摘要： A freeze resistant method for draining liquid condensate from a condensate furnace includes quickly purging the liquid condensate from a condensate reservoir. A condensing heat exchanger connected to a condensing reservoir stores liquid condensate as the system is in use. An inducer produces a positive pressure along a condensate line to the outlet of the reservoir, creating a back pressure which prevents draining of the reservoir. When the inducer is shut off, the positive pressure is removed, and the liquid condensate rapidly flushes from the reservoir. The amount of liquid condensate remaining in the system and exposed to cold conditions can be minimized.
