hotels are the first choice for many urbanites, whether they are gathering friends, having family dinners or entertaining guests. When going out, the hotel is also a good temporary residence. Compared with ordinary hotels and restaurants, hotels belong to high-end consumption occasions and require higher environmental comfort. Therefore, when many hotels are renovated, the hotel fresh air system becomes the first choice. As a dark horse of hotel ventilation equipment, the fresh air system of Aipinsheng Hotel can bring practical benefits to different places in the hotel. \x1d\ Features of hotel fresh air system \x1d\ The main reason why people choose hotels is that they have a good dining and rest environment and high comfort. Nowadays, there are more and more hotels in the city, and the competition between them is getting higher and higher. When choosing hotels, many people not only pay attention to the price and service, but also the quality of their environment has become an important standard. Hotels that have installed the fresh air system of the hotel have obviously better environmental quality and are more attractive to customers. \x1d\ On the other hand, the hotel environment is generally closed. When dining, there are many people indoors. If ventilation is not done well, the smell of alcohol and smoke in the room cannot be treated, and the comfort is poor. When the hotel fresh air system is installed, the odor and turbid air in the room can be directly discharged to the outside, ensuring better indoor air quality. \x1d\ The fresh air system of Aipinsheng Hotel is designed according to the functions of the hotel \x1d\ Generally speaking, the hotel mainly has two functions, namely catering and accommodation, and their requirements are quite different. However, the fresh air system series developed by Aipinsheng in Germany can be perfectly applied to all major hotels. \x1d\ One: As a dinner party, the hotel box has a small space and a large number of people, so the indoor air is turbid. In this case, the main function of the hotel fresh air system is to ventilate, exhaust the indoor turbid air as much as possible, and introduce a lot of fresh air to dilute and purify the smoke and alcohol in the room, so a high-power ventilator is needed. Aipinsheng E9, EC, EA hotel fresh air system, with from 181m? /h to 5111m? /h, loaded with H13 medical grade Hepa filter, can effectively purify outdoor fresh air and indoor smoke and alcohol. \x1d\ Secondly, the hotel rooms are used for accommodation, and the flow of people is relatively small, so the demand for indoor ventilation is low. As a resting place, guest rooms require more comfort and tranquility. Therefore, the fresh air system requires oxygen delivery and silence to ensure that indoor comfort and customers' rest and sleep will not be affected. The fresh air system of Aipinsheng Hotel in Germany can work continuously for 24 hours, constantly supplying suitable oxygen to the room. The fresh air system of the hotel operates with the highest running noise of 48db and high efficiency, creating a quiet and comfortable rest environment for hotel guests. As other auxiliary facilities of the hotel, leisure places such as cinema, chess room, KTV, etc., due to the large flow of people, the requirements for fresh air can not be ignored, and the impact of smoke, human waste gas and sharply rising CO2 concentration on customers is also quite severe. The fresh air system from iPeson Hotel in Germany has strong air volume, which can purify thousands of square meters of activity space; With H13 medical grade Hepa filter and ultraviolet sterilization function, it still has zero tolerance for PM2.5, formaldehyde, odor and virus in the air. \x1d\ Aipinsheng fresh air system is extended to Germany's "German Industry 4.1", and the exquisite and environmentally friendly alloy material is durable, which further embodies the mechanical extension of German craftsman spirit. Scientific aerodynamics principle can effectively solve the problems of secondary pollution, air channeling and air leakage caused by bacterial growth in pipes of fresh air systems of other brands in the market.
