Back to the Basics

This Geo-exchange repair was necessary to get the client up and running. The system was 8 years old, with a history of failed compressors, nuisance trips and high energy consumption. It had 5 commercial 3 phase heat pumps distributed around a 2 acre facility. We were called to solve the problem and get the system performing as it should.

The Problem;

  • Poor mechanical design put radiant zones in series with heat pumps causing flowrates well outside of design range
  • Poor system control had the heat pumps short cycling, running hotter than necessary and using backup heat

The solution;

  • Re-evaluate and determine design parameters for mechanical equipment and hydronic delivery
  • De couple heating and heat pump loops, ensure design flowrate criteria are met
  • Install intelligent control system that is capable of staging, setback, and interlocking with other equipment
  • Install variable speed pressure controlled circulators for minimum energy consumption an maximum performance
