TEMPERATURE ADJUSTER, SPECIFICATION AMBIENT TEMPERATURE CALCULATION METHOD, AND PROGRAM

To provide a temperature adjuster with which it is possible to ease the upper limit of a specification ambient temperature taking the actual state of use into account.SOLUTION: A temperature adjuster 10 comprises ambient temperature acquisition units, 70, 80, a component temperature detection unit 90, and a correction upper-limit ambient temperature calculation unit 60B. The ambient temperature acquisition units, 70, 80 acquire an ambient temperature Ta on the outside of a housing 10M of the temperature adjuster 10. The ambient temperature detection unit 90 detects a temperature Tp of a heat-generating component 40 that generates heat when operating inside of the housing 10M. The correction upper-limit ambient temperature calculation unit 60B calculates a correction upper-limit ambient temperature Tv usable by the temperature adjuster 10, using the ambient temperature Ta, the temperature Tp of the heat-generating component 40 when operating and a rated upper-limit temperature To of the heat-generating component 40.SELECTED DRAWING: Figure 2 【課題】実際の使用状態を考慮して、仕様周囲温度の上限を緩和することが可能な、温度調節器を提供する。【解決手段】温度調節器１０は、周囲温度取得部７０，８０と、部品温度検出部９０と、補正上限周囲温度算出部６０Ｂとを、備える。周囲温度取得部７０，８０は、温度調節器１０の筐体１０Ｍの外側の周囲温度Ｔａを、取得する。部品温度検出部９０は、筐体１０Ｍ内で動作時に発熱する発熱部品４０の温度Ｔｐを、検出する。補正上限周囲温度算出部６０Ｂは、周囲温度Ｔａと、発熱部品４０の動作時の温度Ｔｐと、発熱部品４０の定格上限温度Ｔｏとを用いて、温度調節器１０の使用可能な補正上限周囲温度Ｔｖを、算出する。【選択図】図２
