Summary

This paper describes the cascade type non-flammable mixed refrigerant (MR) Joule Thomson (JT) refrigerator for the cooling temperature of 100 K. The working fluid for non-flammable MR JT refrigerator is a mixture of Nitrogen, Argon, Tetrafluoromethane (R14, CF4) and Octafluoropropane (R218, C3F8). Experimental work is performed to confirm the design result of the cascade MR JT refrigerator. The lowest temperature is approximately 98.5 K and the maximum cooling capacity records 15 J/g at the 103 K, which is the normalized value with respect to the mass flow rate of the working fluid. The pressure drop at the low pressure side is a critical role to reduce the refrigeration efficiency.
