1. A temperature control system for a vehicle, comprising:
a main circuit comprising a tubing in which there is provided a coolant, a main circuit pump configured to pump said coolant through a tubing of the main circuit in a first direction, and at least one unit for cooling or heating the coolant in the main circuit;
a first sub-circuit for cooling or heating a first component, said first sub-circuit comprising a tubing that has a first end and a second end, which are connected to respective openings in the tubing of the main circuit at positions that are spaced apart from each other as seen in a longitudinal direction of the tubing of the main circuit, wherein the first end is connected to the tubing of the main circuit at a position upstream of the position at which the second end is connected to the tubing of the main circuit as seen in said first direction;
at least one second sub-circuit for cooling or heating a second component, said at least one second sub-circuit comprising a tubing that has a first end and a second end, which are connected to respective openings in the tubing of the main circuit at positions that are spaced apart from each other as seen in a longitudinal direction of the tubing of the main circuit, wherein the first end is connected to the tubing of the main circuit at a position upstream the position at which the second end is connected to the tubing of the main circuit as seen in said first direction,
wherein the first sub-circuit comprises a first pump configured to pump a coolant in a direction from said first end of the tubing of the first sub-circuit to the second end thereof,
wherein the at least one second sub-circuit comprises a second pump configured to pump a coolant in a direction from said first end of the tubing of the at least one second sub-circuit to the second end thereof, and
wherein the first end of the first sub-circuit and the first end of the at least one second sub-circuit are joined to a common tubing section which in its turn is connected to the tubing of the main circuit; and
a control unit configured in at least one mode to control an output, as measured in volume per time unit, of each of the main circuit pump, the first pump of the first sub-circuit, and the second pump of the at least one second sub-circuit, such that a sum of an output of the first pump of the first sub-circuit and an output of the second pump of the at least one second sub-circuit exceeds an output of the main circuit pump.
