A return air superheat degree test method for a multi-split system. A multi-split system comprises a re-cooling loop composed of a first heat exchanger (100) and a second heat exchanger (200), a first temperature sensor (11), a second temperature sensor (12) and a third temperature sensor (13). The return air superheat degree test method comprises the following steps: acquiring a first temperature value (T1) detected by the first temperature sensor (11), a second temperature value (Tintermediate) detected by the second temperature sensor (12) and a third temperature value (T2) detected by the third temperature sensor (13); acquiring a minimum value between the first temperature value (T1) and the second temperature value (Tintermediate), and acquiring a maximum value between the third temperature value (T2) and the second temperature value (Tintermediate); and calculating a superheat degree according to the minimum value and the maximum value. |
