Ngokwezibalo, inqanaba lokusetyenziswa kwamandla lilonke kwiinkampani zefriji liphezulu, kwaye inqanaba eliphakathi lilonke liphezulu kakhulu kunenqanaba eliphakathi leshishini elifanayo kwamanye amazwe. Ngokweemfuno ze-Institute of Refrigeration (IIR): kwiminyaka engama-20 ezayo, "ukunciphisa ukusetyenziswa kwamandla kwezixhobo zefriji nganye nge-30%" "~50%", ndiza kujongana nomceli mngeni omkhulu, okwenza kubaluleke kakhulu ukuhlola iindlela zokonga amandla kwindawo yokugcina ebandayo, ukunciphisa ukusetyenziswa kweeyunithi zokupholisa iimveliso zefriji, ukuphucula ukusetyenziswa kwenkqubo, kunye nokuqinisa ulawulo lwendawo yokugcina impahla. Indlela yokunciphisa ukusetyenziswa kwamandla kwindleko zokugcina ebandayo, ukuqonda ukonga amandla kwenkqubo.
Zeziphi iinkalo ekufuneka siziqwalasele ngokubhekiselele ekongeni amandla kulawulo lwemisebenzi yokugcina izinto ezibandayo
1. Hlola kwaye ulondoloze isakhiwo esibiyelweyo rhoqo
Ukugcinwa kwesakhiwo sokugcina izinto ezibandayo kufuneka kutsale ingqalelo enkulu kwindawo yokugcina izinto ezibandayo. Ukufunyanwa kwe-infrared okwangoku kusetyenziswa kumashishini amaninzi. I-infrared thermal imager ibona amandla e-infrared (ubushushu) ngokungadibani kwaye iyiguqule ibe yisignali yombane. Isixhobo sokufumanisa esivelisa imifanekiso yobushushu kunye namaxabiso obushushu kwisibonisi kwaye sinokubala amaxabiso obushushu. Ingalinganisa ngokuchanekileyo ubushushu obufunyenweyo, ukuze ungagcini nje ngokubona imifanekiso yobushushu, kodwa uchonge ngokuchanekileyo kwaye uchonge iindawo ezineempazamo ezivelisa ubushushu. Uhlalutyo oluqatha.
2. Sebenzisa ixesha lokubaleka ebusuku ngokufanelekileyo
(1) Ukusetyenziswa ngokufanelekileyo kombane okwincopho nowentlambo ebusuku
Imigangatho eyahlukeneyo yokutshaja umbane iyasebenza ngokwexesha elahlukileyo lokusetyenziswa kombane, kwaye amaphondo nezixeko ezahlukeneyo nazo zihlengahlengisiwe ngokweemeko zokwenyani. Kukho umahluko omkhulu phakathi kweencochoyi neentlambo, kwaye indawo yokugcina umbane idla amandla amaninzi. Ingasetyenziselwa ukugcina indawo yokugcina umbane ebusuku ukuze kuthintelwe ixesha eliphezulu lokusetyenziswa kombane emini.
(2) Ukusetyenziswa ngokufanelekileyo komahluko wobushushu phakathi kwemini nobusuku
Ndinomahluko omkhulu kubushushu phakathi kwemini nobusuku. Ngokwezibalo, ukwehla kwe-1°C kwiqondo lobushushu lokufuma kunokunciphisa ukusetyenziswa kwamandla kwecompressor nge-1.5% [22], kwaye amandla okupholisa ngeyunithi nganye yamandla eshaft aya kwanda malunga ne-2.6%. Ubushushu obujikeleze ubusuku buphantsi, kwaye ubushushu bokufufuma buya kwehla. Ngokweencwadi, umahluko kubushushu phakathi kwemini nobusuku kwiindawo zemozulu zaselwandle unokufikelela kwi-6-10°C, kwiimeko zemozulu zamazwekazi unokufikelela kwi-10-15°C, kwaye kwimimandla esezantsi unokufikelela kwi-8-12°C, ngoko ke ukwandisa ixesha lokuqalisa ebusuku kuluncedo ekugcinweni kwamandla kwindawo yokugcina ebandayo.
3. Khupha ioyile ngexesha elifanelekileyo
Ioyile enamathele kumphezulu we-heat exchanger iya kubangela ukuba ubushushu bokufuma bube buthathaka kwaye ubushushu bokufuma bunyuke, ngoko ke ioyile kufuneka ikhutshwe amanzi ngexesha, kwaye indlela yokulawula ngokuzenzekelayo inokusetyenziswa, engayi kunciphisa kuphela umthwalo wabasebenzi kodwa ikwalawula ixesha kunye nobungakanani bokukhupha ioyile.
4. Nqanda igesi engangeniyo kwipayipi ukuba ingene
Ekubeni i-adiabatic index yomoya (n=1.41) inkulu kuneye-ammonia (n=1.28), xa kukho igesi engavuthiyo kwinkqubo yokuphola, ubushushu bokukhupha i-compressor yokuphola buya kwanda ngenxa yokwanda koxinzelelo lokuphola kunye nomoya ocinezelweyo. Izifundo zibonise ukuba: xa igesi engavuthiyo ixutywe kwinkqubo yokuphola kwaye uxinzelelo lwayo oluncinci lufikelela kwi-0.2aMP, ukusetyenziswa kwamandla kwenkqubo kuya kwanda nge-18%, kwaye amandla okupholisa aya kuncipha nge-8%.
5. Ukunyibilikisa iqhwa ngexesha elifanelekileyo
I-coefficient yokudlulisa ubushushu yentsimbi ngokubanzi imalunga namaxesha angama-80 e-frost. Ukuba i-frost iyenzeka phezu komphezulu we-evaporator, iya kwandisa ukumelana nobushushu bombhobho, inciphise i-coefficient yokudlulisa ubushushu, kwaye inciphise amandla okupholisa. Ifanele inyibilikiswe ngexesha ukuze kuthintelwe ukusetyenziswa kwamandla okungeyomfuneko kwenkqubo.
Ukonga amandla ngokuqinisekileyo kuya kuba ngumxholo wophuhliso loluntu kwixesha elizayo. Iinkampani zokugcina izinto ezibandayo kufuneka ziphucule ulwazi lwazo ngokhuphiswano loluntu kwaye ziqhubeke nokuphucula phantsi kweemeko zoqoqosho lwemarike ukuze kuphuculwe uphuhliso lweshishini lethu lokugcina izinto ezibandayo.
