摘要：The present invention realizes a reliable heat pump apparatus and heat pumpapparatus having high recovering efficiency. The heat pump apparatus includes anexpander for expanding working fluid, a permanent magnet type synchronization power
generator which is disposed for recovering power by the expander and which generatesthree phase AC power, and a first converter which converts the AC power to DC power,and which rotates the power generator at a predetermined target number of revolutionsby switching of a switching element group . The generated electricity is consumed byconnection of an AC power supply to a DC power line which is rectified and smoothenedby a rectifier circuit and a smoothing capacitor , and by driving of an electric motor whichrotates a compressor through a motor drive apparatus , and the power is efficientlyrecovered.
