Abstract

The invention discloses a gas water heater and a control method thereof. The control method includes: acquiring data of water flow rate, outflow water temperature and combustion heat of the gas waterheater to work out inflow water temperature; calculating required heat according to the inflow water temperature; adjusting current of a proportional valve according to the required heat to control the gas water heater to discharge water at a constant set outflow temperature. According to conservation of energy, the inflow water temperature is derived by adoption of an integral calculation method,and accordingly the problem of failure in simultaneous calculation of inflow water temperature under simple conditions and complex flow fluctuation conditions in the prior art is solved. In addition,a current value of the proportional valve can be accurately and quickly calculated according to the inflow water temperature, so that quickness in constant-temperature water discharging is realized.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a gas water heater capable of rapidly adjusting water temperature. Background technique [0002] The current gas water heater performs constant temperature control according to fixed parameters. Due to device differences, environmental differences and other reasons, constant temperature control is performed. When using feedforward control, the required control value is often not quickly and accurately given, resulting in the time required to reach the set temperature. longer. [0003] The invention patent with application number 201410519713.9 provides a water temperature control device for a gas water heater, including: an ambient temperature detection unit for detecting the ambient temperature; an inlet water temperature detection unit for detecting the inlet water temperature of the gas water heater; The outlet water flow detection unit is used to detect the outlet water flow of ...
