Mfundo ya evaporator yama air conditioning pamagalimoto
Choyamba, mtundu wa evaporator
Evaporation ndi njira yomwe madzi amasinthidwa kukhala gasi. Evaporator yamagetsi yamagalimoto ili mkati mwa gawo la HVAC ndipo imathandizira kutenthetsa kwa refrigerant yamadzimadzi kudzera mu chowuzira.
(1) Main dongosolo mitundu ya evaporator: tubular mtundu, tubular mtundu, cascading mtundu, kufanana otaya
(2) Makhalidwe amitundu yosiyanasiyana ya evaporator
Evaporator yokhala ndi aluminiyamu kapena chubu yozungulira yamkuwa yokhala ndi zipsepse za aluminiyamu. Zipsepse za aluminiyamu zimalumikizana kwambiri ndi chubu chozungulira ndi njira yokulitsa chubu
Mtundu uwu wa tubular vane evaporator umakhala ndi mawonekedwe osavuta komanso osavuta kukonza, koma kusamutsa kwa kutentha kumakhala kocheperako. Chifukwa cha kuphweka kwa kupanga, mtengo wotsika, kotero otsika kwambiri, zitsanzo zakale zimagwiritsidwabe ntchito.
Evaporator yamtunduwu imawotchedwa ndi porous flat chubu ndi serpentine yozizira aluminium strip. Njirayi ndi yovuta kwambiri kuposa ya mtundu wa tubular. Aluminiyamu yophatikizika yokhala ndi mbali ziwiri ndi zida zaporous flat chubu zimafunikira.
Ubwino wake ndikuti kutentha kwapang'onopang'ono kumayenda bwino, koma choyipa ndichakuti makulidwe ake ndi akulu ndipo kuchuluka kwa mabowo amkati ndi akulu, omwe ndi osavuta kutsogolera kumayendedwe osagwirizana a refrigerant m'mabowo amkati ndikuwonjezera kutayika kosasinthika. .
Cascade evaporator ndiye mawonekedwe omwe amagwiritsidwa ntchito kwambiri pakadali pano. Amapangidwa ndi mbale ziwiri za aluminiyamu zomwe zimatsukidwa m'mawonekedwe ovuta ndikuwotcherera pamodzi kupanga njira yopangira firiji. Pakati pa njira ziwiri zophatikizira pali zipsepse za wavy zochotsera kutentha.
Ubwino ndi mkulu kutentha kutengerapo dzuwa, kapangidwe yaying'ono, koma processing yovuta kwambiri, yopapatiza njira, zosavuta kutsekereza.
Parallel flow evaporator ndi mtundu wa evaporator womwe umagwiritsidwa ntchito kwambiri masiku ano. Amapangidwa pamaziko a chubu ndi lamba evaporator dongosolo. Ndi cholumikizira kutentha chophatikizika chopangidwa ndi mizere iwiri ya porous lathyathyathya chubu ndi zipsepse za louver.
Ubwino ndi mkulu kutentha kutengerapo coefficient (poyerekeza ndi tubular kutentha exchanger mphamvu chinawonjezeka ndi oposa 30%), kuwala kulemera, yaying'ono dongosolo, zochepa refrigerant nawuza kuchuluka, etc. The akusowa kuti mpweya-zamadzimadzi magawo awiri refrigerant pakati pa aliyense. lathyathyathya chubu n'zovuta kukwaniritsa kugawa yunifolomu, zomwe zimakhudza kutentha kutengerapo ndi kutentha kugawa kumunda.
