Description
Technical Field
The utility model relates to a warm braw device that high big space environment such as shopping mall used especially relates to a warm braw device that possesses air purification function suitable for cylinder.
Background
The heater is an important device for providing heat for the indoor. When the heater is used for heating a room in winter, due to the influence of the buoyancy lift force of heated air, the heater provides hot air which tends to accumulate towards the upper part of the room. The supply-air outlet of traditional warm braw device generally sets up on the upper portion in room for a large amount of heat gathering can not well be utilized in indoor upper portion space like this, causes the energy waste, and personnel's work activity district often is arranged in return air or the environment of airing exhaust moreover, and sanitary conditions is poor, and air supply efficiency is also low. With the development of cities, the number of tall indoor spaces (such as various large commercial centers, shopping malls and the like) is increasing. The above problem is particularly serious for these tall indoor spaces. The area of the tall space that needs heating is only the lower, passenger activity area, while the upper area does not need heating. However, under the action of the thermal buoyancy of air, the temperature of air at the upper part of the room is too high, and the energy consumption of the resulting ineffective heating is often very high. And the temperature distribution of the upper heat and the lower cold is contrary to the temperature distribution required by the thermal comfort of the human body, and the good heating effect can not be achieved. The high and large space buildings are provided with cylinders with supporting functions, such as cylinders, square columns, rectangular columns, polygonal columns and the like, which are positioned inside the buildings, are uniformly distributed and generally have no shelters. If the warm air device can be combined with the cylinder body to supply air at a low position, the air supply is more uniform, the sanitary condition is better, the energy can be saved, and the requirement of thermal comfort of the human body can be better met.
When using a heater, people pay attention to the quality of the air to be fed in, besides certain requirements on energy conservation and comfort. About 210 million people die worldwide each year from rising concentrations of particulate matter. PM (particulate matter)2.5On average 10. mu.g/m increase during one or two days of cultivation, the total mortality rate increases by 1.1% and 2.3%, respectively. Particles deposited in the respiratory tract can cause emphysema, asthma, pneumoconiosis and other diseases, so the inhalable particles are listed as human first-grade carcinogens. Therefore, it is necessary for the heater to have an air cleaning function. However, the existing suspended particle removal technology has low removal rate of small particles, and the small particles are the most harmful particle substances to human bodies. The phenomenon of 'Black Magic Dust' on the vertical wall surface above the near-wall heat source provides a new idea for removing small particles. The "Black Magic Dust" refers to a phenomenon that a large amount of stains appear on the surface of an indoor wall in a short time. The near-wall heat source emits heat and is close to the wall surface, so that a high-speed and high-temperature area is formed above the near-wall heat source, and particles are easier to deposit on the rear vertical wall. In recent years, although some methods for removing dust by using the phenomenon exist, the technology is not mature, the dust collecting area is not subjected to thinning and partitioning, emphasis and enhancement, and the related devices have single functions, the dust removing principle is not clear, so that the cost is high, and the energy consumption is high.
