Problems solved by technology

However, the convection formed by the hood and the opening of the cave doors and windows effectively improved the indoor wind environment of the cave, but at the same time caused the heat loss in the cave and changed the excellent thermal characteristics of the cave "warm in winter and cool in summer".

Abstract

The invention discloses a passive ventilation-dehumidification system of a soil-source-based immature soil cave dwelling. The passive ventilation-dehumidification system comprises fresh air pipes, wherein the fresh air pipes are obliquely arranged along the cave dwelling legs of the cave dwelling and buried in the soil; the slope of each fresh air pipe is lower than or equal to 20%; a soil source heat exchange device is connected in series with the fresh air pipes; three rows of the fresh air pipes are arranged side by side; the bottoms of all the fresh air pipes communicate with one another through a transverse connecting pipe; a U-shaped condensate water pipe and an air supply device are connected with the transverse connecting pipe; air pull-out devices are arranged on the top wall of a cave dwelling chamber; and air volume adjusting devices are arranged at the bottoms of the air pull-out devices. The invention further discloses a construction method of the above passive ventilation-dehumidification system. When the passive ventilation-dehumidification system disclosed by the invention is utilized for cooling or heating inside the cave dwelling, no energy and refrigerant are needed, and no environmental pollution is caused; meanwhile, the freshness of air inside the cave dwelling can be improved, thereby preventing air-conditioning diseases caused by the indoor cycle mode of a conventional air conditioner; and after construction, the existing appearance integrity and the original nature of the conventional cave dwelling can be prevented from being broken.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a temperature and humidity regulating structure for raw earth cave dwellings. Background technique [0002] Traditional raw earth cave dwellings have the architectural characteristics of being warm in winter and cool in summer, and are natural ecological residences. However, due to poor indoor ventilation, indoor mildew and condensation often occur, seriously affecting the living quality of cave dwellings. [0003] There are two known ventilation improvement technologies for traditional raw earth cave dwellings: 1) One is to use a split air conditioner, whose working principle is that the compressor sucks in low-pressure gaseous refrigerant, which is compressed into high-temperature and high-pressure gas; The gaseous refrigerant flows to the outdoor condenser, and gradually condenses into a high-temperature and high-pressure liquid during the process of heat dissipation...
