In the hot-gas bypass control method, which component is bypassed?

• A. An Expansion Valve
• B. The Condenser
• C. The Compressor
• D. The Evaporator

Answer: (B)

Hot-gas bypass control works by diverting the hot, high‑pressure discharge gas from the compressor away from the condenser. By routing the gas around the condenser, that component is effectively bypassed. This lets the system modulate cooling capacity and head pressure without changing refrigerant charge or compressor speed. The main cycle elements—the compressor, evaporator, and expansion device—remain in use, while the condenser path is the part being bypassed.
