Problems solved by technology
[0002] At present, when the temperature in winter is below 0°C, the existing commercial air-energy water heaters and modular machines have the risk of freezing and cracking of the water system heat exchanger caused by sudden power failure, because no specialized personnel will notice when the power is cut off. Drain the water in the water system, causing the water to freeze in the heat exchanger and expand the heat exchanger

The invention discloses a water heater, a water circuit system anti-freezing control method and an anti-freezing controller of the water heater, and a storage medium. A water circuit system comprisesa water circuit heat exchanger, a circulation water inlet channel, a circulation water outlet channel, a drain channel and an exhaust channel. The anti-freezing control method comprises the steps thatwhen it is detected that the environment temperature is lower than the preset temperature, the water heater is controlled to be in the anti-freezing mode; and after the water heater is in the anti-freezing mode, and when it is detected that the water heater is power failure and the time of the water heater in power failure reaches the first set duration, the circulation water inlet channel and the circulation water outlet channel are controlled to be closed, and the drain channel and the exhaust channel are controlled to be opened so as to drain out the water in the water circuit heat exchanger. The anti-freezing control method achieves the function that at a low air temperature, when a unit is suddenly powered off, a program can control a valve to automatically drain out the water in thesystem so as to prevent the heat exchanger from cracking due to freezing, and further has the function of avoiding that the unit empties the system because of transient outage, and the function of automatically feeding water into the unit after the unit is powered on and starting up for operation.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to an antifreeze control method for a waterway system, a water heater, an antifreeze controller for the waterway system, and a computer storage medium. Background technique [0002] At present, when the temperature in winter is below 0°C, the existing commercial air-energy water heaters and modular machines have the risk of freezing and cracking of the water system heat exchanger caused by sudden power failure, because no specialized personnel will notice when the power is cut off. Drain the water in the water system, causing the water to freeze in the heat exchanger and burst the heat exchanger. Contents of the invention [0003] In order to solve at least one of the above technical problems, an object of the present invention is to provide an antifreeze control method for a waterway system. [0004] Another object of the present invention is to provide a water heater. ...
