变频空调应该抽真空

变频空调应该抽真空 变频空调抽真空操作程序 三分空调七分安 最近在搞装修，给买变频空调的同学们提个醒，安装的时候一定要抽真空。看外地的90%是排气式安装的，就是扭开阀门放点气，正确的应该是用真空泵抽上30分钟，否则空调容易坏掉。我建议是 :宁愿多给师傅点钱 ，也得抽真空。就算是抽真空，里面的猫腻也多了去了，很多操作工只带真空泵，不带压力表，这种抽法，只有上帝知道真空了没。塞个几十块小费吧，总比制冷效果差，搞不好还要重新加制冷剂要好。 抽真空的六大步骤: 1.先没收安装工人的内六角板手。 2.将连接内外机的管道接好,上紧。 3.在气管(粗管)三通阀修理口接上压力表连接真空泵,先开真空泵后再打开压力表阀门,抽真空开始后将压力抽置负0.1MPA,再抽15-20分钟,以压力表负压值为准。 4.先关闭压力表阀门,再关闭真空泵。看压力表,观察压力是否回升。 5.归还内六角板手用来打开液管阀(细管二通阀,,,圈),约10秒后关闭,用检漏枪或quality egg, chicken, ... Development of poultry industry will occupy a certain area of land, there is a modern product with comprehensive rollup of 50,000 chickens laying hens, covers an area of 14.87 hectares (233 acres) more (including Office of hatching, brood rearing, and laying House, eggs, feed processing workshop, Office, etc). The poultry industry should work in land conservation, not accounted for or less cultivated land, wasteland, the principle of slope land. When the chicken farm should generally not available to local arable land area to determine an appropriate level of breeding size and not, as in the past, first determine the size, then go to the expropriation. 3. energy-saving, water-saving awareness in the 1970 of the 20th century, the pig and chicken farm mechanization in our country forward under the slogan, the country started building a modern large chicken farms in the climax. Was built as the fully enclosed intensive chicken farms, using artificial light, mechanical feeding and mandatory ventilation, a small number of chicken farms also use mechanical sets eggs and manure. According to statistics, fully enclosed chicken coop per chicken when the annual electricity consumption of 10-kilowatt •, half opened the henhouse when • 2~5 kW (open), when the entire opening is 0.5 kW •, rolling open sheds at 0.45 kW •. Hen house types, power consumption difference is very big, a difference of 10~20. China's energy supply is in short supply. Therefore, in determining the breeding, poultry equipment selection should take full consideration of energy saving issues. Lack of fresh water resources in China, the average annual precipitation is 600 mm. 1988 2474 cubic meters of water per capita in China, only 1/4 of the population all over the world, now reduced to 2300 cubic meters.
