Heat pump cycle device

A heat pump cycle device is provided with a compressor (11), a branch section (12a), a heating section (13), heating section-side pressure reduction sections (14a, 14c), a bypass passage (21c), a bypass-side flow rate adjustment section (14d), a bypass (21c) converging section (12f), and an adjustment capability determination section (S3). Furthermore, when the adjustment capacity determination unit (S3) determines that the flow rate adjustment capacity of one of the heating unit-side pressure reduction units (14a, 14c) and the bypass-side flow rate adjustment unit (14d) is equal to or less than the reference adjustment capacity, the throttle opening degree of the other of the heating unit-side pressure reduction units (14a, 14c) and the bypass-side flow rate adjustment unit (14d) is set to be equal to or less than the upper limit opening degree. 热泵循环装置具备压缩机(11)、分支部(12a)、加热部(13)、加热部侧减压部(14a、14c)、旁通通路(21c)、旁通侧流量调节部(14d)、旁通(21c)合流部(12f)、以及调节能力判定部(S3)。并且，当通过调节能力判定部(S3)判定为加热部侧减压部(14a、14c)和旁通侧流量调节部(14d)中的一方的流量调节能力
