TEST CHAMBER Russian patent published in 2011 - IPC G01M1/00 

FIELD: physics.

SUBSTANCE: apparatus chamber has a housing in which there are sensors of parametres of the test object, a cooling system, a heating system, a ventilator and a door for loading the test object. Outputs of the sensors of parametres of the test object are connected to inputs of a control unit, whose outputs are connected to control inputs of the cooling system, the heating system and the ventilator. Air from the ventilator is fed by one or more flexible perforated air ducts whose length is sufficient for supplying air to any part of the chamber depending on the configuration of the test object.

EFFECT: temperature uniformity due to guaranteed circulation of air in the entire volume and absence of stagnant areas.
