Suction fan exhaust air out the room pressure drop, indoor air thinned to form a negative pressure zone farming fans, air flows into the interior of compensation due to the pressure difference. In practical applications, industrial plants, centralized suction fan installed in the plant side air intakes in the plant room on the other side, the air intake by mouth suction fan convection hair. In this process, the suction fan near the doors remain closed, forcing air to flow from the air inlet side shop windows compensation. ※ set ventilation, ventilation and cooling in one. ※ energy: low power consumption, only about 10-15% of traditional air conditioning. ※ environmental protection: no Freon (CFC). ※ good cooling effect: the outside air through the cooling water showering after entering the room, the cool side curtain indoor temperature can reach 5-10 degrees of cooling effect. ※ high return on investment, payback costs 2-3 years. ※ quickly muddy farming radiator fan, hot and smelly replace exhausted to the outside air indoors. ※ effective control of the indoor environment, indoor produce different wind speeds, resulting in cool effect, it is unusual to feel comfortable and fresh. ※ reduce infectious diseases, such as influenza and effective prevention of sudden large-scale spread of the virus. Birds, mosquito breeding FRP fans, flies are vector-borne diseases due to water POON negative pressure ventilation system is closed, will reduce vectors propagation probability, will allow staff to work in a comfortable safe and secure environment.
