The invention relates to the field of air conditioning systems, in particular to a refrigerating system for a ship and the ship. The marine refrigerating system comprises a main refrigerating circulating pipeline and a seawater refrigerating pipeline; the seawater refrigeration pipeline comprises a heat exchanger, an additional refrigerant water pipeline and a seawater pipeline; the additional refrigerant water pipeline is communicated with a hot fluid loop of the heat exchanger, and the additional refrigerant water pipeline is connected to a main refrigerant water pipeline of the main refrigeration circulation pipeline in parallel, so that refrigerant water flowing back from a user side enters the heat exchanger; the seawater pipeline is communicated with a cold fluid loop of the heat exchanger, so that seawater and refrigerant water exchange heat at the heat exchanger, and then the refrigerant water is refrigerated. According to the refrigerating system for the ship provided by the invention, a set of refrigerant water and seawater heat exchange refrigerating system is additionally arranged on the basis of an existing refrigerating system, free low-temperature seawater resources can be fully utilized, the compressor is prevented from being in a low-load operation state for a long time, and the operation cost is reduced to a certain extent.

    本申请涉及空调系统领域,尤其是涉及一种船用制冷系统及船舶。船用制冷系统包括主制冷循环管路和海水制冷管路;所述海水制冷管路包括换热器、附加冷媒水管道和海水管道;所述附加冷媒水管道与所述换热器的热流体回路连通,且所述附加冷媒水管道并联至所述主制冷循环管路的主冷媒水管路上,以使用户端回流的冷媒水进入所述换热器;所述海水管道与所述换热器的冷流体回路连通,以使海水与冷媒水在所述换热器处换热,进而对冷媒水制冷。本申请提供的船用制冷系统,在现有的制冷系统上增加了一套冷媒水和海水换热的制冷系统,能够对免费的低温海水资源进行充分利用,避免压缩机长期处于低负荷运转状态,在一定程度上降低了运营成本。
