Description
Adsorption refrigeration is a significant method for achieving temperatures below 1 K. The process involves pumping a helium tank to a high vacuum by adsorbents, resulting in the liquid helium reaching sub-Kelvin temperatures. The adsorbents are then heated to desorb 4He, which condenses in the region below the critical temperature, and the adsorption refrigeration cycle is repeated. This paper presents the design and experiments of a 4He sub-Kelvin adsorption cooler that can achieve an ultra-temperature of 773 mK, continuously refrigerate for 9.4 hours without any additional heat power, and has a cooling power of 100 μW at 803 mK.
