In another embodiment of the invention, the control unit, the first temperature sensor and According to the data received from the second temperature sensor, the refrigerant flow from the second valve. to the refrigerator compartment evaporator or to the freezer compartment evaporator provides orientation. The control unit consists of the refrigerator compartment and the freezer. controlling the temperature of the compartment, the temperature of the refrigerator compartment if it is greater than the critical temperature; to the cooler compartment evaporator of the refrigerant, if the freezer compartment temperature is greater than the critical temperature of the freezer compartment; It ensures that the refrigerant is transmitted to the freezer compartment evaporator.
Böylelikle; öncelikle isil yükü fazla olan, içinde yer alan gida maddeleri bozulma riski tasiyan, bölmenin etkin bir sekilde sogutulmasi saglanmaktadir. Thus; First of all, the foodstuffs, which have a high thermal load, are spoiled. It is ensured that the compartment, which carries the risk, is cooled effectively.
Bulusun bir baska uygulamasinda, kontrol ünitesi, sogutucu bölme sicakligi sogutucu bölme limit sicakligindan küçük, dondurucu bölme sicakligi dondurucu bölme limit sicakligindan küçük ise kompresörün durdurularak, sogutucu akiskan iletiminin sonlandirilmasini saglamaktadir. Sogutucu bölmenin ve dondurucu bölmenin yeterince sogutuldugu durumda kontrol ünitesi sogutma çevrimini durdurarak enerji sarfiyatini önlemektedir. In another embodiment of the invention, the control unit, the refrigerator compartment temperature The refrigerator compartment temperature is lower than the limit temperature, the freezer compartment temperature is below the freezer If it is less than the chamber limit temperature, the compressor will be stopped and the refrigerant causes the transmission to be terminated. Refrigerator and freezer when the chamber is sufficiently cooled, the control unit will run the cooling cycle. It prevents energy consumption by stopping it.
Bu bulus ile, bölmelerdeki sogutma ihtiyaci düsük oldugunda, sogutucu akiskanin kondenserin sadece bir kismindan geçirilerek ilgili bölmeye gönderildigi, bölmelerin sogutma ihtiyacinin daha hizli karsilandigi bir sogutucu gerçeklestirilmektedir.
