More Information
Summary:Disclosed is a freezing protection system of a heat exchanger capable of preventing freezing of a heat exchanger. The system includes a discharge valve for opening and closing a discharge pipe of a fluid inside a heat exchanger; a freezing factor detection unit for detecting a freezing factor such that the discharge pipe is open, under an automatic control of the discharge valve, upon detection of the freezing factor when the heat exchanger is in a standstill state; and a discharge completion detection unit for detecting whether the fluid inside the heat exchanger has been completely discharge or not, such that the open discharge valve is closed under an automatic control of the discharge valve after the fluid inside the heat exchanger has been completely discharged.
