In the heat utilization installation (1) according to the invention several heat sources (2) are included which are provided each with a jet pump (16), (17), (18), (19). The heat sources (2) are connected to a heat carrier circuit system (7) which includes a single, central circulating pump or circulating pump unit (20). The individual jet pumps (16) to (19) are so controlled for the respective heat sources (2), the required operating temperatures with respect to temperature difference between the outlet and inlet and the flow volume are maintained or achieved. With the possibility of independent control of the flow volumes at the various heat sources (2), uniform fluid temperatures as required for a buffer store (22) or heat consumers can be maintained. |
