Type of article: Article, IJR article

Summary

A new kind of heat pump is described derived from the Vuilleumier process which has been known since 1918 but not applied until 1960 for small refrigerators down to 80 K. It consists of two oscillating displacers connected 90° out of phase and in parallel with thermal regenerators. It is pressurized by helium or hydrogen gas to 30-60 bars (3-6x108 N m-2) and runs at 750 to 1500 rpm. The calculated heating power for a model of 1000 cm3 swept volume, taking heat in at 500°C and allowing for losses, will be 4 to 6 kW and a COP between 1.6 and 2.
