| description | The use of -80 ℃ low-temperature cold storage is increasing in blood stations, hospitals, and medical research institutions. Low-temperature cold storage primarily uses traditional cascade refrigeration systems. In this paper, Stirling refrigeration is used to cool a -80 ℃ low-temperature cold storage. The Stirling refrigerator provides high-efficiency performance at low temperatures; low-temperature cold storage with a volume of 1500 L at -80 ℃ was designed. The structural characteristics of the low-temperature cold storage were analyzed, and the composite insulation layer with a vacuum insulation panel (VIP) and polyurethane was studied. Calculation methods for the heat load of low-temperature cold storage were presented. Based on the experimental performance of the Stirling refrigerator, the feasibility of the design scheme was verified. A single Stirling refrigerator can reach a cooling temperature of -80 ℃ in less than 10 min under no-load conditions with 200 W of input power; the minimum cooling temperature was stable at approximately -160 ℃ after 50 min, with a cooling capacity of 180 W with 500 W of input power, corresponding to a COP of 0.36. This research provides theoretical guidance for future ultra-low temperature cold storage with Stirling refrigerators. |
