What is a clean air conditioner?
Purification air conditioning, as its name implies, is an air conditioner with purification function. Mainly used in pharmacy, chemistry, hospital operating room, negative pressure ward, animal room, medical equipment, food and beverage, aseptic laboratory, P-level experiment, GMP clean aseptic operating room, negative pressure ward, laminar flow ward, GMP purification workshop, electronic dust-free workshop, beverage filling workshop, QS food purification workshop, purified water filling workshop, constant temperature and humidity laboratory, dust removal workshop, gravity flat floor, LG coil floor, aseptic filling workshop and purified air conditioning unit. So as to keep the indoor air in a good environment.
What is the principle of purifying air conditioning?
The principle of purifying air conditioning is summarized as "three defenses and one division". Prevent dust from directly invading the room, prevent particle accumulation, try to prevent the occurrence of particles, and effectively and quickly eliminate dust particles occurring indoors. Clean air conditioning system is a new technology born to meet the requirements of precision, miniaturization, high purity, high quality and high reliability in experimental research and product processing. It is widely used in aerospace, precision processing, fine chemical industry, hospital operating department, electronics industry, pharmaceutical industry, food industry and other fields.
What's the difference between clean air conditioning and ordinary air conditioning?
1, main parameter control. General air conditioning focuses on the control of temperature, humidity, fresh air volume and noise, while clean air conditioning focuses on the control of indoor air dust content, wind speed and air exchange times. In rooms with temperature and humidity requirements, temperature and humidity are also the main control parameters. For biological clean room, bacterial content is one of the main control parameters.
2, air filtration means. Generally speaking, some air conditioners only have coarse-effect primary filtration, and the higher requirement is coarse-effect medium-effect secondary filtration. Clean air conditioning requires three levels of filtration, namely coarse, medium and high efficiency filtration, or coarse, medium and secondary high efficiency filtration. In addition to the three-stage filtration in the air supply system, in order to eliminate the special smell of animals and avoid environmental pollution, the air exhaust system is equipped with two-stage efficient filtration or toxic adsorption filtration according to different situations.
3. Indoor pressure requirements. General air conditioners are not strict about indoor pressure. In order to avoid the infiltration of polluted air or the interaction of different substances in different workshops, the requirements of clean air conditioning for positive pressure in different clean areas are different. Negative pressure clean room still has requirements for negative pressure control.
4. In order to avoid being polluted by the outside world, there are special requirements for the selection of materials and equipment, processing technology, processing and installation environment and storage environment of equipment parts. This is different from the general air conditioning system.
5. Air tightness requirements. Although the general air conditioning system requires air tightness and air leakage, the requirements of clean air conditioning system are much higher than those of general air conditioning system, and there are strict measures and requirements for the testing methods and standards of each process.
6, civil engineering and other types of work requirements. General air-conditioned rooms have requirements on building layout and thermal engineering, but they are not very strict on material selection and air tightness. Besides the appearance requirements of general buildings, the evaluation of clean air conditioning on building quality focuses on dust prevention, dust prevention and leakage prevention. In the construction process, the layout and connection requirements are very strict to avoid cracks and leakage. It is also very strict with other types of work, mainly to prevent leakage, prevent external pollution air from infiltrating into the clean room and prevent dust from polluting the clean room.
