Problems solved by technology

[0003] However, when the zero-cold water gas water heater is actually used, the water stored in the circulation pipeline has heat loss, the temperature of the return water rises slowly, and the preheating time is long
And the longer the circulation pipeline, the greater the heat loss, the longer the user waits for hot water, and the user experience is not good

Abstract

The invention discloses a preheating and heat preservation control method for a zero-cold water gas water heater. The control method includes the following steps: S1, the gas water heater is in a standby mode; S2, controlling the gas water heater to enter the preheating working mode; S3, recording the temperature of the return water when the pump is turned on T 开回 , and press the preset temperature T 预设 Compensation temperature difference ΔT 补偿 The sum controls the outlet water temperature T 出 ; S4, judge the measured backwater temperature T 回 Is it greater than the return water temperature T when the pump is turned on? 开回 and return water temperature rise ΔT 回升 , if so, restore the preset temperature T 预设 Control the outlet water temperature T 出 , if not, it is judged whether the condition of preheating and shutting down the pump is met. It makes up for the heat loss of the pipeline by increasing the preheating water temperature, so as to shorten the preheating time and improve the user experience.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a preheating and heat preservation control method for a zero-cold water gas water heater, which is suitable for domestic hot water supply gas water heaters or dual-purpose furnaces. Background technique [0002] In the related art, the zero-cold water gas water heater has become a trend in the gas water heater industry because it can realize the instant hot water. When the zero-cold water gas water heater starts the preheating function, the built-in circulating water pump runs to drive the external hot water pipe and the stored water in the return pipe to circulate and realize preheating. [0003] However, when the zero-cold water gas water heater is actually used, the stored water in the circulation pipeline has heat loss, the return water heats up slowly, and the preheating time is long. And the longer the circulation pipeline, the greater the heat loss, the longer the u...
