HVAC System Optimization

Bring air-side TAB readings, instrument records, tolerance checks and deficiencies into one reporting workflow with Nexora’s Excel workbook and 20-page pocket field handbook.

A practical guide to chilled-water pump-trip transients: screen rapid velocity changes, specify check-valve dynamics, check high and low pressures, and define a specialist surge study.

Size a stratified chilled-water tank against usable thermal energy, discharge power and temperature limits. Worked examples cover water volume, flow, low delta-T sensitivity and overnight charging.

Check whether cooling-tower water can meet the chilled-water requirement, how partial economizing shares the load, and when total plant electricity makes it worthwhile.

A practical glycol design workflow, with worked flow, resistance and capacity examples, to keep freeze protection, chiller selection and commissioning on the same basis.

Why a close temperature approach changes exchanger selection, and how to compare the thermal benefit with pressure drop, pumping energy and maintenance access.

Small temperature errors become large cooling-energy errors when ΔT is low. Check the sensor pair, flow installation and complete measurement chain before trusting totals.

A practical guide to remote DP sensors, branch pressure requirements and stable reset logic for variable-flow chilled-water pumps, with a worked pressure example.

A reliable staging sequence compares feasible plant combinations, protects evaporator flow and waits for stable evidence before switching. Start with measured load.

Warmer chilled water can reduce compressor work, but coils still need to cool and dehumidify. Set reset limits from air-side performance, flow and plant trends.

Size chilled-water buffer volume from minimum cooling output, low-load demand and permitted temperature swing, then verify active volume and manufacturer limits.

A cold coil does not guarantee a comfortable room. Learn how to distinguish AC equipment faults from duct-distribution problems—and how properly designed smart HVAC systems control airflow, capacity and comfort beyond a single thermostat.
