解開(kāi)之后成為普通的計(jì)算方程，就可以直接在CPU中進(jìn)行計(jì)算，可以自由換算焓值、含濕量、露點(diǎn)溫度等工程中需要用到的關(guān)鍵物理值了。

聽(tīng)說(shuō)我有做過(guò)暖通空調(diào)方面的項(xiàng)目，就跟我聯(lián)系探討這個(gè)計(jì)算方法商業(yè)應(yīng)用的可行性。 并問(wèn)我是否有興趣， 如果有興趣可以直接給我一個(gè)函數(shù)塊試試看。

巧了，我在幾年前的項(xiàng)目中確實(shí)遇到過(guò)這個(gè)問(wèn)題。 然而我對(duì)空氣熱能方面的專業(yè)不懂，遇到這個(gè)需求的時(shí)候，先是從網(wǎng)上查了個(gè)簡(jiǎn)易近似方程，做了個(gè)函數(shù)，做在項(xiàng)目里面交工了。

但后來(lái)設(shè)備廠客戶反應(yīng)，我做的函數(shù)，有一些個(gè)別工況下計(jì)算出來(lái)的數(shù)值不準(zhǔn)。 然而我因?yàn)椴欢?，所以也沒(méi)辦法審核求證。

然后一怒之下，直接把客戶使用校對(duì)的那個(gè)數(shù)值表格要來(lái)，花了幾天之間整理數(shù)據(jù)，給錄入到PLC中了。 然后使用雙線性插值方法，做了個(gè)查詢函數(shù)。
