The invention discloses an air pipe type indoor air conditioner and a control method thereof. The air pipe type indoor air conditioner comprises a casing, an indoor heat exchanger and an indoor fan, wherein an air return inlet and an air outlet are formed in the casing; the indoor heat exchanger is arranged in the casing and positioned between the air return inlet and the air outlet; the indoor fan is arranged in the casing on one side of the indoor heat exchanger; the air outlet comprises a front air outlet formed in the front side wall of the casing and a lower air outlet formed in the lower side wall of the casing; the indoor air conditioner further comprises a switching mechanism for opening and closing the front air outlet and the lower air outlet. The air pipe type indoor air conditioner disclosed by the invention can adopt two air-out manners of the front air outlet and the lower air outlet, the manners of the front air outlet and the lower air outlet can be automatically selected according to the operational mode of the air conditioner, such as under the refrigeration mode and the dehumidification mode, the manner of the front air outlet is selected, and under the heating mode, the manner of the lower air outlet is selected, so that comfort of a refrigeration room and a heating room is considered, and the optimal comfort in the air regulation of the room is realized.

The invention discloses a control method of a central air conditioning load response to HVDC locking accident. The control method comprises the following steps that measuring information of an air conditioner is collected in real time, the information comprises setting cooling water entering and exiting temperature, cooling water entering and exiting temperature and central air conditioner main unit power and the like; when the HVDC locking accident occurs, a safe and stable load shedding main station issues load shedding instructions through a communication protocol; a load substation executes the load shedding instructions, the load substation excises the controlled central air conditioning load by the communication protocol; feeder power supply is restored, and the current percentage ofthe air conditioner is controlled to be the same as that before the accident; limitation on the percentage of air conditioning current is lifted; a full time domain simulation model is established; and a dispatching center grasps changes of the system frequency after the load is added to the control through the full time domain simulation model. The control method can quickly respond to the HVDClocking accident. Impact on the central air conditioner is little. Secondary power shocks to the system are avoided. The power grid dispatching center mastering the frequency response after the accident is facilitated.
