Description
Technical field
The utility model relates to a kind of large-capacity multiple air conditioner accent/source pump, belongs to the refrigeration and air-conditioning technical field, is specially adapted to cooling and heat supply in many rooms, big cold/heat supply area building.
Background technology
Independently control, use flexibly because multi-connected air conditioner/source pump has indoor set, favorable expandability, take installing space little, can not establish outstanding advantages such as special-purpose machine room, so be rapidly developed since Japan is born from nineteen eighty-two, become one of central air conditioner system form the most active in the medium and small building at present.The characteristics of multi-connected air conditioner/source pump are mainly 2 points: first indoor units is many, and it two is a kind ofly to constitute the cooling/heating system that a kind of refrigeration cycle forms by outdoor unit and indoor units by connecting line.
For the building of many rooms, less cold/heat supply area, adopt the outer unit 15 of a module chamber as shown in Figure 1, construction at the construction field (site), liquid tube connector collector, gas connection pipe collector, liquid/gas tube connector branch pipe, liquid tube connector arm, gas are installed are managed arm in succession and constitute single refrigeration/heating recycle systems, directly provide air after overheated wet process to one or several zones or room with many direct vaporation-type indoor sets 14 as shown in Figure 2.
And for the bigger occasion of cold/heat supply area, the technical scheme of prior art is: at the construction field (site), outer unit 15 parallel connections of several module chamber are assembled into the outdoor unit of high-capacity moduleization, manage the refrigerating/heating circulatory systems that arm and several direct vaporation-type indoor set 14 as shown in Figure 2 constitutes as shown in Figure 3 in succession by liquid tube connector collector, gas connection pipe collector, liquid/gas tube connector branch pipe, liquid tube connector arm, gas again, directly provide air after overheated wet process to one or several zones or room.The constructive method of the outdoor unit of high-capacity moduleization is: pass through site operation, with many as shown in Figure 1 three class interfaces on the outer unit of module chamber be that liquid line interface A, flue interface B link to each other with oil equalizing pipe interface C is corresponding respectively, promptly constitute the outdoor unit of high-capacity moduleization.The general export of liquid line interface A, flue interface B is the liquid tube connector collector that the outdoor unit of high-capacity moduleization after the assembling combination links to each other with indoor units, the liquid line interface and the gas interface tube of gas connection pipe collector.
