Specific embodiment
Combined with specific embodiments below, the present invention is furture elucidated, and embodiment is under the premise of the technical scheme of the present invention Implemented, it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in Figure 1, a kind of fluid reservoir with backheating function, including cylinder 1, the upper end of cylinder 1 is provided with fluid reservoir Air inlet 11 and fluid reservoir gas outlet 12, fluid reservoir air inlet 11 and fluid reservoir gas outlet 12 pass through the centre in cylinder 1 Conduit 3 is connected to, and the spiral helicine high-temperature spiral pipe 4 being arranged around intermediate conductor 3 is provided in cylinder 1.
The upper end of cylinder 1 is arranged in fluid reservoir air inlet 11, and the lower end of cylinder 1 is arranged in fluid reservoir gas outlet 12;
For the pipeline that 4 high-temp liquid of high-temperature spiral pipe flows through, the import setting of high-temperature spiral pipe 4 is in upper end, outlet setting In lower end, to increase mean temperature difference.
The outer surface of high-temperature spiral pipe 4 is provided with round fin (not shown).The settable circle outside high-temperature spiral pipe 4 Fin is to increase heat exchange area to increase heat exchange efficiency.
Low-temperature refrigerant flows from up to down in the cylinder 1 of fluid reservoir, with the part heat drawn in high-temperature spiral pipe 4 Amount, the liquid refrigerant of non-evaporating completely is evaporated to gaseous state before.The high-temp liquid flowed out from condenser simultaneously passes through high temperature Liquid inlet flows through high-temperature spiral pipe 4, the degree of supercooling of high-temp liquid is improved by exchanging heat, finally by high-temp liquid outlet stream Out.
The upper end of intermediate conductor 3 is provided with strainer 5 and supports the support frame 6 of strainer 5, during support frame 6 is fastened around Between conduit 3 periphery.Oil return opening 31 is provided on intermediate conductor 3.
A kind of air-conditioning system with the fluid reservoir with backheating function, including indoor end 7, outdoor is also disclosed in the utility model End 8, compressor 9, fluid reservoir 10, the first four-way reversing valve 13 and the second four-way reversing valve 14, indoor end 7 and the first four-way commutate Valve 13 connects, and the first four-way reversing valve 13 is connect with the outlet of compressor 9, fluid reservoir air inlet 11 and outdoor end 8 respectively;It is outdoor End 8 is connect with the second four-way reversing valve 14, the second four-way reversing valve 14 respectively with the import of high-temperature spiral pipe 4, high-temperature spiral pipe 4 Outlet and indoor end 7 connect.
