The paper presents a preliminary experimental study of the precooled MR JT cryocooler, which was designed for LNG recondensation and potentially liquefaction purposes. The paper also includes the most vital aspects of the design: compressor selection and limitations, selection and size of expansion devices, effect of MR composition on the stability of the load temperature, and minimum approach during recuperation. In addition, a detailed description of the features of the test stand is provided. A series of experimental tests has been performed with varied heat load, suction pressure, discharge pressure, and precooling temperature. The cryocooler provided cooling power of 270 W at a temperature of -158℃, which is the largest MR JT cryocooler reported in the literature. Experiments indicate an optimum precooling temperature similar to that derived from the theoretical study (approximately -35℃).
