Please refer to Fig. 5, Fig. 5 is the structural representation of solar airconditioning under the 4th kind of operating mode among Fig. 1.

In summer or other seasons, solar energy resources is unnecessary need not to freeze, heat or produce under the operating mode of life with hot water; As shown in Figure 5; Because the high temperature heat conductive oil that solar thermal collector 1 flows out is via first pipeline 11; Flow in the high temperature intake line 31, and then this high temperature heat conductive oil is stored in the high-temperature heat-storage unit 3.Simultaneously, as shown in Figure 5, the low temperature conduction oil in the low temperature heat storage units 2 passes through driving pump by low temperature intake line 41, and then is pumped in second pipeline 12 by second pump 83, and then gets into heating in the solar thermal collector 1, obtains high temperature heat conductive oil, realizes circulation.

In summer or other seasons, no solar radiation and do not need under the operating mode of afterburning, refrigeration; As shown in Figure 6; High temperature heat conductive oil in the high-temperature heat-storage unit 3 pumps in the high temperature output pipe 32 through driving pump; And then pass through in the high temperature intermediary pipeline 33 entering high temperature intake lines 31, and then flow back in first pipeline 11 by high temperature intake line 31, and then get in the main heat exchanger 2; Certainly, during afterburning, as shown in Figure 7 if desired, through the high temperature heat conductive oil in the high temperature output pipe 32, can heat but directly get in the heating unit 7 without high temperature intermediary pipeline 33, and then get into again in first pipeline 11.Simultaneously, like Fig. 6 and shown in Figure 7, the low temperature conduction oil that obtains through main heat exchanger 2 is via second pipeline 12, and then through low temperature intake line 41, is stored in the low temperature heat storage units 4.

On these two kinds of operating modes, the process of refrigerastion in second closed circuit is identical with process of refrigerastion mentioned above, repeats no more at this.Certainly, of second kind of operating mode of preceding text under these two kinds of operating modes, can also produce life and use hot water, repeat no more at this.

Please refer to Fig. 8, Fig. 8 is the work sketch map of solar airconditioning under the 7th kind of operating mode among Fig. 1.

Spring and autumn, have solar radiation and enough, when producing the domestic hot-water; As shown in Figure 8, by the high temperature heat conductive oil of solar thermal collector 1 outflow, after 11 outflows of first pipeline; Not through main heat exchanger 2; But directly get in the heat supplying pipeline 51, and then carry out heat exchange in the entering boiler 5, producing life and using hot water.Then, as shown in Figure 8, the low temperature conduction oil that is flowed out by boiler 5 flows back in the solar thermal collector 1 via second pipeline 12, through heating, obtains high temperature heat conductive oil again, realizes circulation.

Please refer to Fig. 9, Fig. 9 is the work sketch map of solar airconditioning under the 8th kind of operating mode among Fig. 1.

In the winter time, have solar radiation and enough, when heating, high temperature heat conductive oil is directly got in the main heat exchangers 2 by first pipeline 11, the low temperature conduction oil that is flowed out by main heat exchanger 2 then flows back in the solar thermal collector 1 through second pipeline 12.Simultaneously, as shown in Figure 9, the high-temperature water medium that is flowed out by main heat exchanger 2 directly gets in the heating pipeline 63 through the 3rd pipeline 21, and then gets into process heat exchange in the fan coil 62, realizes heating.Then, thereby the water at low temperature medium that fan coil 62 flows out flows back in the heat exchanger 2 through the 4th pipeline 22, and realization circulates.

Need to prove, in this operating mode, as solar radiation but when not enough, when needing afterburning, the course of work of conduction oil is identical with above-mentioned the third operating mode, repeats no more at this; When no solar radiation and when not needing afterburning, the course of work of conduction oil is identical with above-mentioned the 5th kind of operating mode, repeats no more at this; When no solar radiation and need afterburning, the course of work of conduction oil coexists with above-mentioned the 6th kind of operating mode mutually, and this repeats no more.

Need to prove that to shown in Figure 9, the link position between first pipeline 11 and the high temperature intake line 31 is provided with the sign flag that three little triangles are formed like Fig. 1, this sign flag is a control valve 81, specifically can be triple valve; Through manual control or procedure auto-control, can control the flow direction of this control valve 81; Such as, as shown in Figure 2, high temperature heat conductive oil when this control valve 81, through manual control or procedure auto-control, can be so that high temperature heat conductive oil flow to high temperature intake line 31, but continue in first pipeline 11, to flow; As shown in Figure 3, during this control valve 81 of high temperature heat conductive oil process, through manual control or procedure auto-control, high temperature heat conductive oil can flow in the high temperature intake line 31, rather than continues in first pipeline 11, to flow.Obviously, under each operating mode, the flow direction of the control valve 81 between first pipeline 11 and the high temperature intake line 31 can preestablish through control program in the control system, thereby be implemented under the different operating modes, realizes the corresponding flow direction.The triangular marker that is provided with between other loops (comprise three leg-of-mutton for triple valve; Comprise that two triangles are two-port valve, this two-port valve is equivalent to switch, comprises that four triangles are cross valve); Also be control valve 81; Its flow direction also can preestablish through control program in the control system, thereby is implemented under the different operating modes, realizes the corresponding flow direction.Certainly, the change of the flow direction of control valve 81 also can realize through manual operation.
