For the water temperature that makes photovoltaic water-raising system obtains comprehensive utilization, reaching to pump up water solves local water shortage problem, and can regulate the room temperature again provides the purpose of a home from home.The present invention utilizes photovoltaic water-raising system to power for motor, dragging water pump carries deep-well underground water to the face of land by water pipe, the characteristics cool in summer and warm in winter according to underground water resupply the ground water after allowing it by heat-exchanger rigs such as U type pipe groups, realize the function to indoor summer cooling, Winter heat supply.Can valving on water pipe in order to regulate U type pipe group water temperature and delivery port flow.
As one embodiment of the present invention, described solar photovoltaic generation system adopts power supply in support such as conventional power supply, adopts the back-up source power supply when solar energy is not enough.
As one embodiment of the present invention, described valve saves a part, utilizes residue valve regulated temperature and water flow, and perhaps described valve all saves, and does not carry out temperature and regulates and the delivery port flow-control.
As one embodiment of the present invention, described valve adopts water pump or compressor to replace, and regulates the heat exchange and the delivery port flow of U type Guan Zuyu environment by the control of water pump and compressor.
As one embodiment of the present invention, described U type pipe group adopts one or more U type pipes to be connected to each other and forms.
As one embodiment of the present invention, described photovoltaic generating system can be furnished with battery or electric capacity as energy storage device.
As one embodiment of the present invention, described U type pipe group is other can set up auxiliary equipment such as blower fan and promote heat exchange between water and the surrounding environment.
The technical solution adopted in the present invention is as follows:
The supply integrated system of a kind of photovoltaic water-raising and changes in temperature, mainly comprise solar photovoltaic generation system, motor, water pump, U type pipe group and valve etc., it is characterized in that: the present invention powers to the motor that places deep-well by solar photovoltaic generation system, motor drags water pump underground water is carried to the face of land by water pipe, water pipe one end links to each other with water pump, the other end links to each other with U type pipe group, because deep-well underground water has characteristics cool in summer and warm in winter, it is when the U type pipe group and surrounding environment generation heat exchange, be its cooling summer, and be its heating winter.The water that photovoltaic water-raising system pumps from deep-well can be stored in the pond by U type Guan Zuhou, also can directly take, and solves some areas water shortage problem.As one embodiment of the present invention, valve can be set on water pipe, in order to the water pressure of adjusting foggara and U type Guan Zuzhong, thereby can regulate the water temperature and the rate of discharge of U type pipe group.
Technique effect of the present invention is:
1. utilize solar photovoltaic generation system that the solar energy of clean environmental protection is converted to electrical energy transfer to motor, drive water pump, solve some areas water shortage problem from the deep-well water lift.
2. utilize deep-well underground water characteristics cool in summer and warm in winter, by U type Guan Zuwei cooling in indoor summer and heating in winter, economical and practical, energy-conserving and environment-protective, and have adaptive characteristics, when summer, sunshine was strong, indoor air temperature is higher, at this moment photovoltaic water-raising system pumps up water manyly, and the cooling cold is also many more, and the temperature regulating effect is good more.
