Self-circulation culvert type natural ventilation equipment

Abstract

The invention discloses self-circulation culvert type natural ventilation equipment, which comprises a straight-through wind pipe for communicating the internal environment with the external environment of a house, wherein straight-through wind pipe is divided into a first passage and a second passage which are longitudinally symmetrical with each other by a baffle plate which is horizontally arranged along the axial direction of the straight-through wind pipe; the first passage and the second passage are communicated with an upward first wind gap and a downward second wind gap respectively by getting close to the inside of the house; and the first wind gap and the second wind gap are provided with linkage switch valves. The self-circulation culvert type natural ventilation equipment performs air convection by using indoor and outdoor heat pressure differences to ensure that hot air flows indoors from one passage and indoor cold air is discharged out from the other passage so as to realize the natural circulation of fresh air feeding and discharging without additional powder, and controls the outdoor fresh air volume introduced indoors to reduce air-conditioning cooling load or heating thermal load losses caused by excessive fresh air introduction so as to meet requirements on energy saving; besides, the self-circulation culvert type natural ventilation equipment has the functions of thermal insulation, sound insulation, dust prevention and insect prevention.

Description

technical field [0001] The invention relates to a two-way ventilation device for air exchange in residential houses, in particular to a self-circulating culvert type natural ventilation device used in air-conditioned rooms to maintain indoor and outdoor air pressure balance. Background technique [0002] With the improvement of people's requirements for quality of life, the use of air conditioners in residential buildings is becoming more and more common. When the air conditioner is in use, in order to improve the indoor cooling or heat preservation effect, the room needs to be sealed. Due to the lack of convection between air and outdoor air in air-conditioned rooms, people who stay in the air-conditioned room for a long time will feel hypoxia, water shortage, chest tightness, and difficulty breathing. Moreover, the air of germs after breathing circulates indoors, which is easy to cause cross-infection of infectious diseases. Greatly endanger people's health. If the above...

Problems solved by technology

But the ventilation device of the window type air conditioner of this structure mainly has the following deficiencies: 1. Although the ventilation rate of the ventilation device of the window type air conditioner can be adjusted, if the adjustment is too large, the cooling capacity of the air conditioner will be affected; It cannot automatically promote indoor and outdoor air convection, so it is not suitable for use in air conditioners; 2. When in use, it cannot play the role of heat insulation, sound insulation and dust prevention; 3. Installed on the window, the installation position is single, and the installation The position is limited, the versatility is not strong, and the operation is inconvenient; 4. The structure is complex and the cost is high
