Abstract (en)
[origin: WO2021165123A1] An apparatus for generating a temperature-controlled cold gas stream, having a storage tank and an extraction line which is connected to the storage tank and which serves for the extraction of liquefied gas from the storage tank, and having an evaporator unit which is integrated in the extraction line and which is equipped with a heat exchanger surface for the indirect thermal contact of the liquefied gas with a heat carrier fluid, is characterized according to the invention in that a liquid line branches off from the extraction line downstream of the storage tank and upstream of the evaporator unit, which liquid line opens into the extraction line downstream of the evaporator unit at an introduction device, wherein the introduction device is equipped with a sensor for detecting the temperature in the extraction line and with a control valve which is operatively connected to the sensor and which serves for controlling the introduction of liquefied gas into the extraction line.
