. Q2 composition and principles of Panasonic's new wind system can tell us about it A:? Panasonic unidirectional flow of fresh air ventilation system consists of a host (or porous silent fan blower), duct, air vents, natural inlets and other accessories. When the host running, outdoor fresh air from natural new outlet introduced under pressure field effect host formation, to the indoor activity area, meet the needs of staff activities, after which polluted air through the exhaust port, exhaust Road to Outdoor. Airflow scientific and rational manner, continuous low air flow design, runtime power consumption, low noise, and to ensure indoor air quality. Panasonic bi-directional flow of fresh air system consists of a host (host full heat recovery heat exchangers, with or without heat recovery feature bi-directional flow of new fans), air pipes, exhaust pipes, air diffuser, air vents and other accessories. When the host running, the introduction of fresh air from the outside, sent to each room through the air duct; polluted air exhausted to the outside through the exhaust duct from the host. After the host and the fresh air ventilation in progress (for the whole heat exchanger) exchange heat recovery, recycling most of the energy back to the interior through the new wind. . Q3 with a ventilation fan do not realize it can also be why fresh air ventilation system A:?? Exhaust fan only a short time to achieve partial exhaust air system, no sound pressure field organization and flow path, and therefore can not achieve a real sense of air displacement. Also, the fan does not run continuously 24 hours, noisy fan. To achieve high-quality air in the true sense of displacement, the system must be professional job hazards of benzene and BTEX new home decoration pollution brings disease 3:! * Chronic benzene poisoning mainly on the skin, eyes and benzene respiratory tract irritation. Regular contact with benzene, and the skin may become dry due to degreasing, scaling haze nemesis air system, and some appear atopic eczema. Long-term inhalation of benzene can cause aplastic anemia, and the emergence of neurasthenia, manifested as dizziness, insomnia, fatigue, memory loss, thinking and judgment to reduce other symptoms. After leukopenia and thrombocytopenia, severe bone marrow skills disorders can occur, leading to aplastic anemia. If the hematopoietic function completely destroyed Townsend fresh air system, can be fatal leukocyte granules disappear disease, and can lead to leukemia. In recent years a lot of Occupational Health data show that: long-term exposure of workers benzene mixture aplastic anemia prevalence is higher. Benzene can cause birth defects as toluene and xylene is a major role fetal central nervous system damage. · Toluene in circumstances such as repeated exposure to nasal inhalation will suffer permanent brain and kidney damage. If the mother is exposed during pregnancy seriously, toxicity may affect the infant and defects. · Xylene can cause dry skin, nervous system damage Panasonic air system, it will result in temporary kidney and liver damage. Research shows that women are more susceptible than men to benzene, have a certain influence, toluene, xylene, reproductive function, women of childbearing age long-term inhalation of benzene can also cause menstrual abnormalities, mainly as menorrhagia or disorder, initially often due to menorrhagia or menstrual bleeding between periods and medical treatment, is often misdiagnosed and delayed treatment for bleeding within functional habits. Experts Statistics found that the rate of spontaneous abortion exposure to toluene laboratory staff and workers was significantly higher. Radon hazards: High concentrations of radon can cause the body's blood cells change. Radon has a high affinity for body fat, especially after radon combined with the nervous system, more dangerous.
