Characteristics of MRV
The branch mode of refrigerantpipe consists of free combinationof Y-type manifold pipe andcomb-shape manifold pipe.Branching again after comb-shape branch is realized for thefirst time in the same trade ofChina. So the branch position of
refrigerant pipe can be set freely,
thus can freely complete thedesign of shortest circuit andreduce the cost of construction.
1.
Indoor unit group can connect16 units, realizing the
combination of different capacity
and different configuration and
the connection of indoor unitgroup within 135% (except 6HP)of capacity of outdoor unit. Themax. number of connection ofindoor unit group: 16 for 10HPsystem; 9 for 6 HP system. Asmany units can be connected inthe indoor unit group, the
purpose of saving energy
reducing settings has beenrealized.
2.
30
m
(There is certain loss of capacity when the refrigerant
flows in the pipe. The sensory control compensates
the capacity of the indoor unit group).
50m 20m 20m 10m
The length of farthest refrigerantpipe after first branching will beincreases according to the numberof the unit increase in the group. Butthe allowable length from the firstbranch to the farthest unit groupshall be within 50 m.
3.
Sensory control can realize the capacitycompensation of indoor unit group.Using sensory control can conduct themost fine proportion control of indoorunit group within 50~100% of loadvariation. In addition, the control methodof capacity compensation suitable forimpedance of refrigerant pipe can also beused to guarantee the constant capacityof the indoor unit group so as to realizethe comfortable conditioning space
5.
The max. fall between unit group is 30 m;the max. fall between indoor unit andoutdoor unit is 50 m. In addition, oneoutdoor unit can realize to be
corresponding to 30 m fall and difference
of height of 8-storey building betweenindoor unit group, mostly suitable for the
longitudinal system such as elevator, etc.
