Heat supply heating is carried out, but during thermal source coolant-temperature gage minimum higher than driving source pump；Now, automatic control system 105 is according to input
Signal, the first on-off valve group 9 on the water inlet pipe 111 of source pump 11 first and the second water inlet pipe 113 is opened, second is led to
Disconnected valve group 10 is closed, and starts source pump 11, and system is switched to joint heat pump mode.
Auxiliary thermal source pattern, the pattern starts in the following two cases, and one kind is the leaving water temperature of thermal storage water tank 3 less than heat
Pump assembly water source side minimum temperature, one kind is that user has domestic hot-water's demand, but hot water effluent's temperature is not when reaching design temperature.
Start auxiliary thermal source under this pattern, so as to maintain the normal operation of source pump, prevent work from alarming, or make domestic hot-water's
Temperature reaches requirement.
The beneficial effect of multi-functional complementary heating plant is：
By optimizing the method for operation of solar thermal collection system, the system of source pump 11 and auxiliary thermal source system 6, ensureing
On the basis of heat demand, the new energy such as solar energy and regenerative resource are made full use of, energy complementation is formed with coupling heat supply
Pattern, and the device, towards family use, integrated level is higher, and unit scale is smaller, and use more facilitates.
From using water temperature interval, in existing solar heating circulation, the retaining temperature in thermal storage water tank 3 need to be higher than end
Heating supply water temperature is held, typically can just be come into operation more than 45 DEG C for direct-type system, is typically existed for indirect type system
More than 55 DEG C could come into operation indirectly, be respectively 45~95 DEG C or 55~95 DEG C using water temperature interval.The present invention is using heat
Pump assembly extracts low-temperature heat source, and water temperature just may participate in heat pump mode heating when being higher than 10 DEG C, be existing solar energy using the temperature difference
1.45 or 2.12 times of heating circulation.
From auxiliary energy system selection, combustion gas, oil, coal burning boiler, electrical heating, biomass boiler etc. can be made.Auxiliary energy
The setting of source system, can efficiently avoid influence of the extreme weather to heat supply.Such as continue the haze weather in one to two weeks, connect
The extreme weathers such as continuous cloudy day, adjust the temperature of thermal storage water tank 3, reach the heat source temperature requirement of source pump.
It is auxiliary in solar irradiation deficiency or without sunlight in traditional solar heating circulation from auxiliary energy system operation
Help the energy must to be fulfilled for the requirement of maximum heating load, largely result in the waste of the energy, solar insuring rate is relatively low, this hair
It is bright under supplying thermal condition, auxiliary thermal source is only enabled when thermal source coolant-temperature gage is less than the minimum inflow temperature of heat pump water source.Reduce
The live load of auxiliary heat supplying device.Under domestic hot-water's operating mode, the office that auxiliary thermal source can be only at heating domestic hot water's dry point
Portion's temperature, without heating whole water tank, is more saved while user hot water demand is met.
From Solar use, because thermal storage water tank 3 can be expanded using water temperature interval, the work temperature of solar thermal collection system
Degree is interval also corresponding to be expanded, and is on the one hand improved solar energy heating and was circulated for 102 opening times, on the one hand because source pump 11 exists
Heat source side inflow temperature just can be used when being higher than 10 DEG C, therefore the thermal-arrest cycle fluid mean temperature reduction in solar thermal collector 1,
The average normalized temperature difference reduces, and collecting efficiency and the solar energy heating amount of solar thermal collector 1 have been lifted, and further improves
The solar insuring rate of system and heating stability.
From heat exchange mode, three circulatory systems are independent closed system in device, wherein heat collecting and circulating system, heat
The source circulatory system is indirectly connected with thermal storage water tank 3, improves the retaining water quality inside thermal storage water tank 3, it is ensured that domestic hot-water supply
Safety, health.
From operation stability, thermal-arrest control strategy, thermal source control strategy and the end-of-pipe control strategy of robot control system(RCS) ensure
Solar thermal collector 1, source pump 11, auxiliary thermal source system 6, end heating equipment 13 etc. are under safe and efficient state
Operation, system possesses the function of report barrier and alarm.
From the system integration, the relatively conventional solar-heating heating circulation of the device is built towards family formula and researched and developed, integrated level
Higher, scale significantly reduces, most equipment and pipeline it is integrated be arranged on protective housing 200 in, noise can be completely cut off, strengthen
Heat extraction, improves aesthetics.Feature is compact, is easy to mobile and installs, convenient for the user to operate to use.
It is automatic to control from installing and using upper, Product Assembly degree height, installing and debugging process is transferred to factory's completion
System altitude processed is integrated, easy to operate, and user can be switched as conventional air conditioner to device, pattern and temperature etc. are adjusted
Section.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area
For technical staff, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made is any
Modification, equivalent substitution, improvement etc., should be included in the scope of the protection.
