精密空調(diào)的顯熱比為，*0%~20%是用于除濕，基站空調(diào)養(yǎng)護(hù)。因此，在處理相同顯熱負(fù)載的情況下，“標(biāo)稱”20冷噸的舒適性空調(diào)所需數(shù)量要多于精密空調(diào)。精密空調(diào)主要為主設(shè)備提供全年不間斷制冷，精密濕度控制，和比舒適性空調(diào)更高的制冷能力/平方英尺，基站空調(diào)養(yǎng)護(hù)。精密空調(diào)與舒適性空調(diào)對(duì)比1.優(yōu)化制冷以滿足電子系統(tǒng)要求電子設(shè)備比一般舒適性環(huán)境產(chǎn)生更高的顯熱，基站空調(diào)養(yǎng)護(hù)，這極大改變了對(duì)制冷系統(tǒng)的要求。有兩種制冷類型：潛熱制冷和顯熱制冷。潛熱制冷是指空調(diào)系統(tǒng)消除濕氣的能力。這在一般舒適性制冷場(chǎng)合下很重要，例如辦公寫字樓、零售商店及人群密度較高的其他地方。潛熱制冷的重點(diǎn)是保持人們工作環(huán)境的溫濕度平衡。這些地方通常有直接通往外面的門和進(jìn)出口通道。上海森虞機(jī)電工程有限公司專業(yè)致力于精密空調(diào)生產(chǎn)。基站空調(diào)養(yǎng)護(hù)</p><div
