摘要： A refrigeration system includes a high-pressure side with a gas cooler configured, while the refrigeration system is powered by a main power supply and is operating to provide refrigeration, to cool refrigerant on the high-pressure side. The refrigeration system includes a low-pressure side with one or more evaporators. The refrigeration system includes an auxiliary compressor coupled to a backup power supply. An input of the auxiliary compressor is coupled to fluid conduit of the low-pressure side, and an output of the auxiliary compressor is coupled to fluid conduit of the high-pressure side. A controller is communicatively coupled to the auxiliary compressor. After determining that the main power supply is unavailable, the controller causes the auxiliary compressor to turn on to move refrigerant from the low-pressure side to the high-pressure side.

摘要： An anti-slugging control method and control apparatus for an air-conditioning system. The control method includes obtaining a discharge superheat DSH of a compressor in real time, and monitoring the DSH during operation of the air-conditioning system (S10); controlling a timer to start timing if the DSH is less than a first preset value M1 continuously for a first preset time t1, and controlling an outdoor unit of the air-conditioning system to stop to prevent slugging from occurring in the compressor when a measured time t of the timer reaches a second preset time t2. The DSH in the air-conditioning system is monitored in real time, such that a refrigerant drawn back to an air return port of the compressor can be ensured to be in a completely gaseous state, thereby preventing a liquid refrigerant from entering the compressor and preventing slugging. In addition, because a value of the discharge superheat is relatively large, it is convenient to inspect and control data, thereby improving the precision of anti-slugging control, and operating safety and reliability of the air-conditioning system.

摘要： Provided is an air conditioning apparatus that is capable of suppressing increases in volume and cost of the apparatus and performing more suitable overheating protection. An electric compressor is an inverter-integrated electric compressor integrally including a compressor, an electric motor that drives the compressor, and an inverter including a temperature sensor that detects the temperature in the vicinity of a semiconductor switching device, wherein a controller estimates a discharge temperature of the compressor on the basis of a correlation of respective pressure loading characteristics for the detected temperature of the inverter, for the rotational speed of the compressor, and for the motive force of the compressor in a refrigerating cycle.

摘要： It is determined whether thermo-off postponement control is allowed or not on the basis of a current compressor operating frequency when a thermo-off condition is satisfied. If it is determined that thermo-off postponement control is allowed, the thermo-off postponement control in which a lowest operating frequency in an operating frequency range of a compressor is temporarily reduced within a range greater than or equal to a minimum operating frequency of the compressor in use so as to continue an operation. If it is determined that thermo-off postponement control is not allowed, thermo-off of stopping the compressor is performed.

摘要： A method for controlling an electric compressor into which an inverter for controlling an electric motor as a drive source is integrally incorporated. The method is characterized by comprising the steps of acquiring the temperature of an accessory of the inverter, when the acquired temperature becomes or is already equal to or higher than the maximum rated temperature of the accessory, calculating the value of a current which can flow at the acquired temperature and restrictively controlling the rotational speed of the electric compressor such that the input current becomes equal to or less than the value of the current which can flow, and when the temperature of the accessory becomes lower than the maximum rated temperature, releasing the restrictive control. The method for controlling the electric compressor can prevent a malfunction of the accessory even in use under a high-temperature environment while preventing increase in the cost and size of the electric compressor by preventing an increase in the size of the accessory of the inverter.
