To provide vehicle-mounted refrigeration equipment enabling heat generated in the equipment to be efficiently utilized for heating the inside of a vehicle.SOLUTION: Vehicle-mounted refrigeration equipment comprises: a refrigeration machine 10 which includes a compressor 11 compressing a refrigerant, a heat exchanger 12 exchanging heat between the refrigerant and a heating medium heating the blown air, a condenser 13 exchanging heat between the refrigerant and outside air from outside a freezer, a condenser fan 13a blowing the outside air toward the condenser, and an evaporator 16 exchanging heat between the refrigerant and the air inside the freezer; and a control device 20 that controls the operation of the compressor and the condenser fan, and switches the operation of the refrigeration machine. The operation modes include a refrigeration operation for cooling the interior of the freezer, and a heating assist operation using a part of the heat generated by the refrigeration machine in the heating operation of a vehicle air conditioning device. When performing the heating assist operation, the control device reduces the rotational speed of the compressor and reduces the rotational speed of the condenser fan compared to a case in which the refrigeration operation is performed.SELECTED DRAWING: Figure 1
【課題】発生する熱を効率よく車室内の暖房に用いることが可能な車載用冷凍装置を提供すること。【解決手段】車載用冷凍装置は、冷媒を圧縮するコンプレッサ11と、冷媒と送風空気を加熱する熱媒体とを熱交換させる暖房用熱交換器12と、冷媒と冷凍庫外の外気とを熱交換させるコンデンサ13と、コンデンサに向けて外気を送風するコンデンサファン13aと、冷媒と冷凍庫内の空気とを熱交換させるエバポレータ16と、を含む冷凍機10と、コンプレッサおよびコンデンサファンの動作を制御し、冷凍機の運転を切り替える制御装置20と、を備える。運転モードは、冷凍庫内を冷却する冷凍運転および冷凍機で発生する熱の一部を車両用空調装置の暖房運転に利用する暖房アシスト運転を含む。制御装置は、暖房アシスト運転を実行する場合、冷凍運転を実行する場合に比較して、コンプレッサの回転数を低下させるとともに、コンデンサファンの回転数を低下させる。【選択図】図1
