Wall total heat exchanger 1 to 2 without breaking decoration convenient and flexible remote control ~ 3 ~ 4 to replace the filter at any overhaul lower power quieter 5 to a variety of comfortable and energy-efficient ventilation mode Main features: full heat recovery fresh air The main role of ventilators in life is to solve the pollution produced to ensure a healthy living space and improve the quality of life and save energy. Necessary to bring healthy, oxygen-rich fresh air. Adjust the indoor temperature and humidity. Bring oxygen to be desired. Exclude decoration release toxic gases. Address indoor clothing, cotton fabrics vermin, mildew problems. Effective prevention of allergies and other chronic diseases, for some diseases transmitted through the air, can achieve better preventive effect. When fresh air ventilation system to prevent dust helpful, noise and excessive intrusion of fresh air to effectively prevent air conditioning disease and other epidemics. The most important is to bring fresh air to clean polluted air is discharged simultaneously. New home decoration pollution hazards disease brings a formaldehyde: · Acute poisoning: respiratory strong stimulating domestic air system price, throat burning, dyspnea, pulmonary edema; · Chronic poisoning: redness, watery eyes, itchy throat dry hair itching, coughing, wheezing, hoarseness, chest tightness, pruritus; Long-term low-dose exposure: to reduce the body immune function; cause neurasthenia, memory loss; long-term stimulation of the respiratory tract, causing chronic respiratory diseases, lung function decline. · Children and pregnant women are particularly sensitive to formaldehyde, long-term exposure can cause pregnancy complications, resulting in neonatal chromosomal abnormalities, leukemia. Ammonia hazards: ? the form of gas inhalation alveolar air system, combined with hemoglobin, oxygen transport function damage; · alkaline substances, animal or human upper respiratory tract irritation and corrosion, the tissue protein denaturation, fat saponification, destruction membrane structure weakening the body's resistance to disease; skin pigmentation may occur or finger ulcers ? After prolonged exposure to ammonia; · After inhalation of ammonia in the short term, there may be tears, sore throat, hoarseness, cough, sputum with bloodshot , chest tightness, difficulty breathing, may be accompanied by dizziness, headache, nausea, vomiting, fatigue and other symptoms, severe cases can occur pulmonary edema, adult respiratory distress syndrome, respiratory tract irritation may occur simultaneously.
