摘要： In a thermally regulated climate chamber for testing equipment, a thermoelectric unit is arranged through the wall of the climate chamber, each thermoelectric unit having two faces, an internal face inside the climate chamber and an external face outside the climate chamber, wherein a heat exchange end for an external face of a thermoelectric unit of a secondary thermal regulation circuit is placed in thermal contact with each external face of thermoelectric unit, the secondary thermal regulation circuit being external to the climate chamber and including a heat-transfer fluid circuit, a cold source, a hot source, a mixing device, a circulation pump and sensors. A chamber temperature regulation system controls the electric current of the thermoelectric unit and to control at least the mixing device and the circulation pump of the secondary thermal regulation circuit as a function of a chamber temperature setpoint and of sensor measurements.
