1、總述 General Description
LF型光管加熱器在空調(diào)系統(tǒng)中對(duì)空氣進(jìn)行預(yù)處理和再處理?？諝獗凰幚砬坝霉夤芗訜崞鬟M(jìn)行加熱，則為預(yù)熱器，以提高空氣溫度，提高加濕能力?？諝獗凰幚砗笥霉夤芗訜崞鬟M(jìn)行加熱，則為再熱器，以補(bǔ)償車間熱量的不足。
光管加熱器可以串聯(lián)或并聯(lián)安裝。當(dāng)被加熱的空氣量少而要求溫升高，可采用串聯(lián)形式，反之則可采用并聯(lián)形式。
光管加熱器主管為φ108×3，散熱管為φ27×2.5，用均采用無縫鋼管焊制而成，出廠時(shí)經(jīng)嚴(yán)格的壓力試驗(yàn)，安全可靠。
LF model plain pipe heater is used in air conditioning system for air pre and re-heating treatment. Air is heated by plain pipe heater before water treatment. Plain pipe plays the role of pre-heater to improve air temperature and humidifying ability. When plain pipe is applied after water air treatment, it plays the role of re-heater to compensate heat shortage in plant.
LF model plain pipe heater can be installed in series or parallel connections. When air capacity is low, series connection is applied,. Otherwise, parallel connection can be applied.
Plain pipe heater is welded by seamless steel tube, pressure test of which has been taken to ensure safety and reliability. Diameter of the main pipe isφ108×3, radiating pipeφ27×2.5.
