The invention relates to a system suitable for a central cooling frequency conversion systems of a polar ship. A seawater inlet of a seawater pump in the system is connected with a seawater pool, anda seawater outlet of the seawater pump is communicated with the seawater pool through one side of seawater of a plate type central cooler via a seawater side three-way temperature control valve to form a heat exchange loop; a fresh water outlet in the fresh water side of a plate-type central cooler is connected with a fresh water inlet pipe of cooled equipment through a fresh water side three-waytemperature control valve and a fresh water pump; a fresh water outlet pipe of the cooled equipment is communicated with a fresh water inlet in the fresh water side of the plate-type central cooler toform an auxiliary heat exchange loop, and the seawater pump is electrically connected with a seawater pump frequency converter; a fresh water temperature sensor is arranged on a connecting pipe between the fresh water side three-way temperature control valve and the fresh water pump; a signal input terminal of a control system is connected with a seawater temperature sensor and a fresh water temperature sensor, and the control signal output terminal is connected with a frequency converter, a fresh water pump, the temperature controller of the seawater pool, the fresh water side three-way temperature control valve and the seawater side three-way temperature control valve.

    本发明涉及一种适用于极地船舶的中央冷却变频系统,该系统中的海水泵的海水进水口连接海水池,海水出水口通过板式中央冷却器海水一侧经海水侧三通温控阀连通海水池形成热交换回路;板式中央冷却器淡水一侧的淡水出水口通过淡水侧三通温控阀、淡水泵连接被冷却设备的淡水进水管,被冷却设备的淡水出水管连通板式中央冷却器淡水侧的淡水进水口形成辅助热交换回路,海水泵电连接海水泵变频器,海水泵进水口还设有海水温度传感器;淡水侧三通温控阀与淡水泵之间的连接管上设有淡水温度传感器,控制系统信号输入端分别连接海水温度传感器和淡水温度传感器,控制信号输出端分别连接变频器、淡水泵、海水池的温度控制器、淡水侧三通温控阀以及海水侧三通温控阀。
