+C*Mcold*tcold。
User setting bathing time Twash and bathing temperature twash, water heater can detect the temperature tcold into cold water
With water flow vflow at spray head when bathing；C is the specific heat capacity of water, is constant 4.2 × 103J/ (kg DEG C), Mwash are users
The gross mass of bathing water, the stream of water when the gross mass of user's bathing water can be had a bath by the time and user of user's bathing
The product of the density three of amount and water acquires, i.e. Twash*vflow* ρ, twash are bathing temperature, and being previously noted is user oneself
Be arranged, Mx is the quality of hot water in liner, and be for the volume Vtank of a water heater liner it is certain, by water heater
Model determines, before data factory in built-in water heater, so in liner hot water quality can by the volume of liner and
The product of both the density of water acquires, i.e. Vtank* ρ, and Mcold is cold water quality during user has a bath, and is when user's bathing
Water in liner carries out bathing after water mixing valve and cold water mix to suitable temperature, and cold water quality can during user has a bath
It is acquired with the difference by both quality of water in the gross mass and liner of user's water, i.e. (Twash*vflow* ρ-Vtank*
ρ), tcold is water heater detection, and by C*Mwash*twash=C*Mx*tx+C*Mcold*tcold, C*Twash* can be obtained
Vflow* ρ * twash=C*Vtank* ρ * tx+C* (Twash*vflow* ρ-Vtank* ρ) * tcold.
In above formula only have liner in water temperature tx be it is unknown, tx=[Twash*vflow*twash-can be acquired
(Twash*vflow-Vtank) * tcold]/Vtank, ignores influence of the temperature to water density in the above process.
It is being discharged at spray head when user setting, water heater can directly detect the stream being discharged at spray head at this time
Amount, often sometimes user setting when spray head at be not discharged, can't detect water flow vflow at spray head at this time, this
