EVAPORATOR

PROBLEM TO BE SOLVED: To provide an evaporator arranged in a refrigeration cycle in which a compressor is controlled to be turned on or off, and capable of preventing the generation of odor resulting from a response delay of a temperature sensor as much as possible.SOLUTION: An evaporator 6 arranged in a steam compression refrigeration cycle 2 in which a compressor 3 is turned on or off on the basis of a temperature sensor 12 that detects a downstream temperature of the evaporator 6, and cooling air flowing outside with a refrigerant flowing in the evaporator 6 when the compressor 3 is turned on, comprises a cold storage agent. The cold storage agent has a freezing point in a temperature range equal to or higher than a temperature exceeding a water freezing temperature and lower than a temperature at which condensed water adhering to the evaporator 6 is evaporated and dried. 【課題】圧縮機がオンオフ制御される冷凍サイクルに配置されるものにあって、温度センサの応答遅れに起因する臭いの発生を極力防止できる蒸発器を提供する。【解決手段】蒸発器６下流側の温度を検知する温度センサ１２に基づいて圧縮機３がオンオフする蒸気圧縮式冷凍サイクル２に配置され、圧縮機３のオン時には冷媒が内部を流れて外部を流れる空気を冷却する蒸発器６であって、蓄冷剤を有し、蓄冷剤は、水の凍結温度を超える温度以上で、且つ、蒸発器６表面に付着した凝縮水が蒸発して乾く温度未満の範囲に凝固点を有する。【選択図】図１
