1. A ventilation device with a through housing (1) that is a duct for an air jet flow, wherein
the through housing (1) is connected to an opening (10) of a building partition (9), with a stationary regenerative heat exchanger (5) and a pumping section (4) formed of a centrifugal fan (41) of constant rotation direction and a main reversible air jet driver (42) with an individual drive (43) arranged in series inside the housing (1), characterized in that the heat exchanger (5) is provided with a metallic pressure vessel (PV) with at least one heat exchange system (51) attached to walls (53) of the pressure vessel (PV), wherein
an interior (531) of the pressure vessel (PV) is filled with a thermodynamic working agent (WA) and connected to a cyclic discrete pressure control system (7) of the working agent (WA), wherein
the cyclic discrete pressure control system (7) of the working agent (WA) is provided with a vapour compressing device (72) having an outlet port (721) connected with a high pressure buffer vessel (73) and a high pressure sensor (731), wherein
an inlet port (722) has connection with a low pressure buffer vessel (74) and a low pressure sensor (741), wherein
the cyclic discrete pressure control system is further equipped with a three-position two-way valve (75), included in the working agent (WA) circuit, and wherein
the vapour compressing device (72) is a compressor (78) or a household device (8) provided with the compressor (78) of the working agent (WA) that is connected to the high pressure buffer vessel (73) through a high pressure conduit (76) and to the low pressure buffer vessel (74) through a low pressure conduit (77).
