Abstract
A refrigeration cycle device including a first pressure reducing valve, a first evaporator that exchanges heat between the refrigerant decompressed in the first pressure reducing valve and air, a second pressure reducing valve that is disposed in parallel with the first pressure reducing valve; a second evaporator in which the refrigerant decompressed in the second pressure reducing valve to absorbs heat from a battery; a third pressure reducing valve that reduces the pressure of the refrigerant evaporated in the second evaporator; and a controller configured to control opening degrees of the second pressure reducing valve and the third pressure reducing valve. The controller performs a limit control for controlling the opening degree of the second pressure reducing valve to an opening degree of smaller one of a battery cooling opening degree and an air cooling opening degree.
