Hello all, question regarding adding hot gas bypass to a Copeland digital scroll. Unit has a low load in winter time and satisfactory load in summer. Problem is freeze protect alarms due to compressor starts at 100% capacity for a short time before it starts to unload. During this time LWT takes a nose dive and it's hit or miss if an alarm comes up. Once it starts to unload, it's fine.

There is a buffer tank.
Unit is configured for max unloading.

Thinking of adding HGB to be separate from the Carrier chiller controls to load evap during these times. But am wondering if that will create other problems?

This is a 10 ton air cooled chiller.

Thoughts and thanks!
