Ammonia heat exchanger unit and system

摘要

A heat exchange unit for a heat exchanger system includes a heat exchange tube. The heat exchange tube including a heat exchange tube inlet and one or more heat exchange fins coupled along the heat exchange tube. The heat exchange tube extends from the heat exchange tube inlet to a refrigerant return. A heat exchange jacket is interposed between the heat exchange tube and a unit housing. The heat exchange jacket includes a jacket passage in communication with the refrigerant return. A first product passage extends from the product inlet to a product return. The heat exchange fins turbulate agricultural product in the first product passage while heat is transferred from the agricultural product to refrigerant in one or more of the heat exchange tube or the heat exchange jacket. Heat is transferred from the agricultural product to the refrigerant through the heat exchange jacket in the second product passage.
