Hot gas bypass is a process used in industrial and commercial HVAC systems to manage temperature levels and energy efficiency. It involves diverting warm air outdoors, often using a damper or bypass system, to prevent the air conditioner from having to work too hard — thus saving both energy and money. Bypassing hot gas is an efficient way of keeping temperatures comfortable without putting extra strain on the system or exceeding the necessary maximum temperature set point. Hot gas bypass gives optimal environmental conditions, as well as helping maintain control over energy bills.
