Air adjustment is a technique that enables parameters such as the temperature, relative humidity, clean degree, and airflow speed of the room or closed space. That is, in people's lives and work, the temperature, humidity, clean degree, and airflow velocity of the ambient air in a certain space of production and research constitute the air environment of the space. Take the necessary technical means to create and maintain the air environment required in this space is the task of air conditioning. In the air conditioning system, the air treatment device is an air conditioner is a core portion that realizes air heat, wet exchange, and air filter purification. A room or a space, in general, in addition to a serving structure from the interior of the room, people, lighting, particles, microbes, or other hazardous interference, and outside of the room Interference of atmosphere, solar radiation, etc. In order to eliminate the above-mentioned interference from indoor and outdoor,

1. The basic knowledge of the filter is the main purification device of the clean room, which is the main means of air purification. Therefore, it is very important for the basic knowledge of clean room design, construction, and maintenance management to understand and master the filter. A. The classification of the filter is divided according to the performance of the filter (efficiency, resistance, dust removal), usually divides it into a coarse, alive, high-efficient, sub-efficient, efficient (HEPA) and ultra efficient (ULPA) Six types of filters.

Air-conditioning filters are not as simple as unplugging the power source. In the hot summer, people laugh at\"Life is given by air-conditioning\". The air conditioner that has been working is really\"difficult\", but with the advent of comfortable weather, the air conditioner at home will be\"broken\". It is not as simple as cleaning the power supply.

Nowadays, when the quality of life continues to improve, we not only pursue the quality of life in terms of family life and working environment, but also adopt some air filters to reduce pollution and ensure the comfort of the working environment. The office is not an ordinary place, but a place where many workers work.

Under normal circumstances, the frequency of cleaning the filter, and then promptly inform the filter environment. For example, whether the temperature of the high-efficiency filter components is high, whether the filter medium itself is corrosive, and whether the filter strength is high, so that personnel can comprehensively evaluate the data and data to determine the basic airbag type. The frequency of filter cleaning is used as the basis for the post-development filter cleaning program.
