Overview of Shanghai Bilang constant temperature water heater.
The constant temperature water heater refers to a water heater that can maintain a substantially constant outlet temperature set by the user when the inlet water flow rate, inlet water temperature, and gas pressure change.
From the daily use function to identify, the real constant temperature water heater in the household's multi-channel water supply system, no matter how the water flow and water pressure change, its outlet temperature is consistent with the set temperature.
water heater
Electric water heaters are divided into thermal heating, instant heating and water storage. Among them, the instantaneous heating type and storage type electric water heaters are still adjusting the ratio of cold and hot water through the mixing valve to adjust to their own bath temperature. The instant electric water heater does not mix cold water. The principle of achieving constant temperature is: the water heater has a built-in stepper motor to test the water flow of the inlet pipe, and it is converted into an electrical signal and input to the mainboard processor. The result will also be input into the motherboard processor. After the processor calculates, the heating tube will be controlled according to the result, and the heating power will be adjusted to achieve a constant outlet temperature.
Gas water heater
The current constant temperature gas water heater adopts the proportional valve type temperature control principle. There is a flow sensor in the pipeline of this water heater. The gas valve is an electric regulating valve (ie proportional valve).
The flow sensor converts the water flow into a corresponding electrical signal and inputs this signal into the controller. The controller adjusts the opening of the gas valve according to the strength or frequency of the input signal, so that the gas flow and the water flow change in direct proportion to achieve the purpose of constant water temperature.
When the water heater is working, the flow sensor can sense the size of the water flow and pressure, and transmit the signal to the proportional valve, who can control the fire discharge, and then control the fire power and adjust the water temperature.
