Mavuto ofala a evaporator yosungiramo zinthu zozizira

Mu makina oziziritsira, kutentha kwa nthunzi ndi kuthamanga kwa nthunzi zimagwirizana.
Izi zikugwirizana ndi zinthu zingapo monga mphamvu ya compressor. Ngati chimodzi mwa zinthuzo chisintha, kutentha kwa evaporation ndi kuthamanga kwa evaporation kwa makina oziziritsira zidzasintha moyenerera. Mu malo osungira ozizira osunthika a BZL-3×4
, malo osungira nthunzi sanasinthe, koma mphamvu yake yosungiramo firiji yawirikiza kawiri, zomwe zimapangitsa kuti mphamvu yosungira nthunzi ya evaporator yosungiramo zinthu zozizira isagwirizane ndi mphamvu yoyamwa ya compressor (mphamvu yotulutsa nthunzi ya Vo).
Kakang'ono kwambiri kuposa mphamvu yoyamwa ya compressor (Vh), ndiko kuti, V0Ngati kutentha kwa tsitsi kuli kotsika kwambiri, chiŵerengero cha magwiridwe antchito a compressor chidzachepa, ndipo chiŵerengero cha zachuma chidzachepa.

1. Kapangidwe ka malo otulutsira nthunzi a evaporator ya zida zosungiramo zozizira pamodzi ndikosayenera:

Kapangidwe ka malo otulutsira nthunzi a evaporator mu malo osungiramo zinthu zoziziritsa pamodzi ndi kosiyana kwambiri ndi zofunikira zaukadaulo pa njira yeniyeni yoziziritsira. Malinga ndi zomwe zawonedwa nthawi yomweyo pa malo ena osungiramo zinthu zoziziritsa pamodzi, malo otulutsira nthunzi a evaporator ndi okhawo
Pali pafupifupi 75% zomwe ziyenera kukonzedwa. Tikudziwa kuti pokonza makina oyeretsera mpweya m'malo osungiramo zinthu zozizira pamodzi, kuwerengera kutentha kosiyanasiyana kuyenera kuchitika malinga ndi momwe kutentha kwake kumafunikira, ndipo mphamvu ya makina oyeretsera mpweya iyenera kudziwika.
Malo a tsitsi, kenako sinthani malinga ndi zofunikira za njira yoziziritsira. Ngati evaporator sinakonzedwe bwino malinga ndi zofunikira za kapangidwe kake ndipo malo okonzera evaporator achepetsedwa mosasamala, evaporator ya malo osungiramo ozizira ophatikizidwa idzawonongeka.
Kuchuluka kwa kuzizira pa gawo lililonse kumatsika kwambiri ndipo kuzizira kumawonjezeka, ndipo chiŵerengero cha mphamvu zogwiritsira ntchito bwino chimachepa kwambiri, zomwe zimapangitsa kuti kutentha kuchepe pang'onopang'ono mu malo osungira ozizira osunthika, ndipo kuchuluka kwa ntchito mufiriji kumakwera.
Chifukwa chake, popanga ndikusankha evaporator ya malo osungira ozizira osunthika, dera la evaporator liyenera kusankhidwa malinga ndi kusiyana kwa kutentha komwe kumakhudza kutentha.

2. Kapangidwe ka chipangizo choziziritsira cha zipangizo zosungiramo zinthu zozizira pamodzi n'kosamveka:

Magawo oziziritsira omwe amakonzedwa pa malo osungiramo zinthu zozizira opangidwa ndi opanga ena sawerengedwa malinga ndi kuchuluka konse kwa kuziziritsa komwe kumawerengedwa malinga ndi kapangidwe ka malo osungiramo zinthu zozizira komanso makulidwe a gawo lotetezera kutentha la malo osungiramo zinthu zozizira omwe akugwira ntchito.
Kugawa koyenera, koma njira yowonjezera chiwerengero cha mayunitsi oziziritsira kuti akwaniritse zofunikira pakuziziritsa mwachangu m'nyumba yosungiramo zinthu. Mwachitsanzo, sitolo yosungiramo zinthu zozizira ya BZL-3×4 ndi yayitali mamita 4, mulifupi mamita 3, ndipo
Mamita 2.7, kuchuluka konse kwa nyumba yosungiramo zinthu ndi 28.723 cubic metres, yokhala ndi ma seti awiri a ma unit oziziritsira a 2F6.3 mndandanda ndi ma seti awiri a ma evaporator odziyimira pawokha a chubu cha kuwala cha serpentine, gawo lililonse ndi evaporator yodziyimira pawokha imapanga
Dongosolo lonse la firiji yoziziritsira. Malinga ndi kuyerekezera ndi kusanthula kwa katundu wa makina osungiramo ozizira, zitha kudziwika kuti katundu wa makina osungiramo ozizira ndi pafupifupi 140 (W/m3), ndipo katundu weniweni ndi
4021.22(W) (3458.25kcal), malinga ndi zomwe zili pamwambapa, malo osungiramo zinthu zozizira omwe amayendetsedwa ndi mafoni amasankha malo osungiramo zinthu zozizira a 2F6.3 (mphamvu yoziziritsira yokhazikika ya 4000kcal/h) yomwe ingakwaniritsenso zofunikira za malo osungiramo zinthu zozizira omwe amayendetsedwa ndi mafoni.
Zofunikira pa njira yozizira (mpaka -15°C ~ -18°C), chifukwa chake, ndikofunikira kukhazikitsa gawo lina lowonjezera la firiji pa nyumba yosungiramo zinthu, ndipo zidzawonjezeranso ndalama zosamalira chipangizocho.
