The invention discloses a water heater system control method and device and a water heater system. The water heater system comprises at least two water heaters, all the water heaters are connected toone end of a water flow pipeline in parallel, and the other end of the water flow pipeline is connected to a water tank and a coil pipe in the water tank. The method comprises the steps that in response to a first water heating instruction, the water flow pipeline is controlled to communicate with the water tank, and all the water heaters are started; and when the switching condition is met, the water flow pipeline is controlled to communicate with the coil pipe, and operation of the water heaters is controlled according to the difference value between the actual temperature of the water tankand the set temperature. According to the method, the coil pipe is switched for heat exchange after the switching condition is met in the rapid water heating mode, so that the actual temperature in the water tank is gradually and slowly close to the set temperature, the temperature change of the water tank is stable, temperature overflow is prevented, the rapid water heating requirement of a useris met, meanwhile large-range fluctuation of unit loads can be avoided, and the unit operation stability is guaranteed.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater system control method and device, and the water heater system. Background technique [0002] At present, the multifunctional water heaters on the market are generally multifunctional water heaters with small cooling capacity, such as water tanks with a capacity of 100L, 200L, etc. The multifunctional water heaters with small cooling capacity can be flexibly configured in suitable places due to their small cooling capacity. In the specific space, one machine, one use, the water system is relatively independent, and the configuration mode can be flexibly configured. However, multifunctional hot water machines with large cooling capacity (such as water tanks with a capacity of 500L or 1000L, etc.) need to consider the situation of one machine with multiple functions or multiple modules in combination. The water system will become relatively complicated, and the ...
