About this course

In other courses we talk a lot about hydronic heating. This course is about using chilled water to provide cooling - you'll learn how these systems work, situations to avoid, and get into the details of some example systems.

This is course is part of our "Heat Pump System Design & Installation" series. You can take an individual course or enroll in the full program, which was created to provide a complete understanding of the design and installation of heat pumps systems.

  • Psychometrics of chilled-water cooling (13:34 minutes)
Module 6 • 1 assignments
Example systems

This modules assembles concepts and details from the previous modules into complete systems that provide chilled water cooling, as well as space heating and in some cases domestic water heating.

  • Example systems (34:22 minutes)
Module 7 • 1 assignments
Water loop heat pump systems

This module covers the fundamentals of water loop heat pumps systems used in commercial buildings.

  • Water loop heat pump systems (17:21 minutes)
Module 8 • 1 assignments
Systems that separate sensible & latent cooling
