Ngokwezibalo, izinga lokusetshenziswa kwamandla lilonke lamabhizinisi okuqandisa liphezulu kakhulu, futhi izinga elimaphakathi lilonke liphakeme kakhulu kunezinga elimaphakathi lomkhakha ofanayo kwamanye amazwe. Ngokwezidingo ze-Institute of Refrigeration (IIR): eminyakeni engama-20 ezayo, "ukunciphisa ukusetshenziswa kwamandla kwemishini ngayinye yokuqandisa ngo-30%" "~50%", ngizobhekana nenselele enkulu, okwenza kubaluleke kakhulu ukuhlola izindlela zokonga amandla endaweni yokugcina ebandayo, ukunciphisa ukusetshenziswa kweyunithi yokupholisa kwemikhiqizo efrijini, ukuthuthukisa ukusetshenziswa kwesistimu, nokuqinisa ukuphathwa kwempahla yokugcina impahla. Indlela yokunciphisa ukusetshenziswa kwamandla ezindleleni zokugcina ebandayo, ukuqaphela ukonga amandla kwesistimu.
Yiziphi izici okufanele siziqaphele maqondana nokonga amandla ekuphathweni kokusebenza kwesitoreji esibandayo
1. Hlola futhi ulondoloze isakhiwo sendawo ebiyelwe njalo
Ukugcinwa kwesakhiwo sokugcina esibandayo kufanele futhi kudonsele ukunaka okukhulu endaweni yokugcina ebandayo. Ukutholwa kwe-infrared okwamanje kusetshenziswa ezimbonini eziningi. Isithombe esibizwa ngokuthi i-infrared thermal sithola amandla e-infrared (ukushisa) ngokungaxhumani bese siguqula sibe isignali kagesi. Idivayisi yokuthola ekhiqiza izithombe ezishisayo namanani okushisa esibukweni futhi ingabala amanani okushisa. Ingalinganisa ngokunembile ukushisa okutholiwe, ukuze ungagcini nje ngokubona izithombe ezishisayo, kodwa futhi uhlonze ngokunembile futhi uhlonze izindawo ezinephutha ezikhiqiza ukushisa. Ukuhlaziywa okuqinile.
2. Sebenzisa isikhathi sokugijima ebusuku ngendlela efanele
(1) Ukusetshenziswa kahle kukagesi we-peak kanye ne-valley ebusuku
Izindinganiso ezahlukene zokushaja ugesi ziyasetshenziswa ngokwezikhathi ezahlukene zokusetshenziswa kukagesi, futhi izifundazwe namadolobha ahlukahlukene nawo ashintshile ngokwezimo zangempela. Kunomehluko omkhulu phakathi kweziqongo nezigodi, futhi indawo yokugcina ugesi ebandayo idla amandla amaningi. Ingasetshenziswa ukugcina indawo yokugcina ugesi ebandayo ebusuku ukuze kugwenywe isikhathi esiphezulu sokusetshenziswa kukagesi emini.
(2) Ukusetshenziswa okunengqondo komehluko wokushisa phakathi kwemini nobusuku
Nginomehluko omkhulu wokushisa phakathi kwemini nobusuku. Ngokwezibalo, ukwehla ngakunye kwe-1°C ekushiseni kokujiya kunganciphisa ukusetshenziswa kwamandla kwe-compressor ngo-1.5% [22], futhi amandla okupholisa ngeyunithi ngayinye amandla omgodi azokhuphuka cishe ngo-2.6%. Izinga lokushisa elizungezile ebusuku liphansi, kanti izinga lokushisa lokujiya nalo lizokwehla. Ngokusho kwezincwadi, umehluko wokushisa phakathi kwemini nobusuku ezindaweni zesimo sezulu zaselwandle ungafinyelela ku-6-10°C, ezimweni zezulu zase-continental ungafinyelela ku-10-15°C, kanti ezifundeni eziseningizimu ungafinyelela ku-8-12°C, ngakho-ke ukwandisa isikhathi sokuqala ebusuku kuzuzisa ukonga amandla esitoreji esibandayo.
3. Khipha uwoyela ngesikhathi
Uwoyela onamathiselwe ebusweni be-heat exchanger uzobangela ukuthi izinga lokushisa lokuhwamuka kwe-evaporation lehle futhi izinga lokushisa lokuminyana kwe-condensation lenyuke, ngakho-ke uwoyela kufanele ukhishwe amanzi ngesikhathi, futhi indlela yokulawula ezenzakalelayo ingasetshenziswa, engeke nje inciphise umthwalo wezisebenzi kodwa futhi ilawule isikhathi nenani eliqondile lokukhipha amafutha.
4Vimbela igesi engangeni epayipini
Njengoba inkomba yomoya ye-adiabatic (n=1.41) inkulu kuneye-ammonia (n=1.28), lapho kukhona igesi engavundisi ohlelweni lokuqandisa, izinga lokushisa lokukhipha i-compressor yokuqandisa lizokhula ngenxa yokwanda kwengcindezi yokuvundisi kanye nomoya ocindezelwe. Izifundo zibonise ukuthi: lapho igesi engavundisi ixubene ohlelweni lokuqandisa futhi ingcindezi yayo engaphelele ifinyelela ku-0.2aMP, ukusetshenziswa kwamandla kohlelo kuzokwanda ngo-18%, futhi amandla okupholisa azokwehla ngo-8%.
5. Ukuncibilikisa iqhwa ngesikhathi esifanele
Isilinganiso sokudlulisa ukushisa sensimbi ngokuvamile siphindwe izikhathi ezingu-80 kunesithwathwa. Uma isithwathwa sakheka phezu komshini wokuhwamuka, sizokwandisa ukumelana nokushisa kwepayipi, sinciphise isilinganiso sokudlulisa ukushisa, futhi sinciphise amandla okupholisa. Kufanele sincibilikiswe ngesikhathi ukuze kugwenywe ukusetshenziswa kwamandla okungadingekile kohlelo.
Ukonga amandla ngokuqinisekile kuzoba yisihloko sentuthuko yomphakathi esikhathini esizayo. Izinkampani zokugcina izinto ezibandayo kufanele zithuthukise ukuqwashisa kwazo ngokuncintisana komphakathi futhi ziqhubeke nokuthuthuka ngaphansi kwezimo zomnotho wemakethe ukuze kuthuthukiswe intuthuko yemboni yethu yokugcina izinto ezibandayo.
