3. be based primarily upon solar energy and ground source can the building energy supplying system provided multiple forms of energy to complement each other of wisdom, it is characterised in that: the confession
The water outlet of solar heat storage water tank (2) is directly connect with the water inlet of energy supply end (6) in energy system, and energizes end (6)
Water outlet connect to form circulation loop all the way with the water inlet of solar heat storage water tank (2) by water pump, in this energy supplying system
Solar energy PV/T component (1) can be energized individually, when weather condition is preferable, be obtained using solar energy PV/T component (1)
Heat can make the temperature in solar heat storage water tank (2) reach indoor heating demand, so as to by solar heat storage water tank
(2) heat directly is provided for energy supply end (6), meets user demand, this process is not required to open ground heat exchanger (3) and water source
Heat pump (5)；
Solar energy PV/T component (1)-ground heat exchanger (3) combined operation approach, when weather condition is good, by solar energy
PV/T component (1) institute heat-collecting capacity is stored in solar heat storage water tank (2), using ground heat exchanger (3), will be obtained from soil
The heat obtained is stored in mixing tank (4)；Then, by the water and mixing tank of higher temperature in solar heat storage water tank (2)
(4) the water mixing in, as the low-temperature heat source of water resource heat pump (5), is stored in middle warm water for heat provided by water resource heat pump (5)
Case (7)；It is finally that energy supply end (6) provides heat by medium temperature water tank (7), meets user demand, non-heating season section, by solar energy
The heat that PV/T component (1) obtains is delivered to ground heat exchanger (3) by mixing tank (4), uneven in temperature to balance the summer in winter
Caused by heat loss.
4. be based primarily upon solar energy and ground source can the building energy supplying system provided multiple forms of energy to complement each other of wisdom, it is characterised in that: it is described too
The waste heat of photovoltaic cell passes to the liquid for traversing photovoltaic module by the thermally conductive of micro heat pipe array in positive energy PV/T component (1)
Body straight tube, the piping connection of the straight tube and the energy supplying system of providing multiple forms of energy to complement each other.
