In our last article on hot gas reheat coils, we looked at the basic function of hot gas reheat coils and some common methods used to integrate them into a system. In this article, we'll look at some best practices when running hot gas reheat coil selections within Enterprise, SRC's coil selection software. For this exercise, we used a theoretical hot gas reheat coil to explain the coil selection process for hot gas reheat coils using the hot gas and parallel condensing methods.

Because of its rarity and the likelihood that the performance requirement can be met using one of the other configurations, we have not included selection best practices for the warm liquid method. But, if you find yourself working on an application that may be well suited for that approach, feel free to contact us directly and we’d be happy to take a look.

In the world of commercial HVAC, efficiency is a critical measurement of a unit’s effectiveness, and one (of many) methods used to improve that metric is with a hot gas reheat coil. In this article, we’ll explain the function of a hot gas reheat coil and examine the various methods used to integrate them into a unit:

• Hot gas method
• Parallel condensing method
• Warm liquid method
  
  

This is the first in a series of articles about battery power and its adjacent industries and processes. Check out our other post, "Application Spotlight: Solvent Recovery and Battery Liners."

Today, energy comes from a wide range of sources. The share of that collective power that comes from renewable energy sources continues to grow. In fact, in 2019, it was estimated that just under 20% of electricity generated at utility-scale electricity generation facilities in the United States was from renewable energy sources.[1]

Hydronics systems? Football? While you may not hear those terms in the same breath every day, there’s actually a mind-blowing amount of design and engineering that help keep football field surfaces playable through the cold winter months.

First, some context

With this year’s big game being played in Tampa Bay, frozen ground won’t play a factor, but January's NFC championship game took place at the site of probably the most famous instance of frozen turf in history - historic Lambeau Field.

For low-temperature hydronic systems, systems in which chillers and AHUs are located outdoors, or other equipment used in low-temperature processes, some form of glycol is a critical ingredient. It works to lower the fluid’s freezing temperature, enabling lower-temperature operation and preventing freezing.
