Abstract
【解決手段】 冷凍サイクルを構成する蒸発器13に試験室1内の空気を循環させて、試験室1内の温度と湿度を制御する冷凍機を備えた調温調湿装置において、蒸発器13における冷媒の蒸発温度を調整して蒸発器13の蒸発温度の検出値を着霜温度を超える温度に設定された設定温度に調整することにより、周囲温度の変化などの外乱があっても、蒸発温度が着霜しない設定温度に維持されるから、試験室1内の温度および湿度を安定に長時間制御できる。また、蒸発温度を設定温度に維持するように蒸発温度を可変制御するから、設定温度を着霜温度に近づけて設定しても着霜を防止でき、ノーフロスト運転の領域を低温度側、および低湿度側に拡大することができる。
