Fresh air system and air conditioner

Abstract

The invention provides a fresh air system and an air conditioner. The fresh air system comprises a mounting box and a filtering part, the mounting box is provided with a first air duct and a second air duct which communicate with each other, and an included angle is formed between the extending direction of the first air duct and the extending direction of the second air duct; the filtering part is arranged in the connecting area of the first air duct and the second air duct and provided with a first air inlet face, and the first air inlet face is obliquely arranged towards the first air ductrelative to the direction perpendicular to the extending direction of the second air duct so as to reduce the resistance of air entering the second air duct from the first air duct. By the adoption ofthe scheme, the air entering from the first air duct enters the second air duct after being filtered by the filtering part, the first air inlet face inclines towards the first air duct relative to the radial direction of the second air duct, airflow in the first air duct enters the second air duct through the first air inlet face, and therefore the turning angle of the airflow passing through thefiltering part can be reduced, airflow losses are reduced, so that the air inlet amount is increased, and the vortex and noise of the airflow are reduced.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a fresh air system and an air conditioner. Background technique [0002] For common air conditioners, in order to ensure the cooling and heating effects, the room is usually closed, resulting in poor air flow in the room, and finally leads to the continuous increase of carbon dioxide and bacteria in the room, and the increase of the proportion of turbid air in the air, resulting in poor air quality. Along with paying attention to the quality of life, there is an urgent need to ventilate the airtight room and exhaust the indoor air to the outside to improve the air quality of the room. [0003] In order to improve indoor air quality, some air conditioners are equipped with fresh air systems. This kind of fresh air system needs to be arranged in a compact space, and the internal structure is also relatively complicated. The airflow also turns more inside the fresh...

AI Technical Summary

Problems solved by technology

This kind of fresh air system needs to be arranged in a compact space, and the internal structure is also relatively complicated. The airflow also turns more inside the fresh air system, mostly at 90 degrees, which causes greater resistance to the airflow and affects the intake of fresh air.
