Problems solved by technology

[0003] The existing method has the following defects: ①The heat transfer efficiency is low
Usually, the indoor temperature is usually more than 10 degrees higher than the outdoor temperature, so the heat exchanged to the ground will be a lot, which will cause the underground temperature to rise sharply, and the temperature will increase day by day, which will lead to excessive heat accumulation during the day Difficult to dissipate, even unable to achieve cooling, causing the entire system to be paralyzed; ② Lack of groundwater resources
Many base stations are built in water-scarce areas. At the same time, pumping groundwater can easily pollute the environment, damage the geological structure, and easily cause geological subsidence. Now developed countries such as Europe and the United States do not use this method; ③There are no usable ponds and dams around most base stations or river courses, unable to use surface water resources for temperature control

Embodiment Construction

[0034] In order to solve the above technical problems, an embodiment of the present invention provides a system for adjusting indoor temperature. The system for adjusting the indoor temperature described in this embodiment uses the method of "internal circulation" to control the temperature inside the room, which is usually used to cool down the room.

[0035] figure 1 It is a schematic diagram of the internal structure of the system for regulating indoor temperature described in this embodiment. Such as figure 1 As shown, the system mainly includes:

[0036] The air guide pipe 1 buried in the ground, its air inlet is connected to the outside, and the air outlet is connected to the room, which is used to use the temperature of the soil around the air guide pipe to adjust the temperature of the air entering the pipe, and send the conditioned air into the room ;

[0037] The circulation pipe 2 has an air inlet connected to the chamber and an air outlet connected to the air i...

Abstract

The invention discloses a system and method for adjusting the indoor temperature. The method is as follows: when the outdoor temperature is low, outdoor air is used as a heat exchange medium: the outdoor air is led into a gas guidance pipeline which is buried underground at a certain depth, the air temperature in the pipeline is adjusted by using the soil temperature around the gas guidance pipeline, and the cooled air in the pipeline is delivered to the interior, so that the cooled low-temperature air is utilized to directly cool the indoor high-temperature; and when the outdoor temperature is high, the outdoor air is not used as the heat exchange medium any longer, and cooling is carried out by an inner circulation mode, the indoor low-temperature air is fed back to the underground pipeline for cooling again, and later, the cooled low-temperature air is led into the interior. By using the inner circulation mode, outdoor air with a high temperature does not need to be led in all the time to serve as a heat exchange medium, thus, load can not be brought to the underground soil, excess heat accumulation is not generated, and the heat exchange efficiency of the system is improved inno need of utilizing underground water and surface water resources, thereby omitting air conditioners.

Description

technical field [0001] The invention relates to the technical fields of civil engineering, HVAC, mechanical engineering and electronics, in particular to a system and method for adjusting indoor temperature. Background technique [0002] At present, there are three ways to use "geothermal" resources to achieve indoor temperature control: ①Using groundwater resources; ②Using surface water resources (such as ponds, dams or rivers); ③Vertical / horizontal U-shaped buried solid soil coupling pipes . The above three methods all use the characteristic that the soil temperature at a certain depth under the shallow surface is stable for many years, and can exchange the indoor heat with the heat under the shallow surface. When the indoor temperature is higher than the outdoor soil temperature, the performance To cool down; and when the indoor temperature is lower than the outdoor soil temperature, it shows as warming. [0003] The existing methods have the following defects: ①The hea...
