Indlela yokubala ukuba zingaphi ii-cooler zomoya ezifunekayo kwindawo yokusebenzela

Indlela yokubala ukuba zingaphiishishini umoya opholileyoziyafuneka kwiworkshop. Ngokuphuhliswa kogcino lwamandla kunye nobuchwephesha bokupholisa umoya ngokusingqongileyo, ziya zisanda iifektri neendibano zocweyo ezizikhethayo njengesixhobo sokuphefumla nokupholisa abasebenzi bazo. Uninzi lwabantu luthi zingaphi imveliso yomoya epholileyo efunekayo, vele ubuze umthengisi oqeqeshiweyo okanye igcisa lokupholisa umoya kwishishini. Enyanisweni, ngaphambi koku, unokufunda nokubala ukuba bangaphiishishini umoya opholileyoudinga kwindawo yakho.

Okokuqala, sinokubala ngokwethiyori. Indlela yokubala kukuqala ukubala umthwalo wokupholisa, umthwalo omanzi kunye nomthamo wonikezelo komoya wendawo esetyenziswayo ngokwefomula yokubala yomthwalo opholileyo wesiqhelo, kwaye emva koko ubale umthamo wokupholisa uwonke onokunikezelwa ngumatshini wokupholisa umoya, ukuze ukhethe. ukonga umbane kunye nokukhuselwa kwendalo. Kwinani kunye nemodeli yesipholile somoya, umthamo wokupholisa uwonke weishishini umoya opholileyokufuneka ibe mkhulu kunomthamo wokupholisa ofunwa yindawo yokusetyenziswa, kwaye umthamo oseleyo unokuqwalaselwa ngokubanzi nge-10%.

Ubalo lwethiyori yomthamo opheleleyo wokupholisa weishishini umoya opholileyo:

Umthamo wokupholisa uwonke S=LρCp{e•(tg-ts)+tn-tg}/3600

kwi:

L——Elona qondo lonikezelo lomoya lokonga umbane kunye nesipholileyo somoya esivumelana nokusingqongileyo (m3/h)

Ρ——Ubuninzi bomoya kwindawo yokuphuma (kg/m3)

Cp——Ubushushu obuthile bomoya (kJ/kg•K)

E——Ukusebenza kakuhle kokupholisa umoya kwishishini, ngokubanzi ngama-85%

(Tg-ts)——Umahluko wobushushu bebhalbhu eyomileyo nemanzi (℃)

(Tn-tg)——Umahluko wobushushu phakathi kwangaphakathi nangaphandle (℃)

Seta △t1=(tg-ts), △t2=(tn-tg), apho △t1 lixabiso elivumayo, kwaye △t2 inexabiso elincomekayo nelingalunganga.

Umthamo wokupholisa uwonke S=LρCp(e•△t1+△t2), apho ρ, Cp, e zizigxina. Kunokubonwa ukuba umthamo wokupholisa uwonke weshishini lomoya opholileyo kunye neyona nto iphumayo yomoya opholileyo, umahluko phakathi kobushushu bebhalbhu eyomileyo nemanzi, Umahluko wobushushu phakathi kwangaphakathi nangaphandle unxulumene. Njengoko u-△t1 kunye no-△t2 zingengomlinganiselo ongaqinisekanga, ziyatshintsha ngotshintsho lwemo yendalo esingqongileyo yangaphandle, ngoko ke ifomula yesakhono sokupholisa sisonke sisetyenziswa kuphela kuhlalutyo lobulunga, kwaye ayifane isetyenziswe ekubaleni ubungakanani.

Okwesibini, sisebenzisa amava ethu ukubala inani lezixhobo ezisekelwe kwiimpawu ze-XIKOOishishini umoya opholileyo. Oko kukuthi, inani lotshintsho lomoya lisetyenziswa njengeparameter ukumisela inani leshishini lokupholisa umoya elifunekayo kwindawo ethile. Le yindlela yoyilo eqhele ukusetyenziswa kwishishini lokupholisa umoya.
