Building ventilation system with temperature adjusting function

Abstract

The invention discloses a building ventilation system with the temperature adjusting function. The building ventilation system comprises a positive pressure air duct system and a negative pressure air duct system. The positive pressure air duct system is provided with an air inlet pipe (1) and a positive pressure air shaft (2), the negative pressure air duct system is provided with a negative pressure air shaft (3) for exhausting air, a temperature adjusting device is arranged inside the positive pressure air shaft (2) and is a ground source heat pump, and an air cleaning device (8) is arranged inside the air inlet pipe (1). According to the building ventilation system, natural ventilation can be formed through the cooperative usage of the positive pressure air duct system and the negative pressure air duct system, the air can naturally flow, and the ventilation and temperature adjusting effects of a building are enhanced. The temperature adjusting device is arranged inside the positive pressure air shaft to adjust the inlet air temperature, the air with the appropriate temperature can be supplied into a room all the year round, the airflow is even, and a comfortable temperature environment is formed. The air cleaning device is arranged inside the air inlet pipe and filters the bacteria and dust in the inlet air, and the quality of the indoor air is improved.

Description

technical field [0001] The invention relates to a building ventilation system, in particular to a building ventilation system capable of temperature regulation. [0002] Background technique [0003] Buildings generally adopt natural ventilation, which relies on the wind pressure caused by indoor and outdoor wind or the heat pressure caused by the temperature difference between indoor and outdoor to make fresh air enter the room, and the indoor air is exhausted to the outside. Generally, the natural ventilation of traditional buildings is formed by convection, which requires that the orientation of the building must face the wind direction, but the wind direction is changing, and the doors and windows cannot be opened when the wind is strong, and there is no comfortable air quality in the home for a large part of the time. At the same time, due to the increasingly serious air pollution, such as the smog weather caused by PM2.5 pollution in the north, the quality of indoor ...

Problems solved by technology

Generally, the natural ventilation of traditional buildings is formed by convection, which requires that the orientation of the building must face the wind direction, but the wind direction is changing, and the doors and windows cannot be opened when the wind is strong, and there is no comfortable air quality in the home for a large part of the time. At the same time, due to the increasingly serious air pollution, such as the smog weather caused by PM2.5 pollution in the north, the quality of indoor air in natural ventilation is reduced, which has an impact on human health.

Buildings generally use air conditioners to control the indoor air temperature, but there is a large energy consumption, and the room must be airtight, there is no indoor and outdoor air exchange, and the indoor air quality is poor
