Constant-temperature gas water heater with remote temperature regulation and cold water heat compensation control functions

The invention discloses a constant-temperature gas water heater with remote temperature regulation and cold water heat compensation control functions. The constant-temperature gas water heater comprises a cold water inlet and two hot water outlets. The temperature of hot water at the outlets of the constant-temperature gas water heater is remotely regulated through the method that the relative values of two routes of hot water flow are controlled through a water valve; and when the specific value of the outlet hot water flow of the first hot water outlet to the inlet cold water flow of the cold water inlet is increased, the temperature of hot water at the outlets rises, and otherwise the temperature of hot water at the outlets drops. The temperature of the constant-temperature gas water heater is controlled through an algorithm combining PID with the temperature of cold water at the inlet and flow feed-forward compensation, the interference of changes of the temperature and flow of cold water at the inlet to the temperature of hot water at the outlets of the constant-temperature gas water heater is reduced, and the control precision is improved. According to the method, no wired or wireless remote controllers are needed, the temperature of hot water of the constant-temperature gas water heater can be remotely regulated, and the control result is stable and reliable.
