Ka'idar injin kwantar da iska ta evaporator
Na farko, nau'in evaporator
Evaporation shine tsarin jiki wanda ake canza ruwa zuwa gas. Tushen kwandishan abin hawa yana ƙunshe a cikin naúrar HVAC kuma yana haɓaka tururi na refrigeren ruwa ta hanyar busa.
(1) Babban tsarin nau'ikan evaporator: nau'in tubular, nau'in tubular, nau'in cascading, kwararar layi ɗaya
(2) Halayen nau'ikan evaporator iri-iri
The vane evaporator yana kunshe da aluminum ko jan karfe zagaye bututu wanda aka lullube da fis na aluminum. Fin ɗin aluminum suna cikin kusanci tare da bututun zagaye ta hanyar fadada bututu
Irin wannan tubular vane evaporator yana da tsari mai sauƙi da aiki mai dacewa, amma ingancin canja wurin zafi ba shi da kyau. Saboda dacewa da samarwa, ƙananan farashi, don haka ƙananan ƙananan ƙananan, ana amfani da tsofaffin samfurori.
Irin wannan evaporator ana welded ta lallausan lebur bututu da serpentine sanyaya aluminum tsiri. Tsarin ya fi rikitarwa fiye da na nau'in tubular. Haɗin aluminum mai gefe biyu da kayan lebur bututu ana buƙata.
Amfanin shi ne cewa an inganta ingantaccen canja wurin zafi, amma rashin lahani shi ne cewa kauri yana da girma kuma yawan ramukan ciki yana da girma, wanda ke da sauƙi don haifar da rashin daidaituwa na refrigerant a cikin ramukan ciki da kuma karuwar asarar da ba za a iya jurewa ba. .
Cascade evaporator shine tsarin da aka fi amfani dashi a yanzu. Ya ƙunshi faranti guda biyu na aluminium waɗanda ake wanke su zuwa sifofin hadaddun kuma an haɗa su tare don samar da tashar firiji. Tsakanin kowane tashoshi na haɗin gwiwa guda biyu akwai ƙwanƙwasa ƙwanƙwasa don zubar da zafi.
Abũbuwan amfãni ne high zafi canja wurin yadda ya dace, m tsarin, amma mafi wuya aiki, kunkuntar tashar, sauki toshe.
Parallel flow evaporator wani nau'in evaporator ne da aka saba amfani dashi yanzu. An haɓaka shi akan tsarin bututu da bel ɗin evaporator. Karamin mai musanya zafi ne wanda ya hada da bututu mai labule na jeri biyu da fin louver.
Abubuwan da ake amfani da su sune babban madaidaicin canja wurin zafi (idan aka kwatanta da ƙarfin musayar zafi na tubular ya karu da fiye da 30%), nauyi mai sauƙi, ƙaramin tsari, ƙarancin cajin refrigerant, da dai sauransu. Rashi shine gas-ruwa refrigerant biyu-lokaci tsakanin kowannensu. lebur tube yana da wuya a cimma daidaitattun rarrabawa, wanda ke rinjayar canjin zafi da rarraba filin zafi.
