摘要
FIELD: heating.;SUBSTANCE: invention relates to refrigerating machine with built-in heater (8) of defrost system, provided with measuring device (10, 12) for measuring voltage on feeding outlets (11) of defrost system heater (8) and for generation of modulated driving signal with mark-to-space ratio depending on measured voltage value. Interrupter (9) of current supplied to defrost system heater (8) is put into operation by driving signal. Mark-to-space ratio of feeding voltage changes depending on measured voltage in order to limit fluctuations of power of defrost system heater caused by voltage fluctuations.;EFFECT: efficiency of defrost system and increase of defrost system heater economy.;11 cl, 3 dwg
