Wall-hung boiler temperature control method, device, wall-hung boiler, and readable storage medium

Abstract

The invention discloses a temperature control method and device of a wall-hanging stove, the wall-hanging stove and a readable storage medium. The method includes the steps that the heating outlet water temperature value of the wall-hanging stove and the temperance difference value of the domestic hot water temperature value and preset domestic hot water temperature are acquired in a domestic hotwater outlet water temperature control mode; whether the heating outlet water temperature value is larger than a first threshold value or not is judged; the first threshold value is determined according to the high-temperature protection preset temperature value of the wall-hanging stove; when the heating outlet water temperature value is larger than the first threshold value, whether the temperature difference value is smaller than a first preset temperature difference or not is judged; and when the temperature difference value is smaller than the first preset temperature difference, the operational mode of the wall-hanging stove is controlled to be a heating outlet water temperature control mode. By adoption of the method, when the heating outlet water temperature value is larger than the first threshold value and the temperature difference value is smaller than the first preset temperature difference, the heating outlet water temperature control mode is adopted by the wall-hanging stove, the gas output quantity is reduced so that the heating outlet water temperature value can be decreasd, high-temperature protection halting cannot happen to the wall-hanging stove, and continuousoutputting of hot water is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wall-hung boilers, in particular to a temperature control method and device of a wall-hung boiler, a wall-hung boiler and a readable storage medium. Background technique [0002] Gas heating and hot water dual-purpose boilers are commonly known as wall-hung boilers. Common plate-exchange wall-hung boilers are prone to scaling on the domestic hot water side of plate-exchange when the water quality is poor and the hot water temperature is set above 50°C, resulting in poor plate-exchange heat transfer effect, and the final domestic hot water outlet temperature cannot reach the user’s level. Due to the high return water temperature, the final heating outlet temperature reaches the high temperature protection condition of the system, so that the user cannot continue to use hot water under the premise of scaling of the wall-hung boiler. [0003] In the prior art, the water quality of the domestic hot water inf...
