Stirling heat pump with resonance tube: a supercharged Vuilleumier process.

Author(s) : BUDLIGER J. P.


A new concept for a thermally driven Stirling heat pump system has been developed, which corresponds to a Vuilleumier unit with an attached resonance tube. The latter serves to amplify the pressure wave in the system and thus to create a supercharging effect in the Vuilleumier unit. Primary application is for domestic heating, where energy savings of 35 to 40% can be realised as compared to conventional heating systems. The developed concept may also be used for cooling or air conditioning by means of fossil fuel. An experimental prototype unit has been built and tested. The system operated in a predictable and stable mode. The obtained results are presented and the prospects of these systems are discussed. Particular emphasis is put on the remarkable operating flexibility under part-load conditions and on the benefits resulting from the use of gaseous fuels.
