回收渔船用柴油主机排气余热的动力涡轮压缩制冷装置
摘要：
本发明公开了回收渔船用柴油主机排气余热的动力涡轮压缩制冷装置，它涉及压缩制冷技术领域。它的柴油主机一端连接中冷器，另一端连接主机后排气管，主机后排气管连有涡轮增压器，涡轮增压器也与中冷器连接，涡轮增压器连接进气管，涡轮增压器与控制阀二相连，控制阀二连有动力涡轮压缩制冷系统，动力涡轮压缩制冷系统连有热交换器，控制阀一与涡轮增压器并联设置，控制阀三与动力涡轮压缩制冷系统并联设置。本发明有益效果为：它能够将柴油机的排气余热充分利用，有效回收柴油主机废气能量，在不影响主机功率的情况下，额外输出制冷功率，柴油主机涡轮增压系统与动力涡轮压缩制冷系统联合运行后，可提高发动机有效效率，可提高燃油利用率。
摘要（英）：

The invention discloses a power turbine compression refrigeration device for recycling waste heat of exhaust gas of a diesel main engine for a fishing boat and relates to the technical field of compression refrigeration. One end of the diesel main engine of the power turbine compression refrigeration device is connected with an intercooler, and the other end of the diesel main engine is connected with a main engine rear exhaust pipe. The main engine rear exhaust pipe is connected with a turbocharger which is also connected with the intercooler. The turbocharger is connected with a gas intake pipe and a control valve II. The control valve II is connected with a power turbine compression refrigeration system which is connected with a heat exchanger. A control valve I and the turbocharger are arranged in parallel. A control valve III and the power turbine compression refrigeration system are arranged in parallel. The power turbine compression refrigeration device has the beneficial effects that the waste heat of the exhaust gas of the diesel engine can be fully used, energy of the waste gas of the diesel main engine is effectively recycled, and extra refrigeration power is output under the condition that the power of the main engine is not influenced; and after a diesel main engine turbocharger system and the power turbine compression refrigeration system operate in a combined mode, the effective efficiency of the engine can be improved, and the fuel utilization rate can be increased.
