Mutu wogawa ngati kugawa sikuli kofanana, zimapangitsa kuti firiji yapansi panthaka ikhale yambiri, kotero kuti chisanu cha evaporator chimapangitsa kuti mpweya usapitirire, zomwe zimakhudza kuchepa kwa mphamvu ya firiji ya dongosolo, komanso zingayambitse kuyamwa ndi madzi.
1, poganizira kuchuluka kwa kayendedwe ka shunt.
(1) Ngati kuchuluka kwa madzi osinthira kuli pamwamba.
Coil outlet superheat ndi yaying'ono kwambiri, ndipo ngakhale ndi madzi osapsa, malo osamutsira kutentha ndi ochepera 1. Nthawi yomweyo, evaporator outlet manifold chifukwa cha kusakaniza kapena kusungunuka kwa refrigerant, superheat ndi yotsika kuposa mtengo wa | theoretical, superheat imachepa, chizindikiro chopangidwa ndi chipangizo cha throttle chimakhala ndi madzi ambiri, chipangizo cha throttle chimadzisintha kuti chichepetse kuchuluka kwa madzi;.
(2) Ngati kuchuluka kwa madzi osinthidwa kuli kochepa.
Kuchuluka kwa madzi m'thupi kumachepa, zotsatira za kulekanitsidwa kwa madzi zimakhala zoyipa kwambiri, zomwe zimapangitsa kuti pakhale kuzungulira koopsa; pamapeto pake zimapangitsa kuti malo ogwira ntchito a evaporator achepe kwambiri, mphamvu yozizira itsike, komanso kuti makina onse oziziritsira ayambe kuchepa.
2, Kuchokera ku machitidwe ogwirira ntchito a dongosolo lozizira.
(1) Pamene chipangizocho chikutenthetsa
Kugawanika kwa madzi osafanana kungayambitse kusungunuka kosakwanira kwa refrigerant mu dera lomwe madzi amagawika kwambiri, zomwe zingayambitse kuzizira mwachangu mu dera lino. Ngati kuzizira kuli kwakukulu kwambiri, kungayambitse kuzizira kusakhala koyera, kenako kuzungulira koipa, compressor idzabwerera ku madzi, ndipo kuthamanga kochepa kudzayima.
(2) Pamene chipangizocho chikuzizira
Ngati kusungunuka kwa madzi mufiriji sikukwanira mu dera lomwe madzi ambiri amalekanitsidwa, kutentha kwa coil kumakhala kochepa ndipo mphamvu yochotsera chinyezi imakhala yamphamvu, ndipo ngati ili yoopsa, coil yamkati idzazizira ndipo compressor idzabweza madzi.
