Title:
GAS WATER HEATING SYSTEM AND CONTROL METHOD FOR GAS WATER HEATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/114806
Kind Code:
A1
Abstract:
The present application relates to a gas water heating system and a control method for the gas water heating system. The gas water heating system comprises: a combustion device; a main heat exchange device arranged on one side of the combustion device, wherein the main heat exchange device comprises an inner side flow channel and an outer side flow channel, and the distance between the inner side flow channel and the combustion device is greater than that between the outer side flow channel and the combustion device; a main liquid output pipe connected to the liquid output end of the inner side flow channel and the liquid output end of the outer side flow channel by means of pipelines; and a main liquid return pipe and an adjusting device, wherein the main liquid return pipe is connected to the liquid intake end of the inner side flow channel and the liquid intake end of the outer side flow channel by means of the adjusting device, and the adjusting device is used for adjusting the liquid intake amount of the inner side flow channel and the liquid intake amount of the outer side flow channel. According to the gas water heating system, the adjusting device adjusts the liquid intake amount of the inner side flow channel and the liquid intake amount of the outer side flow channel according to different working states of the gas water heating system, such that while the heat efficiency of the gas water heating system is improved, the temperature difference between the inner side flow channel and the outer side flow channel is also used for preventing smoke generated by the combustion device from condensing.
