1. Semi-hermetic pisitoni kompresa firiji.
Mwa mitundu yosiyanasiyana ya ma compressor a firiji, ma piston compressor ndi akale kwambiri ndipo amagwiritsidwabe ntchito mobwerezabwereza. Mwachitsanzo, ma semi-hermetic piston refrigeration compressor amagwiritsidwa ntchito kwambiri pazida zamafiriji. Opanga wamba ndi: Emerson, Bitzer, ndi ma compressor ena.
Makhalidwe a semi-hermetic piston firiji kompresa: osiyanasiyana kuthamanga ndi mphamvu firiji, zinthu zochepa zofunika, okhwima luso, ndi yosavuta kompresa dongosolo, koma mantha kwambiri kugwedezeka madzi.
Pali zolakwika ziwiri zomwe zimachitika mu semi-hermetic piston refrigeration compressor: zolakwika zamakina ndi zolakwika zamagetsi. Zowonongeka zamakina ndizovala kapena kuwonongeka kwa ndodo yolumikizira, crankshaft, mbale ya valve ndi mbale ya valve; kuwonongeka kwamagetsi kumakhala kofala kwambiri mufupipafupi, kuzungulira kotseguka ndi kuwotcha kwa mafunde amoto.
2. Mpukutu firiji kompresa.
Compressor ya scroll imapangidwa makamaka ndi: disk drive (scroll rotor), stationary disk (scroll stator), bulaketi, mphete yolumikizirana, chipinda chakumbuyo chakumbuyo, ndi shaft eccentric. Iwo akhoza kugawidwa mu otsika kuthamanga chipinda psinjika ndi mkulu kuthamanga chipinda.
The low-pressure cavity compressor imasonyeza kuti chipolopolo chonsecho ndi chochepa kutentha, ndipo chipolopolo cha chipolopolo (kupatulapo doko lotulutsa mpweya ndi mpweya wotulutsa mpweya) chimakhala chochepa; compressor yapang'onopang'ono ikuwonetsa kuti chipolopolo chonse chimakhala kutentha kwambiri, ndipo chipolopolo cha chipolopolo (kupatula doko loyamwa ndi chipinda choyamwa) chimakhala chokwera kwambiri.
Mawonekedwe a kompresa: kugwira ntchito kosasunthika, kugwedezeka pang'ono, malo ogwirira ntchito opanda phokoso, zobvala zochepa, magwiridwe antchito okhazikika, phokoso lochepa, moyo wautali, mtengo wapamwamba wa EER, ndipo amagwiritsidwa ntchito mufiriji ndi makina owongolera mpweya.
3. Screw firiji kompresa.
The screw refrigeration compressor imapangidwa makamaka ndi casing, rotor, bearing, shaft seal, pistoni yokwanira, ndi chipangizo chosinthira mphamvu. The wononga firiji kompresa ali ndi zomangira ziwiri ndi helical dzino grooves meshing ndi mozungulira, zomwe zimapangitsa kusintha kwa voliyumu pakati pa mano, kuti amalize ndondomeko kuyamwa ndi kompresa, ndi kuzirala mphamvu akhoza kusintha steplessly pakati pa 10% ndi 100%. Screw refrigeration compressor tsopano amagwiritsidwa ntchito kwambiri mufiriji ndi zida za HVAC.
Makhalidwe a wononga firiji compressors: rotor, kunyamula mphamvu ndi kuvala kukana ndi mkulu; kuchuluka kwa mpweya sikumakhudzidwa ndi kuthamanga kwa mpweya; imakhala yogwira ntchito kwambiri m'malo osiyanasiyana ogwira ntchito; imatha kuzindikira kusintha kosasunthika kwa mphamvu, osati tcheru ndi madzi.
Wina anafunsa mu Refrigeration Encyclopedia Technology Group pamaso ngati wononga kompresa akuwopa mantha madzi, ndipo anthu ambiri anayankha kuti saopa mantha madzi. M'malo mwake, wononga kompresa nawonso amawopa kugwedezeka kwamadzimadzi, koma wononga kompresa sizovuta kwambiri pakubweza kwamadzi pang'ono, ndipo kuchuluka kwamadzi obwerera kumapangitsa kuti kompresa isagwire bwino ntchito, yomwe imafunikira chidwi.
