In the present embodiment, by arranging the first heat-exchange system and second heat-exchange system of separate operation, when any one
When individual heat-exchange system breaks down, all do not interfere with the properly functioning of another heat-exchange system, so can wherein one change
When hot systems breaks down, run by controlling another heat-exchange system, cabin or room etc. can be continuously heating capacity is provided
Or refrigerating capacity, ensure the normal work of unit, improve the redundant of unit.
The screw unit of the present invention, by shared First Heat Exchanger or first heat-exchange system and second of the second heat exchanger
Heat-exchange system, and by arranging the first separate control system and the second control system, it is possible to control the first heat-exchange system
Run with the second heat-exchange system simultaneously or single run alone, when any one heat-exchange system breaks down, another all without impact
The operation of one heat-exchange system, therefore improves the redundant of unit；Further, compared to traditional single system unit, reduce
The floor space of unit so that the space structure of unit is compact.
It should be noted that when element is referred to as " being fixed on " another element, and it can be directly on another element
Or element placed in the middle can also be there is.When an element is considered as " connection " another element, and it can be to be directly connected to
To another element or may be simultaneously present centering elements.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
