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 and dehumidification system for a soil source-based raw soil cave dwelling, which comprises a fresh air duct arranged obliquely along the kiln legs of the cave dwelling, the fresh air duct is buried in the soil and its slope is less than or equal to 20%; the fresh air duct is connected in series It is connected with a soil source heat exchange device, and the fresh air pipes are arranged in three rows side by side. The bottom of each fresh air pipe is connected to each other through a horizontal connecting pipe, and the horizontal connecting pipe is connected with a U-shaped condensate pipe; the horizontal connecting pipe is connected with an air supply device; The top wall is provided with an air extraction device, and the bottom of the air extraction pipe is provided with an air volume adjustment device. The invention also discloses a construction method of the passive ventilation and dehumidification system. The present invention cools or heats up the inside of the cave, without energy or refrigerant, without causing environmental pollution, and can improve the freshness of the air inside the cave, preventing "air conditioning" caused by the "indoor circulation" of the traditional air conditioner. disease", and the integrity and originality of the existing appearance of traditional cave dwellings will not be destroyed after construction.

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...
