Central ventilation system

Abstract

The invention discloses a central ventilation system. The central ventilation system comprises an intake channel; a fan is arranged in the intake channel; a filter screen is arranged in an intake port of the intake channel; an exhaust port of the intake channel respectively penetrates through and is connected with an exhaust channel 1 and an exhaust channel 2; an exhaust port end of the exhaust channel 1 is connected with a filter device 1 and an electronic air purifying device in sequence; an exhaust port end of the exhaust channel 2 is connected with a filter device 2; the tail ends of exhaust ports of the exhaust channel 1 and the exhaust channel 2 respectively penetrate through and are connected with the exhaust channels; and the exhaust channels are connected with humidifying devices, negative oxygen ion generation devices and electric heating devices in sequence. A detecting device is adopted to detect impurity components in air; the channels are automatically divided for distinguished processing, so that the air purifying efficiency and quality are improved, meanwhile, the electric power resource waste is prevented, and green environmental protecting requirements of energy conservation and emission reduction are accorded with; and meanwhile, humidification, heating and increment of negative oxygen ion components can be selectively performed to provide air more beneficial to the body health.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, in particular to a fresh air system. Background technique [0002] With the rapid development of industrial society and the gradual improvement of people's living standards, air quality is increasingly concerned by everyone, especially the increasing air pollution and the extensive use of interior decoration materials, how to purify people's lives, work and other spaces. Air quality has increasingly become a topic worthy of research and discussion. At present, there are many factors that affect indoor air pollution in people's living and office, including harmful gas or odor pollution caused by excessive decoration and the use of inferior materials, as well as impurities such as dust, heavy metals, and inhalable particles caused by rain in the air quality. Pollution also includes hair, bacteria, dust, organic gas or allergens in special environments. For the same indoor space,...
