Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings, but not as to this practicality
New restriction.
Being in of the main innovation of air conditioning system (particularly a kind of multi-connected machine VRV air conditioning system) in this utility model
In increased cold-storage and regenerative apparatus in air conditioning system.
As shown in figure 1, one end of the compressor 1 in this air conditioning system is connected with the first end of cross valve 2 by oil 19,
Second end of cross valve 2 is connected by one end of outdoor heat exchanger 3, and the other end of outdoor heat exchanger passes through the first pipeline and interior
The first end of heat exchanger 4 connects, the second end of indoor heat exchanger 4 through the three-terminal link of the second pipeline and cross valve 2, and four
4th end of port valve 2 is then connected with the other end of compressor 1 by gas-liquid separator 18.Wherein, the number of indoor heat exchanger 4 is
Multiple, and these indoor heat exchangers 4 are together in parallel.
In order to realize the recovery storage to cold and hot energy, this utility model increased cold-storage device 5 He in air conditioning system
Regenerative apparatus 6, wherein, cold-storage device 5 for the cold-storage in refrigerating operaton or lets cool, and regenerative apparatus 6 is used in heating operation
Accumulation of heat or heat release.For this reason, cold-storage device 5 is arranged in parallel with the first pipeline, the outfan of cold-storage device 5 and second pipe simultaneously
Road connect, thus in running constitute two can break-make control branch road, to select whether coolant flows through cold-storage device 5
And/or indoor heat exchanger 4.Similarly, the second pipeline is connected with the first pipeline by regenerative apparatus 6, and the output of regenerative apparatus 6
End is connected with the second pipeline, thus in running composition two can break-make control branch road, to select whether coolant flows through
Regenerative apparatus 6 and/or indoor heat exchanger 4.
For example, in refrigeration, carry out cold-storage using cold-storage device 5 and let cool, simultaneously close off regenerative apparatus 6；Otherwise in system
When hot, then carry out accumulation of heat and heat release using regenerative apparatus 6, simultaneously close off cold-storage device 5.
