Vertically-standing, insulated layer heat buffer storage i.e. pressure or pressureless container, for low-temperature energy collector in e.g. heat engine, has active cooler reducing temperature of fluid in storage below cooler temperature

摘要

The storage (1) has an integrated absorption-cooling system (3), and an active cooler (12) for reducing temperature of heat-carrying fluid in lower part of the storage below entry temperature of thermosolar and/or photovoltaic cooler (6), where heat stored in the storage provides process heat to a heat engine. A heat-insulated inner pipe (4) is designed as a standpipe and dimensioned such that cross-section of the inner pipe corresponds to an outer ring of an inner pipe. Inner areas of the inner pipe and the outer ring are filled with heat storage material.
