Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is made further
Describe in detail.Following example are used for illustrating this utility model, but it is new to be not limited to this practicality
The scope of type.
This utility model is a kind of combined type dual energy sources heating system, by electricity energy accumulation water heater group with
Air source heat pump water heater group " is combined ", and forming air can be with electricity accumulation of energy " dual energy sources "
Heating system, air source heat pump water heater group is that one-level preferentially heats up, and electricity energy accumulation water heater group is
Two grades of temperature controls heat up.Heated up by twin-stage and improve heating efficiency, make source pump all the time in efficiency
Run under the highest state.
As Figure 1-4, this utility model includes that air source heat pump water heater group 1, electricity store
Energy Hot water units 2, radiator 4, water circulating pump 3, voltage stabilization water filling device 5, described air energy
Heat-pump hot-water unit 1, electricity energy accumulation water heater group 2, radiator 4, water circulating pump 3, voltage stabilizing are mended
Water device 5 is sequentially connected with, and forms closed-loop water system.Described air energy heat pump be electric power or
Other power-actuated compression heat pumps.Described electric energy accumulation water heater group is that high-temp solid electricity stores
One in energy Hot water units, water accumulation of energy unit, steam accumulation of energy unit or phase-changing energy-storing unit.
System flow of the present utility model is: system return heats up through air source heat pump water heater group one-level,
Carry out two grades of intensifications subsequently into electricity energy accumulation water heater group, finally enter dissipating of heating system end
Hot device release heat, the water after cooling is again introduced into the circulation of air source heat pump water heater group.Described
Air source heat pump water heater group undertakes the main thermic load of system, and described electricity energy accumulation water heater group is held
Load supplemental heat load.During installation, electricity energy accumulation water heater group indoor location or outdoor mounted, empty
Gas energy heat-pump hot-water unit outdoor ground is installed or is maked somebody a mere figurehead and installs or be arranged on other buildings.
As Fig. 3 is arranged on roof for electricity energy accumulation water heater group indoor location, air source heat pump water heater group
Layout drawing.
As shown in Figure 4, heating system backwater is sent into air source heat pump water heater by water circulating pump 3
The condenser of group 1, air source heat pump water heater group 1, under the driving of electric energy, absorbs in air
Heat energy, recirculated water one-level warming temperature is risen to 45 DEG C by 40 DEG C, subsequently into electricity accumulation of energy
The heat exchanger of Hot water units 2, two grades are warming up to 50 DEG C, and the hot water after intensification enters heat supply system
The radiator 4 of system end, discharges heat, and water temperature is down to 40 DEG C, is again entered through water circulating pump 3
Enter air source heat pump water heater group 1, complete heating cycle.
When heating system (can enable air to heat-pump hot-water unit keep relatively when outdoor temperature is suitable
High COP ambient temperature), air source heat pump water heater group is operated at full capacity, electricity accumulation of energy hot water
Unit is changed to the real-time concurrent heating of system according to thermic load.
When heating system is in paddy electricity or ordinary telegram period, even ambient temperature is relatively low, COP is relatively low,
But because electricity price is cheap, when the comprehensive heating electricity charge are less than electricity accumulation of energy, air source heat pump water heater group is full
Load operation, electricity energy accumulation water heater group is changed to system concurrent heating according to thermic load.
When outside air temperature is higher, the efficiency of air source heat pump water heater group raises, end simultaneously
The requirement of water temperature is also reduced by radiator, and in this case, system only needs one-level to heat up, only
Open air source heat pump water heater group and just can meet system heat demand.
When heating system is relatively low in peak electricity period and outdoor temperature, heat pump COP declines, and combines
When closing the heat supply electricity charge higher than electricity accumulation of energy, heat pump stops or operation at part load, by electricity accumulation of energy hot water
Unit undertakes the main loads of system.
When ambient temperature is too low, air energy heat pump cannot run, or is in the peak electricity period, empty
In the case of the gas energy operation of heat pump electricity charge are higher, only open electricity accumulation of energy unit and carry out single-stage intensification.
The above is only preferred implementation of the present utility model, it is noted that for this skill
For the those of ordinary skill in art field, on the premise of without departing from this utility model know-why,
Can also make some improvement and modification, these improve and modification also should be regarded as of the present utility model
Protection domain.
