Beschreibung
Zusammenfassung:	A heat pump unit control system, comprising a heat exchanger (1), a compressor (2), a first switch component (3), a second switch component (4), an enhanced vapour injection electronic expansion valve (5) and a main electronic expansion valve (6). A first end (22) of the compressor (2) is sequentially connected to a first port (7) of the heat exchanger (1) via the first switch component (3) and the enhanced vapour injection electronic expansion valve (5), a second port (8) of the heat exchanger (1) is connected to a jet end (21) of the compressor (2), the end of the first switch component (3) connected to the compressor (2) is connected to a third port (9) of the heat exchanger (1), a fourth port (10) of the heat exchanger (1) is connected to a second end (23) of the compressor (2) via the main electronic expansion valve (6), and the end of the first switch component (3) connected to the enhanced vapour injection electronic expansion valve (5) is connected to the fourth port (10) of the heat exchanger (1) via the second switch component (4).
