To provide a fluid temperature adjustment device which inhibits influence caused by change of a posture of a worker to secure a stable body temperature adjustment function.SOLUTION: A fluid temperature adjustment device 200 includes a circuit unit, a housing 30 which houses the circuit unit, and a fixture 40. The circuit unit includes: a cold heat circuit having a compressor 211 which retains lubrication oil in a refrigerant system and a heat exchanger which cools or heats a fluid； and a fluid circuit which sends the fluid cooled or heated by the heat exchanger to a body temperature adjustment outfit. The housing 30 has: a front surface part； a rear surface part facing the front surface part； a bottom surface part in which the compressor 211 is installed； and a pedestal part which is provided between the compressor 211 and the bottom surface part and inclines the compressor 211 a predetermined angle relative to a vertical direction in a direction from the front surface part to the rear surface part. The fixture 40 fixes the housing 30 to a wearer with the front surface part facing a back surface of the wearer in the body temperature adjustment outfit.SELECTED DRAWING: Figure 4【課題】作業者の姿勢変化による影響を抑えて、安定した体温調節機能を確保することができる流体温度調節装置を提供する。【解決手段】流体温度調節装置２００は、回路ユニットと、回路ユニットを収容する筐体３０と、固定具４０とを具備する。回路ユニットは、冷媒系統内に潤滑油を保有する圧縮機２１１と流体を冷却又は加熱する熱交換器とを有する冷熱回路と、熱交換器で冷却又は加熱された流体を体温調節服へ送出する流体回路とを含む。筐体３０は、前面部と、前面部と対向する後面部と、圧縮機２１１が設置される底面部と、圧縮機２１１と底面部との間に設けられ、圧縮機２１１を前面部から後面部に向かう方向へ鉛直方向に対して所定角度傾斜させる台座部とを有する。固定具４０は、前面部を体温調節服の着用者の背面に向けて筐体３０を着用者に固定する。【選択図】図４
