Unpowered ventilation device

Abstract

The invention discloses an unpowered ventilation device. The unpowered ventilation device comprises an exhaust pipe, an air inlet pipe, an impeller, a first heat pipe, a second heat pipe and a separation plate; the exhaust pipe communicates an indoor space with an outdoor space; one end, which is located outdoors, of the exhaust pipe is provided with a rotary air cap; the air inlet pipe penetratesthrough the pipe wall, which is located indoors, of the exhaust pipe form the pipe, which is located outdoors, of the exhaust pipe and extends indoors; the pipe wall, which is located outdoors, of the exhaust pipe is provided with an outdoor air inlet which communicates with the air inlet pipe through a communication block; the impeller is arranged in the air inlet pipe and is connected onto therotary air cap through a transmission connection rod; the evaporation section and the condensation section of the first heat pipe are located on the inner and outer parts of the air inlet pipe; the condensation section and the evaporation section of the second heat pipe are located on the inner and outer parts of the air inlet pipe; the separation plate separates the first heat pipe from the second heat pipe and divides the exhaust pipe into a first exhaust passage and a second exhaust passage; and the first and second exhaust passages are internally provided with a first exhaust valve and a second exhaust valve correspondingly. By adopting the unpowered ventilation device, sufficient fresh air is provided for the indoor space; besides, the indoor heat loss can be lowered; and the utilization rate of energy is improved.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to a non-powered ventilation device. Background technique [0002] Reasonable use of natural ventilation can adjust indoor thermal comfort, supplement fresh air, and create a healthy, comfortable and efficient working and living environment for people. For buildings such as offices and residences without centralized fresh air, natural ventilation is mainly achieved by opening doors, windows, etc. to form drafts, but this will bring a series of negative effects. During the air-conditioning or heating season, opening doors and windows will cause a large amount of cold or heat loss, which is a serious waste of energy; if the doors and windows are closed, it is not conducive to replenishing fresh air, improving indoor air quality, and causing serious negative effects on people's physical and mental health. influences. In addition, if the building is close to the street, directly o...

For buildings such as offices and residences without centralized fresh air, natural ventilation is mainly achieved by opening doors, windows, etc. to form drafts, but this will bring a series of negative effects

During the air-conditioning or heating season, opening doors and windows will cause a large amount of cold or heat loss, which is a serious waste of energy; if the doors and windows are closed, it is not conducive to replenishing fresh air, improving indoor air quality, and causing serious negative effects on people's physical and mental health. influences

In addition, if the building is close to the street, directly opening the doors and windows will cause greater noise pollution
