The invention provides an air conditioner refrigerant leakage alarm device and method and an air conditioner system.The device comprises a mechanical pressure gauge, an alarm module and an alarm, and the mechanical pressure gauge is connected with a refrigerant air pipe between an air conditioner indoor unit and an air conditioner outdoor unit and used for measuring pressure data of the refrigerant air pipe; an alarm circuit is arranged in the alarm module, a pressure pointer of the mechanical pressure gauge is connected in series in a circuit loop of the alarm circuit, and the pressure pointer rotates based on the change of the pressure data when the refrigerant in the refrigerant air pipe leaks, so that the circuit loop is conducted, and a corresponding alarm trigger instruction is generated; the alarm is connected with the alarm module and is used for playing an alarm signal after receiving the alarm triggering instruction. According to the invention, the mechanical pressure gauge is arranged at the refrig
