Abstract: An air conditioner and a method for calculating an operating parameter of an indoor unit are provided. The air conditioner includes an outdoor unit, an indoor unit, and a controller. The controller is configured to: in a case where the air conditioner is in a cooling state, determine an operating parameter of the indoor unit in a second cooling state according to a heat exchange area, a heat exchange coefficient, and a heat exchange temperature difference of an indoor heat exchanger; and determine an operating parameter of the indoor unit in a first cooling state according to a superheat degree of an outlet of the indoor heat exchanger in the first cooling state, a superheat degree of the outlet of the indoor heat exchanger in the second cooling state, and the operating parameter of the indoor unit in the second cooling state.

Abstract: An air conditioner and a control method of an air conditioner are provided. The air conditioner includes an outdoor unit, an indoor unit, a refrigerant circulation loop, and a controller. The controller is configured to determine whether the air conditioner is operating in a cooling mode; obtain a first target supercooling degree in a first standard condition if it determined that the air conditioner is operating stably in the cooling mode; convert a supercooling degree in a current condition into a supercooling degree in the first standard condition; obtain a first refrigerant amount difference according to the first target supercooling degree, the supercooling degree in the first standard condition, an outdoor unit internal volume in the first standard condition, and an outdoor unit internal volume in the current condition; and determine a refrigerant amount of the air conditioner according to the first refrigerant amount difference.

Abstract: An air conditioner includes an indoor unit, an outdoor unit, and a controller. The outdoor unit is connected to the indoor unit, and the outdoor unit includes a housing, a compressor, a four-way valve, an outdoor fan, a separating device, and a plurality of outdoor heat exchangers arranged in parallel.
