High-velocity cooling coils can carry condensate into downstream ducts, filters and equipment. This guide explains how to select moisture eliminators using coil face velocity, droplet-removal efficiency, pressure drop, drainage capacity, materials and maintenance requirements. It also includes calculation methods, a worked example and practical commissioning checks.

Learn how Pressure-Independent Control Valves (PICVs) improve hydronic system stability by maintaining design flow despite changing differential pressure. This guide covers PICV sizing, minimum ΔP, actuator selection, pump-head considerations, commissioning, common mistakes, and practical HVAC applications.

Calculating cooling load is essential for designing efficient HVAC systems in commercial buildings. It determines the amount of heat that must be removed to maintain comfortable indoor conditions. By analyzing factors like building envelope, occupants, lighting, equipment, and ventilation, engineers can accurately size air-conditioning systems and improve energy efficiency.
