Cool water quantity X needed for mark temperature:
Increasing the cold water total Water X ' being blended into needed for applying after water number, really according to determine
When settled front increase-volume operates corresponding temperature S, employing equation below:
Wherein, X '=X+A,
In above-mentioned formula, target temperature T1 is the leaving water temperature that air-source water heater pre-sets,
Can obtain, for known quantity according to the leaving water temperature value that arranges of user；T2 is air-source water heater
The temperature of the water in water tank when not opening increase-volume, can be true according to the actual model of air-source water heater
Fixed, the most do not use electrically heated air-source water heater (not opening increase-volume), the heating temperature of water tank
Degree is 55 DEG C, and this parameter is also known quantity；T3 is the cold water temperature of air-source water heater cold water pipe
T3, can obtain cold water temperature angle value by increasing temperature sensor at cold water pipe, and this parameter is
The amount of knowing；The water capacity Y of air energy water heater water tank determines according to actual model, for known quantity；
According to above-mentioned T1, T2, T3 and Y, in conjunction with the formula of specific heat capacity, can calculate above-mentioned
X, it may be assumed that when not opening increase-volume operation the temperature of water in water tank convert to needed for target temperature cold
The water yield.Above-mentioned A can be empirically determined, such as, increases by people's water, can basis
Experience is learnt probably to be needed to increase the 60L water yield, and A can be with value 60.The value of A can be air
Fixed value can be rule of thumb set to by water heater producer, it is also possible to provide one and set when making
The interface put is configured according to experience to user, user.After determining X and A value,
May determine that X ', X '=X+A, then according to law of conservation of energy, determineX ', T1, T2, T3, Y are brought in above-mentioned formula, can be
Determine the heating-up temperature of this increase-volume eventually.
Preferably, the present invention can arrange multistage increase-volume at air-source water heater, different stage
Its design temperature of increase-volume is different, opens tackling the many people of different situations, such as family
One-level increase-volume, can meet and increase a personal use hot water, and not cause hot water to waste；Family is many
Two people then open two grades of increase-volumes, can meet and increase the use hot water demand of 2 people and do not make
Become hot water waste；Family is many, and three people then open three grades of increase-volumes, can meet and increase 3 people's
Use hot water demand.While meeting water demand, and do not cause hot water to waste, save yet
Electric power resource.
It is specifically described below in conjunction with example:
In order to meet above-mentioned use demand, its design temperature of the increase-volume of different stage should be how many
It it is a unknown number.
The people of increasing need to improve the computational methods that water temperature value is how many and see below more:
1) known conventional condition is: 40 DEG C is user's coolant-temperature gage (T1), and 55 DEG C is without increase-volume
Time water tank water temperature (T2), 25 DEG C is inlet water temperature (T3), the equal 40 DEG C of water temperatures of 60L people
Water consumption (A).
2) defined parameters: Y is water tank capacity, and Y=200L, X are for converting Y 55 DEG C of hot water of liter
To the water yield required when 40 DEG C；
S1 is the set temperature value of one-level increase-volume；
S2 is the set temperature value of two grades of increase-volumes；
S3 is the set temperature value of three grades of increase-volumes
…
Then: equation below can be formed according to ability conservation Q=mc Δ T:
First, time without increase-volume, water tank water temperature is 55 DEG C, then it follows that
C*55*Y+c*25X=c*40* (X+Y)
In formula:
C is that specific heat of water holds, and each Xiang Shizhong has, and can divide out；
X=Y can be drawn.That is: the cold water of exchange equivalent during water temperature 55 DEG C 25 DEG C can obtain
The warm water of 40 DEG C.
So when arranging one-level increase-volume, owing to water tank capacity Y will not change, so wanting to increase
Adding the water consumption of a people, X ' increases 60L, i.e. X '=X+60 than former X.
So can row equation again during one-level increase-volume:
S1*Y+25X '=40 (X '+Y)
Bringing X '=X+60 into, the most above-mentioned equation is: S1*Y+25 (X+60)=40 (X+60+Y)
Then S1=15X/Y+40+900/Y
Because X=Y, so S1=15+40+900/Y=55+900/Y.
When i.e. water tank capacity is 200L,
One-level increase-volume arranges temperature and is only required to be 55+900/200=59.5 DEG C.
S2=55+1800/Y=64 DEG C is equally drawn according to above-mentioned calculating, S3=68.5 DEG C ...
This is a relation waiting number to be incremented by.Then, accordingly when being configured, every one-level can be allowed to increase
Hold and exceed 5 DEG C of demands that can meet many personal use hot water than upper level design temperature.Specifically
Scheme shown in Figure 2.
In the embodiment of above-mentioned offer, the heating mode of air-source water heater arranges electric heating
Pattern, electric heating pattern is to be realized heating by Electric heating, its heating limit of machine self the most by compression
System, heating-up temperature can reach boiling point in theory.Air-source water heater is used to heat user
Cheng Zhong, when family guest people needs to increase the use of hot water, or occurs a large amount of in special circumstances
When hot water is concentrated use in, increase-volume scheme can be opened, heat to electrically, improve output
The hot water amount of target temperature, it is achieved the increase-volume of air-source water heater.Further, user can basis
The demand of actual used water amount selects concrete increase-volume amount, is detecting after user opens increase-volume operation,
Can be according to the concrete increase-volume mode of user's actual selection, the use analyzing user's needs of intelligence
