A cooling and/or heating device (10, 60) for use in the cooling and/or heating of one or more units (8a to 8c) includes a conduit network containing flow and return conduits (14, 16; 68, 70), with several circuits (12a to 12c; 32 to 38, 74 to 78) connected to the flow and return conduits (14, 16; 68
A cooling and/or heating device (10, 60) for use in the cooling and/or heating of one or more units (8a to 8c) includes a conduit network containing flow and return conduits (14, 16; 68, 70), with several circuits (12a to 12c; 32 to 38, 74 to 78) connected to the flow and return conduits (14, 16; 68, 70). Valves (28, 88, 96) are located in each circuit and used to regulate or control the volumetric flow through the circuits (12a to 12c; 32 to 38; 74 to 78). A heat transfer medium or coolant circulates through the conduit network, with at least one consuming device disposed in each circuit. Sensors (38) are provided in each circuit (12a-12c; 32-38; 74-78), the sensors (38) sending signals to a control unit and forming part of a control circuit. The control unit adjusts the valves (28, 88, 96) of each circuit as a function of the signals transmitted from the sensors (38) so as to hydraulically balance the individual circuits.

The invention claimed is: 1. A cooling and/or heating device (10, 60) comprising: one or more heating or cooling units (8a-8c),a conduit network having flow conduits and return conduits (14, 16; 68, 70) leading to and from the units,one or more circuits (12a-12c; 32-38; 74-78) located in the one or more units and connected to the flow conduits and return conduits (14, 16; 68, 70),at least one valve (28) provided in each circuit for adjusting a volumetric flow through each circuit,a heat transfer medium disposed in the conduit network,at least one consuming device (22) disposed in each circuit (12a-12c; 32-38; 74-78),a control unit (40) connected to the valves (28) located in each circuit for adjusting a passage opening of each valve (28) to achieve hydraulic balancing in the conduit network,sensors (38a, 38b) provided in each circuit (12a-12c; 32-38; 74-78), at least a first sensor (38a) located in a supply conduit for each circuit and at least a second sensor (38b) located in a return conduit for each circuit, the sensors (38a, 38b) sending signals to the control unit and forming part of a control circuit of the control unit (40), the control unit adjusting the valves (28) of each circuit as a function of the signals transmitted from the sensors (38a, 38b) to the control unit, for providing hydraulic balancing between the individual circuits (12a-12c; 32-38; 74-78), andwherein the valves (28) in each circuit (12a-12c; 32-38;74-78) form the only automatically adjustable flow restrictors of each circuit (12a-12c; 32-38;74-78), the flow restricted over a predetermined adjustment range of opening of each valve (28).
