Understanding chilled water plant performance

摘要

The relatively high energy cost of cooling commercial buildings has long caused owners, operators and engineers to seek efficiency improvements leading to energy cost savings. Those improvements have progressed from new pumping strategies (variable-primary flow) to complex optimization techniques, all the way to the incorporation of machine learning algorithms.As the bar for performance continues to rise, heating, ventilation and air conditioning professionals will need to update their skill sets and even their vocabulary to keep pace with the latest advancements.Chilled water codes, standards For buildings taller than two stories in height and/or 25,000 square feet, energy codes typically allow for energy compliance via four different paths:1. ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings - Prescriptive.2. ASHRAE 90.1 - Performance.3. International Energy Conservation Code - Prescriptive.4. IECC - Performance.
