General Information

Hot Gas Bypass

The hot gas bypass (HGBP) control option is designed to minimize machine cycling by allowing the chiller to operate stably under minimum load conditions. In these situations, the inlet guide vanes are “locked” at a preset minimum position, and unit capacity is governed by the HGBP valve actuator. Control circuitry is designed to allow both the inlet guide vanes and the HGBP valve to close for unit shutdown.

After a chiller starts and is running the inlet guide vanes will pass through the HGBP Cut-In-Vane position as the chiller starts to load. As the chiller catches the load and starts to unload, the inlet guide vanes will close to the HGBP Cut-In Vane position. At this point the movement of the inlet guide vanes is frozen and further unloading of the chiller is controlled by the opening of the HGBP Valve 4M5 and module modulates the HGBP valve at low loads. When the control algorithm determines the chiller to be shut down, the inlet guide vanes will be driven fully closed, and the HGBP

valve will be driven closed. After the inlet guide vanes are fully closed the chiller will shut down in the Friendly mode. Chillers with HGBP have a discharge temperature sensor (4R16) monitoring the discharge gas temperature from the compressor. If this temperature exceeds 200°F, the chiller will shut off on a MAR diagnostic. The chiller will reset automatically when this temperature drops 50°F below the trip-point.

HGBP is enabled in the Features menu settings Group of the DV Menus by enabling the option. The setting the HGBP Cut-In Vane Position is setup at unit commissioning via the service tool.
