As used in the description herein and throughout the claims that follow, the meaning of in includes in and on unless the context clearly dictates otherwise.

[0019] It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the embodiments. As used herein, the term and/or includes any and all combinations of one or more of the associated listed items.

[0020] Referring to FIG. 1, a photovoltaic energy and thermal energy generated water and heat supply integral unit may include a photovoltaic energy accumulator 1, a thermal energy vacuum boiler 5, a water-use site 6 and a membrane walled heat recovery device 3. The photovoltaic energy accumulator 1 may include a photovoltaic hot plate 2, a water inlet 1.1 and a water outlet 1.2.

[0021] As shown in FIG. 2, the thermal energy vacuum boiler 5 includes combustor 5.7, thermal energy module 5.6, and hear-transferring tube 5.5; and combustor 5.7 is connected to air inlet 5.4 and exhaust vent 5.2, and thermal energy module 5.6 is also connected to air inlet 5.4 and exhaust vent 5.2, and both terminals of hear-transferring tube 5.5 are respectively connected to water inlet 5.1 and water outlet 5.3, and hear-transferring tube 5.5 is above combustor 5.7 and thermal energy module 5.6. Heat recovery device 3 is with water inlet 3.1, water outlet 3.2, air inlet 3.3 and air outlet 3.4. Water outlet 1.2 of photovoltaic energy accumulator is connected to water inlet 3.1 of heat recovery device. The water outlet 3.2 of heat recovery device is connected with water inlet 5.1 of thermal energy vacuum boiler. The water outlet 3.3 of heat recovery device is connected with water inlet 5.2 of thermal energy vacuum boiler. The air outlet 3.4 of heat recovery device is connected with the chimney 4. Water outlet 5.3 of thermal energy vacuum boiler is connected to water inlet 1.1 of photovoltaic energy accumulator, and one valve 7 is installed in this water inlet. Photovoltaic energy accumulator 1, thermal energy vacuum boiler 5 and membrane walled heat recovery device 3 form a loop circuit. A water-use site 6 is located between water inlet 1.1 of photovoltaic energy accumulator and water outlet 5.3 of thermal energy vacuum boiler; water inlet 1.1 of photovoltaic energy accumulator is also connected to the incoming water source and air inlet 5.4 of thermal energy vacuum boiler is connected to incoming air source. At water inlet 1.1 of photovoltaic energy accumulator, there is another valve 8, controlling the incoming of water resource.

[0022] When in use, the photovoltaic hot plate of photovoltaic energy accumulator absorbs all surrounding light energy effectively, which in term transforms into electricity for heating water, and this electricity will conduct initial heating of water within tube. The heated water flows past the heat recovery device into heat-transferring tube of thermal energy vacuum boiler. And the thermal energy module of the thermal energy vacuum boiler conducts a secondary heating of water. The further heated water is to supply the water-use site via pipe, and the surplus hot water will flow back to photovoltaic energy accumulator and, together with the later-coming water, flows out of water outlet of photovoltaic energy accumulator after heating.

[0023] When the water use volume increases at the water-use site or when the temperature is yet up to demand, natural gas flows from inlet of thermal energy vacuum boiler in to combustor and begins to burn and conduct supplementary heating of water within heat-transferring tube. Water heated by thermal energy and natural gas flows into water-use site via water outlet, or flows back to photovoltaic energy accumulator. The burnt natural gas flows via the exhaust vent of thermal energy vacuum boiler into the air inlet of heat recovery device to conduct surplus heating on water flowing into the heat recovery device, and the exhaust gas flows through air outlet of heat recovery device into the chimney. Hot water heated by photovoltaic energy and surplus heat flows into thermal energy vacuum boiler for a secondary heating, so as to guarantee water temperature within loop circuit of the photovoltaic energy and thermal energy generated water and heat supply integral unit is stable and meets demand for water use. When using water, water inlet valve of photovoltaic energy accumulator is open, so as to guarantee that water pressure of the photovoltaic energy and thermal energy generated water and heat supply integral unit is stable lest there occurs a low water-supply pressure.

[0024] Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalent.
