For the first method , each house has a separate refrigerating unit , freon as the refrigerant evaporates in the cooler to cool the air . the unit is controlled with the set temperature 氟利昂單機單控方式是指每個冷庫的制冷系統由一套或兩套獨立的氟利昂制冷機和冷風機組成,根據溫度控制其自動開停,由氟利昂直接在冷風機內蒸發來降溫。

Thick insulation , high - efficiency and energy - efficient use of environmentally friendly freon - free polyurethane foam insulation layer of thick , significantly reduce heat loss , better insulating effect , more efficient energy expenditure 管道選用的是抗腐蝕性高,保溫性好的ppr管,使得管道有很好的使用效果和較長的使用壽命。

Abstract : this paper deals with the earth environmental protection related to the destruction of the ozonosphere by freon from people ' s daily life , and human ' s active measures to meet this attack 文摘:綜述了與百姓生活密切相關的氟里昂對臭氧層的破壞所帶來的全球性的環境保護問題以及人類對這一問題的積極應戰。

Mark : all center . this morning i took my car to the garage tohavethem check the air - conditioner . they only gave it aonce - over , refilled it with some freon , and charged me 300bucks 馬克:好吧。我今天早上去修車廠修車里的空調,他們就隨便看了一下,加了點氟利昂,就要我300塊錢!

The cfcs were once considered harmless and used extensively in spray cans , cleaners for electronic and optical components , foaming agents , styrofoam , and freon 曾被公認是無害的cfc ,被廣泛的運用各在各種產品上,例如,噴霧器電子零件及光學零件清洗劑發泡劑保麗及冷媒。

Two refrigeration methods are commonly used in cold storage warehouse : direct cooling of one unit to one house with freon , indirect cooling with glycol 以往的冷庫中冷源有兩種方式,一種是氟利昂機組單機對單個冷庫直接制冷方式,一種是乙二醇間接制冷方式。

It also supplies liquid oxygen , liquid nitrogen , acetylene , carbon dioxide , hydrogen , propane , freon , liquid ammonia , and rare element gas 還兼營液氧、液氮、液氬、乙炔氣、二氧化碳、氫氣、丙烷氣、氟里昂、液氨及其他高純和稀有氣體。
