Situation is that target leaving water temperature is really less than or equal to hot water temperature, but due to the inspection of the first temperature sensor 114
Location is set, hot water in 110 different location of hot water flux there are reasons such as the temperature difference, in the initial phase that hot water individually exports, first
The hot water temperature that temperature sensor 114 detects is relatively low relative to accurate hot water temperature, and is held when hot water individually exports
After continuous a period of time, the hot water temperature that the first temperature sensor 114 detects can be infinitely close to accurate hot water temperature, target
Leaving water temperature can be less than or equal to hot water temperature, calculate the target of hot water or cold water needed for reaching target leaving water temperature at this time
Water ratio adjusts the actual amount of water ratio of hot water and cold water to target water ratio, so that practical leaving water temperature reaches target
Leaving water temperature meets the needs of users and is expected.
Second situation is that target leaving water temperature is strictly to be greater than hot water temperature, then continuing one when hot water individually exports
When section, the hot water temperature that the first temperature sensor 114 detects illustrates that the target of setting goes out still less than target leaving water temperature
Coolant-temperature gage is excessively high, and water supply device 100 can not provide temperature and meet user demand and desired water, prompts user's water temperature not at this time
Foot, the mode of prompt have very much, can be shown by touch screen, can also be alarmed by alarm.
If NO, i.e., target leaving water temperature is less than or equal to hot water temperature to the result of step S330, then directly executes
Step S350: the target water ratio of hot water and cold water needed for calculating reaches target leaving water temperature, adjusting hot water and cold water
Actual amount of water ratio is to target water ratio.
Further, Fig. 6 is please referred to, the target water ratio of hot water and cold water needed for reaching target leaving water temperature is calculated
Example, actual amount of water ratio to the step of target water ratio for adjusting hot water and cold water include:
Step S360: the target water and step S370 of hot water or cold water needed for reaching target leaving water temperature are calculated: adjusted
The actual amount of water of hot water and cold water is saved to respective target water.
Closer, the step of calculating the target water of hot water or cold water needed for reaching target leaving water temperature includes step
It is rapid:
According toAnd two formula of Q '=Q1+Q2 calculate the target water of hot water or cold water, wherein Q1 is heat
The target water of water, Q2 are the target water of cold water, and Q ' is water yield, and T is target leaving water temperature, and T1 is hot water temperature, and T2 is
Cold water temperature.
Specifically, formulaIt is released jointly by two formula of CM1 (T1-T)=CM2 (T-T2) and M=ρ Q,
