1st, ultra-large type home use solar-powered water heater series-parallel connection type.
This type solar energy central hot water system has the movement simply, the ease of operation, the failure rate extremely low status characteristic, is suitable for the flat topping room installment, also the installment space is sufficient, inconveniently sets up unit, the collective and so on hospital, school, guesthouse, army, toll station which the full time personnel safeguards uses the hot water.
Movement principle: (Following graphical representation)
This system may according to need the multi- Taiwan ultra-large type home use solar-powered water heater series-parallel connection, cold water enters in the solar-powered water heater after the water monitor box to carry on heats up, then the inflow heat preservation water tank carries on the storage. Controls the cabinet to be possible to realize to the heat preservation water tank water temperature, the water level demonstration and the automatic electric heating function, maintains the water tank temperature to be constant.
2nd, connected set tubular solar energy collection heat unit combined type
This type solar energy central hot water system automaticity high, to installs the condition to limit slightly, mainly is suitable in uses the hot water volume big, the roof structure to be complex, the installment space unit and the collective use and so on hospital, school, guesthouse, army, residential district, toll station which limits. This kind of pattern solar energy hot water system divides into three kind of patterns: Decides the warm drainage system, the thermosyphon and decides warm turns on the water with the temperature difference circulation mixed type.
(1) decides the warm drainage system:
When in the collection heat temperature achieved when setting value, decides warm puts the water valve to open, the water flows in the heat preservation water tank to carry on the storage, the system may realize automatically makes up the water, the water temperature water level demonstration, the pipeline circulation and the automatic control electric heating and so on the many kinds of functions.
(2) thermosyphon: (Following graphical representation)
This system through in the hypothesis collection hot system outlet temperature and the heat preservation water tank wendu, may realize the circulating pump automatically to open shuts, causes in the heat preservation water tank cold water to enter the solar energy collection heat unceasingly, in the solar energy collection heat hot water goes against into the heat preservation water tank, causes in the water tank the water temperature to elevate unceasingly.
This system also may with other assistance energy (electricity, gas, oil and so on) match meets, realizes all-weather supplies the hot water.
(3) decides warm sails upstream + the thermosyphon
When in the collection heat temperature achieved when setting value, decides warm puts the water valve to open, cold water automatic interpolation solar energy collection heat, the collection heat internal heat water flows in the heat preservation water tank to carry on the storage, after the long time movement, in the water tank the water level achieved when controls water level which the cabinet establishes, automatically enters the temperature difference shuttle service way.
