An Overdue Central Plant HVAC Upgrade
Star Service was tasked with upgrading the central plant HVAC system at a training facility in Houston, Texas. The HVAC mechanical equipment was extended beyond its serviceable life and the customer was continuously performing repairs to the boilers and pumps. The chillers had also failed and a temporary unit had been put in place. Control valves were failing and the existing Building Automation Systems (BAS) was basically non-effective.
Challenges
- Unreliable and Inefficient Air Conditioning
- Frequent Equipment Failures
- High Energy Costs
Solutions
- Demolish Old Systems
- New Open-Protocol BAS
- Install New Chillers, Pumps and Piping
- (2) Trane 130 Ton Air-Cooled Chillers
- (2) Trane 90 Ton Air-Cooled Chillers
- (2) Trane 60 Ton Air-Cooled Chillers
Results
We were able to retrofit the major components of their HVAC system by replacing the heating boilers, the pumps (CHW & HW), upgrade the pump VFDs. Two new chillers sized to replace the three failed chillers were installed. Work with a structural company, a new roof-mounted chiller pad was installed due to roof condition and weight concerns. Control valves at all AHUs were replaced. And to fully satisfy our customer’s concerns, a new open-protocol, BAS control system was installed.
