The connection of two element internals.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
As shown in figure 1, a kind of air conditioning system of the accumulation of heat defrost providing for the present invention, including refrigerant loop, described system
Refrigerant circuit is provided with compressor 1, indoor heat exchanger 4, throttling arrangement 5, outdoor heat exchanger 6 and is used for changing refrigerant flow direction
Reversal valve 2, it also includes thermophore 3, is provided with heat-exchange tube 13 in described thermophore 3, described heat-exchange tube 13 and described room
Interior heat exchanger 4 is arranged in parallel, and described heat-exchange tube 13 and described indoor heat exchanger 4 all optionally access described cold-producing medium
Loop, is all optionally accessed refrigerant loop herein and refers to, can be all connected with into system with heat-exchange tube 13 and indoor heat exchanger 4
Refrigerant circuit is it is also possible to any one is independently accessed.
Wherein, described thermophore 3 includes insulation shell 12 and the heat-storing material 14 in described insulation shell 12, described
Heat-exchange tube 13, in described insulation shell 12, carries out heat exchange with described heat-storing material 14, in defrost, heat-exchange tube 13
Temperature reduces, and to heat heat-exchange tube 13 by heat-storing material 14 heat release.
The switching of pipeline for convenience, the two ends of described indoor heat exchanger 4 are provided with regulating valve 8,9；Described heat-exchange tube 13
Two ends be provided with regulating valve 7,10, described regulating valve is preferably electronic valve, in order to automatically control.
