BlueBox process cooling
The BlueBox split systems cool inverters, servers and control equipment. This equipment sits in enclosed rooms and gives off a lot of heat. Without constant cooling the temperature rises quickly and the equipment shuts down to protect itself.
Before handover we pressure-tested the systems with dry nitrogen, pulled a vacuum and charged them. The nitrogen test finds leaks before any refrigerant goes in, and the vacuum removes air and moisture that would harm the compressor. After start-up we checked the control logic.
Main air conditioning plant
We calibrated the central plant with Bitzer compressors, set the superheat and ran performance tests under full heat load.
Correct superheat keeps liquid refrigerant out of the compressors and makes full use of the evaporator. The full-load test shows whether the plant holds the set temperature when the heat load is at its highest.
Controls and tests at sea
We also checked the unit controls and safety devices. The pressure switches stop a compressor when the pressure leaves the safe range, and phase-loss protection keeps the motors from running on an incomplete supply.
Equipment on the platform works in salty, humid air, and every further service visit needs transport out to sea and good weather. That is why the job finished with operational tests at sea, under real working conditions.
