Ngokwezibalo, inqanaba lokusetyenziswa kwamandla xa lilonke lamashishini efriji liphezulu kakhulu, kwaye inqanaba lomndilili lilonke liphezulu kakhulu kunomgangatho ophakathi weshishini elifanayo phesheya. Ngokweemfuno zeZiko lokuQinisekisa (IIR): kwiminyaka engama-20 ezayo, "ukunciphisa ukusetyenziswa kwamandla kwisixhobo ngasinye sefriji ngama-30%" "~ 50%" injongo, ndiya kujongana nomngeni omkhulu, okwenza kubaluleke kakhulu ukuphonononga iindlela zokugcina amandla kwindawo yokugcina ebandayo, ukunciphisa ukusetyenziswa kweyunithi yokupholisa kweemveliso ezifakwe efrijini, ukuphucula ukusetyenziswa kwenkqubo, kunye nokomeleza ulawulo lwendawo yokugcina impahla. Indlela yokunciphisa ukusetyenziswa kwamandla kwiindleko zokugcina ezibandayo, qaphela ukonga amandla enkqubo.
Zeziphi iinkalo ekufuneka sinikele ingqalelo kuzo ngokwemigaqo yokonga amandla kulawulo lomsebenzi wogcino olubandayo
1. Hlola rhoqo kwaye ugcine isakhiwo esivaliweyo
Ukugcinwa kwesakhiwo sokugcina okubandayo kufuneka kwakhona kutsale ingqalelo enkulu kwindawo yokugcina ebandayo. Ukufunyanwa kwe-infrared okwangoku kusetyenziswa kumashishini amaninzi. Into ebizwa ngokuba yi-infrared thermal imager ibona amandla e-infrared (ubushushu) ngokungadibanisi kwaye iguqulelwe kwisignali yombane. Isixhobo sokubona esenza imifanekiso eshushu kunye namaxabiso obushushu kumboniso kwaye sinokubala amaxabiso obushushu. Iyakwazi ukulinganisa ngokuchanekileyo ubushushu obufunyenweyo, ukwenzela ukuba awukwazi ukujonga kuphela imifanekiso ye-thermal, kodwa uchonge ngokuchanekileyo kwaye uchonge iindawo eziphosakeleyo ezivelisa ukushisa. Uhlalutyo olungqongqo.
2. Lisebenzise ngokufanelekileyo ixesha lokubaleka ebusuku
(1) Ukusetyenziswa ngokufanelekileyo kombane wencopho kunye nentlambo ebusuku
Imigangatho eyahlukeneyo yokutshaja umbane iphunyezwa ngokwamaxesha ahlukeneyo okusetyenziswa kombane, kwaye amaphondo ahlukeneyo kunye nezixeko nazo zilungelelanisiwe ngokweemeko zokwenyani. Kukho umahluko omkhulu phakathi kweencopho kunye neentlambo, kwaye ukugcinwa okubandayo kudla amandla amaninzi. Ingasetyenziselwa ukugcina ugcino olubandayo ebusuku ukuphepha ixesha eliphezulu lokusetyenziswa kombane emini.
(2) Ukusetyenziswa okufanelekileyo kokumahluko kobushushu phakathi kwemini nobusuku
Ndinomahluko omkhulu wobushushu phakathi kwemini nobusuku. Ngokwezibalo, yonke i-1 ° C yehla kwiqondo lobushushu le-condensation inokunciphisa ukusetyenziswa kwamandla e-compressor nge-1.5% [22], kwaye umthamo wokupholisa ngeyunithi nganye yamandla ombane uya kunyuka malunga ne-2.6%. Ubushushu be-ambient ebusuku buphantsi, kwaye ubushushu be-condensation buya kuhla. Ngokutsho kweencwadi, ukuhluka kweqondo lokushisa phakathi kwemini nobusuku kwiindawo zemozulu zolwandle kunokufikelela kwi-6-10 ° C, kwiindawo zezulu zelizwekazi zingafikelela kwi-10-15 ° C, kwaye kwimimandla esemazantsi inokufikelela kwi-8-12 ° C, ngoko ke ukwandisa ixesha lokuqalisa ebusuku kunenzuzo ekugcinweni kwamandla okugcinwa okubandayo.
3. Khupha ioli ngexesha
I-oyile encanyathiselwe kumphezulu we-heat exchanger iya kubangela ukuba ubushushu be-evaporation buhla kwaye ubushushu be-condensation bunyuke, ngoko ke i-oyile kufuneka ikhutshwe ngexesha, kwaye indlela yokulawula ngokuzenzekelayo inokwamkelwa, engakwazi ukunciphisa umthwalo wabasebenzi kuphela kodwa iphinde ilawule ixesha elichanekileyo lokukhupha i-oyile kunye nemali.
4. Thintela irhasi engacondensable ukuba ingangeni kumbhobho
Ekubeni i-adiabatic index of air (n = 1.41) inkulu kune-ammonia (n = 1.28), xa kukho i-gas engaguqukiyo kwi-refrigeration system, ukushisa kokukhutshwa kwe-compressor yefriji kuya kwanda ngenxa yokunyuka koxinzelelo kunye nomoya oxinyiweyo. Uphononongo lubonise ukuba: xa igesi engaguqukiyo ixutywe kwinkqubo yefriji kwaye uxinzelelo lwalo oluyinxenye lufikelela kwi-0.2aMP, ukusetyenziswa kwamandla kwenkqubo kuya kwanda nge-18%, kwaye amandla okupholisa aya kuncipha nge-8%.
5. Ukutshatyalaliswa ngexesha elifanelekileyo
I-coefficient yokudlulisa ukushisa kwentsimbi ngokuqhelekileyo malunga namaxesha angama-80 eqabaka. Ukuba iqabaka iyabumba kumphezulu we-evaporator, iya kwandisa ukuxhathisa kwe-thermal yombhobho, ukunciphisa i-coefficient yokudlulisa ubushushu, kunye nokunciphisa umthamo wokupholisa. Kufuneka ichithwe ngexesha ukuphepha ukusetyenziswa kwamandla okungeyomfuneko kwenkqubo.
Ukonga amandla ngokuqinisekileyo kuya kuba ngumxholo wophuhliso loluntu kwixesha elizayo. Iinkampani zokugcina izinto ezibandayo kufuneka zikhulise ulwazi lwazo ngokhuphiswano lwentlalo kwaye ziqhubeke ziphucula phantsi kweemeko zoqoqosho lwentengiso ukuze kuphuculwe uphuhliso lweshishini lethu lokugcina izinto ezibandayo.
