How does a rawal valve or hot gas bypass work?

June 3, 2014

In some cases, it benefits the system to incorporate some means of false-loading on the compressors.  Both Rawal valves and Hot Gas Bypass provide a solution for this.  In both cases, we're able to trick the compressor into staying on-line even if we do not have the load in the space.  This keeps your coil energized leading to increased comfort control.  However, keep in mind that keeping the compressor on means increased energy consumption.  Check out the video that Rawal put together which gives an overview of the technology.  Let your NE Applied Products sales engineer know if you have any questions.
