摘要： The present disclosure discloses an air conditioner controlling method and apparatus, as well as an air conditioner having the same. The air conditioner operates in a low temperature hybrid mode. The method includes: determining that an outdoor heat exchanger of the air conditioner operates in an evaporator state; acquiring a state signal of a refrigerant of an indoor refrigerating unit; and adjusting an opening degree of an electronic expansion valve of an outdoor unit according to the state signal of the indoor refrigerating unit. This method may adjust the opening degree of the electronic expansion valve of the outdoor unit according to the state signal of the indoor refrigerating unit when the outdoor heat exchanger of the air conditioner operates in the evaporator state, thereby effectively improving the reliability of control, broadening the reliable operation range of the system, and reasonably distributing the refrigerant between the indoor refrigerating unit and the outdoor unit under a low temperature working condition.

摘要： The present disclosure provides a control method, apparatus, and device for a compressor, a storage medium, and a refrigerator system. The control method includes: obtaining an electrical parameter, a return air parameter, and a first frequency of the compressor during operation of the compressor; determining a first fitting formula corresponding to the first frequency; obtaining an exhaust pressure by inputting the electrical parameter and the return air parameter into the first fitting formula for calculation; and controlling the compressor based on the exhaust pressure. In this way, the pressure sensor disposed on an exhaust side of an air conditioner can be omitted, i.e., a physical pressure sensor on the exhaust side is not needed, hence cost is saved; or for the air conditioner with the pressure sensor on the exhaust side, when the pressure sensor on the exhaust side is damaged, the above manner for calculation can be an alternative to obtaining the exhaust pressure, which ensures a user's normal use and thus improves the user experience.

摘要： Disclosed are a temperature adjustment device, a control method therefor, a control apparatus thereof, and a storage medium. The method comprises: acquiring a current demand load of a co-cooling and co-heating area of the temperature adjustment device; acquiring current operating parameters of the temperature adjustment device; according to the current operating parameters and demand load, determining target operating parameters of the temperature adjustment device; and according to the target operating parameters, adjusting an operating state of the temperature adjustment device. In the method, the operating state of the temperature adjustment device is adjusted according to the current demand load and operating parameters of the co-cooling and co-heating area, which detects the load demands of the co-cooling and co-heating area, and controls the temperature adjustment device according to the detected load demands. Thus, the number of times the temperature adjustment device starts and stops may be reduced, which prevents frequent starting and stopping, and enables the temperature adjustment device to operate in an energy-saving manner.

摘要： The present disclosure provides a method and device for position determination, an air conditioning system, and a readable storage medium. The method for position determination includes: acquiring return air temperature information of each indoor unit; determining a first correlation coefficient between every two indoor units based on the return air temperature information; classifying a plurality of indoor units based on the first correlation coefficient to obtain a set number of classified groups; and generating relative position information in each classified group based on the first correlation coefficient by taking any one of the indoor units as a locating point. Maintenance personnel are not required to manually maintain a relative position relation of the plurality of indoor units. Therefore, the maintenance difficulty of the relative position relation of the plurality of indoor units is reduced, and a time cost and a labor cost required for maintenance are reduced accordingly.
