摘要： A method of operating a refrigeration system that receives power from an electrical grid includes selectively operating at least one component of the refrigeration system in a first state. The method includes selectively detecting a fault event of the electrical grid in response to a concurrent (i) increase in amount of current drawn by the component and (ii) decrease in voltage of power received by the component. The method includes, in response to detecting the fault event, switching the component from the first state to a second state. The component consumes less power in the second state than in the first state. The method includes determining a first delay period. The method includes identifying a conclusion of the fault event. The method includes, in response to the conclusion of the fault event, waiting for the first delay period before switching the component back to the first state.

摘要： In a compressor shell built in an outdoor unit of an air conditioner, a compressor shell thermistor that detects a temperature of the shell is installed. Also, an outside air temperature thermistor that detects an outside air temperature is installed in an outdoor unit. The outside air temperature is compared with the compressor shell temperature, and if the shell temperature is higher than the outside air temperature, a compressor heating device is invalidated. If the shell temperature is lower than the outside air temperature, it is determined as a refrigerant collection condition, and the compressor heating device is operated. Also, if the shell temperature is higher than the outside air temperature by a certain temperature or more, the operation of the compressor heating device is stopped so that wasteful standby power is reduced, and energy of the apparatus is saved.
