What are the graduations and max bypass of the hot gas bypass valve?
InRow Cooling Cause:
The hot gas bypass is controlled by and electronic stepper valve with 1596 steps. The unit capacity is modulated by both the valve and the evaporator fans, so the % open of the HGB valve will not always correspond to a fixed % of unit capacity reduction. If the evaporator fans were held at a constant speed, then the HGV open 100% results in the unit reduced to approximately 65%, valve open 50% results in approximately 70% capacity.
