® WorleyParsons <br /> resources&energy <br /> 3.7 Compressed Gas Systems <br /> All compressed gas tanks/cylinders and pressure regulators required to operate and <br /> maintain the facility will be provided. All interconnecting piping, valves, <br /> instrumentation and controls will be part of design. <br /> 3.7.1 Carbon Dioxide <br /> A carbon dioxide system will be provided for fire protection at the CTG and STG. <br /> 3.8 Heating, Ventilating, and Air-Conditioning System <br /> The design basis for sizing the system will be as follows: <br /> Design Basis <br /> Area Summer Winter <br /> Control Room,Electronics Room,and 75°F,50%R.H. 70°F <br /> Office and Lab Areas <br /> Battery Room 80°F,50%R.H. 75°F <br /> CEM Bldgs 80°F,50%R.H. 60°F <br /> Electrical and Control Equipment Rooms, 80°F,50%R.H. 50°F <br /> All other Areas(incl.Turbine building) 100°F(Ventilated) 50°F <br /> The HVAC system will consist of building heating, building ventilation for fresh air <br /> makeup and cooling, and air-conditioning as required and will include: <br /> Two 100-percent-capacity HVAC systems for the control and electronics rooms and one <br /> 100-percent-capacity HVAC system for the balance of the administration building, with <br /> miscellaneous piping, ductwork, insulation, dampers, louvers, and controls for an <br /> efficient and operable system. Systems will not take suction from areas where fumes <br /> might be present (e.g., maintenance shop area) to prevent introduction of irritants and <br /> gases such as CO, into administration areas. <br /> • One 100-percent-capacity HVAC unit for the water treatment lab (may be part of <br /> other adjacent systems if not remotely located). <br /> • Separate redundant exhaust fans for battery room. <br /> • One 100-percent-capacity HVAC unit for the electrical switchgear room, control <br /> equipment room, and battery room sections of the water treatment building. <br /> • Ventilation fans and electric or gas radiant heaters for maintenance, warehouse, and <br /> water treatment areas. <br /> Lodi Energy Center 3.3 - 11 LEC AFC <br /> 071508 Rev.A <br />
