Abstract
A test bench conditioning system for a working fluid of a machine located on the test bench includes at least one pump (3) for circulating the working fluid, a heat exchanger (4) for cooling the working fluid coming from the discharge line (1) of the machine and a heating device (5) for the working fluid fed into the supply line (2) to the machine and a mixing valve (6). Furthermore, a bypass (8) that can be shut off between the discharge line (1) and the supply line (2) can be provided. Setting a temperature profile for the working fluid is possible via a control device. In order to render possible an optimum simulation of a real temperature profile of an operating fluid of a machine with the slightest deviations for the predetermined profile, a connecting line (10) with a control valve (11) leads to the discharge line (1) in front of the mixing valve (6), which opens into this discharge line (1) in front of the pump (3).
