The high and low temperature explosive decompression test chamber can be used for testing both heat-dissipating and non-heat-dissipating test specimens. For testing heat-dissipating test specimens, their heat dissipation power shall not exceed the cooling capacity of the refrigeration system of this test chamber. Since the control of temperature and humidity is a dynamic balance process, the cooling capacity of the refrigeration system also changes accordingly at different temperature and humidity points.<\/p>\n
