Abstract

　尿素水溶液タンク内の尿素水溶液の濃度を正確に識別するとともに、温度センサーによって測定された温度に基づいて、尿素水溶液の状態図（飽和溶解度曲線）に基づいて、その濃度における凝固点を正確に把握する。 　液体貯留タンクの凝固を防止するか、または、凝固した液体の全部または一部を融解する凝固防止装置であって、貯留液体の温度を識別する液温センサーと、貯留液体の物理量を測定する物理量測定センサーとを備え、物理量測定センサーを用いて、貯留液体に対応した物理量を測定することによって、液体貯留タンク内の貯留液体の凝固点を識別するように構成されている液体凝固点識別装置と、液体凝固点識別装置の貯留液体の凝固点の識別結果と、液温センサーによる貯留液体の温度に基づいて、液体貯留タンク内の貯留液体を加熱する加熱装置とを備えた。
