Hot gas bypassed to suction line Hot gas bypass can stabilize the system balance point by diverting hot, high-pressure refrigerant vapor from the discharge line directly to the low-pressure side of the system. This tactic. keeps the compressor more fully loaded while the evaporator satisfies the part-load condition.

What is the purpose of a hot bypass valve in a compressor? - Quora Bypass refrigerant hot gas to the evaporator (cooling coil) to add load to that side of the operation. This is useful for when the cooling load is too low to sustain cooling operation and cycling is to be avoided. It is a bit energy-wasteful but it prevents loss of all cooling for five or so minutes between cy.
