Job prospects for heating, air-conditioning, and refrigeration mechanics and installers are expected to be good, particularly for those With technical school or formal apprenticeship training.
The Air-Conditioning Excellence program, offered through North AmericanTechnician Excellence, is the standard for certification of experienced technicians.
What Would those living in Chicago do Without heating, those in Miami do refrigeration? Heating and air-conditioning systems control the temperature, humidity, and the total air quality in residential, commercial, industrial, and other buildings. Refrigeration systems make it possible to store and transport food, medicine, and other perishable items. Heating, air-conditioning, and refrigeration mechanics and installers—also called technicians—install, maintain, and repair such systems. Because heating, ventilation, air-conditioning, and refrigeration systems often are referred to as HVACR
暖氣、空調(diào)和冷凍技術(shù)工人和安裝工人的就業(yè)前景一直都被看好，特別是對(duì)那些具有技術(shù)學(xué)校和受正規(guī)學(xué)徒訓(xùn)練的人來(lái)說(shuō)更是如此。
由北美優(yōu)秀技術(shù)人員組織提供的空調(diào)技術(shù)卓越計(jì)劃已經(jīng)作為技術(shù)人員是否有經(jīng)驗(yàn)的衡量標(biāo)準(zhǔn)。
設(shè)想那些生活在芝加哥的人沒(méi)有暖氣怎么辦，生活在邁阿密的人沒(méi)有空調(diào)怎么辦，或者全國(guó)各地的血庫(kù)沒(méi)有冷凍技術(shù)怎么辦？暖氣和空調(diào)系統(tǒng)控制著溫度、濕度和整個(gè)居住區(qū)、商業(yè)區(qū)、工業(yè)區(qū)及其他建筑物內(nèi)的空氣質(zhì)量。 冷凍系統(tǒng)使儲(chǔ)存和運(yùn)輸事物、醫(yī)藥和其他易變質(zhì)的東西成為可能。暖氣、空調(diào)和冷凍技術(shù)工人和安裝人員—也就是所謂的技術(shù)人員---負(fù)責(zé)安裝、保養(yǎng)和維修這些系統(tǒng)。由于暖氣、通風(fēng)、空調(diào)和冷凍系統(tǒng)經(jīng)常被稱為HVACR系統(tǒng)，這些工人也因此可被叫做HVACR技術(shù)人員。
