Method and system for supplying power to equipment using thermoelectric generation of pipelines

Abstract

The invention relates to a method and a system for supplying power to equipment using thermoelectric generation of pipelines and particularly relates to a method and a system for supplying power to equipment using a temperature difference of fluids in supply and return pipes of a heat supply or air-conditioning system. As the supply pipe and the return pipe of the heat supply or the air conditioning system have a stable temperature difference, fluids of high and low temperatures are guided into a thermal-cooling cycling cavity of a generating sheet generation system, the temperature difference between cold and hot surfaces of a generating sheet is maintained stable for stable power generation, and a control circuit is used for supplying power to the equipment or charging an electrical storage device. The circulation power of the fluids in the cycling cavity is from a pressure difference of the supply pipe and the return pipe of the heat supply or the air conditioning system and a pressure difference of a certain distance between an upstream and a downstream of the same pipe.

Description

technical field [0001] The invention belongs to the field of energy technology, and relates to a method for generating power to equipment by utilizing temperature difference in pipelines, in particular to a method for generating power for equipment by using the temperature difference to generate power for equipment when there is a temperature difference in the fluid in the water supply and return pipelines of a heating or air-conditioning system. It also relates to a system for implementing power supply of equipment by using the method. Background technique [0002] In the field of heating and air conditioning, the measurement of pressure, temperature, flow and other parameters of traditional water systems mostly use mechanical instruments, which can read, collect and record measurement data through dial display, manual reading, and pen and paper records. The operation of the system is then managed based on these read or recorded data. With the development of automatic cont...

[0003] The Chinese patent "A device for power generation by using the surface temperature difference of oil and gas pipelines (People's Republic of China, application number: 201420195588.6)" proposes a device for power generation by using the surface temperature difference of oil and gas pipelines, which uses the temperature between the surface of oil and gas pipelines and the external environment Although this method can realize power generation theoretically, it has the following disadvantages: First, the hot surface of the power generation sheet is in direct contact with the wall of the pipe, and the outer wall of the pipe is inevitably uneven and even corroded. and other problems, the contact thermal resistance of the wall surface of the power generation sheet is large, and it is difficult to make full use of the temperature of the fluid; the second is the method of using the ambient temperature to maintain the cold surface. Generally speaking, oil and gas pipelines are buried underground, and the thermal conductivity of the soil is poor. As the power generation process progresses, the temperature of the soil in the external environment will gradually increase, which will easily cause the temperature difference between the hot and cold surfaces of the power generation sheet to disappear, and the power generation capacity will be lost. The simultaneous loss of energy "quality" and "quantity"
