Control method and device of window type air conditioner, window type air conditioner and storage medium

The invention provides a control method and device of a window air conditioner, the window air conditioner and a storage medium. By responding to a switching instruction of a mute operation mode, the indoor temperature, the environment humidity and the carbon dioxide concentration of the environment corresponding to the window air conditioner are obtained; then according to the indoor temperature, the environment humidity and the carbon dioxide concentration, a target frequency control curve is determined; further determining a fan control curve according to a compressor noise value corresponding to the frequency in the target frequency control curve and a preset noise threshold value; and controlling a compressor of the window air conditioner to operate according to the target frequency control curve, and controlling a fan of the window air conditioner to operate according to the fan control curve. According to the method, the fan acting and the frequency acting are mutually matched and mutually restricted,
