FIELD: engines and pumps. ^ SUBSTANCE: air supply device (10) includes heat exchanger (11) by means of which circulation air flow (L2) supplied from the room can be cooled or heated. Air supply device (10) also includes mixing chamber (12) into which nozzles (16a1, 16a2Ç16an) are opened or gap (16) for flow for supply of primary (L1) air flow to mixing chamber (12) by means of which primary (L1) air flow leaving nozzles (16a1, 16a2Ç16an) or passing via gap (16) for flow in the form of flow (Qs) induces circulation (L2) air flow from the room (H), passing through heat exchanger (11) to mixing chamber (12). Combined (L1 + L2) air flow is supplied to the room (H). Air supply device (10) also includes control (100) bypassing on bypass way nozzles (16a1, 16a2Ç 16an) or gap (16) for flow for control of air flow (Q3) passing through control (100), by means of which, depending on use of the room, total (Q) air flow of fresh primary air (Q3 + Qs) supplied from outside of air supply device can be controlled. ^ EFFECT: enlarging the range of air flow velocities. ^ 11 cl, 13 dwg |
