To provide a heat cycle system which can reduce electric power consumption and has a low cost, provide an in-wheel motor driven by utilizing the heat cycle system, and provide a vehicle on which the heat cycle system is mounted.SOLUTION: A heat cycle system 400 includes a compressor 100, an accumulator 501, an electric drive part 200 comprising an electric motor 210, coolant compressed by the compressor 100, and an indoor heat exchanger 321 and an outdoor heat exchanger 311 which bear heat exchange of coolant. The heat cycle system 400 comprises a single circulation path which circulates the coolant, and has a four-way valve 102 capable of switching a connection destination of a coolant discharging part of the compressor 100 to the indoor heat exchanger 321 or the outdoor heat exchanger 311. A cooling part 211 of the electric driving part 210 is arranged on the upstream side of the accumulator 501 on a flow of the coolant.SELECTED DRAWING: Figure 2A

    【課題】本発明の目的は、電力消費を低減可能でかつ低コストな熱サイクルシステム、この熱サイクルシステムを利用して駆動されるインホイールモータならびにこの熱サイクルシステムを搭載した車両を提供することにある。【解決手段】本発明の熱サイクルシステム400は、圧縮機100と、アキュムレータ501と、電動機210から成る電気駆動部200と、圧縮機100によって圧縮される冷媒と、冷媒の熱交換を担う室内熱交換器321および室外熱交換器311と、を備え、熱サイクルシステム400は、冷媒を循環させる単一の循環経路から成り、かつ、圧縮機100の冷媒吐部の接続先が室内熱交換器321または室外熱交換器311に切り替え可能な四方弁102を有しており、電気駆動部210の冷却部211は、冷媒の流れにおいてアキュムレータ501の上流側に配置されている。【選択図】図2A
