Building air conditioning method device utilizing solution cavity climate

Abstract

The invention discloses a solution cavity climate building air conditioning method and a solution cavity climate building air conditioning device. A house building is built above a solution cavity, air in the solution cavity is firstly introduced into an air static pressure chamber, then, the air in the air static pressure chamber is supplied into air conditioner using rooms in the house building through an air supply well, the replaced air is sucked out from the air conditioner using rooms through an outer wall exhaust passage via a heating air box, and in addition, the sucked air is exhausted into atmosphere through an exhaust opening, so the goal of conditioning the air in the building through the solution cavity climate is realized. The air pressure difference between internal and external of the solution cavity is utilized, under the condition without using energy sources, the air in the solution cavity is conveyed into the air static pressure chamber and is then supplied into the air conditioner using room through the air supply well, the goal of introducing solution cavity air with good heat comfort and high air quality is realized, and the air in the room is exhausted out of the chamber after replacement. The air exchange can be realized without using energy sources, so the energy sources can be effectively saved, and the environment is protected.

Description

technical field [0001] The invention relates to an air conditioning method and device, in particular to a building air conditioning method for karst cave climate. Background technique [0002] The United Nations Special Committee on Climate Change (IPCC) released the fourth assessment report. In the 21st century, with the warming made by humans, it will lead to the El Niño phenomenon of extremely hot summer and extremely cold winter, and the temperature on the earth's surface will continue to rise. The rise is even irreversible. Affected by this climate, future buildings will need to consume a lot of energy and emit more carbon dioxide to meet the needs of human comfort. [0003] Karst caves exist in karst karst areas. China has the largest karst karst continuous belt in the world and the largest number of karst caves on the earth. Since carbonate caves are underground, there is no change in direct solar radiation and scattered radiation from the sky, so caves The climate i...

AI Technical Summary

Problems solved by technology

[0004] There are currently two types of air-conditioning systems using lithospheric energy as buildings: buried pipes and ground-source heat pump air-conditioning systems, and underground displacement ventilation air-conditioning systems, but these two systems have the following disadvantages: ① buried pipes and ground Source heat pump air conditioning system: through buried water pipes and ground source heat, after heat exchange in the lithosphere, a circulation system between the building and the lithosphere is formed, so the structure distribution of rock layers, temperature distribution, groundwater temperature, runoff direction and the flow rate determine the feasibility and economical investment of the system, and once the buried water pipe leaks, it will cause pollution to the ground water source

In the lithosphere, the air density after heat exchange is lower than that of the atmosphere, forming a bottom-up ventilation airflow into the room, but the system is affected by the atmosphere and the lithosphere, and the ventilation efficiency is not high. Mechanical exhaust, and the excavated tunnels or laid underground air pipes need to be of sufficient length to meet the heat exchange requirements, which can easily cause environmental damage to the construction

③The working principle of the buried pipe and ground source heat pump air conditioning system: use water as a cold (heat) source to adjust the air in the building; the working principle of the underground displacement ventilation air conditioning system: directly extract the outdoor air and replace the indoor air. They can only adjust the air in the building, but cannot purify the air pollutants (TSP) in the indoor air

The above ①, ②, and ③ illustrate that their technical systems are designed to improve the indoor environment of the building on the basis of introducing atmospheric air into the building interior. They can only be regarded as an environmental protection system for improving thermal engineering, and cannot completely purify the atmosphere. air or as a low-power energy-saving system. Due to the technical defects of the two systems, they cannot cope with the climate change of the 21st century with rising temperatures.
