Abstract

The invention discloses a gas water heater and a control method thereof, and the gas water heater is provided with a gas inlet, a water inlet and a water outlet and comprises a combustion system, a circulating water path, a working water path and a second heat exchanger, and the combustion system is communicated with the gas inlet. A circulating pump, a first heat exchanger and a buffer tank are arranged on the circulating water path, and heat exchange between the circulating water path and the combustion system is achieved through the heat exchange device. The working water path is respectively communicated with the water inlet and the water outlet. The second heat exchanger is connected with the circulating water path and the working water path so as to achieve heat exchange between the circulating water path and the working water path. The gas water heater is high in energy utilization rate, long in service life and high in comfort and safety.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a gas water heater and a control method for the gas water heater. Background technique [0002] The combustion method adopted by the gas water heater is mainly flaming combustion, that is, the gas and air are not pre-mixed in the combustion device, but are sent to the combustion chamber separately and burned while mixing in it. The flame is longer and has a sharp outline. Flame combustion belongs to diffusion combustion. Due to its high activation energy, slow combustion speed and incomplete combustion, the thermal efficiency decreases. In addition, the gas radiation of the flaming combustion flame is small, the main heat transfer method is convective heat transfer, and the energy utilization rate is low. In the flaming combustion mode, due to the difference in the contact between different parts of the combustion and the air, the completeness and temperature of the c...
