Embodiment 1

[0028] see Figure 2 to Figure 3 , as illustrated therein, a soft-draft displacement-ventilated building comprising:

[0029] The room body 10 is distributed with one or more belt-shaped people gathering areas;

[0030] The air supply system 20, the air supply system 20 includes a fresh air delivery end 21 connected to the interior of the room body 10, the location of the fresh air delivery end 21 is lower than the position of the mouth and nose of the human body in the band-shaped personnel gathering area, and the fresh air delivery end 21 is a fiber cloth air duct ;

[0031] Exhaust system 30. The exhaust system 30 includes a turbid air receiving end 31 connected to the interior of the room body 10. The position of the turbid air receiving end 31 is higher than the position of the mouth and nose of the human body in the band-shaped crowd gathering area. The fresh air sending end 21 is made of fiber cloth. air duct;

[0032] A cooling and heating system, the above-mentione...

Embodiment 2

[0051] see Figure 4 , as shown in the legend, the rest is the same as the first embodiment, the difference is that there is a belt-shaped people gathering area distributed in the room, the fresh air sending end is set on the ground or corner of the room or the lower end of the wall, and the turbid air receiving end It is located on the top wall or the upper end of the wall of the room body.

[0052] In this embodiment, in a small office / room, cool air with a speed of less than 0.2m / s is sent from the bottom of one side of the room, through the heat radiation at the bottom, and the heat provided by the heat source of the human body in the room. The hot and dirty air together reaches the top area of ​​the ceiling and then exits the room over the other side. There is almost no polluting gas in the work area, avoiding indoor cross-infection and improving the health of the indoor environment, which can effectively reduce the demand for fresh air volume and reduce energy consumpti...

Abstract

The invention discloses a displacement and ventilation type building with a soft air supply function. The displacement and ventilation type building comprises a room body, an air supply system and an exhaust system, wherein the air supply system is used for inputting fresh air into the room body; the exhaust system is used for exhausting foul air from the room body; an indoor heating device and an indoor refrigerating device are arranged in the room body; one or more personnel gathering areas are distributed in the room body; the air supply system comprises a fresh air discharging end and a fresh air temperature adjusting device, wherein the fresh air discharging end communicates with the interior of the room body; the fresh air temperature adjusting device is used for adjusting the temperature of fresh air; the fresh air discharging end is lower than the mouth and the nose of a human body in each personnel gathering area; the exhaust system comprises a foul air receiving end communicating with the interior of the room body; the foul air receiving end is higher than the mouth and nose of a human body in each personnel gathering area; and the fresh air discharging end is a fiber cloth air pipe. According to the displacement and ventilation type building with a soft air supply function disclosed by the invention, a fiber fabric air pipe (Sorth system) is introduced into a fresh air system of a passive house to serve as a lower air supply pipe groove, so that uniform and low-speed air supply is achieved, and generation of turbulent flow is avoided.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a displacement-ventilated building with soft air supply. Background technique [0002] The principle of displacement ventilation is based on the rise of hot air and the fall of cold air formed by the difference in air density. Air is supplied from the bottom of the room at a wind speed of less than 0.2m / s and lower than the indoor air temperature. The displacement ventilation system has been used in high heat load industrial buildings in Europe for more than 40 years. In 1978, a foundry in Berlin, Germany first adopted the displacement ventilation device. In the past 30 years, displacement ventilation systems have gradually become popular in non-industrial buildings in Nordic countries, such as office buildings, schools, theaters, etc., such as the Copenhagen Grand Theater in Denmark. In my country, Tsinghua University conducted research on the operati...
