Air conditioner control method and device, air conditioner and storage medium

The invention discloses a control method and device for an air conditioner, the air conditioner and a storage medium, and the method comprises the steps that after the air conditioner is started in a refrigeration mode, a compression refrigeration system and an adsorption refrigeration system are controlled to be started and run; on-off of the first switch module, on-off of the second switch module and on-off of the valve assembly are jointly controlled by combining the current temperature of an adsorbent in the adsorption bed, the current refrigerant amount in the second condenser and the current refrigerant amount in the second evaporator. The adsorption type refrigerating system completes refrigerating circulation through solar energy, condensate water generated by the first evaporator and heat dissipated by the first condenser, and the adsorption type refrigerating system and the compression refrigerating system provide cooling capacity for the indoor unit together. According to the scheme, in the refrige
