Horizontal buried pipe system

Abstract

The invention belongs to the field of heat exchanging equipment and relates to a horizontal buried pipe system. A horizontal buried pipe is laid in the underground soil, an input end and an output end of the horizontal buried pipe are connected with a ground source heat pump on the ground respectively, a separated type heat pipe is arranged above the horizontal buried pipe, and gravity type heat pipes are vertically arranged below the horizontal buried pipe. The horizontal buried pipe system has the advantages of efficient heat transmission characteristics of the heat pipes are utilized to improve heat exchanging efficiency between the horizontal buried pipe and the deep soil, so that heat exchanging amount is increased, occupied area is saved, and the horizontal buried pipe system is simple in structure, stable, efficient and reliable.

Description

technical field [0001] The invention belongs to a buried pipe of a ground source heat pump, in particular to a horizontal buried pipe system capable of efficiently exchanging heat with soil and saving space. Background technique [0002] With the increasing urgency of the energy crisis, the research and application of energy-saving technology has been developed rapidly. Among them, the technology of using the soil with good temperature properties under the surface as the heat source (or cold source) of the ground source heat pump is more and more widely used. This is because the temperature characteristics of the soil source are superior to those of the air source when cooling or heating, making the ground source heat pump more energy-saving than the air source heat pump. With the popularization of ground source heat pump devices, buried tube heat exchangers are an important part of ground source heat pumps, and their ability to exchange heat with soil has drawn extensive ...

Problems solved by technology

At present, buried pipes are mainly divided into two types. One is the vertical buried pipe that needs to be drilled. At present, the existing problems are: 1. The well drilling has a certain depth and the cost is high; 2. The buried pipe during construction The separation bracket between them is easy to be damaged, which will cause a local heat short circuit and reduce the performance of the heat pump unit.

The current problems are: 1. It covers a large area; 2. When used for a long time, the soil with weak groundwater flow will cause local heating, making the heat pump run uneconomically

The combined use of heat pipes and buried pipes has not been reported yet
