Distributed plateau geothermal heating system

Abstract

The invention provides a distributed plateau geothermal heating system which comprises distributed heat source collecting mechanisms, a heat pump unit and heat supply mechanisms; the distributed heatsource collecting mechanisms are double-pipe heat exchangers and are uniformly distributed; and a heat exchange side of the heat pump unit is connected with output ends of the double-pipe heat exchangers through a heat collection pipeline and connected with input ends of the double-pipe heat exchangers through a heat exchange pipeline, and a use side of the heat pump unit is connected with input ends of the heat supply mechanisms through a heat supply pipeline and connected with output ends of the heat supply mechanisms through a heat return pipeline. According to the distributed plateau geothermal heating system, the heat source collecting mechanisms which are uniformly distributed at equal intervals are adopted for collecting heat and supplying heat, so that the occupied area is reduced;the closed double-pipe heat exchangers are adopted as the distributed heat source collecting mechanisms and filled with a heat storage body, so that the heat exchange rate is effectively decreased, the heat exchange area is increased, and the heat exchange effect is improved; and the heat supply mechanisms can be arranged in different facilities, energy supply is partitioned, and energy can be supplied separately, so that waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of ground source heat pumps, and in particular relates to a distributed plateau geothermal heating system. Background technique [0002] At present, hydrothermal geothermal resources are developing rapidly as clean heating energy, especially in plateau areas where hydrothermal geothermal resources are abundant. When the same community in the plateau area uses geothermal wells for heating, the locations of geothermal wells are relatively messy, occupy a large area, and supply heat to various areas at the same time, and cannot be adjusted in time according to the energy supply demand, resulting in a certain waste. [0003] Therefore, developing a geothermal heating system suitable for the plateau environment in view of the above problems is a difficult problem urgently needed by those skilled in the art. Contents of the invention [0004] In order to solve the above problems, the invention discloses a distr...
