For ducted air conditioners, when a fire occurs indoors, if the air conditioner cannot be turned off in time, it will become a fire accelerant. If the unit is turned off or the power is directly cut off, but the valves cannot be closed in time, the fire may spread to the air conditioner. It will lead to greater losses. If the air supply valve is closed before the unit is shut down, the air duct may also be squeezed
In places where dangerous gas hazards exist outdoors, such as carbon monoxide, dangerous chemicals, methane, ethylene, toxic substances, PM2.5 exceeding the standard, etc., when dangerous gas occurs outdoors, if the fresh air outlet cannot be closed in time, the dangerous gas will enter with the air conditioner Indoors, if the air conditioner is directly turned off, it will affect the indoor demand for air conditioning

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] The present invention proposes an air conditioner and fire-fighting linkage control method, the method includes: simultaneously detecting indoor fire signals and outdoor dangerous gas signals, when detecting a fire in the room, automatically shutting down the air conditioner and corresponding valves, and alarming; When dangerous gas is detected outside, close the fresh air valve.
[0030] Specifically, after the unit is powered on or the power button is pressed in the standby state, the indoor fire signal is first detected. When the fire signal is detected, the unit and each valve do not operate, and the fire alarm is issued; when the fire signal is not detected, the following operations are performed. :
[0031] 1) The fire damper at the return air outlet is opened and adjusted to the target opening;
[0032] 2) The electric valve of the resid...

The invention discloses an air conditioner and fire protection linkage control method and system and an air conditioner. The control method comprises the steps that when it is detected that a fire occurs indoors, an air conditioner and a corresponding valve are automatically turned off, and the air conditioner is protected against damage by the fire; when it is detected that dangerous gas exists outdoors, a fresh air valve is turned off, indoor personnel safety is ensured, and meanwhile it is ensured that the air conditioner is normally used; and when a dangerous gas alarm is removed, the fresh air valve is turned on, and fresh air is provided indoors. Safety damage caused to the air conditioner when a fire occurs indoors is avoided, and therefore the loss is reduced to the minimum; and when dangerous gas exists outdoors, damage of dangerous gas to the indoor space can be cut off in time, and the air conditioner can normally operate.
Description
technical field [0001] The invention relates to the field of household appliances, in particular to an air conditioner linkage control method, a control system and an air conditioner. Background technique [0002] People's use of air conditioners is not only satisfied with its comfort, but also pursues its reliability and safety. For ducted air conditioners, when a fire occurs indoors, if the air conditioner cannot be turned off in time, it will become a fire accelerant. If the unit is turned off or the power is directly cut off, but the valves cannot be closed in time, the fire may spread to the air conditioner. It will lead to greater losses. If the air supply valve is closed before the unit is closed, the air duct may also be squeezed. In places where dangerous gas hazards exist outdoors, such as carbon monoxide, dangerous chemicals, methane, ethylene, toxic substances, PM2.5 exceeding the standard, etc., when dangerous gas occurs outdoors, if the fresh air outlet cannot...
