Method, heat accumulator and heat accumulator system for heating and cooling a working fluid

摘要

The invention relates to a method for heating and cooling a working fluid (2) using at least one thermochemical heat accumulator medium (3), wherein the working fluid (2) is guided through at least one thermochemical heat accumulator (6) comprising the heat accumulator medium (3), wherein the working fluid (2) is guided without contact to the heat accumulator medium (3), wherein upon charging of the heat accumulator medium (3) a heat flow (Q) is transferred from the working fluid (2) to the heat accumulator medium (3) and at least one substance (15) is released from the heat accumulator medium (3) and discharged from the heat accumulator (6), and wherein upon discharging of the heat accumulator medium (3) the substance (15) is fed with release of heat to the heat accumulator medium (3) or at least to a reaction product of the heat accumulator medium (3) that was produced during charging of the heat accumulator medium (3), and a heat flow (Q) is transferred to the working fluid (2).

1. A method for heating and cooling a working fluid using at least one thermochemical heat accumulator medium, wherein,
the working fluid is guided through at least one thermochemical heat accumulator comprising the heat accumulator medium, the working fluid being guided without contact to the heat accumulator medium, wherein upon charging of the heat accumulator medium a heat flow is transferred from the working fluid to the heat accumulator medium and at least one substance is released from the heat accumulator medium and conveyed away from the heat accumulator, and wherein upon discharging of the heat accumulator medium the substance is fed, releasing heat, to the heat accumulator medium or at least to a reaction product of the heat accumulator medium that was produced during charging of the heat accumulator medium, and a heat flow is transferred to the working fluid, wherein the charging of the heat accumulator medium is performed at a first pressure level by a compressor and the discharging of the heat accumulator medium is performed at a second pressure level by the compressor, the second pressure level being higher than the first pressure level, guiding an auxiliary fluid to the thermochemical heat accumulator medium, wherein flow direction of the auxiliary fluid during the switch between the charging of the heat accumulator medium and the discharging of the heat accumulator medium is inverted.
