The direct cooling rapid temperature change test chamber adopts the compressor refrigeration system to directly cool down the interior of the test chamber, combined with a highly efficient heating system to realize the rapid rise and fall of temperature. Its core refrigeration principle is based on the inverse Carnot cycle, through the process of compression, condensation, expansion and evaporation of refrigerant, absorbing the heat inside the box and transferring it to the external environment, thus realizing rapid cooling.
