[0002] In today's energy and environmental fields, adsorbent refrigeration technology is emerging, demonstrating enormous potential. In recent years, it has been widely used in key areas such as industrial refrigeration and thermal stabilization of permafrost roadbeds and foundations. With its unique advantages, adsorbent refrigeration technology offers a new approach to addressing the environmental and energy consumption challenges associated with traditional refrigeration methods. In industrial refrigeration, it can achieve efficient cooling within a specific temperature range, meeting the low-temperature requirements of various industrial production processes. For thermal stabilization of permafrost roadbeds and foundations, adsorbent refrigeration technology effectively regulates the temperature of the frozen ground, preventing thawing and ensuring the stability of the roadbed and foundation, thus playing a vital role in safeguarding transportation infrastructure.

[0018] Specific working principle: like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, when the adsorption refrigeration cycle durability test device is used, the heat transfer oil medium inside the heat absorption refrigeration constant temperature barrel 30 is heated by the temperature regulating intelligent controller 63, so that the refrigerant poured into the heat absorption refrigerator 1 undergoes a phase change from liquid to vapor. The heat transfer oil medium inside the hot and cold alternating constant temperature barrel 45 is lowered by the temperature regulating intelligent controller 63, so that the adsorbent temperature inside the hot and cold alternating adsorption bed 2 is lowered, and the refrigerant gas vaporized from the heat absorption refrigerator 1 is continuously adsorbed. Then, the temperature regulating intelligent controller 63 is used to adjust the heat transfer oil medium inside the hot and cold alternating constant temperature barrel 45. The heat transfer oil medium in the hot and cold alternating constant temperature barrel 45 is heated to increase the temperature of the adsorbent in the hot and cold alternating adsorption bed 2, and the refrigerant adsorbed by the adsorbent in the hot and cold alternating adsorption bed 2 is desorbed and vaporized. The desorbed refrigerant from the hot and cold alternating adsorption bed 2 enters the interior of the intelligent temperature control condenser 3 through the desorption connecting pipe 52 and the ventilation check valve 20 in the intelligent temperature control condenser 3. The temperature of the heat transfer oil medium in the intelligent temperature control barrel 51 is reduced by the temperature regulating intelligent controller 63, and the intelligent temperature control condenser 3 is cooled at the same time, so that The refrigerant adsorbed by the adsorbent inside the hot and cold alternating adsorption bed 2 desorbs the refrigerant gas and is converted into liquid refrigerant, which is fully cooled by the throttling effect of the twelfth interface 56 in the liquid reservoir 4. The liquid refrigerant flowing out of the twelfth interface 56 in the liquid reservoir 4 flows back into the heat absorption refrigerator 1 through the refrigeration connecting pipe 53 to complete the refrigeration cycle. During the system circulation process, the reading of the liquid level gauge 7 in the heat absorption refrigerator 1, as well as the readings of the system pressure gauge 13 and the system vacuum gauge 16 in the heat absorption refrigerator 1, the desorption connecting pipe 52 and the refrigeration connecting pipe 53 and other components, as well as the thermometer and other test components are recorded in detail to determine the optimal cycle time, debug the switching time of the temperature adjustment intelligent controller 63 installed in the heat absorption refrigeration constant temperature barrel 30, the hot and cold alternating constant temperature barrel 45, and the intelligent temperature control barrel 51, accelerate the number of refrigeration cycles, and fully test the adsorption refrigeration durability efficiency test.
