HVAC approach for HVDC application.
A high-voltage, direct current (HVDC) electric power transmission system uses direct current (DC) for the bulk transmission of electrical power
- HVDC (high voltage DC supply) is mainly used for long distances to minimise power loss.
- The converter/rectifier hall is 1 big faradays cage designed hall with no entry to personnel during normal operations.
- All indoor M&E equipment must be grounded.
- Only ventilation is required except for high temp regions like the gulf.
- N+2 configuration for redundancy.
- AHU sections. Heating coil, humidifier, pre-filter + bag filter.
- 100 % fresh air with 30 Pascals pressurisation and with gravity release dampers at upper levels of the converter hall.
- Interior design Maximum 48 C minimum 5 C, maximum supply temp. 40c and minimum at 10c, maximum Relative humidity 60% and minimum 30%
- Heat losses on Average 300 KW, including Process piping.
- 500 Lux uniform Lighting.
- For security, entrance doors are interlocked for power shutdown in case of fire.
- Fire fighting, manual extinguishers at entry and automatic interior extinguishing on the interior for the controls room.
- BMS, all sensors High Temp & Low temp, high & low humidity etc... to connect to Controls room.
- I can be consulted on this and help you achieve your goals Remotely.
