汽车空调原理

HEALTH ALERT !!! Please TAKE Note and Circulate... Do not turn on A/C immediately as soon as you enter the car! 上车后不要立刻开空调！ Please open the windows after you enter your car and do not turn ON the air-conditioning immediately. According to a research done, the car dashboard, sofa, air freshener emits Benzene, a Cancer causing toxin (carcinogen- take note of the heated plastic smell in your car). In addition to causing cancer, it poisons your bones, causes anemia, and reduces white blood cells. Prolonged exposure will cause Leukemia, increasing the risk o f cancer may also cause miscarriage. 上车后先打开所有车窗，不要立刻开空调。研究发现，车内的仪表板、沙发、空气清新剂会散发出致癌性物质－－苯（注意车内塑料受热后发出的气味）。除致癌外，苯还会毒害骨骼、引起贫血、减少白血球。长期接触苯可导致白血病，增加患癌风险，也会导致孕妇流产。 Acceptable Benzene level indoors is 50 mg per sq. ft. A car parked indoors with the windows closed will contain 400-800 mg of Benzene. If parked outdoors under the sun at a temperature above 60 degrees F, the Benzene level goes up to 2000-4000 mg, 40 times the acceptable level... & the people inside the car will inevitably inhale an excess amount of the toxins. 停放在室内的汽车，在车窗关闭的情况下，车内含苯量在400-800毫克。停放在室外的汽车，经过阳光暴晒后，车内温度可达到60oF,这时车内苯浓度高达2000-4000毫克，为容许浓度的40倍。人在车内，就会不可避免地吸入过量的毒物。 It is recommended that you open the windows and door to give time for the interior to air out before you enter. Benzene is a toxin that affects your kidney and liver, and is very difficult for your body to expel this toxic stuff. 建议上车前，先打开车窗和车门，让车内的气体排出。苯是一种有毒物质，会损害肾、肝。一旦吸入，很难从体内排出。 "When someone shares something of value with you and you benefit from it, you have a moral obligation to share it with others"
