Kuthamanga kwa nthunzi, kutentha, ndi kuthamanga kwa kuzizira ndi kutentha kwa makina oziziritsira ndi zinthu zofunika kwambiri. Ndi maziko ofunikira pakugwira ntchito ndi kusintha. Malinga ndi momwe zinthu zilili komanso kusintha kwa makina, magawo ogwirira ntchito amasinthidwa nthawi zonse ndikuwongoleredwa kuti agwire ntchito motsatira magawo otsika mtengo komanso oyenera, zomwe zingatsimikizire chitetezo cha makina, zida ndi zinthu zosungidwa, kupereka mphamvu zonse pakugwiritsa ntchito bwino zida, ndikusunga ndalama. Madzi, magetsi, mafuta, ndi zina zotero.
Chifukwa chakeofkutentha kwa evaporationeotsika kwambiri
1. Chotenthetsera madzi (choziziritsira) ndi chaching'ono kwambiri
Pali vuto pa kapangidwe kake, kapena mtundu weniweni wa malo osungiramo zinthu ndi wosiyana ndi mtundu wa malo osungiramo zinthu omwe adakonzedwa, ndipo kutentha kumawonjezeka.
Yankho:Malo otulutsira nthunzi a evaporator ayenera kuwonjezeredwa kapena evaporator iyenera kusinthidwa.
2. Mphamvu yoziziritsira compressor ndi yayikulu kwambiri
Pambuyo poti katundu wosungidwa m'nyumba yosungiramo zinthu wachepetsedwa, mphamvu ya compressor sinachedwe pakapita nthawi. Compressor yosungiramo zinthu zozizira imafanana ndi katundu wochuluka wa makina oziziritsira, ndipo katundu wochuluka wa malo osungiramo zinthu zozizira a zipatso ndi ndiwo zamasamba umachitika panthawi yosungiramo katundu. Nthawi zambiri, katundu wa compressor ndi wochepera 50%. Kutentha kosungirako kukatsika kufika pa kutentha koyenera kosungirako, katundu wa makinawo umachepa kwambiri. Ngati makina akuluakulu akadali kuyatsidwa, trolley yayikulu yokokedwa ndi akavalo idzapangidwa, kusiyana kwa kutentha kudzawonjezeka, ndipo mphamvu zomwe zimagwiritsidwa ntchito zidzawonjezeka.
Yankho:kuchepetsa chiwerengero cha ma compressor omwe amayatsidwa kapena kuchepetsa chiwerengero cha masilinda ogwira ntchito ndi chipangizo chowongolera mphamvu malinga ndi kusintha kwa katundu wosungiramo katundu.
3. Chotsukira mpweya sichisungunuka pakapita nthawi
Yankho:Chipale chofewa pa evaporator coil chimachepetsa kutentha komwe kumafunikira, kumawonjezera kukana kutentha, kumachepetsa kutentha komwe kumafunikira, komanso kumachepetsa kutuluka kwa mpweya mu refrigerant. Mphamvu ya compressor ikapitirirabe kusintha, kuthamanga kwa mpweya mu dongosolo kumachepa. Kutentha komwe kumafunikira kutuluka kwa mpweya kumachepa, kotero sungunukani pakapita nthawi.
4. Mu evaporator muli mafuta odzola
Mafuta opaka mu evaporator amapanga filimu yamafuta pakhoma la chubu cha evaporator, zomwe zimachepetsanso kutentha, kuonjezera kukana kutentha, kuchepetsa kutentha, kuchepetsa kutuluka kwa evaporator, ndikuchepetsa kuthamanga kwa evaporation ya system. , kutentha kofanana kwa evaporation kumachepa, kotero mafuta ayenera kutsanulidwa kupita ku system pakapita nthawi, ndipo mafuta opaka mu evaporator ayenera kutulutsidwa ndi frosting yotentha ya ammonia.
5. Valavu yokulitsa imatsegulidwa yaying'ono kwambiri
Kutseguka kwa valavu yokulitsa ndi kochepa kwambiri, ndipo madzi omwe amapezeka mu dongosololi ndi ochepa. Popeza mphamvu ya compressor siisintha, kuthamanga kwa nthunzi kumachepa, zomwe zimapangitsa kuti kutentha kwa nthunzi kuchepe.
Yankho:Mlingo wotsegulira wa valavu yowonjezera uyenera kuwonjezeka.
Zifukwa za kupanikizika kwakukulu kwa mpweya
Pamene mphamvu ya condensation ikwera, ntchito ya compression imawonjezeka, mphamvu yozizira imachepa, mphamvu yozizira imachepa, ndipo mphamvu yogwiritsira ntchito mphamvu imawonjezeka. Akuti ngati zinthu zina sizikusintha, mphamvu yogwiritsira ntchito mphamvu imawonjezeka ndi pafupifupi 3% pa 1°C iliyonse yomwe imawonjezeka kutentha kwa condensation kofanana ndi mphamvu ya condensation. Kawirikawiri amaganiziridwa kuti kutentha kwa condensation komwe kumakhala kotsika mtengo komanso koyenera kumakhala kokwera ndi 3 mpaka 5 °C kuposa kutentha kwa madzi ozizira.
Zifukwa ndi njira zothetsera kuwonjezeka kwa kuthamanga kwa condenser:
1. Kondensala ndi yaying'ono kwambiri, sinthani kapena onjezerani kondensala.
2. Chiwerengero cha ma condenser omwe amagwiritsidwa ntchito ndi chochepa, ndipo chiwerengero cha ntchito chikuwonjezeka.
3. Ngati madzi ozizira sakuyenda mokwanira, onjezerani kuchuluka kwa mapampu amadzi ndikuwonjezera madzi.
4. Kugawa madzi a kondensala sikofanana.
5. Mulingo wa paipi ya condenser umapangitsa kuti kutentha kukhale kolimba, ndipo ubwino wa madzi uyenera kukonzedwa ndi kukulitsidwa pakapita nthawi.
6. Muli mpweya mu condenser. Mpweya mu condenser umawonjezera kupanikizika pang'ono mu dongosolo ndi kupanikizika konse. Mpweya umapanganso mpweya pamwamba pa condenser, zomwe zimapangitsa kuti kutentha kukhale kolimba, zomwe zimachepetsa mphamvu yotumizira kutentha, zomwe zimapangitsa kuti kupanikizika ndi kuzizira kwa mpweya zikwere. Kutentha kukakwera, mpweya uyenera kutulutsidwa pakapita nthawi.
