To provide a space environment testing device capable of efficiently supplying a low temperature liquefied gas in a gaseous state or in a liquid state, into shrouds disposed inside a chamber.SOLUTION: A space environment testing device 1 comprises: a chamber 2; shrouds 3 disposed inside the chamber 2; a head tank 4 disposed at a position above the shrouds 3 in a vertical direction; a circulation path L1 in which a low temperature liquefied gas is circulated between the head tank 4 and the shrouds 3; and a control device 6 which holds supply pressure of the low temperature liquefied gas at a first target pressure value higher than atmospheric pressure, when supplying the low temperature liquefied gas in a liquid state to the shrouds 3, and which holds supply pressure of the low temperature liquefied gas at a second target pressure value higher than the first target pressure value, when supplying the low temperature liquefied gas in a gaseous state to the shrouds 3.SELECTED DRAWING: Figure 1

    【課題】チェンバー内に設けられたシュラウド内に、気体状態又は液体状態の低温液化ガスを効率よく供給することが可能な宇宙環境試験装置を提供する。【解決手段】チェンバー2と、チェンバー2の内側に設けられたシュラウド3と、鉛直方向においてシュラウド3よりも高い位置に設けられたヘッドタンク4と、ヘッドタンク4とシュラウド3との間に低温液化ガスを循環させる循環経路L1と、シュラウド3に液体状態の低温液化ガスを供給する際に、低温液化ガスの供給圧力を大気圧よりも高い第1目標圧力値に保持するとともに、シュラウド3に気体状態の低温液化ガスを供給する際に、低温液化ガスの供給圧力を第1目標圧力値よりも高い第2目標圧力値に保持する制御装置6と、を備える宇宙環境試験装置1を選択する。【選択図】図1
