DOMESTIC APPLIANCE FOR DRYING A HUMID PRODUCT, COMPRISING A COOLING ASSEMBLY AND A HEATING ASSEMBLY

摘要

A domestic appliance for drying a damp product by means of a process air stream that is conducted in a process air channel. The appliance has a treatment chamber that includes the damp product. A cooling assembly cools and condenses the process air stream after it flows through the treatment chamber. A first heat exchanger supplies heat from the process air stream to a working fluid. A heating assembly heats the process air stream before it flows through the treatment chamber and a second heat exchanger supplies heat from the working fluid to the process air stream. The working fluid is conducted in a heat pump that has at least two mechanically coupled displacement pistons. The heat pump operates according to a regenerative gas cycle process that includes a Vuilleumier gas cycle process.
