Abstract

The invention provides a reliability design method and device of a buried pipe of a ground source heat pump, which are applicable to the technical field of ground source heat pumps. The method comprises the following steps: determining random parameter properties of a buried pipe system of the ground source heat pump; determining the possibility distribution of random parameters; establishing a reliability index of the buried pipe system of the ground source heat pump; establishing a function state model; calculating the reliability of the buried pipe system of the ground source heat pump according to the function state model. According to the reliability design method and device, an energy consumption random model and a distribution rule are established according to the factors including the structure of a building, a building design, structure form selection and the like; under the restriction conditions of the reliability index and an economy index, the buried pipe is designed and calculated according to an energy consumption index and the random heat transmission performance of the buried pipe and rock soil by considering the size of the buried pipe, backfill materials and environment conditions, so that a reliable scheme is provided for the design of the buried pipe of the ground source heat pump.

Description

technical field [0001] The invention belongs to the technical field of ground source heat pumps, and in particular relates to a reliability design method and device for buried pipes of ground source heat pumps. Background technique [0002] The design of buried pipes of ground source heat pumps is the key technology of ground source heat pumps. Due to the complexity of the nature of underground rock and soil, the design of buried pipes cannot meet the engineering needs. Ground-source heat pump buried pipes are coupled with rock and soil, showing complex and random characteristics, and significant uncertainty in the process of underground heat transfer. When considering material porosity and complex working conditions, the inherent random properties of the thermophysical parameters of rock and soil media cannot be ignored. Due to the extremely complex working environment of buried pipes of ground source heat pumps, the existing heat transfer design methods of buried pipes ar...
