The application provides an
air conditioning system, an air conditioner and a control method. The
air conditioning system comprises a first
refrigeration system and a second
refrigeration system, the first
refrigeration system and the second refrigeration system are arranged in parallel, a regulating condenser is arranged in parallel with the first refrigeration system and the second refrigeration system, the regulating condenser is communicated with a
refrigerant storage device, and the first refrigeration system and the second refrigeration system are respectively communicated with the
refrigerant storage device; the
refrigerant storage device respectively stores the refrigerant from the first refrigeration system, the second refrigeration system and the regulating condenser, or respectively releases the refrigerant into the first refrigeration system, the second refrigeration system and the regulating condenser. The regulating condenser and the refrigerant storage device are added to the original
air conditioning system, the refrigerant storage device can regulate the first refrigeration system and the second refrigeration system with different cold energy requirements respectively, the air conditioning system is effectively protected, the
system pressure is regulated, and the system load is prevented from being too heavy.
