The Studying Of In Door Air Qualiquty Controlling Equipment Of Toll Gate

With the developing of the economy, the number of car in our country is becoming more and more. Therefore, automobile off-gas has a lot of negative effect on the environment. The environment near the tollbooth becomes more serious. The health of the staff in the tollbooth is seriously endangered. To improve air quality,establishing comfort and health environment indoor to improving the work efficiency,we excogitate the indoor air quality controlling equipment of tollbooth, with it, at the same time, we can save energy in using and control air quality in tollbooth.In this paper, we have successful excogitated the device, which on the base that we have not only analyzed the pollution around of the tollbooth, but also know about the rule of distributing and diffusing of the pollution. Besides that personal ventilation technology have used in the equipment, with which fresh air can be sent to the tollbooth. During the action, not only the temperature of the air, but also the amount of fresh air and the angle of sending it can be adjusted freely. We have studied the equipment farther more, such as the testing that whether the accumulator is reasonable for the water in it and parameter of the fresh air is according with design etc. With the data of test, we can give a conclusion that the equipment achieved the aim improving the indoor air quality completely. We set the equipment in the tollbooth testing the effect result, from this we can give a conclusion that the equipment can not transporting fresh air setting up comfortable environment according with user and also keeping the tollbooth in the state which the air pressure in the tollbooth is a little higher than it out of tollbooth. In this state, the pollution out of the tollbooth can be prevented from entering from the window.The results show that the indoor air quality controlling device in the highway tollbooth can satisfy the design requirements on the temperature control, humidity control, the volume of fresh air control, the comfort of air supply and so on. It can effectively control the indoor air quality and improve the working environment of the staff.
