The purpose of the present invention is to provide a low-cost heat cycle system capable of reducing power consumption, an in-wheel motor driven by the heat cycle system, and a vehicle equipped with the heat cycle system. This heat cycle system (400) is provided with a compressor (100), an accumulator (501), an electric drive unit (200) comprising an electric motor (210), a refrigerant compressed by the compressor (100), and an indoor heat exchanger (321) and an outdoor heat exchanger (311) for heat exchange of the refrigerant. A heat cycle system (400) is provided with a four-way valve (102) which is configured from a single circulation path for circulating a refrigerant and which is capable of switching the connection destination of a refrigerant discharge unit of a compressor (100) to an indoor heat exchanger (321) or an outdoor heat exchanger (311), and a cooling unit (211) of an electric drive unit (210) is disposed on the upstream side of an accumulator (501) during the flow of the refrigerant.
本发明的目的在于提供一种能够降低电力消耗且低成本的热循环系统、利用该热循环系统驱动的轮内马达以及搭载有该热循环系统的车辆。本发明的热循环系统(400)具有:压缩机(100)、储液器(501)、由电动机(210)构成的电驱动部(200)、由压缩机(100)压缩的制冷剂、以及承担制冷剂的热交换的室内热交换器(321)和室外热交换器(311),热循环系统(400)具有由使制冷剂循环的单一循环路径构成且能够将压缩机(100)的制冷剂喷出部的连接目的地切换为室内热交换器(321)或室外热交换器(311)的四通阀(102),电驱动部(210)的冷却部(211)在制冷剂的流动中配置于储液器(501)的上游侧。
