Outdoor unit of ventilation system

Abstract

The invention discloses an outdoor unit of a ventilation system. The outdoor unit of the ventilation system comprises an air inlet and exhaust pipeline and an air inlet and exhaust device, the outdoorunit of the ventilation system is characterized in that the air inlet and exhaust pipeline is a nested type double-layer combined pipeline and is structurally divided into an inner pipe and an outerpipe, openings are formed in the inner pipe and the outer pipe correspondingly and lead to the interior and the exterior of a room; openings are formed in the outer pipe and the inner pipe correspondingly and lead to the interior and the exterior of a building, an outdoor opening of the outer pipe and an indoor opening of the outer pipe are formed in the two ends of the outer pipe correspondingly;an indoor opening of the inner pipe is close to one end of outdoor opening of the outer pipe and penetrates through the outer pipe wall to lead to the interior of the room, the outdoor opening of theinner pipe is close to one end of the indoor opening of the outer pipe and penetrates through the outer pipe wall to lead to the exterior of the room; and the air inlet and exhaust device is locatedin the air inlet and exhaust pipeline and comprises a first air supply component and a second air supply component, the first air supply component and the second air supply component communicate withthe inner pipe and the outer pipe respectively, and the air supply directions are different. The outdoor unit of the ventilation system can be widely used in building bidirectional flow ventilation systems, the exhaust air volume and the fresh air pressure are considered while the heat exchange function is provided, noise is reduced, and the size of an indoor unit is reduced.

Description

technical field [0001] The invention relates to fresh air ventilation equipment, which is an outdoor unit of a fresh air system. Background technique [0002] With the increasing attention to air pollution and safety hazards of decoration materials, and the rise of the concept of near-zero energy consumption buildings, fresh air fans have begun to be popularized on a large scale. There are two types of fresh air equipment currently on the market: one-way flow and two-way flow: [0003] One-way air intake or exhaust air in one direction, easy to install, but low ventilation efficiency, lack of low energy consumption means to maintain indoor temperature. [0004] The two-way flow fresh air fan has both air intake and exhaust, high ventilation efficiency, and can guide the airflow to cross through the heat exchange core to maintain the indoor temperature. However, the current mainstream two-way flow fresh air fan pipe and the main body of the fan are indoors, and the installa...
