Floating Head Pressure Controls for Multiplex Systems

At a Glance

Status 
active
Fuel type 
electric
Sector 
commercial
Applications 
refrigeration
Sunset date 
Sep 30, 2022

This measure applies to refrigeration systems with multiple compressors in parallel. The RTF currently has a UES measure for single compressor systems, but due to the number of measure applications and site specific details for multiplex systems, this measure was developed as a standard protocol. 

Eligible systems are commercial refrigeration systems comprised of multiple compressors in parallel, discharging to a common condenser. The system cannon use heat recovery for HVAC, but can use it for water heating, and is not required by code. The most common application is groceries though the measure is not limited to only grocery applications.
