1. Installation for the transport of heat by means of a fluid with at least one heat source (1), which is connected through ducts (3, 7, 11, 13) with at least one heat sink (9), a valve (17) interposed in the ducts (11, 13) for the setting of the heat to be transported, two temperature sensors (15, 21), of which one is interposed in a duct (3, 11) conducting the fluid to the heat sink (9) and one is interposed in a duct (13) conducting the fluid away from the heat sink (9), a throughflow-meter (23) interposed in one of these ducts, and measuring and control means (31, 33), which are connected with the temperature sensors (15, 21), the throughflow-meter (23) and the valve (17), to determine the transported heat from the measured temperatures and throughflows and to interrupt the heat flow (s) from the heat source (1) to the heat sink (9) when the throughflow (q) measured by the throughflow-meter (23) falls to a lower limit value (qmin ) in an operational state, characterized in that the named valve (17) serves on the one hand for the continuous variation of the heat flow (s) and on the other hand for the interruption of the heat flow (s) when the named operational state occurs, and that the measuring and control means (31, 33) are constructed to define a target value for the named heat flow (s) as well as to determine the actual value of the heat flow (s) from the measurement values of both the temperature sensors (15, 21) and the throughflow-meter (23) and to regulate it by means of the valve (17). |
