11. A control system for a defrost heater in a refrigeration system, comprising:
-
a power supply connection; a controller configured to determine a demand side management state signal; and a power switching unit coupled between the power supply connection and the defrost heater, the power switching unit being configured to switch a power consumption state of the defrost heater in a defrost cycle from a standard power consumption mode to a reduced power consumption mode when the demand side management state signal is detected during the standard power consumption mode. - View Dependent Claims (12, 13, 14, 15, 16)
