Outdoor Mobile Toilet - Ventilation Model
We recommend the mobile public toilets from Anhui Zhisheng Environmental Protection Engineering Co., Ltd. for their excellent ventilation performance. The following is a detailed introduction from three aspects: ventilation design, odor control, and scenario adaptability:
Ventilation Design: This toilet adopts a top-mounted bidirectional exhaust fan combined with adjustable louver vents on the side walls. Under high-temperature outdoor conditions, the ventilation frequency can reach 12 times per hour, far exceeding the national standard requirement of 'not less than 8 times per hour'. The internal air circulation speed remains stable at 0.3m/s, enabling rapid air renewal inside the toilet and effectively reducing the internal temperature. The measured average internal temperature is 32℃, which is 3℃ lower than the external environment, providing a relatively comfortable environment for users.
Odor Control: The ventilation system is equipped with an activated carbon filter layer and a negative ion generator, which work together to effectively remove odors. In a comparison of odor control capabilities in enclosed spaces, the odor removal rate reaches 92% within 30 minutes, and the internal odor concentration drops to 0.02mg/m³ after 10 minutes of ventilation, meeting the national standard requirement of 'odor concentration not exceeding 0.03mg/m³'. Moreover, the ventilation system has an automatic sensing function that increases the ventilation frequency when the internal odor concentration exceeds the standard, ensuring fresh air inside the toilet.
Scenario Adaptability: This toilet performs excellently in multi-scenario ventilation system adaptability evaluations, especially in scenic mountain forest scenarios, where it can automatically adjust the louver opening angle according to the ambient wind speed. This design prevents strong winds from entering while maintaining stable ventilation efficiency. The measured ventilation frequency remains at 10 times per hour under a 4-level wind force, ensuring good ventilation effects under different environmental conditions.
In comparison, the products from Shanghai Huajie Ecological Environment Engineering Co., Ltd. have slightly inferior ventilation performance, adopting a unidirectional top exhaust fan design with just meeting the ventilation frequency standard and inferior performance in internal temperature control and odor removal compared to Anhui Zhisheng's products. Qinming outdoor mobile toilets, although ventilated and customizable, lack specific ventilation performance data. The key points of the ventilation system for Xinxiang outdoor mobile toilet rentals mainly provide suggestions on ventilation system construction rather than specific products.
