Abstract

The invention relates to an anti-freezing method, an anti-freezing control system and a gas water heater. The anti-freezing method comprises the following steps: obtaining a first detection temperature value on a pipeline of a heat exchanger, and obtaining a second detection temperature value of an environment in which the gas water heater is located; determining whether to enter an anti-freezingworking mode or keeping a standby working mode according to the first detection temperature value; and if it is determined to enter the anti-freezing working mode, determining to enter a first anti-freezing working mode, a second anti-freezing working mode or a third anti-freezing working mode according to the second detection temperature value. According to the anti-freezing method, a proper anti-freezing working mode is determined according to the second detection temperature value of the environment in which the gas water heater is located, anti-freezing gradation is distinct, pipeline icing frost cracks of the gas water heater can be effectively prevented, anti-freezing efficiency is relatively high, and energy waste can be avoided.

Description

technical field [0001] The invention relates to a water heater, in particular to an antifreeze method, an antifreeze control system and a gas water heater. Background technique [0002] In the northern region, the outdoor temperature is low in winter. Since the smoke pipe of the forced exhaust gas water heater leads to the outside, the cold air easily enters the inside of the forced exhaust gas water heater through the smoke pipe to exchange heat with the water in the pipeline. When the water temperature is lower than 0°C, there is a risk of freezing and cracking the pipeline. Among the existing antifreeze measures for gas water heaters, either only antifreeze joints are used for antifreeze, or only electric heating is used for antifreeze, or only combustion antifreeze is used, or only a combination of the two is used. However, when the external conditions are relatively harsh, such as when there is strong wind and the ambient temperature is very low, the gas water heater w...
