Description
技术领域 technical field
本发明涉及金枪鱼渔船余热吸收制冷系统，属于船舶制冷技术领域。 The invention relates to a waste heat absorption refrigeration system of a tuna fishing boat, and belongs to the technical field of ship refrigeration.
背景技术 Background technique
由于我国近海渔业资源的急剧衰退以及与周边国家渔业协定的正式签署并实施，我国海洋渔业的作业空间越来与小，我国渔业经济除了发展近海养殖外，还必须参与发展远洋捕捞，金枪鱼是发展远洋捕捞的首选鱼种，但是金枪鱼的特殊品质要求金枪鱼贮藏、加工必须保证-50℃至-60℃的低温环境。而冷凝温度却在40℃，为此现在金枪渔船配备有单机双级压缩机。目前金枪鱼远洋渔业作业船用低温冷藏、冷冻制冷系统一般采用活塞式单机双级机组，采用R22作制冷剂。制冷装置采用R22作制冷剂，系统运行效率不高；远洋渔船为冷库稳定运行，专门配有柴油发电机组，其排气及气缸冷却余热很大；同时主机余热量也很大。气缸冷却水80~90℃，该温度能量并没有有效利用，是一个急需解决的问题。 Due to the sharp decline of my country's offshore fishery resources and the official signing and implementation of fishery agreements with neighboring countries, the operating space of my country's marine fishery is getting smaller and smaller. In addition to the development of offshore aquaculture, my country's fishery economy must also participate in the development of deep-sea fishing. Tuna is the development The preferred fish species for ocean fishing, but the special quality of tuna requires that the storage and processing of tuna must ensure a low temperature environment of -50°C to -60°C. But the condensing temperature is at 40°C. For this reason, tuna fishing boats are now equipped with single-unit two-stage compressors. At present, the low-temperature refrigeration and freezing refrigeration systems for tuna ocean fishing vessels generally use piston-type single-unit two-stage units, and R22 is used as the refrigerant. The refrigeration device uses R22 as the refrigerant, and the operating efficiency of the system is not high. The ocean-going fishing vessel is equipped with a diesel generator set for the stable operation of the cold storage. The waste heat of the exhaust and cylinder cooling is large; at the same time, the waste heat of the main engine is also large. The cooling water of the cylinder is 80~90℃, and the energy at this temperature has not been effectively utilized, which is an urgent problem to be solved.
