Abstract: The present disclosure provides a method for testing an internal force increment of an arch bridge suspender by inertial measurement, including the following steps: (1) selecting a suspender to be tested with internal force increment, and mounting an acceleration sensing device or a speed sensing device at a lower edge of the suspender to be tested; (2) setting an appropriate sampling frequency and collecting signals; (3) processing information data collected in step (2) by using Formulas; and (4) recording a result of the information data processing and obtaining the internal force increment of the suspender. The method can obtain the internal force increment of the suspender by collecting acceleration or speed signals of the lower edge of the suspender and performing calculation from the signals. This method has the advantages of simple and convenient testing, high replicability and low test cost.

Abstract: The disclosure discloses an air sweeping mechanism and an air conditioner with the air sweeping mechanism. The air sweeping mechanism includes: a mounting portion, the mounting portion being configured to be mounted on a housing of the air conditioner; an air sweeping blade, the air sweeping blade being connected with the mounting portion; and a driving rod, the driving rod being connected with the air sweeping blade, and a position of the driving rod being adjustably disposed, wherein the air sweeping blade and the driving rod are integrally formed, at least part of the air sweeping blade is a flexible portion, and the driving rod drives the at least part of the air sweeping blade to move.

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: Disclosed are a centrifugal fan blade assembly and a centrifugal fan, comprising a plurality of blades, a blade leading edge of at least some of the blades being provided with an interference groove, the interference groove extending in a width direction of the blade. By providing the interference groove extending in the width direction of the blade on the blade leading edge, when the fan blade assembly is running, the interference groove changes noise frequency, thereby preventing the blade leading edge from producing a relatively large broadband noise after being impacted by a high speed air flow, thus effectively reducing noise.

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.
