Ventilation and cooling engineering company analyzes several common indoor ventilation methods brought by ventilation


1. Ventilation and cooling engineering company analyzes blindly opening windows. The direction of ventilation airflow is unstable. You can smell the living room and bedroom of the bathroom and kitchen. Outdoor dust blows into the room, noise pollution, and windows will cause a lot of energy waste when using air conditioning.

2. The ventilating window cannot be opened during the rainy season, and the room is prone to mildew, and the odor cannot be ruled out. When opening and closing, the ventilation is discontinuous. Only part of the area that addresses local ventilation, the case of imported fresh air, poor exhaust.

3, negative ion generator, air purifier, only the original indoor air treatment, indoor air pollution increased, processing capacity. Can not provide fresh oxygen-enriched air, indoor air floating treatment, dust and other harmful substances adsorbed by air purifiers, but not harmful molecules adsorbed gas.

4. A small amount of fresh air from the domestic central air conditioner enters, but there are no vents, and the air that does not significantly improve indoor air pollution cannot be quickly exhausted to the outside, only the wind, then the indoor pressure, so that outdoor fresh air enters the room It is not easy to make the room between the body and the air conditioning unit to form a closed circuit system. Only by adjusting the temperature, the air quality cannot fundamentally solve the problem; it is brought back to the vent, but it cannot be exchanged with outdoor air. Without ventilation, the new air pressure zone has become difficult to feed. Contaminated air cannot be moved outdoors quickly. It's just cold, hot, fresh air, and ventilation can't solve the problem.
