World Market Center
Construction of the 20-story Phase III began in 2007 and was completed in 2008. Trane secured the order for 1,198 Trane water-source heat pumps. Trane also brought to the table wireless zone sensors; a time-and money- saving improvement that helped World Market Center “cut the cord” with hard-wired sensors:
The 2,100,000 sq.ft. facility is entirely controlled via a Trane Tracer Summit control system. The control system is responsible for controlling:
- Eight Evapco cooling towers
- Six Armstrong cooling tower pumps
- Three 12,000 MBH Bryan boilers
- Three Armstrong variable speed hot water pumps
- Six Armstrong variable speed building pumps
- Four Tranter plate & frame heat exchangers
- Six Temtrol air handling units
- 1,198 Trane water-source heat pumps
- 1,198 Trane wireless zone sensors
Control Strategies
- Building water variable primary flow based on differential pressure
- Boiler add & subtract sequencing via Tracer Summit
- Heat exchanger add & subtract sequencing via Tracer Summit
- Cooling tower, boiler & pump rotation sequencing based on
- run-hours
- Heat pump loop control via Tracer Summit
