在實際應用工況下，最好板式換熱器價格想要選擇一臺換熱器使它滿足理論情況下換熱器選型所具備的所有要求幾乎是不可能的。一般情況下，我們在幫換熱器選型時，在滿足生產工藝條件的前提下，僅考慮一個或幾個相對重要的因素就可以了。所謂重要影響因素具有不確定性，是相對而言的，通常是由設置換熱器的目的來確定的。換熱器應容易維護。這就要求換熱器容易清理，對于易腐蝕、強震動等破壞的原件應易于更換，換熱器應滿足工程實際場地的要求。選用換熱器時應根據場地的限制考慮換熱器的直徑、長度、重量和換熱管結構等。換熱器應盡可能的經濟。合肥板式換熱器價格選用(yong)時(shi)應綜合考慮換熱(re)器的制(zhi)造(zao)成本、安(an)裝費(fei)用(yong)、維護費(fei)用(yong)等，應使換熱(re)器盡可能(neng)的經(jing)濟。
