Zotsatira za defrost thermostat ndikuwongolera kutentha kwa heater. Kudzera mwa defrost thermostat ulamuliro firiji mufiriji mkati mwa defrost Kutentha waya, Kuti firiji mufiriji evaporator frosting sadzakhala n'kudziphatika, Kuonetsetsa kuti mufiriji mufiriji ntchito bwino. Pali bimetallic ndi mechanical defrost thermostats.
Kupyolera mu chubu chowongolera kutentha kuti muwone kutentha mkati mwa firiji kuwongolera kuyambika kwa kompresa ndikuyimitsa, Kuti muzitha kuwongolera kutentha kwa firiji mosiyanasiyana kuti firiji igwiritse ntchito bwino (Mafiriji onse ali ndi thermostat). Defrost timer: Kupyolera mu kompyuta board memory chip kapena giya yamakina nthawi yowongolera firiji mkati mwa waya wotenthetsera wotenthetsera ntchito, Kuti frost freezer evaporator frost isamamatire, Kusiya firiji kuti igwire ntchito bwino (mafiriji oziziritsidwa ndi mpweya okha ali ndi ntchito ya defrost).
Thermostat ikhoza kukhazikitsa kutentha kwa defrost; Komanso adati kutentha kwa firiji kukatsika kuposa momwe mumasungira, The defrost relay imatseka ndikuyamba kuzizira. Mwachitsanzo, mumayika kutentha kwa defrost kukhala -15 ° C, Pamene kutentha kwa firiji kuli pansi -15 ° C, Yambani kupukuta.
Kumene, ena a thermostat zachokera ku thermostat kapena kompresa anasonkhanitsa maola ntchito anayamba defrost, Ndiko kuti defrost mkombero T1, The defrost nthawi T1 akhoza kukhazikitsidwa ndi wosuta. Monga 6 hours, 10 hours.
Pamene firiji kuti defrost, The m'munsi mwa evaporator Kutentha chubu kutenthetsa, Yambani defrosting. Pambuyo pa ayezi pa evaporator kusungunuka, Idzayenda motsatira mapaipi amadzi otsatirawa, Kufikira pansi pa thireyi yamadzi, kutentha kwa evaporator kukafika ziro pafupifupi madigiri 8, Defrosting idayima. Sichidzatulutsa nthunzi wa madzi, Koma kusungunuka chifukwa cha nthawi yayitali, Kutentha mkati mwa bokosi kudzawonjezeka pang'ono, Koma ntchito yonse ya firiji ilibe mphamvu.
