Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
As it is shown in figure 1, present embodiments provide for the control method of a kind of water heater, above-mentioned Teat pump boiler
Including heat pump heating combined equipment 2 and electric heater unit 3.For the control method of water heater concrete include following step
Rapid:
Step S1: detection ambient temperature T1, then according to T1Determine switching temperature T；
Step S2: to the water temperature T in water tank2Detect, work as T2During≤T, use heat pump heating combined equipment 2
Water in water tank is heated, works as T2＞ T and when the most not up to arranging temperature, switches to electric heater unit 3
Water in water tank is heated until arranging temperature.
Owing to heat pump heating combined equipment 2 needs to absorb heat, therefore, heat in heating operations in outside air
Pump water heater is affected bigger in heating operations by ambient temperature.The situation that especially ambient temperature is relatively low
Under, use heat pump heating combined equipment 2 to heat in the low water temperature stage, now heat pump heating capacity decay is less,
Instantaneous COP coefficient is higher.But when hot water heating to a certain water temperature (switching temperature T), under this water temperature,
The instantaneous heating capacity of heat pump is decreased obviously, and instantaneous COP coefficient is the lowest, and energy-saving effect is the most inconspicuous.For this
Problem, when the water temperature in water tank reaches switching temperature T, water heater needs to switch to electric heater unit 3 and enters
Row heats, and by heat pump heating combined equipment 2 and the switching of electric heater unit 3, could improve heating of water heater
Efficiency, and there is preferable energy-saving effect.
It should be noted that above-mentioned switching temperature T is to draw through substantial amounts of test at different temperature
Numerical value, and different switching temperature T corresponding to ambient temperature also differs.
Concrete, ambient temperature T1The value of switching temperature T of numerical value its correspondence the least the least.
As worked as T1When >=0 DEG C, switching temperature T=65 DEG C；As worked as T1When=-1 DEG C, switching temperature T=60 DEG C；

Change temperature T, and by water temperature T2Compare with T-phase and then select to use heat pump heating combined equipment 2 to heat or electrical heating dress
Put 3 heating.
Concrete, after control device 1 receives ambient temperature T1 and water temperature T 2, first, according to
Ambient temperature T preset1With switching temperature T, determine ambient temperature T detected1Corresponding cuts
Change temperature T, after determining switching temperature T, by switching temperature T and water temperature T2Compare, work as T2≤T
Time, use heat pump heating combined equipment 2 that the water in water tank is heated, work as T2Water temperature during ＞ T and in water tank is also
When not up to temperature is set, switches to electric heater unit 3 and the water in water tank is heated until reaching heat pump
Water heater temperature is set.
