Fresh air pretreatment geothermal exchange system

Abstract

The invention relates to a fresh air pretreatment terrestrial heat exchange system. The fresh air pretreatment terrestrial heat exchange system comprises an outdoor fresh air taking part, a terrestrial heat exchange part and an indoor fresh air treatment part, wherein the outdoor fresh air taking part, the terrestrial heat exchange part and the indoor fresh air treatment part are communicated through ventilation pipelines. The fresh air pretreatment terrestrial heat exchange system is characterized in that the outdoor fresh air taking part is arranged on the ground, the outdoor fresh air taking part comprises a fresh air port, a coarse-efficiency filter device, a medium-efficiency filter device, an electrostatic dust collector and a solid dehumidification device which are arranged in sequence from top to bottom and are communicated; the terrestrial heat exchange part comprises buried pipes, temperature measuring points which are formed on the buried pipes, pneumatic cleaning device reserved openings and flow measuring points; the indoor fresh air treatment part comprises a fresh air unit, a drain pipe, a fresh air valve, a plenum chamber and a fresh air pipeline.

Description

technical field [0001] The invention relates to a geothermal exchange system, in particular to a fresh air pretreatment geothermal exchange system. Background technique [0002] In the prior art, there is a buried pipe energy-saving ventilation system, and its unresolved problems mainly include: [0003] 1. In the original patent, the outdoor fresh air first enters the room through the buried pipe, and a filter device is installed at the entrance of the indoor fresh air unit, while no filter and dust collection device is installed at the outdoor fresh air inlet. Due to the serious outdoor air pollution in China, if the outdoor fresh air directly enters the buried ventilation duct without treatment, it will inevitably cause dust collection and microbial growth in the buried ventilation duct. In this way, the fresh air processed through the buried pipe will become a new source of pollution, and entering the room will deteriorate the indoor air quality. [0004] 2. The origin...

AI Technical Summary

Problems solved by technology

Due to the serious outdoor air pollution in China, if the outdoor fresh air directly enters the buried ventilation duct without treatment, it will inevitably cause dust collection and microbial growth in the buried ventilation duct.

In this way, the fresh air processed through the buried pipe will become a new source of pollution, and entering the room will deteriorate the indoor air quality

[0004] 2. The original patent lacks detailed calculation methods for the setting of technical indicators such as buried ventilation pipe material, buried depth, pipe length, slope, and wind speed

In actual engineering, since the amount of condensed water is closely related to the outdoor meteorological conditions, the amount of air supply and the cooling effect of the geothermal heat exchanger, there is a possibility that the amount of condensed water is relatively small, cannot be collected, attached to the pipe wall, and cannot be discharged. Problems with dust accumulation and mold growth

The original patent did not consider taking corresponding technical measures to solve this problem

[0006] 4. The original patent lacks the monitoring function of the actual operation effect of the geothermal exchange system

There is a lack of monitoring of the effect of fresh air pretreatment, and it is impossible to judge whether the system operation has achieved the expected effect
