Indlela yokusombulula ingxaki yokungabuyeli kakuhle kweoyile ye-screw chiller?

Zimbini iindlela zokubuyisa ioyile kwisiguquli, enye kukubuya kwezahluli zesahlulo, enye ukubuya kweoyile yombhobho wokubuyisa umoya. Isahluli seoyile sifakwe kumbhobho wecompressor exhaust. Ngokubanzi, i-50-95% yeoyile inokwahlulwa. Iziphumo zokubuya kweoyile zilungile, isantya siyakhawuleza, kwaye isixa seoyile esingena kwinkqubo yombhobho sincitshisiwe kakhulu, ngaloo ndlela sandisa ukusebenza ngaphandle kokubuya kweoyile. ixesha.

Kuqhelekile ukuba inkqubo yokubanda efrijini enemibhobho emide kakhulu, iinkqubo zokwenza ulwandle ezinamanzi apheleleyo, kunye nezixhobo zokomisa umkhenkce ezinamaqondo obushushu asezantsi kakhulu ukubuyela ngaphezulu kwemizuzu elishumi okanye kwimizuzu emininzi emva kokuqala, okanye encinci ukubuya kweoyile. Uyilo Inkqubo embi iya kubangela ukuba icompressor iyeke ngenxa yoxinzelelo lweoyile. Ukufakwa kwesahluli seoyile esisebenza ngokukuko kwinkqubo yefriji kunokwandisa ixesha lokusebenza okungabuyisi kwecompressor, ukuze isiguquli sikwazi ukudlula ngokukhuselekileyo kwinqanaba lokungabikho kwembuyekezo yeoyile emva kokuqala. .

Ioyile yokuthambisa engazahlulwanga iya kungena kwinkqubo kwaye ihambisane nefriji kumbhobho ukwenza ukujikeleza kweoyile. Emva kokuba ioyile yokuthambisa ingene kwi-evaporator, inxenye yeoyile yokuthambisa yahlulwe kwisikhenkcisi ngenxa yeqondo lobushushu eliphantsi kunye nokunyibilika okuphantsi; kwelinye icala, ubushushu obuphantsi kunye ne-viscosity ephezulu, ioyile yokuthambisa eyahlulweyo kulula ukubambelela eludongeni lwangaphakathi lombhobho, kwaye kunzima ukuhamba. Okukhona isezantsi iqondo lobushushu lomphunga, kokukhona kunzima ukubuyisa ioyile. Oku kufuna ukuba uyilo kunye nolwakhiwo lombhobho womphunga kunye nombhobho wokubuyela kufuneka ulungele ukubuyela kweoyile. Isiqhelo esiqhelekileyo kukwamkela uyilo lwemibhobho oluhlayo kunye nokuqinisekisa isantya esikhulu sokuhamba komoya.

Kwiinkqubo zefriji ezinamaqondo obushushu asezantsi ngokukodwa, ukongeza ekusebenziseni ukwahlula-hlula kweoyile okuphezulu, izinyibilikisi ezizodwa zihlala zongezwa ukuthintela ioyile yokuthambisa ekuthinteleni ii-capillaries kunye neevalvu zokukhulisa, kunye nokunceda ukubuyisa ioyile. Kwangelo xesha, abanye abantu basebenzisa ioyile eyakhelwe-ngaphakathi yesixhobo sokungenisa umoya endaweni yeoyile yangaphandle. Phezulu, igcina iindleko, kodwa ngokweendleko zexesha elide zokusetyenziswa kwenkqubo, iya kunyusa kuphela iindleko zokusebenza. Ukusebenza kwenkqubo kuya kusiba mandundu.

Kwizicelo ezenziwayo, iingxaki zokubuyisa ioyile ezibangelwe kukuyilwa okungalunganga kwe-evaporator kunye nomgca wokubuya aziqhelekanga. Kwiinkqubo ze-R22 kunye ne-R404A, ukubuya kweoyile komphunga okhukhulileyo kunzima kakhulu, kwaye uyilo lombhobho wokubuyisela ioyile lwenkqubo kufuneka ulumke kakhulu. Kwinkqubo enjalo, ukusetyenziswa kweoyile ephezulu yokusebenza kunokunciphisa kakhulu isixa seoyile esingena kwinkqubo yombhobho, kwaye sandise ngokufanelekileyo ixesha elingabuyisi lombhobho wokubuyisa umoya emva kokuqalisa.

Xa isiguquli siphezulu kune-evaporator, ukugoba ukubuya kweoyile kumbhobho wokubuyela nkqo kuyafuneka. Igobongo lokubuyisa kufuneka lidibane kangangoko ukunciphisa ukugcinwa kweoyile. Isithuba phakathi kweendawo zokubuya kweoyile kufuneka kufanelekile. Xa inani lokugoba ukubuya kweoyile likhulu ngokulinganayo, ezinye ioyile zokuthambisa kufuneka zongezwe. Umgca wokubuyisa ioyile wenkqubo yomthwalo eyahlukileyo kufuneka ulumke. Xa umthwalo uncitshisiwe, isantya sokubuyela komoya siya kuncipha, isantya esisezantsi kakhulu asikulungelanga ukubuya kweoyile. Ukuqinisekisa ukubuya kweoyile phantsi komthwalo ophantsi, umbhobho wokutsala nkqo ungamkela imibhobho ethe nkqo kabini.

Ngaphaya koko, ukuqala kokucinezelwa rhoqo akulunganga ukubuyela kweoyile. Ukusukela ukuba isiguquli siyeke ukusebenza ixesha elifutshane ngokuqhubekayo, akukho xesha lokwenza isantya esiphezulu somoya ohamba ngombhobho wokubuyela, kwaye ioyile yokuthambisa inokuhlala kuphela kumbhobho. Ukuba ukubuyiswa kweoyile kungaphantsi kweoyile kaBen, icompressor iya kufutshane neoyile. Ngokufutshane ixesha lokusebenza, ipayipi inde kwaye inkqubo inzima, kokukhona ingxaki yokubuyela kweoyile ibonakala kakhulu. Ke ngoko, ngokubanzi, musa ukuqala isiguquli rhoqo.

Ngamafutshane, ukunqongophala kweoyile kuya kudala ukungabikho kweoyile. Unobangela wokungabikho kweoyile ayisiyo isixa kunye nesantya se-screw-type chiller, kodwa kukubuya kweoyile okungalunganga kwenkqubo. Ukufakwa kwesahluli seoyile esisebenza ngokufanelekileyo kunokukhawuleza ukubuyisela ioyile kunye nokwandisa ixesha lokusebenza kwecompressor ngaphandle kokubuya kweoyile. Uyilo lwe-evaporator kunye nombhobho wegesi obuyayo kufuneka uthathe ukubuyela kweoyile ukuthathelwa ingqalelo. Amanyathelo olondolozo njengokuthintela ukuqala rhoqo, ukunciphisa ixesha, ukuzalisa ngexesha elifanelekileyo ifriji, kunye nokutshintshwa kwangexesha kweenxalenye zokunxiba (ezinje ngeebheringi) ziyanceda ekubuyiseni ioyile
