air compression. The regenerator is subjected to a series of operation cycles, each cycle including a compression phase followed by an expansion phase. Between two consecutive cycles, the method consists of cooling a lower compartment (26a) of the layer of refractory material (26) of the regenerator, which is located in the vicinity of a lower distribution box (24), down to a temperature that is compatible with the required temperature range of the air exiting the heat regenerator during the compression phases. The invention also relates to such a heat regenerator.
