空調壓(ya)力傳感器壓(ya)力傳感器是一(yi)種能將(jiang)檢(jian)測到的(de)壓(ya)力信(xin)號轉換成電(dian)子信(xin)號，由電(dian)腦板芯(xin)片進(jin)行微(wei)處(chu)理，根據壓(ya)力檢(jian)測的(de)結(jie)果對空調機的(de)零部件(jian)進(jin)行精細的(de)控制(zhi)。
1、工作原理
為兩種壓力傳感器的外觀，如今絕大多數壓力傳感器都是電容式壓力傳感器，它由兩個靠近的平行膜片和一個堅固的小巧殼體構成。空(kong)(kong)(kong)(kong)調(diao)(diao)壓(ya)(ya)力(li)(li)(li)傳感(gan)器(qi)(qi)是自動空(kong)(kong)(kong)(kong)調(diao)(diao)控制(zhi)(zhi)(zhi)(zhi)系(xi)(xi)統的一個傳感(gan)器(qi)(qi)元件，其作用是防止(zhi)制(zhi)(zhi)(zhi)(zhi)冷(leng)系(xi)(xi)統在(zai)極限制(zhi)(zhi)(zhi)(zhi)冷(leng)劑(ji)管路壓(ya)(ya)力(li)(li)(li)下工作，并幫助控制(zhi)(zhi)(zhi)(zhi)發(fa)動機(ji)冷(leng)卻(que)風扇的轉(zhuan)速。 壓(ya)(ya)力(li)(li)(li)傳感(gan)器(qi)(qi)安裝在(zai)發(fa)動機(ji)艙內(nei)空(kong)(kong)(kong)(kong)調(diao)(diao)高壓(ya)(ya)管路上。該傳感(gan)器(qi)(qi)向發(fa)動機(ji)ECM或空(kong)(kong)(kong)(kong)調(diao)(diao)控制(zhi)(zhi)(zhi)(zhi)單元輸(shu)出壓(ya)(ya)力(li)(li)(li)信號，當檢測到空(kong)(kong)(kong)(kong)調(diao)(diao)制(zhi)(zhi)(zhi)(zhi)冷(leng)管路壓(ya)(ya)力(li)(li)(li)過低或過高時(shi)，控制(zhi)(zhi)(zhi)(zhi)系(xi)(xi)統停(ting)止(zhi)對空(kong)(kong)(kong)(kong)調(diao)(diao)壓(ya)(ya)縮(suo)機(ji)離合器(qi)(qi)供電，壓(ya)(ya)縮(suo)機(ji)停(ting)止(zhi)運(yun)轉(zhuan)，以免對空(kong)(kong)(kong)(kong)調(diao)(diao)系(xi)(xi)統造成損壞(huai)。當制(zhi)(zhi)(zhi)(zhi)冷(leng)劑(ji)壓(ya)(ya)力(li)(li)(li)達到一中等壓(ya)(ya)力(li)(li)(li)值時(shi)，散熱器(qi)(qi)風扇高速運(yun)轉(zhuan)，降低空(kong)(kong)(kong)(kong)調(diao)(diao)制(zhi)(zhi)(zhi)(zhi)冷(leng)劑(ji)壓(ya)(ya)力(li)(li)(li)。
