EMERGENCY GENERATOR ROOM TEMPERATURE CONTROL SYSTEM IN FLOATING OFFSHORE PLANT

摘要

The present invention relates to a system for controlling a temperature of an emergency generator room in a floating offshore plant which produces, stores, and handles liquefied natural gas (LNG). More specifically, the system for controlling a temperature of an emergency generator room in a floating offshore plant, comprises: a temperature sensor which detects an indoor temperature of an emergency generator room; a controller which outputs a control signal for controlling a temperature of the emergency generator room depending on the indoor temperature detected by the temperature sensor; a power switchover part which connects a power source from the emergency generator room to a cooling fan and a pump in accordance with the control signal applied from the controller; the cooling fan driven by receiving the power source through the power switchover part to flow indoor air into a heat exchanger; the heat exchanger which is autonomously equipped with a water circulation pipe and a cooling pin, and cools the indoor air that flows from the cooling fan by water supplied from a water tank; and a pump driven by receiving the power source through the power switchover part to pressurize water circulated between the water tank and the heat exchanger. According to the present invention, a temperature of air inside the emergency generator room is maintained at an appropriate level without inflow of air outside the emergency generator room in a state that explosive gas is leaked outside the emergency generator room, and without using any separate emergency power sources, thereby preventing explosion accidents inside the emergency generator room caused by inflow of external explosive gas, and efficiently controlling a temperature inside the emergency generator room without using emergency power sources even in a poor atmospheric environment where explosive gas is leaked outside the emergency generator room.
