As we all know, the role of PP fume hoods in the laboratory is pivotal, but at the same time there is a troubling problem: that is, the fume hood's energy consumption is very large! This our country in recent years to promote energy saving emission reduction, to achieve the concept of sustainable development is in conflict with each other, laboratory fume hood energy consumption deserves your close attention. A common fume hood working 8-10 hours a day if 24 hours, every hour will be discharged to the outside 1200-1500 cubic meters of laboratory air. Laboratories must be equipped with air conditioning systems to ensure constant temperature humidity in the laboratory to ensure the accuracy of the experiment, but the air conditioning by the production of cold warm air is often easily discharged by the piping system to the outside. The average loss of each fume hood is about 17,000 RMB per year.

In addition, externally vented PP safety cabinets can also cause direct indirect damage to the ecosystem. The direct damage is due to the fact that residential areas office buildings near many laboratories are often subjected to pollution by chemical exhaust fume hood ducts. Indirectly, the main source of energy for power generation in China is coal. A study in the United States showed that the energy consumption of laboratory fume hoods (about 7.5 million in the United States, roughly the same number as in China) is equivalent to the energy generated by at least 12 250 megawatt power plants, which burn coal to generate electricity, releasing sulfur dioxide (producing acid rain) carbon dioxide (creating a greenhouse effect).

One solution is to reduce the volume of air discharged out of the fume hood. This can be done with the help of a VAV system (Variable Air Volume), but the installation of a VAV system is very complex expensive, it takes a long time to recoup the cost of the installation through the energy savings it brings. Importantly, the VAV system will lose its energy savings if the lab personnel do develop good habits to pay attention to the door opening height. Another solution is the use of ductless fume hoods. This type of fume hood is equipped with an activated charcoal filter that adsorbs chemical gases generated during operation, once filtered, clean air is circulated in the room instead of being exhausted outside. It has two outstanding advantages: firstly, it does exhaust indoor air, thus saving a lot of energy consumption; secondly, it does pollute the environment. In addition, its flexibility is outstanding. It only requires an electrical outlet can be placed in any location in the laboratory. Based on the outstanding features of the ductless air purification type fume hood, it will become the main protection tool for chemical operations in future chemical laboratories.

What kind of clean-air fume hood Shanghai Shower Tower is safe? People with a certain knowledge of chemistry know that the life of a filter depends on the type of chemical it adsorbs the volatility of the corresponding chemical, but also the environment in which the filter is located, such as temperature humidity will have an impact. So can be generalized that the life of the filter is a year, which raises a very critical issue, how to accurately determine the time of saturation of the filter, because if the filter is saturated the end of the timely detection detection, will immediately lead to insecurity the safe, so the production-oriented enterprises must highlight the on-line monitoring system to accurately inform the customer in a timely manner.

Therefore, in order to realize the purpose of energy saving safety at the same time, the clean air type fume hood is a good choice. Moreover, the net gas type fume hood can ensure the safety of experiments experimental personnel, but also to achieve the purpose of energy saving emission reduction, fish bear paw both, why ?
