Active magnetic regenerator (AMR) refrigerators represent an alternative to vapor compression technology and have great potential in realizing cooling devices with high efficiency, which are highly desirable for a broad range of applications. The technology relies on the magnetocaloric effect in a solid refrigerant rather than the temperature change that occurs when a gas is compressed/expanded. This paper presents the general considerations for the design and construction of a high frequency rotary AMR device. Experimental results are presented at various cooling powers for a range of operating conditions near room temperature. The device exhibited a no-load temperature span of over 25 K and can absorb a 100 W cooling load at a 20.5 K temperature span.
► A rotary regenerator active magnetic regenerator refrigerator with operating frequencies up to 8 Hz is for the first time presented. ► A maximum no-load temperature of 25.4 K is reported, and a maximum cooling power over 1000 W when operating near zero span was measured. ► The device produces 100 W cooling at a temperature span of 20.5 K. ► The COP was measured and a value of 1.8 for at a 400 W load and an 8.9 K span is reported.
