Heat pump device

A heat pump device comprising:

• a heat source equipment that produces heated water by a heat source;
• a radiation terminal that is connected to the heat source equipment and that adjusts a temperature of an indoor space by radiation heat that is obtained by flowing the heated water from the heat source equipment into a radiation panel;
• a forced convection terminal that is connected to the heat source equipment, flows the heated water from the heat source equipment into a use-side heat exchanger, and blows air on which heat exchange with the heated water is performed by the use-side heat exchanger using a blast fan and thus adjusts the temperature of the indoor space;
• and
• a control device that controls the heat source equipment, the radiation terminal, and the forced convection terminal,
• wherein the control device includes a controller that, when the radiation terminal and the forced convection terminal are operated at a time, controls the forced convection terminal to reduce an air volume of the forced convection terminal compared to an air volume in a case where only the forced convection terminal is in operation.
