Sizing an expansion tank for a chilled water system is not a guessing exercise. A small error in system volume, pressure range, or temperature assumption can cause relief discharge, unstable pressure, air ingress, and long-term maintenance issues. Proper calculation ensures reliable operation, protects equipment, and avoids costly design mistakes.

Designing chilled water systems for high-rise buildings requires more than just capacity sizing. From pressure zoning to pump optimization and energy efficiency, every detail impacts performance. This guide breaks down the key engineering principles to help you design reliable, efficient, and future-ready HVAC systems.

VRF and chilled water systems are two widely used HVAC solutions for large buildings. VRF systems offer flexible zoning, energy efficiency, and easier installation, making them suitable for offices and hotels. Chilled water systems, however, are ideal for very large facilities like airports and hospitals due to their scalability and ability to handle high cooling loads efficiently.
