Amashishini amaninzi ngoku akhetha isikhongozeli esifrijiweyo endaweni yokwakha iindawo zokugcina izinto ezibandayo zemveli. Isikhongozeli esifrijiweyo sibonelela ngokuhambahamba, iindleko zotyalo-mali eziphantsi, kunye nokufakelwa ngokukhawuleza. Iinkampani ezifuna amandla okugcina izinto ezibandayo aguquguqukayo zihlala zixhomekeke kwesi sisombululo ukukhusela iimpahla ezinobushushu obuphantsi ngelixa zilawula iindleko zokusebenza.
Kutheni Amashishini Ekhetha Isikhongozeli Esifrijiweyo
Isitya esifrijiweyo sinika intuthuzelo esebenzayoisisombululo sokugcina izinto ezibandayokwiinkampani ezifuna ukuthunyelwa ngokukhawuleza kunye nolawulo lobushushu oluthembekileyo. Iindawo zokugcina izinto ezibandayo zemveli zifuna ukulungiswa komhlaba, iimvume zokwakha, kunye nemijikelo yokwakha emide. Ngokwahlukileyo koko, isitya esifrijiweyo sinokuqala ukusebenza kungekudala emva kokuhanjiswa nokufakwa.
Ukuguquguquka kuseyenye yezona nzuzo zinkulu. Amashishini anokubeka isikhongozeli esifrijini kumazibuko, kwiifama, kwiindawo zokusasaza, okanye kwizakhiwo zoshishino. Ukuba iimfuno zokusebenza ziyatshintsha, isikhongozeli sinokufuduselwa kwenye indawo ngokulula. Oku kuhambahamba kuvumela iinkampani ukuba zandise okanye zinciphise umthamo wokugcina izinto ezibandayo ngaphandle kotyalo-mali olukhulu lweziseko zophuhliso.
Ukusetyenziswa kakuhle kwamandla nako kudlala indima enkulu ekuthandweni kwezikhongozeli ezifrijiweyo. Iiyunithi zanamhlanje zisebenzisa iiphaneli zokukhusela ezisebenza kakuhle kunye neenkqubo ze-compressor eziphambili. Ezi teknoloji zigcina amaqondo obushushu azinzileyo ngelixa zinciphisa ukusetyenziswa kombane. Iinkqubo ezininzi zezikhongozeli ezifrijiweyo zixhasa ubushushu obuphakathi kwe-−30°C ukuya kwi-+10°C. Olu luhlu olubanzi luvumela amashishini ukuba agcine inyama efriziweyo, ukutya kwaselwandle, imifuno, iimveliso zobisi, kunye nezixhobo zonyango.
Enye inzuzo ibandakanya isantya sokufakela. Isikhongozeli esifrijiweyo sidla ngokufuna kuphela umphezulu womhlaba ozinzileyo kunye noqhagamshelo lombane. Iingcali zingagqiba ukuseta ngexesha elifutshane. Iinkampani ezihlangabezana nemfuno yexesha elithile zihlala zithenga okanye ziqeshe ezinye izikhongozeli ezifrijiweyo ngexesha lexesha elixakekileyo.
Ukuqina kwayo kuqinisa ixabiso lesi sicombululo. Uninzi lweeyunithi zeekhonteyina ezifrijiweyo zisebenzisa izakhiwo zentsimbi ezingamelani nokugqwala ezenzelwe iimeko zokuthunyelwa kwamanye amazwe. Ezi zakhiwo zinyamezela imvula, umoya, kunye nokuguquguquka kwamaqondo obushushu ngaphandle kwemfuneko enkulu yokugcinwa. Amashishini athenga ikhonteyina efrijiweyo ke ngoko afumana ubomi obude benkonzo kunye neendleko zokusebenza eziqikelelweyo.
Izinto ezibalulekileyo ekufuneka ziqwalaselwe
Iinkampani kufuneka zihlole izinto ezininzi zobugcisa ngaphambi kokuba zithenge isitya esifrijiweyo. Ukukhetha okufanelekileyo kuqinisekisa ukusebenza okuzinzileyo kwaye kukhusela impahla exabisekileyo.
Ukusebenza kobushushu yeyona nto iphambili. Iimveliso ezahlukeneyo zifuna iimeko ezahlukeneyo zokugcina. Ukutya kwaselwandle okuqandisiweyo kudla ngokufuna amaqondo obushushu amalunga ne-−18°C, ngelixa imveliso entsha ifuna amazinga aphezulu phakathi kwe-0°C kunye ne-5°C. Abathengi kufuneka baqinisekise ukuba iyunithi yokuqandisa yesikhongozeli esiqandisiweyo inokugcina amaqondo obushushu angaguquguqukiyo phantsi kweemeko zemozulu zasekuhlaleni.
Umgangatho wokufakwa kwe-insulation ukwachaphazela ukusebenza kunye neendleko zokusebenza. Ukufakwa kwe-polyurethane enoxinano oluphezulu kunciphisa ukudluliselwa kobushushu phakathi kwengaphakathi lesikhongozeli kunye nokusingqongileyo okungqongileyo. Ukufakwa kwe-insulation okuqinileyo kunceda izixhobo zefriji zigcine amaqondo obushushu ekujoliswe kuwo ngaphandle kokusebenzisa amandla amaninzi.
Ubungakanani kunye nomthamo kufuneka kuhambelane nomthamo wokugcina olindelekileyo. Ubungakanani obuqhelekileyo besikhongozeli esifrijiweyo buquka iiyunithi ezingama-20-foot kunye nama-40-foot. Amashishini amancinci anokukhetha iiyunithi ezincinci ngenxa yezidingo zokugcina ezilinganiselweyo. Abasasazi abakhulu badla ngokufaka izikhongozeli ezininzi ukwenza iinkqubo zokugcina ezibandayo ezimiselweyo.
Ukuhambelana kombane kubonisa enye into ebalulekileyo ekufuneka iqwalaselwe. Iiyunithi zeekhonteyina ezifakwe efrijini zihlala zisebenza kwiinkqubo zombane zoshishino. Abathengi kufuneka baqinisekise iimfuno ze-voltage, iindlela zombane ezixhasayo, kunye neziseko zombane zasekuhlaleni ngaphambi kokufakwa.
Inkxaso yokugcinwa kwezixhobo ikwachaphazela ukusebenza kwexesha elide. Ababoneleli abathembekileyo babonelela ngezixhobo ezingasetyenziswanga, isikhokelo sobugcisa, kunye nokulungiswa kwenkqubo yokukhenkceza. Iinkampani ezigcina izixhobo ngokufanelekileyo zinokwandisa ixesha lokusebenza kweeyunithi zazo zesikhongozeli esikhenkcezisiweyo.
