    摘要: A current detector and a voltage detector respectively detect a current value and a voltage value outputted from an engine generator. An operating block determines a weight constant on the basis of the current value and the voltage value, weights the operating time of an engine by using the weight constant, and integrates the weighted operating time to calculate an integral time. A judging block compares the integral time and a reference time, and gives a notification to an indicator when it judges that the integral time exceeds the reference time. Receiving the notification, the indicator makes an external indication. The current detector and the voltage detector can be made of electric circuitry, so that the life of the engine can be predicted at low costs and with high reliability.

    摘要: A variable speed drive (VSD) can be used to vary the voltage-to-frequency ratio (V/f) supplied to a compressor motor of a heating, ventilation, air conditioning or refrigeration (HVAC&R) system to make the motor stronger or weaker to compensate for varying conditions in the HVAC&R system. The VSD and corresponding control system or algorithm can monitor an operating parameter of the HVAC&R system, such as the kW absorbed by the motor, and then raise or lower the V/f of the VSD to obtain the lowest possible power consumption from the motor.

    摘要: A control system for operating a refrigerator appliance is provided. The refrigerator has a variable damper, a variable speed fan, and a variable speed compressor. The damper position, evaporator fan speed, and compressor speed are determined through interacting feedback control loops based on the set point temperatures for the fresh food and freezer compartments as well as the measured temperatures in such compartments. The adjustment of these actuators can eliminate large temperature fluctuations and discontinuities in the air flow and improve the thermal performance and energy efficiency of the refrigerator.

    摘要: In various implementations, a request for operation of an air conditioner may be received. The air conditioner may include a cooling mode and/or a dehumidifying mode. In some implementations, a compressor speed for a compressor of the air conditioner may be determined, and which mode(s) of the air conditioner to allow may be determined based at least partially on the determined compressor speed.

    摘要: Methods and apparatus control the temperature of an electronic component of a computer. A temperature sensor is read that measures a temperature of an electronic component of a computer. The speed of a compressor is adjusted based on the read temperature to maintain a pre-defined temperature range for the electronic component. The compressor compresses a refrigerant. The refrigerant is sent to a condenser that condenses the refrigerant. The refrigerant is sent to a heat exchanger that is thermally coupled to the electronic component and that transfers thermal energy from the electronic component to the refrigerant. Finally, the refrigerant is sent back to the compressor. Solenoid valves can be used to control the flow of refrigerant to heat exchangers for one or more additional electronic components.

The comparison module is configured to compare the current load to a previous load of the compressor to generate a comparison signal based on the comparison. The control module is configured to generate (i) a first control signal based on a superheat value of the compressor, and (ii) a second control signal based on the current load and the previous load. The control module is configured to, based on the comparison signal, control a position of an expansion valve according to either the first control signal or the second control signal.
