Abstract: A method and an apparatus for controlling an air conditioner are provided, and the air conditioner is also provided. Herein, the method for controlling the air conditioner may include: acquiring at least one operating environment parameter of the air conditioner; determining a target temperature of the air conditioner and a revolving speed of an internal fan according to the at least one operating environment parameter of the air conditioner; and adjusting a frequency of a compressor on the basis of the operating environment parameter and the target temperature of the air conditioner and the revolving speed of the internal fan.

Abstract: A heat pump air conditioning system and a control method. The heat pump air conditioning system includes: a compressor; an indoor unit heat exchanger, an outdoor unit heat exchanger and a throttling device; a refrigerant circulation loop, connecting the compressor, the indoor unit heat exchanger, the outdoor unit heat exchanger and the throttling device in series; the heat storage module, disposed in the refrigerant circulation loop and configured to absorb heat from refrigerant in the refrigerant circulation loop and store heat when heat storage is required, and to heat the refrigerant in the refrigerant circulation loop when the outdoor unit heat exchanger defrosting is required. The heat pump air conditioning system can store excess heat of the system for defrosting when indoor heat load is low, and release heat for defrosting by means of the heat storage module during a defrosting process while continuing supplying heat to a room.

Abstract: A winding device for a blind without pull cords is provided with a reel pivotal base and a cord-guiding base abutting against each other in the upper rail of a blind. A winding reel is axially assembled on the reel pivotal base, having its outer circumference formed with an oblique conical surface gradually shrinking from its first end to its second end to enable a linking cord to move forward automatically when the linking cord is wound on the winding reel. The cord-guiding base is provided with at least one push block at a location where the winding reel is pivotally rotated for guiding the linking cord to be wound side by side closely on the winding reel, preventing the linking cord from overlapping or wound irregularly after the linking cord is wound on the winding reel, enabling a blind to be collapsed or stretched smoothly.
