Rotary heat exchangers can include a ride-along compressor, at least a portion of which can be rotated along with the heat exchanger. By rotating at least a portion of the compressor along with the heat exchanger, a sealed fluid circuit containing a two-phase working fluid can be provided. A rotary heat pump or heat engine can include an evaporator and a condenser in the form of back-to-back centrifugal fans. The centrifugal fan blades or other portions of the evaporator and condenser may include internal cavities where the working fluid undergoes a phase change.

An adjustable rotor support with a carrier beam configured to receive a center shaft of a rotor, at least one support brace connected to the carrier beam, and an adjustment arrangement operably connected to the support brace(s). The adjustment arrangement is configured to generate movement of at least one of the support brace(s), movement of the support brace(s) generating movement of the carrier beam along an adjustment axis (A1) perpendicular to a center axis (A2) of the center shaft. The adjustment arrangement is configured to lock the support brace(s) in a position reached through the movement such that the position is maintained by the adjustment arrangement during operation of the rotor.

Rotor, in particular a rotary heat pump, including a rotational axis, a number of compression ducts in which a working medium, in particular a gas, preferably a noble gas, is guided away from the rotational axis to increase the pressure due to the centrifugal acceleration, a number of expansion ducts in which the working medium is guided towards the rotational axis to reduce the pressure due to the centrifugal acceleration, a number of first heat transfer ducts for the working medium and a number of second heat transfer ducts for a heat transfer medium, in particular a liquid, so that heat is transferred between the working medium flowing in the first heat transfer ducts and the heat transfer medium flowing in the second heat transfer ducts, a number of first (10) and second rotor plates including the compression ducts, the expansion ducts, the first heat transfer ducts for the working medium and the second heat transfer ducts for the heat transfer medium, wherein the first and second rotor plates are connected to each other along their main planes of extension.
