Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat pump heat source device preventing occurrence of chattering sound from a defrosting valve by avoiding increase in cost of a valve component and complication of the device.SOLUTION: A back pressure countermeasure part 72, when a temperature Tm1 of a heat medium in a heat medium pipeline 20 in an expander 23 detected by a temperature sensor 35 is higher than a temperature Twin of water supplied from a tank circulation path 41 to the expander 23 detected by a temperature sensor 43 by a predetermined temperature or more, opens a defrosting solenoid valve 26.SELECTED DRAWING: Figure 1 【課題】除霜弁からのビビリ音の発生を、弁部品のコストの増大及び装置の複雑化を回避して防止したヒートポンプ熱源装置を提供する。【解決手段】逆圧対処部７２は、温度センサ３５により検出される膨張器２３における熱媒配管２０内の熱媒の温度Ｔm1が、温度センサ４３により検出されるタンク循環路４１から膨張器２３に供給される水の温度Ｔwinよりも所定温度以上高くなっているときに、除霜電磁弁２６を開弁する。【選択図】図１
