Ohlelweni lokuqandisa, izinga lokushisa lokuhwamuka kanye nengcindezi yokuhwamuka kuyasebenza komunye nomunye.
Kuhlobene nezimo eziningana njengomthamo we-compressor. Uma esinye sezimo sishintsha, izinga lokushisa lokuhwamuka kanye nengcindezi yokuhwamuka kohlelo lokuqandisa kuzoshintsha ngokufanele. Esitoreni esibandayo esinyakazayo se-BZL-3×4
, indawo yokuhwamuka ayikashintshi, kodwa umthamo wayo wesiqandisi uphindwe kabili, okwenza umthamo wokuhwamuka we-evaporator yokugcina ebandayo engahambisani nekhono lokumunca le-compressor (umthamo wokuhwamuka i-Vo
Incane kakhulu kunomthamo wokumunca we-compressor (Vh), okungukuthi, i-V0
1. Ukucushwa kwendawo yokuhwamuka kwe-evaporator yemishini yokugcina ebandayo ehlanganisiwe akunangqondo:
Ukuhlelwa kwendawo yokuhwamuka kwe-evaporator endaweni yokugcina ebandayo ehlanganisiwe kuhluke kakhulu ezidingweni zobuchwepheshe zenqubo yangempela yokuqandisa. Ngokusho kokubonwa kwangaleso sikhathi kwezinye izindawo zokugcina ezibandayo ezihlanganisiwe, indawo yokuhwamuka kwe-evaporator iwukuphela
Kukhona cishe ama-75% okufanele ahlelwe. Siyazi ukuthi ukuze kulungiselelwe i-evaporator endaweni yokugcina ebandayo ehlanganisiwe, ukubalwa kwemithwalo yokushisa ehlukahlukene kufanele kwenziwe ngokwezidingo zokushisa kwayo, futhi amandla okuhwamuka kwe-evaporator kufanele anqunywe.
Indawo yezinwele, bese uyilungisa ngokwezidingo zenqubo yokuqandisa. Uma i-evaporator ingalungiswanga kahle ngokwezidingo zomklamo futhi indawo yokucushwa kwe-evaporator incishisiwe ngokungaboni, i-evaporator yesitoreji esihlanganisiwe esibandayo izolimala.
Isilinganiso sokupholisa ngeyunithi ngayinye sehla kakhulu futhi umthwalo wokupholisa uyanda, futhi isilinganiso sokusebenza kahle kwamandla sehla kakhulu, okuholela ekwehleni kancane kwezinga lokushisa endaweni yokugcina ebandayo eshukumayo, futhi isilinganiso sokusebenza sesiqandisi sivame ukukhuphuka.
Ngakho-ke, lapho kuklanywa futhi kukhethwa i-evaporator yesitoreji esibandayo esinyakaziswayo, indawo ye-evaporator kufanele ikhethwe ngokuya ngomehluko omuhle kakhulu wokushisa kokudlulisa ukushisa.
2. Ukucushwa kweyunithi yokuqandisa yemishini yokugcina ebandayo ehlanganisiwe akunangqondo:
Amayunithi okuqandisa ahlelwe endaweni yokugcina ebandayo ehlanganisiwe ekhiqizwa abanye abakhiqizi awabalwa ngokuya ngomthwalo wokupholisa ophelele obalwa ngokuya ngomklamo wendawo yokugcina kanye nobukhulu besendlalelo sokufaka umswakama sesakhiwo esisebenzayo sendawo yokugcina ebandayo.
Ukwabiwa okunengqondo, kodwa indlela yokwandisa inani lamayunithi okuqandisa ukuze kuhlangatshezwane nezidingo zokupholisa ngokushesha endaweni yokugcina impahla. Thatha isitoreji esibandayo esenziwe kusengaphambili se-BZL-3×4 njengesibonelo, isitoreji singamamitha angu-4 ubude, amamitha angu-3 ububanzi, futhi
Amamitha angu-2.7, umthamo ophelele wendawo yokugcina impahla ungamamitha-cubic angu-28.723, ahlonyiswe ngamasethi amabili amayunithi okuqandisa angu-2F6.3 ochungechunge kanye namasethi amabili ama-evaporator azimele e-serpentine light tube, iyunithi ngayinye kanye ne-evaporator ezimele yakha ifomu le-a
Uhlelo oluphelele lokuqandisa ukuze kusebenze ukupholisa. Ngokusho kokulinganisa nokuhlaziywa komthwalo womshini wendawo yokugcina ebandayo, kungaziwa ukuthi umthwalo womshini wendawo yokugcina ebandayo esebenzayo ungaba ngu-140 (W/m3), kanti umthwalo wangempela uphelele.
4021.22(W) (3458.25kcal), ngokusho kwedatha engenhla, indawo yokugcina ebandayo yeselula ikhetha iyunithi yokuqandisa engu-2F6.3 (umthamo wokupholisa ojwayelekile ongu-4000kcal/h) futhi ingahlangabezana nezidingo zesitoreji esibandayo esiphathwayo.
Izidingo zenqubo yokubanda (kufika ku--15°C ~ -18°C), ngakho-ke, akudingekile ukumisa enye iyunithi yokuqandisa endaweni yokugcina impahla, futhi kuzokwandisa nezindleko zokulungisa iyunithi.
