The larger or more complex a cooling plant becomes, the more challenges to its ef-ficiency it will face. When applied wisely, modern controls and equipment can rise to meet those challenges. Read up on active balancing, pump dynamic differential setpoint control, and more responsive tactics for when the worst thing you can do is just go with the flow.
Consider these factors when sizing up a potential upgrade. In addition, pick up a few easy tips for maintenance in the meantime. You can’t necessarily buy time, but you can get in front of a worst-case breakdown scenario.
Sometimes it does pay to sweat the small stuff. Data availability might vary depending simply on where you’re accessing it. Not only selection but placement of your sensors and transmitters can influence their effectiveness and response time. Bearing down on such details on the BMS side can yield long-term results for your cooling goals.
The particular charms of panels, chilled beams, and related options seem to be at-tracting more attention from designers and owners these days. Design, installation, and even architectural considerations can earn a hard look at radiant for a surpris-ing number of applications.
Not exactly business as usual: a retrofit of a retrofit involving custom air handling boxes and the limitations of a historical building. The project team assessed the possible routes and mapped a course guided by VRF capabilities and precision work onsite.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
