Abstract

The invention discloses a constant temperature control system for a gas water heater, the system comprises a controller, a proportional valve assembly, a water flow detection assembly, a water inlet temperature detection assembly which are internally arranged in the gas water heater as well as a low delay temperature sensor arranged on a water outlet pipe in a water heater; the controller, the proportional valve assembly, the water flow detection assembly, the water inlet temperature detection assembly and the low delay temperature sensor are respectively connected with the controller; the lowdelay temperature sensor is used for collecting the water outlet temperature of the current gas water heater, and the temperature information is sent to the controller; the controller adjusts the proportional valve assembly according to the collected water flow of the current gas water heater, the current water inlet temperature, and the current water outlet temperature. The structure can changethe original control system of the gas water heater from a high hysteresis control system to a low hysteresis control system, so the control algorithm requirement of the system is reduced effectively;and meanwhile, the purposes of adaptability range and constant temperature performance improvement are achieved.

Description

technical field

[0001] The invention belongs to the technical field of gas water heaters, and in particular relates to a constant temperature control system and a constant temperature control method of a gas water heater. Background technique

[0002] With the improvement of users' requirements for the quality of life, the use of gas water heaters in different areas and areas is increasing; but due to the calorific value components in different areas, the calorific value in different seasons in the same area, and even different gas in the same area There are many differences in gas calorific value in companies, and the working environment of water heaters is more complicated. For example, different altitudes will affect the combustion conditions of water heaters; these states are often unknown, and the simple control algorithm will lead to constant temperature due to changes in the model time. Poor performance, especially when the gas pressure is low, leads to deterioration ...
