DEHUMIDIFIER

To perform an emergency operation according to the residual amount of a heating medium, in the case where it is detected that the amount of the heating medium in a refrigeration cycle is decreasing.SOLUTION: A dehumidifier includes: a blower fan installed in a housing, and for taking in the indoor air into the housing; a dehumidification device installed in the housing, and for performing dehumidification of the air taken in the housing, by a refrigeration cycle in which a compressor, a condenser, a decompression device, and an evaporator are connected by a heating medium circuit and a heating medium is circulated; indoor temperature detection means for emitting an output according to the temperature of the indoor air; heating medium temperature detection means for emitting an output according to the temperature of the heating medium in the evaporator; and a control device. The control device executes control for lowering the temperature of the heating medium in the evaporate, in the case where a temperature difference which is a difference between the temperature of the heating medium detected by the heating medium temperature detection means during the drive of the compressor and the temperature of the indoor temperature is smaller than a threshold value.SELECTED DRAWING: Figure 6 【課題】冷凍サイクル内の熱媒体の量が減少していることを検知した場合に、熱媒体の残量に応じた応急的な運転を行う。【解決手段】本開示の除湿機は、筐体内に設置され、室内空気を筐体内に取り込む送風ファンと、筐体内に設置され、圧縮機と凝縮器と減圧装置と蒸発器とを熱媒体回路で接続して熱媒体を循環させた冷凍サイクルにより、筐体内に取り込まれた空気の除湿を行う除湿装置と、室内空気の温度に応じた出力を発する室温検出手段と、蒸発器内の熱媒体の温度に応じた出力を発する熱媒体温度検出手段と、制御装置とを備える。制御装置は、圧縮機の駆動中に熱媒体温度検出手段により検出される熱媒体の温度と、室内空気の温度との差である温度差が、閾値より小さい場合には、蒸発器内の熱媒体の温度を低下させる制御を実行するように構成されている。【選択図】図６
