Provided are a defrosting control device, an air conditioner and a defrosting control method therefor. The device includes an airbag device, wherein the airbag device includes a mounting support (), an airbag () and an inflation mechanism. When an air conditioner to be controlled enters a defrosting mode, the inflation mechanism inflates the airbag () such that same forms an airbag layer to isolate an outdoor heat exchanger of the air conditioner to be controlled from flowing air outside the outdoor heat exchanger. The defrosting control device can achieve the beneficial effects of a small defrosting heat loss, a good defrosting effect and a good user experience.

Defrosting control device, air conditioner and defrosting control method therefor

The present disclosure discloses an air conditioner control method and system, a non-transitory storage medium and a processor. The control system includes an environmental temperature sensor configured to detect a first temperature value of an external environment of a target object; a heat exchanger temperature sensor configured to detect a second temperature value of an outside heat exchanger of an air conditioner system; a speed monitoring system configured to detect a driving speed of the target object; and a control system, connected to the environmental temperature sensor, the heat exchanger temperature sensor and the speed monitoring system, and configured to determine according to the first temperature value, the second temperature value and the driving speed, whether the air conditioner system enters a defrosting mode in a case that the air conditioner system operates in a heating mode.

Air conditioner control method and system, storage medium and processor

A heat pump air conditioner assembly for an electric vehicle and a control method thereof, and an electric vehicle with the heat pump air conditioner assembly for the electric vehicle are provided. The heat pump air conditioner assembly includes a heat pump air conditioning system and a HVAC box body. An in-vehicle heat exchanger of the heat pump air conditioning system is located in the HVAC box body. An auxiliary heater is also arranged in the HVAC box body. The auxiliary heater is located at a leeward side of the in-vehicle heat exchanger. The heat pump air conditioning system is provided with a defrosting branch connecting with a refrigerant outlet of an external heat exchanger and a suction port of a compressor. When the heat pump air conditioning system is in a defrosting mode, the HVAC box body supplies air to the vehicle, the auxiliary heater is turned on.
