Abstract

Provided is a heat pump device wherein noises generated during a partial load operation can be easily insulated. The heat pump device is comprised of a turbo compressor (6) which compresses a refrigerant; a condenser (2) which condenses the compressed refrigerant; an expansion valve (3) which adiabatically expands the condensed refrigerant; an evaporator (4) which evaporates the adiabatically-expanded refrigerant; a container (5) to which the evaporated refrigerant is introduced, and through which the introduced refrigerant is discharged to the turbo compressor (6); a noise insulation portion (51) which surrounds the periphery of the container (5), and prevents noises generated within the container (5) from leaking to the outside; a bypass passage (8) through which a part of the refrigerant passing between the turbo compressor (6) and the condenser (2) is introduced to the container (5); and a flow rate control portion (9) which controls the flow rate of the refrigerant passing through the bypass passage.
