This concept is making space accessible, affordable, and reliable, especially for new entrants in the space field. One of the ways to achieve this is making environmental testing of satellites inexpensive. We present in this paper, the performance evaluation of a comparatively inexpensive thermal vacuum testing system, equipped with a thermoelectric device that uses the Peltier principle of heat generation and/ or absorption. The thermoelectric device is a commercial-off-the-shelf (COTS) component with a cooling capacity of 16.9 W. The testing system does not require liquified nitrogen or silicon oil for simulating cold conditions. In addition, the testing system is capable of vacuum thermal cycling and balancing tests within -45 ℃ to +75 ℃, well beyond the minimum requirements of the ISO-19683. These characteristics make the testing system simple, reproducible, and affordable. We evaluated performance parameters of the Peltier device as functions of cold side temperature., 33rd International Symposium on Space Technology and Science (ISTS), February 26-March 4, 2022, Beppu, Japan(オンライン開催に変更)}, title = {Performance evaluation of thermoelectric device for thermal vacuum testing of nanosatellites}, year = {2022}, yomi = {マスイ, ヒロカズ and チヨウ, メンウ} }
