[Problem] Mainly to enable a healthy life. A blood pressure estimating unit (4) for obtaining a blood pressure change curve (3) showing changes in blood pressure with temperature based on a plurality of blood pressure measurement values (2a, 2b) measured at different temperatures, and a blood pressure change obtained by the blood pressure estimating unit (4). Air conditioning control including a presentation unit 6 that presents a temperature 5 at which the blood pressure decreases according to the curve 3, and an air conditioning condition setting unit 9 that sets a temperature 8 of the air conditioning equipment 7 based on the temperature 5 presented by the presentation unit 6. Regarding system 1. The blood pressure estimation unit 4 may include a data correction unit 21 that corrects the blood pressure change curve 3 using the blood pressure measurement values 2a and 2b when the temperature 5 presented by the air conditioning condition setting unit 9 is reached. [Selection diagram] Fig. 1【課題】主に、健康的な暮らしなどができるようにする。【解決手段】異なる温度で測定された複数の血圧測定値2a,2bに基づいて、温度による血圧の変化を示す血圧変化曲線3を求める血圧推定部4と、 血圧推定部4で求めた血圧変化曲線3に従って血圧が低くなる温度5を提示する提示部6と、 提示部6によって提示された温度5に基づいて空調機器7の温度設定8を行う空調条件設定部9と、を備えた空調制御システム1に関する。 血圧推定部4は、空調条件設定部9で提示された温度5になった時の血圧測定値2a,2bを用いて血圧変化曲線3を補正するデータ補正部21を備えても良い。【選択図】図1
