Abstract: To condition an operating medium in a test object circuit (PK) of a test object (P) on a test bench to a desired temperature as quickly as possible, the invention proposes providing a mixing unit (3), there being provided, in the mixing unit (3), a mixing region (28) in which operating medium of the test object circuit (PK) can be mixed with preconditioned operating medium from a conditioning circuit (KK) in order to condition the operating medium in the test object circuit (PK) to the predefined setpoint temperature (T_SOLL), there being provided, on the mixing unit (3), for the fluidic integration of the mixing unit (3) in the test object circuit (PK), at least one test object circuit supply connection (26a) and at least one test object circuit outlet connection (26b) which are fluidically connected to one another via the mixing region (28) in order to form a part of the test object circuit (PK), there being provided, on the mixing unit (3), for connection of the mixing unit (3) to a conditioning unit (2) o

Abstract: A conditioning device for regulating a gaseous or a liquid fluid to a constant target temperature includes an inlet fluidically connected to a supply system, an outlet fluidically connected to a consumer, a first fluid line arranged between the inlet and outlet, a heater arranged in the first fluid line, a second fluid line arranged to branch off from the first fluid line upstream of the heater and to open out into the first fluid line downstream of the heater, a regulating valve which regulates a fluid flow arranged either in the first fluid line or in the second fluid line, a temperature sensor arranged in the first fluid line downstream of where the second fluid line opens out into the first fluid line, and a check valve arranged either in the first fluid line or in the second fluid line in which the regulating valve is not arranged.

Abstract: The invention relates to a method and to a device for calibrating a pump (1) provided in a pump line (6), the device comprising an actuator (2) for setting the pumping capacity of the pump (1), and a control unit (3). The device comprises a flow monitor (4) in the fuel line (6). The control unit (3) is designed to substantially steadily vary the controlled variable of the actuator (2), when starting the pump (1), up to the switch point (SP) of the flow monitor (4), and to ascertain and store a controlled variable associated with the respective switch point (SP), to ascertain a controlled variable difference value (?f) between a reference controlled variable (fR) stored for the pump (1) and the flow monitor (4) and a calibration controlled variable (fK) ascertained during the calibration, and to calibrate the controlled variable of the actuator (2) of the pump (1) based on the controlled variable difference value (?f).

Abstract: The invention relates to a conditioning unit (3) comprising a base body (20) and a buffer storage (21), wherein a medium is supplied through the base body (20) and a temperature control unit (23) having a first heating surface (24) and a second heating surface (25) is arranged between the buffer storage (21) and the base body (20), and wherein a temperature spread is set between the first heating surface (24) and the second heating surface (25) by means of the temperature control unit (23).

Abstract: For a temperature control unit for gaseous or liquid medium with a highly dynamic temperature regulation of the medium, the temperature control unit is designed with a base body and a cooling body between which are arranged multiple thermoelectric modules, and with a media line in the base body, wherein the media line is arranged in the base body in the form of a single-start spiral from the outside to the inside, and it is provided that the multiple thermoelectric modules are arranged in a plurality of rows on the base body, wherein the module heating power of a thermoelectric module situated further toward the outside radially is greater than the module heating power of a thermoelectric module situated further toward the inside radially.
