- the actual rotation speed ⁇ power is large, the amount of protrusion of the rod cover (81) with respect to the medium temperature space (35) is reduced, the change ib in the rod volume is reduced, and the shaft output Wt is reduced to reduce Lower.
- the auxiliary motor (4a) is stopped and there is no auxiliary power, the rotation speed N is reduced.
- step ST21 the rod cover (81) is raised from the state shown in FIG. 3 by driving the adjusting motor (82) by the control signal from the controller (92), and the process returns to step ST17.
- the actual rotation speed N is small, the amount of protrusion of the rod cover (81) with respect to the medium temperature space (35) is increased, the change in rod volume ibS is increased, and the shaft output Wt is increased to increase the self-standing point S. .
- the auxiliary drive motor (4a) is stopped and no reverse load acts at present, the rotation speed is increased by N.
- the self-standing point S is adjusted by changing the rod volume of the low-temperature medium-temperature space (35).
- the drive speed of the displacer (22, 32) can be made to match the set speed without acting on the motor.
- FIG. 21 shows an embodiment of another volume adjusting means (8b), which adjusts the capacity itself of the low temperature side medium temperature space (35).
- the volume adjusting means (8b) is configured by connecting the means (89) to the annular body (88).
- the annular body (88) is formed in a cylindrical shape, and the annular groove of the crankcase (41) is formed. Inserted in (48).
- the annular groove (48) is formed so as to open to the low temperature side medium temperature space (35), and the annular body (88) is provided so as to be able to protrude and retract into the low temperature side medium temperature space (35).
- volume control means (9c) is connected to the drive means (89).
- the volume control means (9c) has the same configuration as the rod volume control means (9a) shown in FIG. It comprises a rotation speed detector (91) and a controller (92). Then, the controller (92) calculates the volume of the medium temperature space (35) corresponding to the rotation speed N of the crankshaft (42), derives the position of the annular body (88), and derives the position of the annular body (88).
- the annular body (88) rises and increases the amount of protrusion of the medium temperature space (35) in FIG. 21 when the rotation speed N force increases, while it lowers when the rotation speed N decreases. It is configured to reduce the amount of protrusion from the medium temperature space (35).
- the volume control means (9c) adjusts the position of the annular body (88) and adjusts the rotation speed N of the crankshaft (42) as in the rod volume control means (9b) shown in FIG. It may be one that performs one-back control.
- the rod volume adjusting means (8a) is not limited to the rod cover (81) or the like, but can change the rod volume by changing the rod diameter or the like. Anything can be used.
- the Vilmier heat pump device can perform efficient operation by changing the temperature of the medium-temperature space, and thus can be used for an air conditioner that performs cooling and heating operation using cold and hot water. Suitable for.
