Abstract (en)

[origin: US2011197616A1] A heat pump apparatus that can easily prevent noise generated during partial-load operation is provided. The heat pump apparatus includes a centrifugal compressor configured to compress a refrigerant; a condenser configured to condense the compressed refrigerant; an expansion valve configured to adiabatically expand the condensed refrigerant; an evaporator configured to vaporize the adiabatically-expanded refrigerant; a container into which the vaporized refrigerant flows and from which the refrigerant that flowed in flows out to the centrifugal compressor; a sound-insulating member configured to cover the container and prevent sound generated inside the container from leaking outside; a bypass channel configured to guide part of the refrigerant from an area between the centrifugal compressor and the condenser to the container; and a flow control valve configured to control the flow rate of the refrigerant flowing through the bypass channel.
