Common mavuto ozizira yosungirako evaporator

Mu firiji dongosolo, kutentha evaporating ndi evaporating kuthamanga ndi ntchito ya wina ndi mzake.
Zimakhudzana ndi zinthu zingapo monga mphamvu ya compressor. Ngati chimodzi mwa zinthu chikusintha, kutentha kwa evaporation ndi kuthamanga kwa evaporation kwa firiji kumasintha moyenerera. Mu BZL-3 × 4 kusungirako kuzizira kosuntha
, dera la evaporation silinasinthe, koma mphamvu yake ya firiji yawonjezeka kawiri, zomwe zimapangitsa kuti mpweya wa evaporator osunthika ukhale wosagwirizana ndi kuyamwa kwa compressor (the evaporation capacity Vo
Zochepa kwambiri kuposa mphamvu zoyamwa za kompresa (Vh), ndiye kuti, V0Ngati kutentha kwa tsitsi kumakhala kotsika kwambiri, index ya ntchito ya compressor idzachepa, ndipo index yachuma idzawonongeka.

1. Kusintha kwa dera la evaporator la zida zophatikizira zosungirako kuzizira ndizosamveka:

Kukonzekera kwa dera la evaporator mu malo ozizira osakanikirana ndi osiyana kwambiri ndi zofunikira zaumisiri wa firiji. Malinga ndi zowonera-po-pomwepo pazosungirako zozizira zina, malo owukira a evaporator ndi okhawo.
Pali pafupifupi 75% yomwe iyenera kukhazikitsidwa. Tikudziwa kuti kasinthidwe ka evaporator mu malo ozizira ophatikizana, mawerengedwe a katundu wotentha wosiyanasiyana amayenera kuchitidwa molingana ndi kapangidwe kake ka kutentha, ndipo mphamvu ya evaporator iyenera kutsimikiziridwa.
Malo atsitsi, ndiyeno konzekerani malinga ndi zofunikira za ndondomeko ya firiji. Ngati evaporator sichidasanjidwe bwino molingana ndi kapangidwe kake ndipo malo osinthika a evaporator amachepetsedwa mwakhungu, evaporator yosungirako kuzizira kophatikizana idzawonongeka.
Kuzizira kozizira pagawo la unit kumatsika kwambiri ndipo kuzizira kumawonjezeka, ndipo chiŵerengero cha mphamvu zamagetsi chimachepa kwambiri, zomwe zimapangitsa kuti kutentha kwapang'onopang'ono kusungidwe kosungirako kuzizira, ndipo coefficient yogwira ntchito ya firiji imakonda kukwera.
Chifukwa chake, popanga ndikusankha evaporator ya malo ozizira osunthika, gawo la evaporator liyenera kusankhidwa molingana ndi kusiyana kwa kutentha kwa kutentha.

2. Kukonzekera kwa chipinda cha firiji cha zipangizo zosungirako zozizira zophatikizana ndizosamveka:

The refrigerating mayunitsi kukhazikitsidwa pa ophatikizana ozizira yosungirako opangidwa ndi opanga ena si masamu malinga ndi katundu kuzirala okwana masamu malinga ndi kamangidwe ka yosungirako ndi makulidwe a kutchinjiriza wosanjikiza wa yogwira ozizira yosungirako mpanda dongosolo.
Kugawikana wololera, koma njira kuonjezera chiwerengero cha mayunitsi firiji kukwaniritsa zofunika kuzirala mofulumira mu nyumba yosungiramo katundu. Tengani BZL-3 × 4 kusungirako kozizira koyambirira monga chitsanzo, kusungirako ndi 4 mita kutalika, 3 mita m'lifupi, ndi
2.7 metres, voliyumu ya nyumba yosungiramo katunduyo ndi 28.723 cubic metres, yokhala ndi ma seti 2 a 2F6.3 mayunitsi afiriji ndi seti ziwiri za evaporators odziyimira pawokha a serpentine light chubu, unit iliyonse ndi evaporator yodziyimira payokha.
Malizitsani firiji kuti muzizizira. Malinga ndi kuyerekezera ndi kusanthula kwa katundu wa makina osungira ozizira, zitha kudziwika kuti katundu wa makina osungira ozizira amakhala pafupifupi 140 (W / m3), ndipo katundu weniweni ndi.
4021.22 (W) (3458.25kcal), malinga ndi zomwe tafotokozazi, malo ozizira ozizira amasankha 2F6.3 mndandanda wa firiji (muyezo wozizira wa 4000kcal / h) ungathenso kukwaniritsa zofunikira za malo ozizira ozizira.
Zofunikira pakuzizira (mpaka -15 ° C ~ -18 ° C), chifukwa chake, ndizofunikanso kukonza firiji imodzi panyumba yosungiramo katundu, komanso kuonjezera mtengo wokonza gawolo.
