Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and air exchange, in particular to a ventilation and air exchange facility for energy saving and emission reduction in buildings. Background Art

[0002] Energy conservation in buildings refers to reducing energy consumption as much as possible while meeting the same needs or achieving the same purpose during the production of building materials, construction of houses and structures, and their use. Energy conservation in buildings was initially aimed at reducing energy loss in buildings in developed countries. It is generally referred to as "improving energy utilization in buildings." While ensuring improved building comfort, it uses energy rationally and continuously improves energy efficiency. Ventilation facilities, also known as ventilation, use mechanical or natural methods to deliver sufficient fresh air into indoor spaces, while expelling dirty air that does not meet hygienic requirements, so that indoor air meets hygienic requirements and production process needs. In the steps of completing ventilation in existing buildings, there are still some problems when using existing building ventilation facilities:

[0003] 1. The facility is prone to clogging. Due to long-term ventilation, outdoor air needs to be drawn into the room for air replacement. Outdoor air often contains a lot of dust, which produces PM2.5. Therefore, it is necessary to use filtering methods to purify the air entering the room. However, due to the high dust content, long-term operation will cause the filter mesh inside the ventilation facility to be clogged, thus affecting the overall ventilation effect.

[0004] 2. Poor demand for improvement. Existing building ventilation facilities often only purify the air when replacing indoor and outdoor air, and then discharge it directly into the room. However, due to different outdoor air conditions in different regions, problems such as humidity, low air temperature, and dry air may occur. Directly discharging such air into the room for replacement can cause human discomfort. Utility Model Content
