HVAC SYSTEM ON A DECK OF FPSO HAVING REMOTE I/O DEVICE

摘要

PURPOSE: A Heating Ventilation Air Conditioning system on a deck of a Floating Production Storage and Offloading having a remote I/O device is provided to simplify a process related work of each block by minimizing the interface of each deck. CONSTITUTION: An HVAC system on a deck of an FPSO having a remote I/O device comprises a main HVAC control panel(10), multiple I/O units(40a,40b,40c), and limit switches(30a,30b,30c). The main HVAC control panel controls the HVAC system depending on the state of HVAC equipment. The remote I/O units receive state signals from the HVAC equipment located at decks and transmits the state signals to the main HVAC control panel. The limit switches output open/close state signals of the HVAC equipment, heater temperature high signals, and damper close signals for determining internal and external pressure.
