The invention discloses a ventilation energy-saving system for a refrigerated cargo hold of an ammonia-powered container ship. The ventilation energy-saving system is composed of a temperature monitoring system, an air pre-cooling system, a ventilation pipeline system and a central control system. The temperature monitoring system is composed of a temperature sensing probe arranged at the end of a heat dissipation opening of the refrigerating box and is mainly responsible for monitoring temperature information near the heat dissipation opening of the container in real time. The air pre-cooling system is responsible for cooling normal-temperature air into low-temperature air through a heat exchanger; the ventilation pipeline system feeds the cooled low-temperature air into the specific position where the cold box is located in the refrigerated cargo hold; and the central control system is responsible for simulating and calculating temperature field distribution in the refrigerated cargo hold and the number and position of the cold boxes according to the received temperature monitoring data, and formulating and sending specific instructions for controlling the opening and closing of each air outlet, the air blowing amount and the rotating speed power of a ventilation fan. The heat exchange process that ammonia fuel absorbs energy in the gasification process is reasonably utilized, the ventilation air pipe form is optimized, and the optimal cooling effect of the refrigerated cargo hold is achieved.

    本发明公开了一种氨动力集装箱船冷藏货舱的通风节能系统,由温度监控系统、空气预冷系统、通风管路系统及中央控制系统组成;温度监控系统由布置冷藏箱散热口端部的温度感应探头组成,主要负责实时监控集装箱散热口附近的温度信息;空气预冷系统负责将常温空气通过热交换器冷却为低温空气;通风管路系统将冷却后的低温空气送入冷藏货舱内具体冷箱所在位置;中央控制系统负责根据收到的温度监控数据,模拟计算出冷藏货舱内温度场分布、冷箱数量位置,制定并发送具体指令:控制各出风口的开启、关闭、吹风量大小,以及通风风机转速功率。本发明合理利用氨燃料在气化过程中吸收能量的热交换过程,优化了通风风管形式,实现了最佳冷藏货舱的降温效果。
