Kev ceev faj kev tiv thaiv thiab kev txhaum kuaj ntawm lub valval expansion valve

1. Ua ntej kev teeb tsa, xyuas seb qhov ntsuas kub yog lawm.
2. Lub tshav dav hlau nthuav dav yuav tsum tau nruab ze ze rau Evaporator, nrog lub valve lub cev mounted ntsug ntsug.
3. Lub sijhawm teeb tsa, xyuas kom meej tias cov kua hauv qhov kub thiab txias sensor tseem nyob hauv pob. Yog li ntawd, pob yuav tsum tau nruab qis dua lub cev valve.
4. Thaum ua tau, nruab qhov ntsuas kub ntawm kab rov tav rov qab ntawm cov pa hluav taws xob ntawm cov evaporator qhov hluav taws xob, feem tsawg tsawg kawg yog 1.5 metres ntawm lub compressor nkag tau.
5. Zam kom txhim kho qhov ntsuas kub ntawm cov kav dej rov qab uas cov kua tau tsim.
6. Yog tus Evaporator Eraplet yog nruab nrog roj - sensor yog feem ntau ntsia ntawm lub evaporator qhov hluav taws xob, ua ntej cua sov.
7. Qhov ntsuas kub yog ib txwm muab tso rau ntawm Evaporator Rov qab cua yeeb nkab, tightly zoo nkauj yuav tsum ntxuav kom huv.
8. Yog hais tias txoj kab uas hla muaj ntau dua 255-degree kaum rau hauv qab cov yeeb nkab kom tiv thaiv cov pa rov qab los rau hauv qab ntawm cov yeeb nkab los ntawm kev cuam tshuam cov pob kub.

1. Txheeb xyuas cov superheat ntawm lub evaporator qhov hluav taws xob siv tus pas ntsuas kub lossis los ntawm kev saib lub siab nqus siab.

2. Yog hais tias tus expansion valve superheat tau teeb tsa qis dhau los yog ib qho kev hloov tsheb loj heev, txo qhov chaw nres tsheb loj, txo cov raj hlav hlav ntau dhau, txo qhov chaw tso pa tawm, txo cov raj hlav valve, thiab txo cov raj tso tawm hauv lub valve, thiab txo cov raj tso tawm hauv valve, thiab txo cov raj tso tawm hauv lub valve, thiab txo cov raj ntsuas hluav taws xob, txo qis lub tub yees txias. Kev hloov kho tus pas nrig yuav tsum tsis txhob muab ntau zaus nyob rau ib lub sijhawm; Ib tig ntawm kev kho tus pas nrig hloov pauv cov superheat los ntawm kwv yees li 1-2 degrees.

3. Kev paub nyob rau hauv expansion valve hloov kho: kho tus hloov kho kom haum rau cov ntawv siv valve kom yog cov yeeb nkab xa cov yeeb nkab rov qab. Rau cov koog uas nyob hauv qab no 0 degree, yog tias koj hnov ​​cov nplaum, txias thaum koj kov nws, lub valve qhib yog qhov tsim nyog. Rau kev ua kom sov siab tshaj 0 degree, theem kev ua kom haum tau siv los txiav txim siab qhov kev nthuav dav hluav taws xob txias thiab txuag hluav taws xob. Qeeb txias cia khoom txias yog feem ntau vim muaj kev nthuav dav dav dav valve hloov kho. Raws li cov khoom siv kub thermodynamic ntawm cov tub yees, qis dua siab sib raug rau qis dua qhov kub thiab txias, thaum siab dua siab sib raug zoo dua. Kev hloov kho ntawm lub valve valve yog qhov tseem ceeb heev. Lub voj voog expleational valve qhib txo tub yees ntws tawm thiab lowers siab. Ib qho kev nthuav dav dav dav qhib kev nce ntxiv thiab ua kom muaj zog thiab siab dua.

Yog hais tias lub chaw nthuav dav valve hluav taws xob siab yog tsawg heev, qhov sib piv evaporation siab thiab ntsuas kub kuj tseem tsawg. Txawm li cas los xij, cov neeg khiav dej ntws tsawg thiab siab nkag mus rau Evaporator qeeb lub evaporator tus nqi, txo lub peev xwm cua txias rau ntawm cov ntim ntim thiab sijhawm, thiab txo qis txias txias ua hauj lwm txias. Hloov siab, yog hais tias lub chaw nthuav dav valve hluav taws xob siab dhau lawm, ua raws li txoj kev siab siab evaporate thiab kub kuj siab dhau. Qhov no nce ob qho tib si ntws thiab siab nkag mus rau evaporator. Cov kua dej ulitive ntau ua rau ntau dua cov roj av noo, lossis ua kom cov pa ntub dej (ua kua rauj Yog li ntawd, qhib℃ntawm expansion valve yuav tsum tau hloov kho raws li cov chaw tsim khoom kub tam sim no, uas yog, hloov kho ntawm lub siab sib xws nrog cov khoom siv kub.
