Embodiment 1

[0025] The residential heat and power cogeneration method of the present invention comprises the following steps:

[0026] 1) Build a solar pool 3 with an area of ​​60m in a place with sufficient light around the residence 1 2 The geometric shape of the pool surface is selected according to the lighting conditions in the courtyard. The pool depth is 2.0m. The pool wall adopts a masonry concrete structure. After 25 days, a U-shaped heat exchange tube 4 with an inner diameter of Ф50mm and a length of 20m is installed in the pool.

[0027] 2) Drill a well 2 in the courtyard of the residence 1. The depth of the well is 60m. The inner diameter of the well is Ф30mm.

[0028] 3) Connect the heat exchange tubes 5 in the well to the heat exchange tubes 4 in the pool, and connect to the water inlet and outlet of the heat exchanger 12 in the house 1 through connecting pipes 10 .

[0029] 4) After the heat exchange tubes of the well and the pool are connected, put 0.5 tons of salt and 2...

Embodiment 2

[0034] The residential heat and power cogeneration method of the present invention comprises the following steps:

[0035] 1) Build a solar pool 3 with an area of ​​80m in a place with sufficient light around the residence 1 2 , The geometric shape of the pool surface is selected according to the lighting conditions in the courtyard. The pool depth is 2.5m. The pool wall adopts a masonry concrete structure. After 45 days, a U-shaped heat exchange tube 4 with an inner diameter of Ф100mm and a length of 40m is installed in the pool.

[0036] 2) Drill a well 2 in the courtyard of the house 1, the well depth is 120m, and the inner diameter of the well is Ф50mm.

[0037] 3) Connect the heat exchange tubes 5 in the well to the heat exchange tubes 4 in the pool, and connect to the water inlet and outlet of the heat exchanger 12 in the house 1 through connecting pipes 10 .

[0038] 4) After the heat exchange tubes of the well and the pool are connected, put 1.5 tons of salt and 1.5K...

Embodiment 3

[0043] The residential heat and power cogeneration method of the present invention comprises the following steps:

[0044] 1) Build a solar pool 3 with an area of ​​70m2 in a place with sufficient light around the residence 1 2 The geometric shape of the pool surface is selected according to the lighting conditions in the courtyard. The pool depth is 2m. The pool wall adopts masonry concrete structure. Days later, a U-shaped heat exchange tube 4 with a tube inner diameter of Ф80mm and a tube length of 30m was installed in the pool.

Abstract

The invention provides a combined heat and power method for a house, which belongs to the technical field of utilization of renewable energy sources. The method comprises the following steps: firstly, a pond is built at a position around the house where irradiation of light is enough; secondly, a well is dug in the yard of the house; thirdly, a heat exchange tube in the well and a heat exchange tube in the pond are communicated; fourthly, a running gradient slope of a solar pond is designed; fifthly, the bottom of the solar pond is provided with an electro-optical system; sixthly, an indoor heat exchanger of the house is arranged; and finally, the heat exchange tube in the well and the heat exchange tube in the pond are communicated, plain water is filled, and a forcible closed cycle is carried out under the action of a timed inline pump. The combined heat and power method for the house has high photoelectric transformation efficiency and low generating cost, and fully saves the area of a photovoltaic cell. If the design of the area of the solar pond is reasonable, the daily power utilization of an independent house can be satisfied.

Description

(1) Technical field [0001] The invention relates to a renewable energy utilization technology, in particular to a combined heat and power utilization method for residential buildings that combines shallow geothermal heat, solar pool heat collection and photovoltaic power generation technologies. (2) Background technology [0002] At present, the thermal insulation performance of rural residential buildings is poor, and there are problems such as high energy consumption of air conditioning in summer and winter, and serious air pollution. In order to solve this problem, fully consider the advantages of rural land that is basically unrestricted, thus introducing solar pool thermal energy utilization technology and Fresnel lens photovoltaic power generation technology. (3) Contents of the invention [0003] The technical task of the present invention is to provide a residential heat and power cogeneration method with reasonable design, low investment cost, energy saving and en...
