A designer has done an interesting experiment. By combining with a microcomputer, the plant can also be a B-box.
The designer used a Raspberry Pi microcomputer and installed a touch sensor and speaker on the root of the vegetable. The Raspberry Pi circuit was used for signal conversion processing. A drum set with a vegetable root as the sensing medium was created. Every vegetable root produces different pitched drums and buzzing sounds. He named it B-box. B-Box is used to let people experience the difference between sense and cognition. The designer stated that he likes to interact with complex technological aspects in his work, but on the surface he cannot see it at all. Take this work as an example, its interaction with the audience is very simple. Although it is an electronic product, there is absolutely no trace of electronic components in appearance. The B-Box works by using a touch sensor to record the input signal that touches the vegetable root. Then, a Python script on the Raspberry Pi microcomputer receives the signal and converts it into an output signal, which drives the loudspeaker hidden under the box. Drum sounds from the speakers.
B-Box uses organic materials. Vegetable roots will spoil sooner or later, so they can only be watched for a short period of time and have no commercial value.
Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
