Zusammenfassung:	PURPOSE: An air conditioning practice device capable of recovering and refilling coolant is provided to increase or decrease the number of evaporators easily by using detachable connectors. CONSTITUTION: An air conditioning practice device(1) capable of recovering and refilling coolant comprises a sensor unit(50), a coolant recovering and refilling unit(60), and a control unit. The sensor unit measures one or more elements of the pressure, the temperature, the flow quantity of coolant. The coolant recovering and refilling unit is installed between an evaporation unit and a compression unit and restores the coolant supplied to the compression unit from the evaporation unit or refills coolant to the compression unit. The control unit controls the operation of the coolant recovering and refilling unit according to the measured results.
