Title: ARRANGEMENT, PARTICULARLY REFRIGERATING MACHINE OR HEAT PUMP
Abstract:
The invention relates to an arrangement (1) comprising: a first and second heat tank (2a, 2b); a thermochemical reactor (5) which is thermally and fluidically connected to the heat tank (2a, 2b); a heat transfer fluid circuit (3) containing a heat transfer fluid (F) for transporting heat between the two heat tanks (2a, 2b) and the thermochemical reactor (5); a temporary heat store (100) arranged in the heat transfer fluid circuit (3), for the temporary storage of the heat transfer fluid (F), the temporary heat store being designed to receive the heat transfer fluid (F) at two different temperature levels (T1, T2) and also comprising a first partial store (101a) with variable storage space (102a) and a second partial store (101b) with variable storage space (102b) which is thermally and fluidically separated from the first; and a valve system (9) provided in the heat transfer fluid circuit (3), which comprises at least one movable valve device (10a, 10b) by means of which the heat transport between the two heat tanks (2a, 2b), the thermochemical reactor (5) and the temporary heat store (100) can be controlled by means of the heat exchange fluid (F).
