本文主要研究的是亚热带地区内住宅建筑混合通风技术以及节能效果，此次研究

This paper mainly studies the hybrid ventilation technology and energy-saving effect of residential buildings in subtropical regions. The specific work of this research is as follows. <br>First, the calculation method of the best ventilation times for bedroom ventilation and energy saving in a universal residential environment is clarified. A wide range of investigations have been carried out on residential buildings in recent years, and the basic parameters of the bedrooms in the residences can be mastered and the geometric models of the bedrooms can be constructed. <br>The problems solved by the ventilation and air-conditioning system designed in this study are two points: sanitary ventilation and comfortable ventilation in residential buildings. There is a certain linkage control between the air conditioning system and comfort and ventilation, which can ensure that the residence can be ventilated with the help of natural resources to the greatest extent possible, so that indoor comfort and air quality are guaranteed.

This paper mainly studies the mixed ventilation technology and energy-saving effect of residential buildings in subtropical areas. The specific work of this research is as follows.<br>Firstly, it defines the calculation method of the best ventilation times for bedroom ventilation and energy saving in the universal residential environment. Based on the extensive investigation of residential buildings in recent years, we can master the basic parameters of bedrooms and build the geometric model of bedrooms.<br>The ventilation and air conditioning system designed in this study solves two problems: sanitary ventilation and comfortable ventilation of residential buildings.

This paper mainly studies the mixed ventilation technology and energy-saving effect of residential buildings in subtropical areas. The specific work contents of this study are as follows.Firstly, the calculation method of the best ventilation frequency for bedroom ventilation and energy saving in universal residential environment is defined. In recent years, extensive investigation on residential buildings has been carried out, and the basic parameters of bedrooms in residential buildings can be mastered and geometric models of bedrooms can be constructed.The ventilation and air conditioning system designed in this study solves two problems: sanitary ventilation and comfortable ventilation in residential buildings. There is a certain linkage control between the air conditioning system and comfort and ventilation, which can ensure that the house can be ventilated with the help of natural resources as much as possible, thus ensuring indoor comfort and air quality.
