如此循環(huán)往復(fù),不斷地將熱源的熱能傳遞給冷凝水。根據(jù)熱力學(xué)定律,有:Qg=Qd+A,根據(jù)熱力學(xué)第二定律,壓縮機(jī)所消耗的電功A起到補(bǔ)償作用,使得制冷劑能夠不斷地從低溫環(huán)境吸熱(Q,并向高溫環(huán)境放熱(Qg),周而復(fù)始地進(jìn)行循環(huán)。壓縮機(jī)的能耗是一個(gè)重要的技術(shù)經(jīng)濟(jì)指標(biāo),一般用性能系數(shù)(coefficientofperbance,簡(jiǎn)稱COP)來(lái)衡量裝置的能量效率,其定義為:COP=Qg/A=(Qd+A)/A=1+Qd/A顯然,熱泵COP永遠(yuǎn)大于1。

運(yùn)轉(zhuǎn)環(huán)境的檢查。
⑴PLC運(yùn)轉(zhuǎn)環(huán)境溫度在0~60℃。溫度過(guò)高將使得PLC內(nèi)部元件功能惡化和毛病添加,尤其是CPU會(huì)因“電子搬遷”表象的加快而下降PLC的壽數(shù)。溫度偏低,模仿回路的安全系數(shù)也會(huì)變小,超低溫時(shí)能夠致使操控體系動(dòng)作不正常。處置的方法是在操控柜裝置適宜的軸流電扇或許加裝空調(diào),并留意常常檢查。
⑵環(huán)境相對(duì)濕度在5%~95%之間。在濕度較大的環(huán)境中,水分簡(jiǎn)單通過(guò)模塊上的IC的金屬表面的缺點(diǎn)侵入內(nèi)部,致使內(nèi)部元件功能的惡化,使內(nèi)部絕緣功能下降,會(huì)因高壓或浪涌電壓而致使短路;在極端枯燥的環(huán)境下,MOS集成電路會(huì)因靜電而致使擊穿。
⑶定時(shí)吹掃內(nèi)部塵埃,以確保風(fēng)道的疏通和元件的絕緣。
⑷檢查PLC的裝置狀態(tài)。各PLC單元固定是不是結(jié)實(shí),各種I/O模塊端子是不是松動(dòng),PLC通訊電纜的子母連接器是不是刺進(jìn)并旋緊,外部連接線有無(wú)損害。
⑸檢查PLC的程序存儲(chǔ)器的電池是不是需求替換。
