Central fresh air purification system for refrigerating and heating

Abstract

The invention belongs to the technical field of air conditioning devices, and particularly relates to a central fresh air purification system for refrigerating and heating. By arranging an air distribution device, fresh air can be refrigerated, heated, filtered, purified and deodorized in multiple rooms, the longest air supply distance can reach 30 meters, the air volume is not attenuated, and centralized control can be achieved. Only one layer of glass fiber filter and one layer of multifunctional filter are arranged for fresh air purification and peculiar smell removal, purification indexes can be achieved, the structure of a purification outdoor unit is simplified, the replacement frequency of filter materials is reduced, wind resistance is reduced, and the fresh air throughput is increased. A wave-shaped white steel wire mesh primary filter is adopted, so that the filtering area is increased, the filter can be cleaned, and the replacement period is prolonged. A double-layer white steel plate turbine cover filled with the foaming agent in the middle is arranged, the water filtering holes are formed in the bottom, and the problem that equipment breaks down due to the influence of cold and warm air is solved. In addition, the system is rigorous in structure, reasonable in design and suitable for popularization and application to the society.

Description

technical field [0001] The invention belongs to the technical field of air conditioning devices, and in particular relates to a central fresh air purification system for cooling and heating. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for their surrounding environment, and they all hope that the air around them is clean and safe. However, with the development of the economy, the air environment is deteriorating, and people are constantly troubled by smog weather. The three items of sulfur dioxide, nitrogen oxides, and inhalable particulate matter are the main components of smog. The harmful particles in the air contain various harmful substances. There are more than 20 kinds of fine particles and toxic substances that are harmful to the human body. If you live and work in an environment with poor air quality for a long time, it will lead to the decline of respiratory function and the occurrence o...

However, with the development of the economy, the air environment is deteriorating, and people are constantly troubled by smog weather. The three items of sulfur dioxide, nitrogen oxides, and inhalable particulate matter are the main components of smog. The harmful particles in the air contain various harmful substances. There are more than 20 kinds of fine particles and toxic substances that are harmful to the human body. If you live and work in an environment with poor air quality for a long time, it will lead to the decline of respiratory function and the occurrence of respiratory diseases, which will endanger life

In addition, the residual formaldehyde in interior decoration now exceeds the standard, which has an impact on the living environment, so the use of fresh air purification equipment is becoming more and more popular among consumers

However, the traditional purification equipment only purifies and filters the space, and cannot reduce the concentration of formaldehyde at the same time, and can also adjust the air temperature.

[0003] In the existing technology, some of the fresh air is only cooled, heated, filtered and purified for one room alone, and the central control of multiple rooms cannot be realized. Moreover, the filters in the existing equipment need to be multi-layered or affected by the material. The life of the material is short, which increases the frequency of replacement, and the fan of the equipment is prone to failure due to the influence of cold and warm air
